Verse 1

(iii. Tr. c. 10) He doth not say that the day, or the time, but that the hour is come. An hour contains a portion of a day. What was this hour? He was now to be spit upon, scourged, crucified. But the Father glorifies the Son. The sun failed in his course, and with him all the other elements felt that death. The earth trembled under the weight of our Lord hanging on the Cross, and testified that it had not power to hold within it Him who was dying. The Centurion proclaimed, Truly this was the Son of God. (Matt. 27:54) The event answered the prediction. Our Lord had said, Glorify Thy Son, testifying that He was not the Son in name only, but properly the Son. Thy Son, He saith. Many of us are sons of God; but not such is the Son. For He is the proper, true Son by nature, not by adoption, in truth, not in name, by birth, not by creation. Therefore after His glorifying, to the manifestation of the truth there succeeded confession. The Centurion confesses Him to be the true Son of God, that so none of His believers might doubt what one of His persecutors could not deny. (iii. de. Trin) But perhaps this proves weakness in the Son; His waiting to be glorified by one superior to Himself. And who does not confess that the Father is superior, seeing that He Himself saith, The Father is greater than I? But beware lest the honour of the Father impair the glory of the Son. It follows: That Thy Son also may glorify Thee. So then the Son is not weak, inasmuch as He gives back in His turn glory for the glory which He receives. This petition for glory to be given and repaid, shows the same divinity to be in both.
Hilary of Poitiers · d. 367Catena Aurea (Aquinas, 1274)
"Father, the hour is come; glorify Thy Son, that Thy Son also may glorify Thee." Again He showeth us, that not unwilling He cometh to the Cross. For how could He be unwilling, who prayed that this might come to pass, and called the action "glory," not only for Himself the Crucified, but also for the Father? since this was the case, for not the Son only, but the Father also was glorified. For before the Crucifixion, not even the Jews knew Him; "Israel," it saith, "hath not known Me" (Isa. i. 3); but after the Crucifixion, all the world ran to Him.
John Chrysostom · d. 407Homilies on John
(Hom. lxxx) After having said, In the world ye shall have tribulation, our Lord turns from admonition to prayer; thus teaching us in our tribulations to abandon all other things, and flee to God. (Hom. lxxx. 1) He lifted up His eyes to heaven to teach us intentness in our prayers: that we should stand with uplifted eyes, not of the body only, but of the mind.
John Chrysostom · d. 407Catena Aurea (Aquinas, 1274)
(Tr. civ) Our Lord, in the form of a servant, could have prayed in silence had He pleased; but He remembered that He had not only to pray, but to teach. For not only His discourse, but His prayer also, was for His disciples' edification, yea and for ours who read the same. Father, the hour is come, shews that all time, and every thing that He did or suffered to be done, was at His disposing, Who is not subject to time. Not that we must suppose that this hour came by any fatal necessity, but rather by God's ordering. Away with the notion, that the stars could doom to death the Creator of the stars. (Tr. civ) But if He was glorified by His Passion, how much more by His Resurrection? For His Passion rather shewed His humility than His glory. So we must understand, Father, the hour is come, glorify Thy Son, to mean, the hour is come for sowing the seed, humility; defer not the fruit, glory.
Augustine of Hippo · d. 430Catena Aurea (Aquinas, 1274)
Before these words, which we are now, with the Lord's help, to make the subject of discourse, Jesus had said, "These things have I spoken unto you, that in me ye might have peace;" which we are to consider as referring, not to the later words uttered by Him immediately before, but to all that He had addressed to them, whether from the time that He began to account them disciples, or at least from the time after supper when He commenced this admirable and lengthened discourse. He gave them, indeed, such a reason for speaking to them, that either all He ever spake to them may with the utmost propriety be referred to that end, or those especially, as His last words, which He now spake when on the eve of dying for them, after that he who was to betray Him had quitted their company. For He gave this as the cause of His discourse, that in Him they might have peace, just as it is wholly on this account that we are Christians. For this peace will have no temporal end, but will itself be the end of every pious intention and action that are ours at present. For its sake we are endowed with His sacraments, for its sake we are instructed by His works and sayings, for its sake we have received the earnest of the Spirit, for its sake we believe and hope in Him, and according to His gracious giving are enkindled with His love: by this peace we are comforted in all our distresses, by it we are delivered from them all: for its sake we endure with fortitude every tribulation, that in it we may reign in happiness without any tribulation.
Augustine of Hippo · d. 430Tractates on John
Fitly therewith did He bring His words to a close, which were proverbs to the disciples, who as yet had little understanding, but would afterwards understand them, when He had given them the Holy Spirit of promise, of whom He had said before: "These things have I spoken unto you being yet present with you. But the Comforter, the Holy Ghost, whom the Father will send in my name, He shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you." Such, doubtless, was to be the hour, wherein He promised that He would no more speak unto them in proverbs, but show them openly of the Father. For these same words of His, when revealed by the Holy Spirit, were no more to be proverbs to those who had understanding. For when the Holy Spirit was speaking in their hearts, there was not to be silence on the part of the only-begotten Son, who had said that in that hour He would show them plainly of the Father, which, of course, would no longer be a proverb to them when now endowed with understanding. But even this also, how it is that both the Son of God and the Holy Spirit speak at once in the hearts of their spiritual ones, yea the Trinity itself, which is ever inseparably at work, is a word to those who have, but a proverb to those who are without, understanding.
Augustine of Hippo · d. 430Tractates on John
When, therefore, He had told them on what account He had spoken all things, namely, that in Him they might have peace while having distress in the world, and had exhorted them to be of good cheer, because He had overcome the world; having thus finished His discourse to them, He then directed His words to the Father, and began to pray. For so the evangelist proceeds to say: "These things spake Jesus, and lifted up His eyes to heaven, and said: Father, the hour is come; glorify Thy Son." The Lord, the Only-begotten and coeternal with the Father, could in the form of a servant and out of the form of a servant, if such were needful, pray in silence; but in this other way He wished to show Himself as one who prayed to the Father, that He might remember that He was still our Teacher. Accordingly, the prayer which He offered for us, He made also known to us; seeing that it is not only the delivering of discourses to them by so great a Master, but also the praying for them to the Father, that is a means of edification to disciples. And if so to those who were present to hear what was said, it is certainly so also to us who were to have the reading of it when written.
Augustine of Hippo · d. 430Tractates on John
Wherefore in saying this, "Father, the hour is come; glorify Thy Son," He showed that all time, and every occasion when He did anything or suffered anything to be done, were arranged by Him who was subject to no time: since those things, which were individually future in point of time, have their efficient causes in the wisdom of God, wherein there are no distinctions of time. Let it not, then, be supposed that this hour came through any urgency of fate, but rather by the divine appointment. It was no necessary law of the heavenly bodies that tied to its time the passion of Christ; for we may well shrink from the thought that the stars should compel their own Maker to die. It was not the time, therefore, that drove Christ to His death, but Christ who selected the time to die: who also fixed the time, when He was born of the Virgin, with the Father, of whom He was born independently of time. And in accordance with this true and salutary doctrine, the Apostle Paul also says, "But when the fullness of the time was come, God sent forth His Son;" and God declares by the prophet, "In an acceptable time have I heard Thee, and in a day of salvation have I helped thee;" and yet again the apostle, "Behold, now is the accepted time; behold, now is the day of salvation." He then may say, "Father, the hour is come," who has arranged every hour with the Father: saying, as it were, "Father, the hour," which we fixed together for the sake of men and of my glorification among them, "is come, glorify Thy Son, that Thy Son also may glorify Thee."
Augustine of Hippo · d. 430Tractates on John
The glorification of the Son by the Father is understood by some to consist in this, that He spared Him not, but delivered Him up for us all. But if we say that He was glorified by His passion, how much more was He so by His resurrection! For in His passion our attention is directed more to His humility than to His glory, in accordance with the testimony of the apostle, who says, "He humbled Himself, and became obedient unto death, even the death of the cross:" and then he goes on to say of His glorification, "Wherefore God also hath highly exalted Him, and given Him a name which is above every name: that in the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth; and that every tongue should confess that the Lord Jesus Christ is in the glory of God the Father." This is the glorification of our Lord Jesus Christ, that took its commencement from His resurrection. His humility accordingly begins in the apostle's discourse with the passage where he says, "He emptied Himself, and took upon Him the form of a servant;" and reaches "even to the death of the cross." But His glory begins with the clause where he says, "Wherefore God also hath exalted Him;" and reaches on to the words, "is in the glory of God the Father."
Augustine of Hippo · d. 430Tractates on John
In order, then, that the Mediator between God and men, the man Christ Jesus, might be made lustrous or glorious by His resurrection, He was first humbled by suffering; for had He not died, He would not have risen from the dead. Humility is the earning of glory; glory, the reward of humility. This, however, was done in the form of a servant; but He was always in the form of God, and always shall His glory continue: yea, it was not in the past as if it were no more so in the present, nor shall it be, as if it did not yet exist; but without beginning and without end, His glory is everlasting. Accordingly, when He says, "Father, the hour is come; glorify Thy Son," it is to be understood as if He said, The hour is come for sowing the seed-corn of humility, delay not the fruit of my glory.
Augustine of Hippo · d. 430Tractates on John
That the Son was glorified by the Father in His form of a servant, which the Father raised from the dead and set at His own right hand, is indicated by the event itself, and is nowhere doubted by the Christian. But as He not only said, "Father, glorify Thy Son," but likewise added, "that Thy Son may glorify Thee," it is worthy of inquiry how it was that the Son glorified the Father, seeing that the eternal glory of the Father neither suffered diminution in any human form, nor could be increased in respect of its own divine perfection. In itself, indeed, the glory of the Father could neither be diminished nor enlarged; but without any doubt it was less among men when God was known only in Judea: and as yet children praised not the name of the Lord from the rising of the sun to its going down. But inasmuch as this was effected by the gospel of Christ, to wit, that the Father became known through the Son to the Gentiles, assuredly the Son also glorified the Father. Had the Son, however, only died, and not risen again, He would without doubt have neither been glorified by the Father, nor have glorified the Father; but now having been glorified through His resurrection by the Father, He glorifies the Father by the preaching of His resurrection. For this is disclosed by the very order of the words: "Glorify," He says, "Thy Son, that Thy Son may glorify Thee;" saying, as it were, Raise me up again, that by me Thou mayest become known to all the world.
Augustine of Hippo · d. 430Tractates on John
These things spake Jesus, those things that He had said at the supper, partly sitting as far as the words, Arise, let us go hence; (c. 14:31.) and thence standing, up to the end of the hymn which now commences, And lifted up His eyes and said, Father, the hour is come; glorify Thy Son.
Bede · d. 735Catena Aurea (Aquinas, 1274)

Verse 2

(iii. de Trin) For being made flesh Himself, He was about to restore eternal life to frail, corporeal, and mortal man. (ix. de Trin. 31) If Christ be God, not begotten, but unbegotten, then let this receiving be thought weakness. But not if His receiving of power signifies His begetting, in which He received what He is. This gift cannot be counted for weakness. For the Father is such in that He gives; the Son remains God in that He hath received the power of giving eternal life.
Hilary of Poitiers · d. 367Catena Aurea (Aquinas, 1274)
"As Thou hast given Him power over all flesh." He now showeth, that what belongs to the preaching is not confined to the Jews alone, but is extended to all the world, and layeth down beforehand the first invitations to the Gentiles. And since He had said, "Go not into the way of the Gentiles" (Matt. x. 5), and after this time is about to say, "Go ye, and make disciples of all nations" (Matt. xxviii. 19), He showeth that the Father also willeth this. For this greatly offended the Jews, and the disciples too; nor indeed after this did they easily endure to lay hold on the Gentiles, until they received the teaching of the Spirit; because hence arose no small stumblingblock for the Jews.
John Chrysostom · d. 407Homilies on John
"Of all flesh"? For certainly not all believed. Yet, for His part, all believed; and if men gave no heed to His words, the fault was not in the Teacher, but in those who received them not.
John Chrysostom · d. 407Homilies on John
"That He should give eternal life to as many as Thou hast given Him." If here also He speaketh in a more human manner, wonder not. For He doth so both on account of the reasons I have given, and to avoid the saying anything great concerning Himself; since this was a stumblingblock to the hearers because as yet they imagined nothing great concerning Him.
John Chrysostom · d. 407Homilies on John
(Tr. cv) But it is justly asked, how the Son can glorify the Father, when the eternal glory of the Father never experienced abasement in the form of man, and in respect of its own Divine perfection, does not admit of being added to. But among men this glory was less when God was only known in Judæa; and therefore the Son glorified the Father, when the Gospel of Christ spread the knowledge of the Father among the Gentiles. Glorify Thy Son, that Thy Son also may glorify Thee; i. e. Raise Me from the dead, that by Me Thou mayest be known to the whole world. Then He unfolds further the manner in which the Son glorifies the Father; As Thou hast given Him power over all flesh, that He should give eternal life to as many as Thou hast given Him. All flesh signifies all mankind, the part being put for the whole. And this power which is given to Christ by the Father over all flesh, must be understood with reference to His human nature. (Tr. cv. 2) He saith, As Thou hast given Him power over all flesh, so the Son may glorify Thee, i. e. make Thee known to all flesh which Thou hast given Him; for Thou hast so given it to Him, that He should give eternal life to as many as Thou hast given Him.
Augustine of Hippo · d. 430Catena Aurea (Aquinas, 1274)
And then expanding still further how it was that the Father should be glorified by the Son, He says: "As Thou hast given Him power over all flesh, that He should give eternal life to all that Thou hast given Him." By all flesh, He meant every man, signifying the whole by a part; as, on the other hand, the whole man is signified by the superior part, when the apostle says, "Let every soul be subject to the higher powers." For what else did He mean by "every soul," save every man? And this, therefore, that power over all flesh was given to Christ by the Father, is to be understood in respect of His humanity; for in respect of His Godhead all things were made by Himself, and in Him were created all things in heaven and in earth, visible and invisible. "As," then, He says, "Thou hast given Him power over all flesh," so may Thy Son glorify Thee, in other words, make Thee known to all flesh whom Thou hast given Him. For Thou hast so given, "that He should give eternal life to all that Thou hast given Him."
Augustine of Hippo · d. 430Tractates on John

Verse 3

(iii. de Tr. c. 14) And in what eternal life is, He then shews: And this is life eternal, that they might know Thee, the only true God. To know the only true God is life, but this alone does not constitute life. What else then is added? And Jesus Christ whom Thou hast sent. (iv. de Tr. c. 9) The Arians hold, that as the Father is the only true, only just, only wise God, the Son hath no communion of these attributes; for that which is proper to one, cannot be partaken of by another. And as these are as they think in the Father alone, and not in the Son, they necessarily consider the Son a false and vain God. (v. de Tr. 3) But it must be clear to every one that the reality of any thing is evidenced by its power. For that is true wheat, which when rising with grain and fenced with ears, and shaken out by the winnowing machine, and ground into corn, and baked into bread, and taken for food, fulfils the nature and function of bread. I ask then wherein the truth of Divinity is wanting to the Son, Who hath the nature and virtue of Divinity. For He so made use of the virtue of His nature, as to cause to be things which were not, and to do every thing which seemed good to Him. (ix. de Trin) Because He says, Thee the only, does He separate Himself from communion and unity with God? He doth separate Himself, but that He adds immediately, And Jesus Christ Whom Thou hast sent. For the Catholic faith confesses Christ to be true God, in that it confesses the Father to be the only true God; for natural birth did not introduce any change of nature into the Only-Begotten God.
Hilary of Poitiers · d. 367Catena Aurea (Aquinas, 1274)
"And this is life eternal, that they might know Thee the only true God, and Jesus Christ whom Thou hast sent." "The only true God," He saith, by way of distinction from those which are not gods; for He was about to send them to the Gentiles. But if they will not allow this, but on account of this word "only" reject the Son from being true God, in this way as they proceed they reject Him from being God at all. For He also saith, "Ye seek not the glory which is from the only God." (c. v. 44.) Well then; shall not the Son be God? But if the Son be God, and the Son of the Father who is called the Only God, it is clear that He also is true, and the Son of Him who is called the Only true God.
John Chrysostom · d. 407Homilies on John
Why, when Paul saith, "Or I only and Barnabas" (1 Cor. ix. 6), doth he exclude Barnabas? Not at all; for the "only" is put by way of distinction from others. And, if He be not true God, how is He "Truth"? for truth far surpasses what is true. What shall we call the not being a "true" man, tell me? shall we not call it the not being a man at all? so if the Son is not true God, how is He God? And how maketh He us gods and sons, if He is not true?
John Chrysostom · d. 407Homilies on John
(vi. de Tr. c. 9) Dismissing then the Arians, let us see if we are forced to confess, that by the words, That they may know Thee to be the only true God, He means us to understand that the Father only is the true God, in such sense as that only the Three together, Father, Son, and Holy Ghost, are to be called God? Does our Lord's testimony authorize us to say that the Father is the only true God, the Son the only true God, and the Holy Ghost the only true God, and at the same time, that the Father, Son, and Holy Ghost together, i. e. the Trinity, are not three Gods, but one true God? (Tr. c. 5) Or is not the order of the words, That they may know Thee and Jesus Christ, Whom Thou hast sent, to be the only true God? the Holy Spirit being necessarily understood, because the Spirit is only the love of the Father and the Son, consubstantial with both. If then the Son so glorifies Thee as Thou hast given Him power over all flesh, and Thou hast given Him the power, that He should give eternal life to as many as Thou hast given Him, and, This is life eternal, to know Thee, it follows that He glorifies Thee by making Thee known to all whom Thou hast given Him. Moreover, if the knowledge of God is life eternal, the more advance we make in this knowledge, the more we make in life eternal. But in life eternal we shall never die. Where then there is no death, there will then be perfect knowledge of God; there will God be most glorified, because His glory will be greatest. Glory was defined among the ancients to be fame accompanied with praise. But if man is praised in dependence on what is said of him, how will God be praised when He shall be seen? as in the Psalm, Blessed are they who dwell in Thy house: they will be alway praising Thee. (Ps. 83:4) There will be praise of God without end, where will be full knowledge of God. There then shall be heard the everlasting praise of God, for there will there be full knowledge of God, and therefore full glorifying of Him. (i. de Trin. c. viii) What He said to His servant Moses, I am that I am; (Exod. 3) this we shall contemplate in the life eternal. (iv. de Trin. c. xviii) For when sight has made our faith truth, then eternity shall take possession of and displace our mortality.
Augustine of Hippo · d. 430Catena Aurea (Aquinas, 1274)
"And this," He adds, "is eternal life, that they may know Thee, the only true God, and Jesus Christ, whom Thou hast sent." The proper order of the words is, "That they may know Thee and Jesus Christ, whom Thou hast sent, as the only true God." Consequently, therefore, the Holy Spirit is also understood, because He is the Spirit of the Father and Son, as the substantial and consubstantial love of both. For the Father and Son are not two Gods, nor are the Father and Son and Holy Spirit three Gods; but the Trinity itself is the one only true God. And yet the Father is not the same as the Son, nor the Son the same as the Father, nor the Holy Spirit the same as the Father and the Son; for the Father and Son and Holy Spirit are three [persons], yet the Trinity itself is one God. If, then, the Son glorifies Thee in the same manner "as Thou hast given Him power over all flesh," and hast so given, "that He should give eternal life to all that Thou hast given Him," and "this is life eternal, that they may know Thee;" in this way, therefore, the Son glorifies Thee, that He makes Thee known to all whom Thou hast given Him. Accordingly, if the knowledge of God is eternal life, we are making the greater advances to life, in proportion as we are enlarging our growth in such a knowledge. And we shall not die in the life eternal; for then, when there shall be no death, the knowledge of God shall be perfected. Then will be effected the full effulgence of God, because then the completed glory. For glory, from which men are styled glorious, is thus defined: Glory is the widely-spread fame of any one accompanied with praise. But if a man is praised when the fame regarding him is believed, how will God be praised when He Himself shall be seen? Hence it is said in Scripture, "Blessed are they that dwell in Thy house; they will be praising Thee for ever and ever." There will God's praise continue without end, where there shall be the full knowledge of God; and because the full knowledge, therefore also the complete effulgence or glorification.
Augustine of Hippo · d. 430Tractates on John

Verse 4

"I have glorified Thee on the earth." Well said He, "on the earth"; for in heaven He had been already glorified, having His own natural glory, and being worshiped by the Angels. Christ then speaketh not of that glory which is bound up with His Essence, (for that glory, though none glorify Him, He ever possesseth in its fullness,) but of that which cometh from the service of men.
John Chrysostom · d. 407Homilies on John
"I have finished the work which Thou gavest Me that I should do it." And yet the action was still but beginning, or rather was not yet beginning. How then said He, "I have finished"? Either He meaneth, that "I have done all My part"; or He speaketh of the future, as having already come to pass; or, which one may say most of all, that all was already effected, because the root of blessings had been laid, which fruits would certainly and necessarily follow, and from His being present at and assisting in those things which should take place after these.
John Chrysostom · d. 407Homilies on John
But God is first of all glorified here, while He is being made known to men by word of mouth, and preached through the faith of believers. Wherefore, He says, "I have glorified Thee on the earth: I have finished the work which Thou gavest me to do." He does not say, Thou orderedst; but, "Thou gavest:" where the evident grace of it is commended to notice. For what has the human nature even in the Only-begotten, that it has not received? Did it not receive this, that it should do no evil, but all good things, when it was assumed into the unity of His person by the Word, by whom all things were made? But how has He finished the work which was committed unto Him to do, when there still remains the trial of the passion wherein He especially furnished His martyrs with the example they were to follow, whereof, says the apostle Peter, "Christ suffered for us, leaving us an example, that we should follow His steps:" but just that He says He has finished, what He knew with perfect certainty that He would finish? Just as long before, in prophecy, He used words in the past tense, when what He said was to take place very many years afterwards: "They pierced," He says, "my hands and my feet, they counted all my bones;" He says not, They will pierce, and, They will count. And in this very Gospel He says, "All things that I have heard of my Father, I have made known unto you;" to whom He afterward declares, "I have yet many things to say unto you, but ye cannot bear them now." For He, who has predestinated all that is to be by sure and unchangeable causes, has done whatever He is to do: as it was also declared of Him by the prophet, "Who hath made the things that are to be."
Augustine of Hippo · d. 430Tractates on John

Verse 4–5

(iii. de Trin) This new glory with which our Lord had glorified the Father, does not imply any advancement in Godhead, but refers to the honour received from those who are converted from ignorance to knowledge. (ix. de Trin) After which, that we may understand the reward of His obedience, and the mystery of the whole dispensation, He adds, And now glorify Me with the glory with Thine own Self, with the glory which I had with Thee before the world was. (iii. de Trin) Or He prayed that that which was mortal, might receive the glory immortal, that the corruption of the flesh might be transformed and absorbed into the incorruption of the Spirit.
Hilary of Poitiers · d. 367Catena Aurea (Aquinas, 1274)
(Tr. cv) But God is first glorified here, when He is proclaimed, made known to, and believed in, by men: I have glorified Thee on the earth. (Tr. cv) Not Thou commandest Me, but, Thou gavest Me, implying evidently grace. For what hath human nature, even in the Only-Begotten, what it hath not received? But how had He finished the work which had been given Him to do, when there yet remained His passion to undergo? He says He has finished it, i. e. He knows for certain that He will. (Tr. cv. 5) He had said above, Father, the hour is come; glorify Thy Son, that Thy Son also may glorify Thee: the order of which words shows that the Son was first to be glorified by the Father, that the Father might be glorified by the Son. But now He says, I have glorified Thee; and now glorify Me; as if He had first glorified the Father, and then asked to be glorified by Him. We must understand that the first is the order in which one was to succeed the other, but that He afterwards uses a past tense, to express a thing future; the meaning being, I will glorify Thee on the earth, by finishing the work Thou hast given Me to do: and now, Father, glorify Me, which is quite the same sentence with the first one, except that He adds here the mode in which He is to be glorified; with the glory which I had before the world was, with Thee. The order of the words is, The glory which I had with Thee before the world was. This has been taken by some to mean, that the human nature which was assumed by the Word, would be changed into the Word, that man would be changed into God, or, to speak more correctly, be lost in God. For no one would say that the Word of God would by that change be doubled, or even made at all greater. But we avoid this error, if we take the glory which He had with the Father before the world was, to be the glory which He predestined for Him on earth: (for if we believe Him to be the Son of man, we need not be afraid to say that He was predestinated.) This predestined time of His being glorified, He now saw was arrived, that He might now receive what had been aforetime predestined, He prayed accordingly: And now, Father, glorify Me, &c. i. e. that glory which I had with Thee by Thy predestination, it is now time that I should have at Thy right hand.
Augustine of Hippo · d. 430Catena Aurea (Aquinas, 1274)
In a way similar, also, to this, He proceeds to say: "And now, O Father, glorify thou me with Thine own self with the glory which I had with Thee before the world was." For He had said above, "Father, the hour is come; glorify Thy Son, that Thy Son may glorify Thee:" in which arrangement of the words He had shown that the Father was first to be glorified by the Son, in order that the Son might glorify the Father. But now He said, "I have glorified Thee on the earth: I have finished the work which Thou gavest me to do; and now glorify Thou me;" as if He Himself had been the first to glorify the Father, by whom He then demands to be glorified. We are therefore to understand that He used both words above in accordance with that which was future, and in the order in which they were future, "Glorify Thy Son, that Thy Son may glorify Thee:" but that He now used the word in the past tense of that which was still future, when He said, "I have glorified Thee on the earth: I have finished the work which Thou gavest me to do." And then, when He said, "And now, O Father, glorify Thou me with Thine own self," as if He were afterwards to be glorified by the Father, whom He Himself had first glorified; what did He intimate but that, when He said above, "I have glorified Thee on the earth," He had so spoken as if He had done what He was still to do; but that here He demanded of the Father to do that whereby the Son should yet do so; in other words, that the Father should glorify the Son, by means of which glorification of the Son, the Son also was yet to glorify the Father?
Augustine of Hippo · d. 430Tractates on John

Verse 5

"And now, O Father, glorify Thou Me with Thine Own Self, with the glory which I had with Thee before the world was." Where is that glory? For allowing that He was with reason unhonored among men, because of the covering which was put around Him; how seeketh He to be glorified with the Father? What then saith He here? The saying refers to the Dispensation; since His fleshly nature had not yet been glorified, not having as yet enjoyed incorruption, nor shared the kingly throne. Therefore He said not "on earth," but "with Thee."
John Chrysostom · d. 407Homilies on John
But this predestination He still more clearly disclosed in respect of His own glorification, wherewith He was glorified by the Father, when He added, "With the glory which I had, before the world was, with Thee." The proper order of the words is, "which I had with Thee before the world was." To this apply His words, "And now glorify Thou me;" that is to say, as then, so also now: as then, by predestination; so also now, by consummation: do Thou in the world what had already been done with Thee before the world: do in its own time what Thou hast determined before all times. This, some have imagined, should be so understood as if the human nature, which was assumed by the Word, were converted into the Word, and the man were changed into God; yea, were we reflecting with some care on the opinions they have advanced, as if the humanity were lost in the Godhead. For no one would go the length of saying that out of such a transmutation of the humanity the Word of God is either doubled or increased, so that either what was one should now be two, or what was less should now be greater. Accordingly, if with His human nature changed and converted into the Word, the Word of God will still be as great as He was, and what He was, where is the humanity, if it is not lost? But to this opinion, which I certainly do not see to be conformable to the truth, there is nothing to urge us, if, when the Son says, "And now, O Father, glorify Thou me with Thine own self, with the glory which I had with Thee before the world was," we understand the predestination of the glory of His human nature, as thereafter, from being mortal, to become immortal with the Father: and that this had already been done by predestination before the world was, as also in its own time it was done in the world. For if the apostle has said of us, "According as He hath chosen us in Him before the foundation of the world," why should it be thought incongruous with the truth, if the Father glorified our Head at the same time as He chose us in Him to be His members? For we were chosen in the same way as He was glorified; inasmuch as before the world was, neither we nor the Mediator between God and men, the man Christ Jesus, were yet in existence.
Augustine of Hippo · d. 430Tractates on John
But perhaps we shall have some fear in saying that He was predestinated, because the apostle seems to have said so only in reference to our being made conformable to His image. As if, indeed, any one, faithfully considering the rule of faith, were to deny that the Son of God was predestinated, who yet cannot deny that He was man. For it is rightly said that He was not predestinated in respect of His being the Word of God, God with God. For how could He be predestinated, seeing He already was what He was, without beginning and without ending, everlasting? But that, which as yet was not, had to be predestinated, in order that it might come to pass in its time, even as it was predestinated so to come before all times. Accordingly, whoever denies predestination of the Son of God, denies that He was also Himself the Son of man. But, on account of those who are disputatious, let us also on this subject listen to the apostle in the exordium of his epistles. For both in the first of his epistles, which is that to the Romans, and in the beginning of the epistle itself, we read: "Paul, a servant of Jesus Christ, called [to be] an apostle, separated unto the gospel of God, which He had promised afore by His prophets in the Holy Scriptures, concerning His Son, who was made for Him of the seed of David according to the flesh, who was predestinated the Son of God in power, according to the Spirit of holiness, by the resurrection from the dead." In respect, then, of this predestination also, He was glorified before the world was, in order that His glory might be, by the resurrection from the dead, with the Father, at whose right hand He sitteth. Accordingly, when He saw that the time of this, His predestinated glorification, was now come, in order that what had already been done in predestination might also be done now in actual accomplishment, He said in His prayer, "And now, O Father, glorify Thou me with Thine own self with the glory which I had with Thee before the world was:" as if He had said, The glory which I had with Thee, that is, that glory which I had with Thee in Thy predestination, it is time that I should have with Thee also in sitting at Thy right hand.
Augustine of Hippo · d. 430Tractates on John

Verse 6

"Messenger of great counsel" (Isa. ix. 6, LXX.), the Son of God is called, because of the other things which He taught, and principally because He announced the Father to men, as also now He saith, "I have manifested Thy Name unto the men." For after having said, "I have finished Thy work," He next explaineth it in detail, telling what sort of work. Now the Name indeed was well known. For Esaias said, "Ye shall swear by the true God." (Isa. lxv. 16.) But what I have often told you I tell you now, that though it was known, yet it was so only to Jews, and not to all of these: but now He speaketh concerning the Gentiles. Nor doth He declare this merely, but also that they knew Him as the Father. For it is not the same thing to learn that He is Creator, and that He hath a Son. But He "manifested His Name" both by words and actions. "Whom Thou gavest Me out of the world." As He saith above, "No man cometh unto Me except it be given him" (c. vi. 65); and, "Except My Father draw him" (c. vi. 64); so here too, "Whom thou gavest Me." (c. xiv. 6.) Now He calleth Himself "the Way"; whence it is clear that He establisheth two things by what is said here, that He is not opposed to the Father, and that it is the Father's will to entrust them to the Son. "Thine they were, and Thou gavest them Me." Here He desireth to teach that He is greatly loved by the Father. For that He needed not to receive them, is clear from this, He made them, He careth for them continually. How then did He receive them? This, as I said before, showeth His unanimity with the Father. Now if a man choose to enquire into the matter in a human manner, and as the words are spoken, they will no longer belong to the Father. For if when the Father had them, the Son had them not, it is evident that when He gave them to the Son, He withdrew from His dominion over them. And again, there is a yet more unseemly conclusion; for they will be found to have been imperfect while they yet were with the Father, but to have become perfect when they came to the Son. But it is mockery even to speak thus. What then doth He declare by this? "That it hath seemed good to the Father also that they should believe on the Son."
John Chrysostom · d. 407Homilies on John
(Tr. cvi) If He speaks of the disciples only with whom He supped, this has nothing to do with that glorifying of which He spoke above, wherewith the Son glorified the Father; for what glory is it to be known to twelve or eleven men? But if by the men which were given to Him out of the world, He means all those who should believe in Him afterwards, this is without doubt the glory wherewith the Son glorifies the Father; and, I have manifested Thy name, is the same as what He said before, I have glorified Thee; the past being put for the future both there and here. But what follows shows that He is speaking here of those who were already His disciples, not of all who should afterwards believe on Him. At the beginning of His prayer then our Lord is speaking of all believers, all to whom He should make known the Father, thereby glorifying Him: for after saying, that Thy Son also may glorify Thee, in showing how that was to be done, He says, As Thou hast given Him power over all flesh. Now let us hear what He says to the disciples: I have manifested Thy name to the men which Thou gavest Me out of the world. Had they not known the name of God then, when they were Jews? We read in the Psalms, In Jewry is God known; His name is great in Israel. (Ps. 76:1) I have manifested Thy name, then, must be understood not of the name of God, but of the Father's name, which name could not be manifested without the manifestation of the Son. For God's name, as the God of the whole creation, could not have been entirely unknown to any nation. As the Maker then of the world, He was known among all nations, even before the spread of the Gospel. In Jewry He was known as a God, Who was not to be worshipped with the false gods: but as the Father of that Christ, by whom He took away the sins of the world, His name was unknown; which name Christ now manifesteth to those whom the Father had given Him out of the world. But how did He manifest it, when the hour had not come of which He said above, The hour cometh, when I shall no more speak unto you in proverbs. We must understand the past to be put for the future. (Tr. cvi) Which Thou hast given Me out of the world: i. e. who were not of the world. But this they were by regeneration, not by nature. What is meant by, Thine they were, and Thou gavest them Me? Had ever the Father any thing without the Son? God forbid. But the Son of God had that sometimes, which He had not as Son of man; for He had the universe with His Father, while He was still in His mother's womb. Wherefore by saying, They were Thine, the Son of God does not separate Himself from the Father; but only attributes all His power to Him, from whom He is, and hath the same. And Thou gavest them Me, then, means that He had received as man the power to have them; nay, that He Himself had given them to Himself, i. e. Christ as God with the Father, to Christ as man not with the Father. His purpose here is to show His unanimity with the Father, and how that it was the Father's pleasure that they should believe in Him. (Tr. cvi) The Father gave Him all things, when having all things He begat Him. (Tr. cvi. c. 6) i. e. have understood and remembered them. For then is a word received, when the mind apprehends it; as it follows, And have known surely that I came out from Thee. And that none might imagine that that knowledge was one of sight, not of faith, He adds, And they hare believed (surely, is understood) that Thou didst send Me. What they believed surely, was what they knew surely; for, I came out from Thee, is the same with, Thou didst send Me. They believed surely, i. e. not as He said above they believed, but surely, i. e. as they were about to believe firmly, steadily, unwaveringly: never any more to be scattered to their own, and leave Christ. The disciples as yet were not such as He describes them to be in the past tense, meaning such as they were to be when they had received the Holy Ghost. The question how the Father gave those words to the S
Augustine of Hippo · d. 430Catena Aurea (Aquinas, 1274)
In this discourse we purpose speaking, as He gives us grace, on these words of the Lord which run thus: "I have manifested Thy name unto the men whom Thou gavest me out of the world." If He said this only of those disciples with whom He had supped, and to whom, before beginning His prayer, He had said so much, it can have nothing to do with that clarification, or, as others have translated it, glorification, whereof He was previously speaking, and whereby the Son clarifies or glorifies the Father. For what great glory, or what like glory, was it to become known to twelve, or rather eleven mortal creatures? But if, in saying, "I have manifested Thy name unto the men whom Thou gavest me out of the world," He wished all to be understood, even those who were still to believe on Him, as belonging to His great Church which was yet to be made up of all nations, and of which it is said in the psalm, "I will confess to Thee in the great Church [congregation];" it is plainly that glorification wherewith the Son glorifies the Father, when He makes His name known to all nations and to so many generations of men. And what He says here, "I have manifested Thy name unto the men whom Thou gavest me out of the world," is similar to what He had said a little before, "I have glorified Thee upon the earth"; putting both here and there the past for the future, as One who knew that it was predestinated to be done, and therefore saying that He had done what He had still to do, though without any uncertainty, in the future.
Augustine of Hippo · d. 430Tractates on John
But what follows makes it more credible that His words, "I have manifested Thy name to the men whom Thou gavest me out of the world," were spoken by Him of those who were already His disciples, and not of all who were yet to believe on Him. For after these words, He added: "Thine they were, and Thou gavest them me; and they have kept Thy word. Now they have known that all things, whatsoever Thou hast given me, are of Thee: for I have given unto them the words which Thou gavest me; and they have received them, and have known surely that I came out from Thee, and they have believed that Thou didst send me." Although all these words also might have been said of all believers still to come, when that which was now a matter of hope had been turned into fact, inasmuch as they were words that still pointed to the future; yet we are impelled the more to understand Him as uttering them only of those who were at that time His disciples, by what He says shortly afterwards: "While I was with them, I kept them in Thy name: those that Thou gavest me I have kept, and none of them is lost, but the son of perdition; that the Scripture might be fulfilled"; meaning Judas, who betrayed Him, for He was the only one of the apostolic twelve that perished.
Augustine of Hippo · d. 430Tractates on John
Accordingly, let us now see what He says about those disciples of His who were then listening to Him. "I have manifested," He says. "Thy name unto the men whom Thou gavest me." Did they not, then, know the name of God when they were Jews? And what of that which we read, "God is known in Judah; His name is great in Israel"? Therefore, "I have manifested Thy name unto these men whom Thou gavest me out of the world," and who are now hearing my words: not that name of Thine whereby Thou art called God, but that whereby Thou art called my Father: a name that could not be manifested without the manifestation of the Son Himself. For this name of God, by which He is called, could not but be known in some way to the whole creation, and so to every nation, before they believed in Christ. For such is the energy of true Godhead, that it cannot be altogether and utterly hidden from any rational creature, so long as it makes use of its reason. For, with the exception of a few in whom nature has become outrageously depraved, the whole race of man acknowledges God as the maker of this world. In respect, therefore, of His being the maker of this world that is visible in heaven and earth around us, God was known unto all nations even before they were indoctrinated into the faith of Christ. But in this respect, that He was not, without grievous wrong being done to Himself, to be worshipped alongside of false gods, God was known in Judah alone. But in respect of His being the Father of this Christ, by whom He taketh away the sin of the world, this name of His, previously kept secret from all, He now made manifest to those whom the Father Himself had given Him out of the world.
Augustine of Hippo · d. 430Tractates on John
But what are we to make of the words. "Whom Thou gavest me out of the world"? For it is said of them that they were not of the world. But this they attained to by regeneration, and not by generation. And what, also, of that which follows, "Thine they were, and Thou gavest them me"? Was there a time when they belonged to the Father, and not to His only-begotten Son; and had the Father once on a time anything apart from the Son? Surely not. Nevertheless, there was a time when God the Son had something, which that same Son as man possessed not; for He had not yet become man of an earthly mother, when He possessed all things in common with the Father. Wherefore in saying, "Thine they were," there is thereby no self-disruption made by God the Son, apart from whom there was nothing ever possessed by the Father; but it is His custom to attribute all the power He possesses to Him, of whom He Himself is, who has the power. For of whom He has it that He is, of Him He has it that He is able; and both together He always had, for He never had being without having ability. Accordingly, whatever the Father could [do], always side by side with Him could the Son; since He, who never had being without having ability, was never without the Father, as the Father never was without Him. And thus, as the Father is eternally omnipotent, so is the Son co-eternally omnipotent; and if all-powerful, certainly all-possessing.
Augustine of Hippo · d. 430Tractates on John

Verse 6–7

And they have kept Thy word. He calls Himself the Word of the Father, because the Father by Him created all things, and because He contains in Himself all words: as if to say, They have committed Me to memory so well, that they never will forget Me. Or, They have kept Thy word, i. e. in that they have believed in Me: as it follows, Now they have known that all things whatsoever Thou hast given Me, are of Thee. Some read, Now I have known, &c. But this cannot be correct. For how could the Son be ignorant of what was the Father's? It is the disciples He is speaking of; as if to say, They have learnt that there is nothing in Me alien from Thee, and that whatever I teach cometh from Thee.
Bede · d. 735Catena Aurea (Aquinas, 1274)

Verse 7–8

"And they have kept Thy word." "Now they have known that all things whatsoever Thou hast given Me are of Thee." How did they "keep Thy word"? "By believing in Me, and giving no heed to the Jews. For he that believeth in Him, it saith, 'hath set to his seal that God is true.'" (c. iii. 33.) Some read, "Now I know that all things whatsoever Thou hast given Me are of Thee." But this would have no reason; for how would the Son be ignorant of the things of the Father? No the words are spoken of the disciples. "From the time," He saith, "that I told them these things, they have learnt that all that Thou hast given Me is from Thee; nothing is alien, nothing peculiar to Me, with Thee." "They therefore have known that all things, whatsoever I teach, are Thy doctrines and teachings." "And whence have they learnt it?" From My words; for so have I taught them. And not only this have I taught them, but also that "I came out from Thee." For this He was anxious to prove through all the Gospel.
John Chrysostom · d. 407Homilies on John
He proceeds to say, "And they have kept Thy word: now they have known that all things, whatsoever Thou hast given me, are of Thee;" that is, they have known that I am of Thee. For the Father gave all things at the very time when He begat Him who was to have all things. "For I have given unto them," He says, "the words which Thou gavest me; and they have received them;" that is, they have understood and kept hold of them. For the word is received when it is perceived by the mind. "And they have known truly," He adds, "that I came out from Thee, and they have believed that Thou didst send me." In this last clause we must also supply "truly;" for when He said, "They have known truly," He intended its explanation by adding, "and they have believed." That, therefore, "they have believed truly" which "they have known truly;" just as "I came out from Thee" is the same as "Thou didst send me." When, therefore, He said, "They have known truly," lest any might suppose that such a knowledge was already acquired by sight, and not by faith, He subjoined the explanation, "And they have believed," so that we should supply "truly," and understand the saying, "They have known truly," as equivalent to "They have believed truly:" not in the way which He intimated shortly before, when He said, "Do ye now believe? The hour cometh, and is now come, that ye shall be scattered, every man to his own, and shall leave me alone." But "they have believed truly," that is, in the way it ought to be believed, without constraint, with firmness, constancy, and fortitude: no longer now to go to their own, and leave Christ alone. As yet, indeed, the disciples were not of the character He here describes in words of the past tense, as if they were so already, but as thereby declaring beforehand what sort they were yet to be, namely, when they had received the Holy Spirit, who, according to the promise, should teach them all things. For how was it, before they received the Spirit, that they kept that word of His which He spake regarding them, as if they had done so, when the chief of them thrice denied Him, after hearing from His lips the future fate of the man who denied Him before men? He had given them, therefore, as He said, the words which the Father gave Him; but when at length they received them spiritually, not in an outward way with their ears, but inwardly in their hearts, then they truly received them, for then they truly knew them; and they truly knew them, because they truly believed.
Augustine of Hippo · d. 430Tractates on John

Verse 8

But what human language will suffice to explain how the Father gave those words to the Son? The question, of course, will appear easier if we suppose Him to have received such words in His capacity as the Son of man. And yet, although thus born of the Virgin, who will undertake to relate when and how it was that He learned them, since even that very generation which He had of the Virgin who will venture to declare? But if our idea be that He received these words of the Father in His capacity as begotten of, and co-eternal with, the Father, let us then exclude all such thoughts of time as if He existed previous to His possessing them, and so received the possession of that which He had not before; for whatever God the Father gave to God the Son, He gave in the act of begetting. For the Father gave those things to the Son without which He could not be the Son, in the same manner as He gave Him being itself. For how otherwise would He give any words to the Word, wherein in an ineffable way He hath spoken all things?
Augustine of Hippo · d. 430Tractates on John

Verse 9

"I pray for them." "What sayest Thou?" "Dost Thou teach the Father, as though He were ignorant? Dost Thou speak to Him as to a man who knoweth not?" "What then meaneth this distinction?" Seest thou that the prayer is for nothing else than that they may understand the love which He hath towards them? For He who not only giveth what He hath of His own, but also calleth on Another to do the same, showeth greater love. What then is, "I pray for them"? "Not for all the world," He saith, but "for them whom Thou hast given Me." He continually putteth the "hast given," that they might learn that this seemeth good to the Father. Then, because He had said continually, "they are Thine," and, "Thou gavest them unto Me," to remove any evil suspicion, and lest any one should think that His authority was recent, and that He had but now received them, what saith He?
John Chrysostom · d. 407Homilies on John
(Tr. cvi) When He adds, I pray not for the world, by the world He means those who live according to the lust of the world, and have not the lot to be chosen by grace out of the world, as those had for whom He prayed: But for them which Thou hast given Me. It was because the Father had given Him them, that they did not belong to the world. Nor yet had the Father, in giving them to the Son, lost what He had given: For they are Thine.
Augustine of Hippo · d. 430Catena Aurea (Aquinas, 1274)

Verse 9–10

When the Lord was speaking to the Father of those whom He already had as disciples, He said this also among other things: "I pray for them. I pray not for the world, but for those whom Thou hast given me." By the world, He now wishes to be understood those who live according to the lust of the word, and stand not in the gracious lot of such as were to be chosen by Him out of the world. Accordingly it is not for the world, but for those whom the Father hath given Him, that He expresses Himself as praying: for by the very fact of their having already been given Him by the Father, they have ceased to belong to that world for which He refrains from praying. And then He adds, "For they are Thine." For the Father did not lose those whom He gave, in the act of giving them to the Son; since the Son still goes on to say, "And all mine are Thine, and Thine are mine." Where it is sufficiently apparent how it is that all that belongs to the Father belongs also to the Son; in this way, namely, that He Himself is also God, and, of the Father born, is the Father's equal: and not as was said to one of the two sons, to wit, the elder, "Thou art ever with me; and all that I have is thine." For that was said of all those creatures which are inferior to the holy rational creature, and are certainly subordinate to the Church; wherein its universal character is understood as including those two sons, the elder and the younger, along with all the holy angels, whose equals we shall be in the kingdom of Christ and of God: but here it was said, "And all mine are Thine, and Thine are mine," with this meaning, that even the rational creature is itself included, which is subject only to God, so that all beneath it are also subject to Him. As it then belongs to God the Father, it would not at the same time be the Son's likewise, were He not equal to the Father: for to it He was referring when He said, "I pray not for the world, but for those whom Thou hast given me: for they are Thine, and all mine are Thine, and Thine are mine." Nor is it morally admissible that the saints, of whom He so spake, should belong to any save to Him by whom they were created and sanctified: and for the same reason, everything also that is theirs must of necessity be His also to whom they themselves belong, Accordingly, since they belong both to the Father and to the Son, they demonstrate the equality of those to whom they equally belong.
Augustine of Hippo · d. 430Tractates on John

Verse 10

"All Mine are Thine, and Thine are Mine; and I am glorified in them." Seest thou the equality of honor? For lest on hearing, "Thou hast given them Me," thou shouldest deem that they were alienated from the authority of the Father, or before this from that of the Son, He removed both difficulties by speaking as He did. It was as though He said, "Do not when thou hearest that 'Thou hast given them to Me,' deem that they are alienated from the Father, for what is Mine is His; nor when thou hearest, 'Thine they were,' think that they were aliens from Me, for what is His is Mine." So that the, "Thou hast given," is said only for condescension; for what the Father hath is the Son's, and what the Son hath is the Father's. But this cannot even be said of a son after the manner of man, but because They are upon a greater Equality of honor. For that what belongs to the less, belongs to the greater also, is clear to every one, but the reverse not so; but here He converteth these terms, and the conversion declares Equality. And in another place, declaring this, He said, "All things that the Father hath are Mine," speaking of knowledge. And the "hast given Me," and the like expressions, are to show that He did not come as an alien and draw them to Him, but received them as His own. Then He putteth the cause and the proof, saying, "And I am glorified in them," that is, either that "I have power over them," or, that "they shall glorify Me, believing in Thee and Me, and shall glorify Us alike." But if He is not glorified equally in them, what is the Father's is no longer His. For no one is glorified in those over whom he hath no authority. Yet how is He glorified equally? All die for Him equally as for the Father; they preach Him as they do the Father; and as they say that all things are done in His Name, so also in the Name of the Son.
John Chrysostom · d. 407Homilies on John
(Tr. cvi. 6) It is sufficiently apparent from hence, that all things which the Father hath, the Only-Begotten Son hath; hath in that He is God, born from the Father, and equal with the Father; not in the sense in which the elder son is told, All that I have is thine. (Luke 15:31) For all there means all creatures below the holy rational creature, but here it means the very rational creature itself, which is only subjected to God. Since this is God the Father's, it could not at the same time be God the Son's, unless the Son were equal to the Father. For it is impossible that saints, of whom this is said, should be the property of any one, except Him who created and sanctified them. When He says above in speaking of the Holy Spirit, All things that the Father hath are Mine, (c. 16:15) He means all things which pertain to the divinity of the Father; for He adds, He (the Holy Ghost) shall receive of Mine; and the Holy Ghost would not receive from a creature which was subject to the Father and the Son. (Tr. cvii. 3) He speaks of this as already done, meaning that it was predestined, and sure to be. But is this the glorifying of which He speaks above, And now, O Father, glorify Thou Me with Thine own Self? If then with Thyself, what meaneth here, In them? Perhaps that this very thing, i. e. His glory with the Father, was made known to them, and through them to all that believe.
Augustine of Hippo · d. 430Catena Aurea (Aquinas, 1274)
But when He says, speaking of the Holy Ghost, "All things that the Father hath are mine; therefore said I, that He shall take of mine, and shall show it unto you," He referred to those things which concern the actual deity of the Father, and in which He is equal to Him, in having all that He has. And no more was it of the creature, which is subject to the Father and the Son, that the Holy Spirit was to receive that whereof He said, "He shall receive of mine;" but most certainly of the Father, from whom the Spirit proceedeth, and of whom also the Son is born. He proceeds: "And I am glorified in them." He now speaks of His glorification as already accomplished, although it was still future; while a little before He was demanding of the Father its accomplishment. But whether this be the same glorification, whereof He had said, "And now, O Father, glorify Thou me with Thine own self with the glory which I had with Thee before the world was," is certainly a point worthy of examination. For if "with Thee," how can it be "in them"? Is it when this very knowledge is imparted to them, and, through them, to all who believe them as His witnesses? In such a way we may clearly understand Christ as having said of the apostles, that He was glorified in them; for in saying that it was already accomplished, He showed that it was already foreordained, and only wished what was future to be regarded as certain.
Augustine of Hippo · d. 430Tractates on John

Verse 11

"And now I am no more in the world, but these are in the world." That is, "Although I appear no longer in the flesh, yet by these am I glorified." But why doth He say continuously, that, "I am not in the world"; and that, "because I leave them I commit them to Thee"; and that, "when I was in the world I kept them"? for if one should take these words in their simple sense, many absurdities will follow. For how could it be reasonable to say, that He is no longer in the world, and that when He departeth He committeth them to another? since these are the words of a mere man parting from them forever. Seest thou how He speaketh for the most part like a man, and in a way adapted to their state of mind, because they thought that they had a greater degree of safety from His presence? Wherefore He saith, "While I was with them, I kept them." (c. xiv.28.) Yet He telleth them, "I come to you"; and, "I am with you till the end." (Matt. xxviii. 20.) How then saith He these words, as if about to be parted from them? He addresseth Himself, as I said before, to their thoughts, that they may take breath a little when they hear Him speaking thus, and delivering them over to the care of the Father. For since, after hearing many exhortations from Him, they were not persuaded, He then holdeth converse with the Father, manifesting His affection for them. As though He had said, "Since Thou callest Me to Thyself, place these in safety; for I come to Thee." "What sayest Thou? Art Thou not able to keep them?" "Yea, I am able." "Wherefore then speakest Thou thus?" "That they may have My joy fulfilled" (ver. 13); that is, "may not be confounded, as being imperfect." And by these words He showed that He had spoken all these things so, to give them rest and joy. For the saying appears to be contradictory. "Now I am no longer in the world, and these are in the world." This was what they were suspecting. For a while therefore He condescendeth to them, because had He said, "I keep them," they would not have so well believed; wherefore He saith, "Holy Father, keep them through Thine own Name"; that is, "by thy help."
John Chrysostom · d. 407Homilies on John
(Tr. cvii. 4) At the time at which He was speaking, both were still in the world. Yet we must not understand, I am no more in the world, metaphorically of the heart and life; for could there ever have been a time when He loved the things of the world? It remains then that He means that He was not in the world, as He had been before; i. e. that He was soon going away. Do we not say every day, when any one is going to leave us, or going to die, such an one is gone? This is shewn to be the sense by what follows; for He adds, And now I come to Thee. And then He commends to His Father those whom He was about to leave: Holy Father, keep through Thine own name those whom Thou hast given Me. As man He prays God for His disciples, whom He received from God. But mark what follows: That they may be one, as We are: He does not say, That they may be one with Us, as We are one; but, that they may be one: that they may be one in their nature, as We are one in Ours. For, in that He was God and man in one person, as man He prayed, as God He was one with Him to Whom He prayed. (iv. de Trin. c. ix) He does not say, That I and they maybe one, though He might have said so in the sense, that He was the head of the Church, and the Church His body; not one thing, but one person: the head and the body being one Christ. But shewing something else, viz. that His divinity is consubstantial with the Father, He prays that His people may in like manner be one; but one in Christ, not only by the same nature, in which mortal man is made equal to the Angels, but also by the same will, agreeing most entirely in the same mind, and melted into one Spirit by the fire of love. This is the meaning of, That they may be one as We are: viz. that as the Father and the Son are one not only by equality of substance, but also in will, so they, between whom and God the Son is Mediator, may be one not only by the union of nature, but by the union of love.
Augustine of Hippo · d. 430Catena Aurea (Aquinas, 1274)
"And now," He adds, "I am no more in the world, and these are in the world." If your thoughts turn to the very hour in which He was speaking, both were still in the world; to wit, He Himself, and those of whom He was so speaking: for it is not in respect of the tendency of heart and life that we can or ought to understand it, so that they should be described as still in the world, on the ground that they still savored of the earthly; and that He was no longer in the world, because divine in the disposition of His mind. For there is one word used here, which makes any such understanding altogether inadmissible; because He does not say, And I am not in the world; but, "I am no more in the world:" thereby showing that He Himself had been in the world, but was no more so. And are we then at liberty to believe that He at one time savored of the worldly, and, delivered at length from such a mistake, no longer retained the old disposition? Who would venture to shut himself up in so profane a meaning. It remains, therefore, that in the same sense in which He Himself also was previously in the world, He declared that He was no longer in the world, that is to say, in His bodily presence; in other words, showing thereby that His own absence from the world was now in the immediate future, and theirs later, when He said that He was no longer here, and that they were so, although both He and they were still present. For He thus spake, as a man in harmony with men, in accordance with the prevailing custom of human speech. Do we not say every day, he is no longer here, of one who is on the very point of departure? And such in particular is the way we are wont to speak of those who are at the point of death. And besides all else, the Lord Himself, as if foreseeing the thoughts that might possibly be excited in those who were afterwards to read these words, added, "And I come to Thee:" explaining thereby in some measure why He said, "I am no more in the world."
Augustine of Hippo · d. 430Tractates on John
Accordingly He commends to the Father's care those whom He was about to leave by His bodily absence, saying: "Holy Father, keep through Thine own name those whom Thou hast given me." That is to say, as man He prays to God in behalf of His disciples, whom He has received from God. But attend to what follows: "That they may be one," He says, "even as we." He does not say, That they may be one with us, or, that they and we may be one, as we are one; but He says, "That they may be one, even as we:" meaning, of course, that in their nature they may be one, even as we are one in ours. Which certainly would not be spoken with truth, unless in this respect, that He, as God, is of the same nature as the Father also, in accordance with what He has said elsewhere, "I and the Father are one;" and not with what He also is as man, for in this respect He said, "The Father is greater than I." But since one and the same person is God and man, we are to understand the manhood in respect of His asking; but the Godhead, in as far as He Himself, and He whom He asks, are one.
Augustine of Hippo · d. 430Tractates on John

Verse 12

"While I was with them in the world, I kept them in Thy Name." Again He speaketh as a man and as a Prophet, since nowhere doth He appear to have done anything by the Name of God.
John Chrysostom · d. 407Homilies on John
"Those that Thou gavest Me I have kept, and none of them is lost, but the son of perdition, that the Scripture might be fulfilled." And in another place He saith, "Of all that Thou gavest Me, I will surely lose nothing." (c. vi. 39.) Yet not only was he lost, but also many afterwards; how then saith He, "I will in nowise lose"? "For My part, I will not lose." So in another place, declaring the matter was more clearly, He said, "I will in nowise cast out." (c. vi. 37.) "Not through fault of Mine, not because I either instigate or abandon them; but if they start away of themselves, I draw them not by necessity."
John Chrysostom · d. 407Homilies on John
But after having said that "none of them was lost but the son of perdition," He added, "that the Scripture might be fulfilled." Of what Scripture doth He speak? That which foretelleth many things concerning Him. Not that He perished on that account, in order that the Scripture might be fulfilled. But we have before spoken at length on this point, that this is the peculiar manner of Scripture, which puts things which fall out in accordance with it, as though they were caused by it. And it is needful to enquire exactly into all, both the manner of the speaker, his argument, and the laws of Scripture, if at least we are minded not to draw wrong conclusions. For, "Brethren, be not children in your minds." (1 Cor. xiv. 20.)
John Chrysostom · d. 407Homilies on John
(Tr. cvii. 6) The Son as man kept His disciples in the Father's name, being placed among them in human form: the Father again kept them in the Son's name, in that He heard those who asked in the Son's name. But we must not take this carnally, as if the Father and Son kept us in turns, for the Father, Son, and Holy Ghost guard us at the same time: but Scripture does not raise us, except it stoop to us. Let us understand then that when our Lord says this, He is distinguishing the persons, not dividing the nature, so that when the Son was keeping His disciples by His bodily presence, the Father was waiting to succeed Him on His departure; but both kept them by spiritual power, and when the Son withdrew His bodily presence, He still held with the Father the spiritual keeping. For when the Son as man received them into His keeping, He did not take them from the Father's keeping, and when the Father gave them into the Son's keeping, it was to the Son as man, who at the same time was God. Those that Thou gavest Me I have kept, and none of them is lost but the son of perdition; i. e. the betrayer of Christ, predestined to perdition; that the Scripture might be fulfilled, especially the prophecy in Psalm 108.
Augustine of Hippo · d. 430Catena Aurea (Aquinas, 1274)
But here He proceeds: "While I was with them, I kept them in Thy name." Since I am coming, He says, to Thee, keep them in Thy name, in which I myself have kept them while I was with them. In the Father's name, the Son as man kept His disciples, when placed side by side with them in human presence; but the Father also, in the name of the Son, kept those whom He heard and answered when praying in the name of the Son. For to them had it also been said by the Son Himself: "Verily, verily, I say unto you, whatsoever ye shall ask the Father in my name, He will give it you." But we are not to take this in any such carnal way, as that the Father and Son keep us in turn, with an alternation in the guardianship of both in guarding us, as if one succeeded when the other departed; for we are guarded all at once by the Father, and Son, and Holy Spirit, who is the one true and blessed God. But Scripture does not exalt us save by descending to us: as the Word, by becoming flesh, came down to lift us up, and fell not so as to remain Himself in the depths. If we have known Him who thus descendeth, let us rise with Him who lifteth us up; and let us understand, when He speaks thus, that He is marking a distinction in the persons, without making any separation of the natures. While, therefore, the Son in bodily presence was keeping His disciples, the Father was not waiting the Son's departure in order to succeed to the guardianship, but both were keeping them by Their spiritual power; and when the Son withdrew from them His bodily presence, He retained along with the Father the spiritual guardianship. For when the Son also as man assumed the office of their guardian, He did not withdraw them from the Father's guardianship; and when the Father gave them to the guardianship of the Son, in the very giving He acted not apart from Him to whom He gave them, but gave them to the Son as man, yet not apart from that same Son Himself as God.
Augustine of Hippo · d. 430Tractates on John
The Son therefore goes on to say: "Those that Thou gavest me, I have kept, and none of them is lost, but the son of perdition; that the Scripture might be fulfilled." The betrayer of Christ was called the son of perdition, as foreordained to perdition, according to the Scripture, where it is specially prophesied of him in the 109th Psalm.
Augustine of Hippo · d. 430Tractates on John

Verse 13

"But now I come to thee." Seest thou that the discourse is composed rather in a human manner? So that should any wish from these words to lower the Son, he will lower the Father also. Observe, in proof of this, how from the beginning He speaketh partly as though informing and explaining to Him, partly as enjoining. Informing, as when He saith, "I pray not for the world"; enjoining, as, "I have kept them until now," "and none of them is lost"; and, "do Thou therefore now keep them," He saith. And again, "Thine they were, and Thou hast given them unto Me" and "While I was in the world I kept them." But the solution of all is, that the words were addressed to their infirmity.
John Chrysostom · d. 407Homilies on John
(Tr. cvii) Or thus: That they might have the joy spoken of above: That they may be one, as We are one. This His joy, i. e. bestowed by Him, He says, is to be fulfilled in them: on which account He spoke thus in the world. This joy is the peace and happiness of the life to come. He says He spoke in the world, though He had just now said, I am no more in the world. For, inasmuch as He had not yet departed, He was still here; and inasmuch as He was going to depart, He was in a certain sense not here.
Augustine of Hippo · d. 430Catena Aurea (Aquinas, 1274)
"And now," He says, "come I to Thee; and these things I speak in the world, that they may have my joy fulfilled in themselves." See! He says that He speaketh in the world, when He had said only a little before, "I am no more in the world:" the reason of which we have there explained, or rather have shown that He Himself explained it. Accordingly, on the one hand, as He had not yet departed, He was still here; and because He was on the very point of departure, in a kind of way He was no more here. But what this joy is whereof He says, "That they may have my joy fulfilled in themselves," has already been elucidated above, where He says, "That they may be one, even as we are." This joy of His that is bestowed on them by Him, was to be fulfilled, He says, in them; and for that very end declared that He had spoken in the world. This is that peace and blessedness in the world to come, for the attaining of which we must live temperately, and righteously, and godly in the present.
Augustine of Hippo · d. 430Tractates on John

Verse 14

When having become virtuous we are persecuted by the wicked, or when being desirous of virtue we are mocked at by them, let us not be distracted or angry. For this is the natural course of things, and everywhere virtue is wont to engender hatred from wicked men. For envying those who desire to live properly, and thinking to prepare an excuse for themselves if they can overthrow the credit of others, they hate them as having pursuits opposite to their own, and use every means to shame their way of life. But let not us grieve, for this is a mark of virtue. Wherefore Christ also saith, "If ye were of the world, the world would love its own." And in another place again, "Woe unto you when all men shall speak well of you." Wherefore also He saith here, "I have given them Thy word, and the world hath hated them." Again He telleth the reason for which they were worthy to obtain much care from the Father; "For Thy sake," He saith, "they have been hated, and for Thy word's sake"; so that they would be entitled to all providential care.
John Chrysostom · d. 407Homilies on John
(Tr. cviii) They had not yet experienced these sufferings which they afterwards met with; but, after His custom, He puts the future into the past tense. Then He gives the reason why the world haled them; viz. Because they are not of the world. This was conferred upon them by regeneration; for by nature they were of the world. It was given to them that they should not be of the world, even as He was not of the world; as it follows; Even as I am not of the world. He never was of the world; for even His birth of the form of a servant He received from the Holy Ghost, from Whom they were born again.
Augustine of Hippo · d. 430Catena Aurea (Aquinas, 1274)
While the Lord is still speaking to the Father, and praying for His disciples, He says: "I have given them Thy saying; and the world hath hated them." That hatred they had not yet experienced in those sufferings of their own, which afterwards overtook them; but He speaks thus in His usual way, foretelling the future in words of the past tense. And then, subjoining the reason of their being hated by the world, He says, "Because they are not of the world, even as I am not of the world." This was conferred on them by regeneration; for by generation they were of the world, as He had already said to them, "I have chosen you out of the world." It was therefore a gracious privilege bestowed upon them, that they, like Himself, should not be of the world, through the deliverance which He was giving them from the world. He, however, was never of the world; for even in respect of His servant-form He was born of that Holy Spirit of whom they were born again. For if on that account they were no more of the world, because born again of the Holy Spirit; on the same account He was never of the world, because born of the Holy Spirit.
Augustine of Hippo · d. 430Tractates on John

Verse 15

"I pray not that Thou shouldest take them out of the world, but that Thou shouldest keep them from the evil." Again He simplifieth His language; again He rendereth it more clear; which is the act of one showing, by making entreaty for them with exactness, nothing else but this, that He hath a very tender care for them. Yet He Himself had told them, that the Father would do all things whatsoever they should ask. How then doth He here pray for them? As I said, for no other purpose than to show His love.
John Chrysostom · d. 407Homilies on John
(Tr. cviii) But though they were no longer of the world, it was still necessary that they should be in the world: I pray not that Thou shouldest take them out of the world.
Augustine of Hippo · d. 430Catena Aurea (Aquinas, 1274)
"I pray not," He adds, "that thou shouldest take them out of the world, but that Thou shouldest keep them from the evil." For they still accounted it necessary to be in the world, although they were no longer of it.
Augustine of Hippo · d. 430Tractates on John
As if to say, The time is now at hand, when I shall be taken out of the world; and therefore it is necessary that they should be still left in the world, in order to preach Me and Thee to the world. But that Thou shouldest keep them from the evil; every evil, but especially the evil of schism.
Bede · d. 735Catena Aurea (Aquinas, 1274)

Verse 16

"They are not of the world, even as I am not of the world." How then saith He in another place, "Which Thou gavest Me out of the world; Thine they were"? There He speaketh of their nature; here of wicked actions. And He putteth together a long encomium of them; first, that "they were not of the world"; then, that "the Father Himself had given them"; and that "they had kept His word;" and that on this account "they were hated." And if He saith, "As I am not of the world," be not troubled; for the "as" is not here expressive of unvarying exactness. For as, when in the case of Him and the Father the "as" is used, a great Equality is signified, because of the Relationship in Nature; so when it is used of us and Him, the interval is great, because of the great and infinite interval between the respective natures. For if He "did no sin, neither was guile found in His mouth," how could the Apostles be reckoned equal to Him? What is it then that He saith, "They are not of the world"? "They look to another world, they have nothing common with earth, but are become citizens of heaven." And by these words He showeth His love, when He commendeth them to the Father, and committeth them to Him who begat Him. When He saith, "Keep them," He doth not speak merely of delivering them from dangers, but also with regard to their continuance in the faith.
John Chrysostom · d. 407Homilies on John
(Tr. cviii) He repeats the same thing again; They are not of the world, even as I am not of the world.
Augustine of Hippo · d. 430Catena Aurea (Aquinas, 1274)
Then He repeats the same statement: "They are not of the world, even as I am not of the world. Sanctify them in the truth." For thus are they kept from the evil, as He had previously prayed that they might be. But it may be inquired how they were no more of the world, if they were not yet sanctified in the truth; or, if they already were, why He requests that they should be so. Is it not because even those who are sanctified still continue to make progress in the same sanctification, and grow in holiness; and do not so without the aid of God's grace, but by His sanctifying of their progress, even as He sanctified their outset? And hence the apostle likewise says: "He who hath begun a good work in you, will perform it until the day of Jesus Christ."
Augustine of Hippo · d. 430Tractates on John

Verse 17

"Sanctify them through Thy truth." "Make them holy by the gift of the Spirit, and of right doctrines." As when He saith, "Ye are clean through the word which I spake unto you," so now He saith the same thing, "Instruct them, teach them the truth." "And yet He saith that the Spirit doth this. How then doth He now ask it from the Father?" That thou mayest again learn their equality of Honor. For right doctrines asserted concerning God sanctify the soul. And if He saith that they are sanctified by the word, marvel not. And to show that He speaketh of doctrines, He addeth, "Thy word is truth." That is, "there is no falsehood in it, and all that is said in it must needs come to pass"; and again, it signifieth nothing typical or bodily. As also Paul saith concerning the Church, that He hath sanctified it by the Word. For the Word of God is wont also to cleanse. Moreover, the, "sanctify them," seems to me to signify something else, such as this, "Set them apart for the Word and for preaching."
John Chrysostom · d. 407Homilies on John
(Tr. cviii) Sanctify them through Thy truth: for thus were they to be kept from the evil. But it may be asked, how it was that they were not of the world, when they were not yet sanctified in the truth? Because the sanctified have still to grow in sanctity, and this by the help of God's grace. The heirs of the New Testament are sanctified in that truth, the shadows of which were the sanctification of the Old Testament; they are sanctified in Christ, Who said above, I am the way, the truth, and the life. (c. 14:6) It follows, Thy discourse is truth. The Greek is λόγος, i. e. word. The Father then sanctified them in the truth, i. e. in His Word the Only-Begotten, them, i. e. the heirs of God, and joint-heirs with Christ.
Augustine of Hippo · d. 430Catena Aurea (Aquinas, 1274)
The heirs therefore of the New Testament are sanctified in that truth which was adumbrated in the purifications of the Old Testament; and when they are sanctified in the truth, they are in other words sanctified in Christ, who said in truth "I am the way, and the truth, and the life." As also when He said, "The truth shall make you free," in explanation of His words, He added soon after, "If the Son shall make you free, ye shall be free indeed;" in order to show that what He had previously called the truth, He a minute afterwards denominates the Son. And what else did He mean by the words before us, "Sanctify them in the truth," but, Sanctify them in me? Finally, He proceeds, and doing so fails not to suggest the same with increasing clearness: "Thy speech is truth." What else did He mean than "I am the truth"? For the Greek Gospel has logos, which is also the word that is found in the passage where it is said, "In the beginning was the Word, and the Word was with God, and the Word was God." And that Word at least we know to be the only begotten Son of God, which "was made flesh, and dwelt among us." Hence also there might have been put here as it actually has been put in certain copies "Thy Word is truth;" just as in some copies that other passage is written, "In the beginning was the speech." But in the Greek without any variation it is logos in both cases. The Father therefore sanctifies in the truth, that is, in His own Word, in His Only begotten, His own heirs and His (the Son's) co-heirs.
Augustine of Hippo · d. 430Tractates on John

Verse 18

"As Thou hast sent Me into the world, even so have I also sent them into the world." As Paul also saith, "Having put in us the word of reconciliation." For the same end for which Christ came, for the same did these take possession of the world. In this place again the "as" is not put to signify resemblance in the case of Himself and the Apostles; for how was it possible for men to be sent otherwise? But it was His custom to speak of the future as having come to pass.
John Chrysostom · d. 407Homilies on John
But now He still goes on to speak of the apostles, for He proceeds to add, "As Thou hast sent me into the world, even so have I also sent them into the world." Whom did He so send but His apostles? For even the very name of apostles, which is a Greek word, signifies in Latin nothing more than, those that are sent. God, therefore, sent His Son, not in sinful flesh, but in the likeness of sinful flesh; and His Son sent those who, born themselves in sinful flesh, were sanctified by Him from the defilement of sin.
Augustine of Hippo · d. 430Tractates on John
As Thou hast sent Me into the world, even so have I also sent them into the world. For what Christ was sent into the world, for the same end were they; as saith Paul, God was in Christ reconciling the world unto Himself; and hath given to us the word of reconciliation. (2 cor. 5:19) As does not express perfect likeness between our Lord and His Apostles, but only as much as was possible in men. Have sent them, He says, according to His custom of putting the past for the future.
Glossa Ordinaria · d. 1274Catena Aurea (Aquinas, 1274)

Verse 19

"And for their sakes I sanctify Myself, that they also might be sanctified in the truth." What is, "I sanctify Myself"? "I offer to Thee a sacrifice." Now all sacrifices are called "holy," and those are specially called "holy things," which are laid up for God. For whereas of old in type the sanctification was by the sheep, but now it is not in type, but by the truth itself, He therefore saith, "That they may be sanctified in Thy truth." "For I both dedicate them to Thee, and make them an offering"; this He saith, either because their Head was being made so, or because they also were sacrificed; for, "Present," it saith, "your bodies a living sacrifice, holy"; and, "We were counted as sheep for the slaughter." And He maketh them; without death, a sacrifice and offering; for that He alluded to His own sacrifice, when He said, "I sanctify," is clear from what follows.
John Chrysostom · d. 407Homilies on John
(Tr. cviii) It is manifest by this, that He is still speaking of the Apostles; for the very word Apostle means in the Greek, sent. But since they are His members, in that He is the Head of the Church, He says, And for their sakes I sanctify Myself; i. e. I in Myself sanctify them, since they are Myself. And to make it more clear that this was His meaning, He adds, That they also might be sanctified through the truth, i. e. in Me; inasmuch as the Word is truth, in which the Son of man was sanctified from the time that the Word was made flesh. For then He sanctified Himself in Himself, i. e. Himself as man, in Himself as the Word: the Word and man being one Christ. But of His members it is that He saith, And for their sakes I sanctify Myself, i. e. them in Me, since in Me both they and I are. That they also might be sanctified in truth: they also, i. e. even as Myself; and in the truth, i. e. Myself.
Augustine of Hippo · d. 430Catena Aurea (Aquinas, 1274)
But since, on the ground that the Mediator between God and men, the man Christ Jesus, has become Head of the Church, they are His members; therefore He says in the words that follow, "And for their sakes I sanctify myself." For what means He by the words, "And for their sakes I sanctify myself," but I sanctify them in myself, since they also are [part of] myself? For those of whom He so speaks are, as I have said, His members; and the head and body are one Christ, as the apostle teaches when he says of the seed of Abraham, "And if ye be Christ's, then are ye Abraham's seed," after having said before, "He saith not, And to seeds, as in many, but as in one, And to thy seed, which is Christ." If, then, the seed of Abraham is Christ, what else is declared to those to whom he says, "Then are ye Abraham's seed," but then are ye Christ? Of the same character is what this very apostle said in another place: "Now I rejoice in my sufferings for you, and fill up that which is lacking of the afflictions of Christ in my flesh." He said not, of my afflictions, but "of Christ's;" for he was a member of Christ, and in his persecutions, such as it behoved Christ to suffer in the whole of His body, he also was filling up his own share of His afflictions. And to be assured of the certainty of this in the present passage, give heed to what follows. For after saying, "And for their sakes I sanctify myself," to let us understand that He thereby meant that He would sanctify them in Himself, He immediately added, "That they also may be sanctified in the truth." And what else is this but in me, in accordance with the fact that the truth is that Word in the beginning which is God? In whom also the Son of man was Himself sanctified from the beginning of His creation, when the Word was made flesh, for the Word and the man became one person. Then accordingly He sanctified Himself in Himself, that is, Himself the man in Himself the Word; for the Word and the man is one Christ, who sanctifies the manhood in the Word. But in behalf of His members He says, "And for their sakes I,"-that is, that the benefit may be also theirs, for they too are [included in the] I, just as it benefited me in myself, because I am man apart from them-" I sanctify myself," that is, I sanctify them as if it were my own self in me, since in me they also are I. "That they also may be sanctified in the truth." For what else mean the words "they also" but ["they"] in the same way as I; "in the truth," and that "truth" am I?
Augustine of Hippo · d. 430Tractates on John

Verse 20

"Neither pray I for these alone, but for them also who shall believe." For since He was dying for them, and said, that "For their sakes I sanctify Myself," lest any one should think that He did this for the Apostles only, He added, "Neither pray I for these only, but for them also who believe on Me through their word." By this again He revived their souls, showing that the disciples should be many. For because He made common what they possessed peculiarly, He comforteth them by showing that they were being made the cause of the salvation of others.
John Chrysostom · d. 407Homilies on John
The Lord Jesus, in the now close proximity of His passion, after praying for His disciples, whom He also named apostles, with whom He had partaken of that last supper from which His betrayer had taken his departure on being revealed by the sop of bread, and with whom, after the latter's departure, and before beginning His prayer in their behalf, He had already spoken at length, conjoined all others also who were yet to believe on Him, and said to the Father, "Neither pray I for these alone," that is, for the disciples who were with Him at the time, "but for them also," He adds, "who shall believe on me through their word." Whereby He wished all His own to be understood: not only such as were then in the flesh, but those also who were yet to come. For all that have since believed on Him have doubtless believed, and shall yet believe till He come, through the word of the apostles; for to themselves He had said, "And ye also shall bear witness, because ye have been with me from the beginning;" and by them was the gospel ministered even before it was written, and every one assuredly who believeth on Christ believeth the gospel. Accordingly, those who He says should believe on Him through their word, are not to be understood as referring only to such as heard the apostles themselves while they lived in the flesh; but others also after their decease, and we, too, born long afterwards, have believed on Christ through their word. For they that were then with Him preached to the others what they had heard from Him; and so their word, that we too might believe, has found its way to us, and wherever His Church exists, and shall yet reach down to posterity, whoever and wherever they be who shall hereafter believe on Him.
Augustine of Hippo · d. 430Tractates on John
In this prayer, therefore, Jesus may seem to have omitted praying for some of His own, unless we carefully examine His words in the prayer itself. For if He prayed first for those, as we have already shown, who were then with Him, and afterwards for those also who should believe on Him through their word, it may be said that He prayed not for those who were neither with Him when He so spake, nor afterwards believed through their word, but had done so at some previous time either of themselves, or in some other supposable manner. For was Nathanael with Him at that time? Was Joseph of Arimathea, who begged His body from Pilate, and of whom this same evangelist John testifies that he was already His disciple? Were His mother, Mary, and other women who, we know from the Gospel, had been prior to that time His disciples? Were those with Him then, of whom this evangelist John frequently says, "Many believed on Him"? For whence came the multitude of those who, with branches of trees, partly preceded and partly followed Him as He sat on the ass, saying, "Blessed is He that cometh in the name of the Lord;" and along with them the children of whom He Himself declared that the prophecy had been uttered, "Out of the mouth of babes and of sucklings Thou hast perfected praise"? Whence the five hundred brethren, to all of whom at once He would not have appeared after His resurrection had they not previously believed on Him? Whence that hundred and nine who, with the eleven, were a hundred and twenty, when, being assembled together after His ascension, they waited and received the promise of the Holy Spirit? Whence came all these, save from those of whom it was said, "Many believed on Him"? For them, therefore, the Saviour did not at this time pray, seeing it was for those He prayed who were then with Him, and for others not who had already, but who were yet to believe on Him through their word. But these were certainly not with Him on that occasion, and had already believed on Him at some previous period. I say nothing of the aged Simeon, who believed on Him when an infant; of Anna the prophetess; of Zachariah and Elisabeth, who prophesied of Him before He was born of the Virgin; of their son John, His forerunner, the friend of the Bridegroom, who both recognized Him in the Holy Spirit, and preached Him in His absence, and pointed Him out when He was present to the recognition of others; -I say nothing of these, as it might be replied that He ought not to have prayed for such when dead, who had gone hence with their great merits; for a similar answer is also given in connection with the righteous of olden time. For which of them could have been saved from the damnation awaiting the whole mass of perdition, which has been caused by one man, had he not believed, through the revelation of the Spirit, in the one Mediator between God and men as yet to come in the flesh? But behoved He to pray for the apostles, and not to pray for so many who were still alive, but were not then with Him, and had already at some previous period been brought to the faith? Who is there that would say so?
Augustine of Hippo · d. 430Tractates on John
We are therefore to understand that their faith in Him was not yet such as He wished it to be, inasmuch as even Peter himself, to whom, on making the confession, "Thou art the Christ, the Son of the living God," He had borne so excellent a testimony, was disposed rather to hinder Him from dying than to believe in His resurrection when dead, and hence was called immediately thereafter by the same of Satan. Those, accordingly, are found to be the greater in faith who were long since deceased, and yet, through the revelation of the Spirit, had no manner of doubt that Christ would rise again, than those who, after attaining to the belief that He should redeem Israel, at the sight of His death lost all the hope they previously possessed regarding Him. The best thing for us, therefore, to believe is, that after His resurrection, when the Holy Spirit was bestowed, and the apostles taught and confirmed, and from its outset constituted teachers in the Church, others, through their word, attained the proper faith in Christ, or, in other words, that they then got firm hold of the faith of His resurrection. And in this way also, that all those who seemed to have already believed on Him really belonged to the number of those for whom He prayed, when He said, "Neither pray I for these alone, but for them also who shall believe on me through their word."
Augustine of Hippo · d. 430Tractates on John
But we have still in reserve for the further solution of this question the blessed apostle, and that robber who was a villain in wickedness, but a believer on the cross. For the Apostle Paul tells us that he was made an apostle not of men, nor by man, but by Jesus Christ: and speaking of his own gospel, he says, "For I neither received it of man, neither did I learn it, but by the revelation of Jesus Christ." How then was he among those of whom it is said, "They shall believe on me through their word"? On the other hand, the robber believed at the very time when in the case of the teachers themselves such faith as they previously possessed had utterly failed. Not even he, therefore, believed on Christ through their word, and yet his faith was such that he confessed that He whom he saw nailed to the cross would not only rise again, but would also reign, when he said, "Remember me when Thou comest into Thy kingdom."
Augustine of Hippo · d. 430Tractates on John
Accordingly it remains that if we are to believe that the Lord Jesus, in this prayer, prayed for all of His own who either then were or should thereafter be in this life, which is a state of trial upon earth, we must so understand the expression, "through their word," as to believe that it here signified the word of faith itself which they preached in the world, and that it was called their word because it was primarily and principally preached by them. For it was already in the course of being preached by them in the earth when Paul received that same word of theirs by the revelation of Jesus Christ. Whence also it came about that he compared the Gospel with them, lest by any means he had run, or should run, in vain; and they gave him their right hand because in him also they found, although not given him by them, their own word which they were already preaching, and in which they were now established. And in regard to this word of the resurrection of Christ, it is said by the same apostle, "Whether it were I, or they, so we preach, and so ye believed;" and again, "This is the word of faith," he says, "which we preach, that if thou shalt confess with thy mouth that Jesus is the Lord, and shalt believe in thine heart that God hath raised Him from the dead, thou shalt be saved." And in the Acts of the Apostles we read that in Christ, God hath marked out [the ground of] faith unto all men, in that He hath raised Him from the dead. Accordingly, this word of faith, because principally and primarily preached by the apostles who adhered to Him, was called their word. Not, however, on that account does it cease to be the word of God because it is called their word; for the same apostle says that the Thessalonians received it from him "not as the word of men, but, as it is in truth, the word of God." "Of God," for the very reason that it was freely given by God; but called "their word," because primarily and principally committed to them by God to be preached. In the same way also the thief mentioned above had in the matter of his own faith their word, which was called theirs precisely because the preaching of it primarily and principally pertained to the office they filled.
Augustine of Hippo · d. 430Tractates on John
And once more, when murmuring arose among the Grecian widows in reference to the serving of the tables, previous to the time when Paul was brought to the faith of Christ, the reply given by the apostles, who before then had adhered to the Lord, was: "It is not good that we should leave the word of God, and serve tables." Then it was that they provided for the ordination of deacons, that they themselves might not be drawn aside from the duty of preaching the word. Hence that was properly enough called their word which is the word of faith, whereby all, from whatever quarter they had heard it, believed on Christ, or, as yet to hear it, should thereafter believe. In this prayer, therefore, all whom He redeemed, whether then alive or thereafter to live in the flesh, were prayed for by our Redeemer when, praying for the apostles who were then with Him, He also conjoined those who were yet to believe on Him through their word.
Augustine of Hippo · d. 430Tractates on John
(Tr. cix) When our Lord had prayed for His disciples, whom He named also Apostles, He added a prayer for all others who should believe on Him; Neither pray I for these alone, but for all others who shall believe on Me through their word.
Augustine of Hippo · d. 430Catena Aurea (Aquinas, 1274)
(Tr. cix) All, i. e. not only those who were then alive, but those who were to be born; not those only who heard the Apostles themselves, but us who were born long after their death. We have all believed in Christ through their word: for they first heard that word from Christ, and then preached it to others, and so it has come down, and will go down to all posterity. We may see that in this prayer there are some disciples whom He does not pray for; for those, i. e. who were neither with Him at the time, nor were about to believe on Him afterwards through the Apostles' word, but believed already. Was Nathanael with Him then, or Joseph of Arimathea, and many others, who, John says, believed on Him? I do not mention old Simeon, or Anna the prophetess, Zacharias, Elisabeth, or John the Baptist; for it might be answered that it was not necessary to pray for dead persons, such as these who departed with such rich merits. With respect to the former then we must understand that they did not yet believe in Him, as He wished, but that after His resurrection, when the Apostles were taught and strengthened by the Holy Spirit, they attained to a right faith. The case of Paul however still remains, An Apostle not of men, or by men; (Gal. 1:1) and that of the robber, who believed when even the teachers themselves of the faith fell away. We must understand then, their word, to mean the word of faith itself which they preached to the world; it being called their word, because it was preached in the first instance and principally by them; for it was being preached by them, when Paul received it by revelation from Jesus Christ Himself. And in this sense the robber too believed their word. Wherefore in this prayer the Redeemer prays for all whom He redeemed, both present and to come. And then follows the thing itself which He prays for, That they all may be one. He asks that for all, which he asked above for the disciples; that all both we and they may be one.
Augustine of Hippo · d. 430Catena Aurea (Aquinas, 1274)

Verse 21

(vii de Trin) And this unity is recommended by the great example of unity: As Thou, Father, art in Me, and I in Thee, that they also may be one in Us, i. e. that as the Father is in the Son, and the Son in the Father, so, after the likeness of this unity, all may be one in the Father and in the Son. (viii. de Trin) Heretics endeavouring to get over the words, I and My Father are one, as a proving unity of nature, and to reduce them to mean a unity simply of natural love, and agreement of will, bring forwards these words of our Lord's as an example of this kind of unity: That they may be all one, as Thou, Father, art in Me, and I in Thee. But though impiety can cheat its own understanding, it cannot alter the meaning of the words themselves. For they who are born again of a nature that gives unity in life eternal, they cease to be one in will merely, acquiring the same nature by their regeneration: but the Father and Son alone are properly one, because God, only-begotten of God, can only exist in that nature from which He is derived. (viii. de Trin) Or, the world will believe that the Son is sent from the Father, for that reason, viz. because all who believe in Him are one in the Father and the Son.
Hilary of Poitiers · d. 367Catena Aurea (Aquinas, 1274)
After having thus spoken concerning their salvation, and their being sanctified by faith and the Sacrifice, He afterwards speaketh of concord, and finally closeth his discourse with this, having begun with it and ended in it. For at the beginning He saith, "A new commandment I give unto you"; and here, "That they all may be one, as Thou, Father, art in Me and I in Thee." Here again the "as" doth not denote exact similarity in their case, (for it was not possible for them in so great a degree,) but only as far as was possible for men. Just as when He saith "Be ye merciful, as your Father."
John Chrysostom · d. 407Homilies on John
But what is, "In Us"? In the faith which is on Us. Because nothing so offends all men as divisions, He provideth that they should be one. "What then," saith some one, "did He effect this?" Certainly He effected it. For all who believe through the Apostles are one, though some from among them were torn away. Nor did this escape His knowledge, He even foretold it, and showed that it proceeded from men's slack-mindedness. "That the world may believe that Thou hast sent Me." As He said in the beginning, "By this shall all men know that ye are My disciples, if ye love one another," And how should they hence believe? "Because," He saith, "Thou art a God of peace." If therefore they observe the same as those of whom they have learnt, their hearers shall know the teacher by the disciples, but if they quarrel, men shall deny that they are the disciples of a God of peace, and will not allow that I, not being peaceable, have been sent from Thee. Seest thou how, unto the end, He proveth His unanimity with the Father?
John Chrysostom · d. 407Homilies on John
Elsewhere He says of Himself and the Father, We will come and make Our abode with Him; by the mention of two persons, stopping the mouths of the Sabellians. Here by saying that the Father comes to the disciples through Him, He refutes the notion of the Arians.
John Chrysostom · d. 407Catena Aurea (Aquinas, 1274)
After the Lord Jesus had prayed for His disciples whom He had with Him at the time, and had conjoined with them others who were also His own, by saying, "Neither pray I for these alone, but for them also who shall believe on me through their word," as if we were inquiring what or wherefore He prayed for them, He straightway subjoined, "That they all may be one; as Thou, Father, [art] in me, and I in Thee, that they also may be one in us." And a little above, while still praying for the disciples alone who were then with Him, He said, "Holy Father, keep in Thine own name those whom Thou hast given me, that they may be one, as we are." It is the same thing, therefore, that He now also prayed for in our behalf, as He did at that time in theirs, namely, that all-to wit, both we and they-may be one. And here we must take particular notice that the Lord did not say that we all may be one, but, "that they all may be one; as Thou Father, in me, and I in Thee"; because He had also said before of the disciples who were with Him, "That they may be one, as we are." The Father, therefore, is in the Son, and the Son in the Father, in such a way as to be one, because they are of one substance; but while we may indeed be in them, we cannot be one with them; for they and we are not of one substance, in as far as the Son is God along with the Father. But in as far as He is man, He is of the same substance as we are. But at present He wished rather to call attention to that other statement which He made use of in another place, "I and the Father are one," where He intimated that His own nature was the same with that of the Father. And accordingly, though the Father and Son, or even the Holy Spirit, are in us, we must not suppose that they are of one nature with ourselves. And hence they are in us, or we are in them, in this sense, that they are one in their own nature, and we are one in ours. For they are in us, as God in His temple; but we are in them, as the creature in its Creator.
Augustine of Hippo · d. 430Tractates on John
But then after saying, "That they also may be one in us," He added, "That the world may believe that Thou hast sent me." What does He mean by this? Is it that the world will then be brought to the faith, when we shall all be one in the Father and Son? Is not such a state the everlasting peace, and the reward of faith, rather than faith itself? For we shall be one not in order to our believing, but because we have believed. But although in this life, because of the common faith itself, all who believe in one are one according to the words of the apostle, "For ye are all one in Christ Jesus;" even thus we are one, not in order to our believing, but because we do believe. What, then, is meant by the words, "That they all may be one, that the world may believe"? This, doubtless, that the "all" are themselves the believing world. For those who shall be one are not of one class, and the world that is thereafter to believe on this very ground that these shall be one, of another; since it is perfectly certain that He says, "That they all may be one," of those of whom He had said before, "Neither pray I for these alone, but for those also who shall believe on me through their word," immediately adding as He does, "That they all may be one." And this "all," what is it but the world; not certainly that which is hostile, but that which is believing? For you see here that He who had said, "I pray not for the world," now prayeth for the world that it may believe. For there is a world whereof it is written, "That we might not be condemned with this world." For that world He prayeth not, for He is fully aware to what it is predestinated. And there is a world whereof it is written, "For the Son of man came not to condemn the world, but that the world through Him might be saved;" and hence the apostle also says, "God was in Christ, reconciling the world unto Himself." For this world it is that He prayeth, in saying, "That the world may believe that Thou hast sent me." For through this faith the world is reconciled unto God when it believes in the Christ whom God has sent.
Augustine of Hippo · d. 430Tractates on John
How, then, are we to understand Him when He says, "That they also may be one in us, that the world may believe that Thou hast sent me," but just in this way, that He did not assign the cause of the world believing to the fact that those others are one, as if it believed on the ground that it saw them to be one; for the world itself here consisteth of all who by their own believing become one; but in His prayer He said, "That the world may believe," just as in His prayer He also said, "That they all may be one;" and still further in the same prayer, "That they also may be one in us." For the words, "they all may be one," are equivalent to "the world may believe," since it is by believing that they become one, perfectly one; that is, those who, although one by nature, had ceased to be so by their mutual dissensions. In fine, if the verb which He uses, "I pray," be understood in the third clause, or rather, to make the whole fuller, be everywhere supplied, the explanation of this sentence will be all the clearer: I pray "that they all may be one; as Thou, Father, in me, and I in Thee;" I pray "that they also may be one in us;" I pray "that the world may believe that Thou hast sent me." And, mark, He added the words "in us" in order that we may know that our being made one in that love of unchanging faithfulness is to be attributed to the grace of God, and not to ourselves: just as the apostle, after saying, "For ye were at one time darkness, but now are ye light," that none might attribute the doing of this to themselves, added, "in the Lord."
Augustine of Hippo · d. 430Tractates on John
(Tr. cx) We must particularly observe here, that our Lord did not say, that we may be all one, but that they may be all one, as Thou, Father, in Me, and I in Thee, are one, understood. For the Father is so in the Son, that They are one, because They are of one substance; but we can be one in Them, but not with Them; because we and They are not of one substance. They are in us, and we in Them, so as that They are one in Their nature, we one in ours. They are in us, as God is in the temple; we in Them, as the creature is in its Creator. Wherefore He adds, in Us, to show, that our being made one by charity, is to be attributed to the grace of God, not to ourselves.
Augustine of Hippo · d. 430Catena Aurea (Aquinas, 1274)
(iv. de. Trin. c. ix) Or that in ourselves we cannot be one, severed from each other by diverse pleasures, and lusts, and the pollution of sin, from which we must be cleansed by a Mediator, in order to be one in Him.
Augustine of Hippo · d. 430Catena Aurea (Aquinas, 1274)
(Tr. cx) But why does He say, That the world may believe that Thou hast sent Me? Will the world believe when we shall all be one in the Father and the Son? Is not this unity that peace eternal, which is the reward of faith, rather than faith itself? For though in this life all of us who hold in the same common faith are one, yet even this unity is not a means to belief, but the consequence of it. What means then, That all may be one, that the world may believe? He prays for the world when He says, Neither pray I for these alone, but for all those who shall believe on Me through their word. Whereby it appears that He does not make this unity the cause of the world believing, but prays that the world may believe, as He prays that they all may be one. The meaning will be clearer if we always put in the word ask; I ask that they all may be one; I ask that they may be one in Us; I ask that the world may believe that Thou hast sent Me.
Augustine of Hippo · d. 430Catena Aurea (Aquinas, 1274)

Verse 22

"And the glory which Thou gavest Me, I have given them." That by miracles, that by doctrines, and, that they should be of one soul; for this is glory, that they should be one, and greater even than miracles. As men admire God because there is no strife or discord in That Nature, and this is His greatest glory, "so too let these," He saith, "from this cause become glorious." "And how," saith some one, "doth He ask the Father to give this to them, when He saith that He Himself giveth it?" Whether His discourse be concerning miracles, or unanimity, or peace, He is seen Himself to have given these things to them; whence it is clear that the petition is made for the sake of their comfort.
John Chrysostom · d. 407Homilies on John
Furthermore, our Saviour in thus praying to the Father showed Himself to be man; while He now also shows that He Himself, as being God along with the Father, doeth that which He prayeth for, when He says, "And the glory which Thou gavest me, I have given them." And what was that glory but immortality, which human nature was henceforth to receive in Him? For not even He Himself had as yet received it, but in His own customary way, on account of the absolute fixedness of predestination, He intimates what is future in verbs of the past tense, because being now on the point of being glorified, or in other words, raised up again by the Father, He Himself is going to raise us up to the same glory in the end. What we have here is similar to what He says elsewhere, "As the Father raiseth up the dead, and quickeneth them, even so the Son quickeneth whom He will." And "whom," but just the same as the Father? "For what things soever the Father doeth," not other things, but "these also doeth the Son," not in a different way, but "in like manner." And in this way He also raised up even His own self. For to this effect he said, "Destroy this temple, and in three days I will raise it up again." Accordingly the glory of immortality, which He says had been given Him by the Father, He must be also understood as having bestowed upon Himself, although He does not say it. For on this very account He more frequently says that the Father alone doeth, what He Himself also doeth along with the Father, that everything whatever He may attribute to Him of whom He is.
Augustine of Hippo · d. 430Tractates on John
(Tr. cx) Then our Saviour, Who, by praying to the Father, showed Himself to be man, now shows that, being God with the Father, He doth what He prays for: And the glory which Thou gavest Me, I have given them. What glory, but immortality, which human nature was about to receive in Him? For that which was to be by unchangeable predestination, though future, He expresses by the past tense. That glory of immortality, which He says was given Him by the Father, we must understand He gave Himself also. For when the Son is silent of His own cooperation in the Father's work, He shows His humility: when He is silent of the Father's cooperation in His work, He shows His equality. In this way here He neither disconnects Himself with the Father's work, when He says, The glory which Thou gavest Me, nor the Father with His work, when He says, I have given them. But as He was pleased by prayer to the Father to obtain that all might be one, so now He is pleased to effect the same by His own gift; for He continues, That all may be one, even as We are one.
Augustine of Hippo · d. 430Catena Aurea (Aquinas, 1274)

Verse 22–23

(viii. de Trin) By this giving and receiving of honour, then, all are one. But I do not yet apprehend in what way this makes all one. Our Lord, however, explains the gradation and order in the consummating of this unity, when He adds, I in them, and Thou in Me; so that inasmuch as He was in the Father by His divine nature, we in Him by His incarnation, and He again in us by the mystery of the sacrament, a perfect union by means of a Mediator was established.
Hilary of Poitiers · d. 367Catena Aurea (Aquinas, 1274)

Verse 23

"I in them, and Thou in Me." "How gave He the glory?" By being in them, and having the Father with Him, so as to weld them together. But in another place He speaketh not so; He saith not that the Father cometh by Him, but, "that He and the Father come, and take up their abode with him," "there" removing the suspicion of Sabellius, "here" that of Arius.
John Chrysostom · d. 407Homilies on John
"That they may be made perfect in one, and that the world may know that Thou hast sent Me." He saith these latter words immediately after the other, to show that peace hath more power to attract men than a miracle; for as it is the nature of strife to separate, so it is that of agreement to weld together. "And I have loved them as Thou hast loved Me." Here again the "as" means, as far as it is possible for a man to be loved; and the sure proof of His love is His giving Himself for them. After having told them that they shall be in safety, that they shall not be overturned, that they shall be holy, that many shall believe through them, that they shall enjoy great glory, that not He alone loved them, but the Father also; He next telleth them of what shall be after their sojourning here, concerning the prizes and crowns laid up for them.
John Chrysostom · d. 407Homilies on John
And then He added: "I in them, and Thou in me, that they may be made perfect in one." Here He briefly intimated Himself as the Mediator between God and men. Nor was this said in any such way as if the Father were not in us, or we were not in the Father; since He had also said in another place, "We will come unto him, and make our abode with him;" and a little before in this present passage He had not said, "I in them and Thou in me," as He said now; or, They in me, and I in Thee; but, "Thou in me, and I in Thee, and they in us." Accordingly, when He now says, "I in them, and Thou in me," the words take this form in reference to the person of the Mediator, like that other expression used by the apostle, "Ye are Christ's, and Christ is God's." But in adding, "That they may be made perfect in one," He showed that the reconciliation, which is effected by the Mediator, is carried to the very length of bringing us to the enjoyment of that perfect blessedness, which is thenceforth incapable of further addition. Hence the words that follow, "That the world may know that Thou hast sent me," are not, I think, to be taken as if He had again said, "That the world may believe;" for sometimes, to know, is also used in the same sense as to believe, as it is in the words He uttered some time before: "And they have known truly that I came out from Thee, and they have believed that Thou didst send me." He expressed the same thing by the later words, "they have believed," as He had done by the earlier, "they have known." But inasmuch as He here speaks of the consummation, the knowledge must be taken for such, as it shall then be by sight, and not, as it now is, by faith. For an order seems to have been preserved in reference to what He said a little before, "that the world may believe;" while here it is, "that the world may know." For although He said there, "that they all may be one," and "may be one in us," yet He did not say, "they may be made perfect in one," and so subjoined the words, "that the world may believe that Thou hast sent me;" but here He said, "That they may be made perfect in one," and then added, not, "that the world may believe," but, "that the world may know that Thou hast sent me." For so long as we believe what we do not see, we are not yet made perfect, as we shall be when we have merited the sight of that which we believe. Most correctly, therefore, did He say in that previous place, "That the world may believe," and here "That the world may know;" yet both there and here, "that Thou hast sent me;" that we may know, so far as belongs to the inseparable love of the Father and the Son, that at present we only believe what we are on the way, by believing, to know.
Augustine of Hippo · d. 430Tractates on John
And had He said, That they may know that Thou hast sent me, it would be just of the same force as what He actually does say, "that the world may know." For they are the world that abideth not in enmity, as doth the world that is foreordained to damnation; but one that out of an enemy has been transformed into a friend, and on whose account "God was in Christ reconciling the world unto Himself." Therefore said He, "I in them, and Thou in me;" as if He had said, I in those to whom Thou hast sent me; and Thou in me, reconciling the world unto Thyself through me. In close relation to these come also His further words: "And Thou hast loved them as Thou hast loved me." That is to say, in the Son the Father loveth us, because in Him He hath chosen us before the foundation of the world. For He who loveth the Only-begotten, certainly loveth also His members which, through His instrumentality, He engrafted into Him by adoption. But we are not on this account equal to the only-begotten Son, by whom we have been created and re-created, that it is said, "Thou hast loved them as [Thou hast] also [loved] me." For one does not always intimate equality when he says, As this, so also that other; but sometimes only, Because this is, so also is the other; or, That the one is, in order that the other may be also. For who could say that the apostles were sent by Christ into the world in exactly the same way as He Himself was sent by the Father? For, to say nothing of other differences, which it would be tedious to mention, they at all events were sent when they were already men; but He was sent in order that He might be man; and yet He said above, "As Thou hast sent me into the world, even so have I sent them into the world;" as if He had said, Because Thou hast sent me, I have sent them. So also in the passage before us He says, "Thou hast loved them, as Thou hast loved me;" which is nothing else than this, Thou hast loved them because that Thou hast also loved me. For He could not but love the members of the Son, seeing that He loveth the Son Himself; nor is there any other reason for loving His members, save that He loveth Himself. But He loveth the Son as regards His Godhead, because He begat Him equal with Himself; He loveth Him also in regard to what He is as man, because the Only-begotten Word was Himself made flesh, and on account of the Word is the flesh of the Word dear to Him; but He loveth us, inasmuch as we are the members of Him whom He loveth; and in order that we might be so, He loved us on this account before we existed.
Augustine of Hippo · d. 430Tractates on John
The love, therefore, wherewith God loveth, is incomprehensible and immutable. For it was not from the time that we were reconciled unto Him by the blood of His Son that He began to love us; but He did so before the foundation of the world, that we also might be His sons along with His Only-begotten, before as yet we had any existence of our own. Let not the fact, then, of our having been reconciled unto God through the death of His Son be so listened to or so understood, as if the Son reconciled us to Him in this respect, that He now began to love those whom He formerly hated, in the same way as enemy is reconciled to enemy, so that thereafter they become friends, and mutual love takes the place of their mutual hatred; but we were reconciled unto Him who already loved us, but with whom we were at enmity because of our sin. Whether I say the truth on this, let the apostle testify, when he says: "God commendeth His love toward us, in that, while we were yet sinners, Christ died for us." He, therefore, had love toward us even when we were practising enmity against Him and working iniquity; and yet to Him it is said with perfect truth, "Thou hatest, O Lord, all workers of iniquity." Accordingly, in a wonderful and divine manner, even when He hated us, He loved us; for He hated us, in so far as we were not what He Himself had made; and because our own iniquity had not in every part consumed His work, He knew at once both how, in each of us, to hate what we had done, and to love what He had done.
Augustine of Hippo · d. 430Tractates on John
(Tr. cx. 4) Nor is this said, however, as if to mean that the Father was not in us, or we in the Father. He only means to say, that He is Mediator between God and man. And what He adds, That they may be made perfect in one, shows that the reconciliation made by this Mediator, was carried on even to the enjoyment of everlasting blessedness. So what follows, That the world may know that Thou hast sent Me, must not be taken to mean the same as the words just above, That the world may believe. For as long as we believe what we do not see, we are not yet made perfect, as we shall be when we have merited to see what we believe. So that when He speaks of their being made perfect, we are to understand such a knowledge as shall be by sight, not such as is by faith. These that believe are the world, not a permanent enemy, but changed from an enemy to a friend; as it follows: And hast loved them, as Thou hast loved Me. The Father loves us in the Son, because He elected us in Him. These words do not prove that we are equal to the Only Begotten Son; for this mode of expression, as one thing so another, does not always signify equality. It sometimes only means, because one thing, therefore another. And this is its meaning here: Thou hast loved them, as Thou hast loved Me, i. e. Thou hast loved them, because Thou hast loved Me. There is no reason for God loving His members, but that He loves him. But since He hateth nothing that He hath made, who can adequately express how much He loves the members of His Only Begotten Son, and still more the Only Begotten Himself.
Augustine of Hippo · d. 430Catena Aurea (Aquinas, 1274)

Verse 24

"Father," He saith, "I will that they also whom Thou hast given Me, be with Me where I am." "Then dost Thou gain by prayer, and dost Thou not yet possess that concerning which they enquired continually, saying, 'Whither goest Thou?' What sayest Thou? How then didst Thou say to them, 'Ye shall sit upon twelve thrones'? How didst Thou promise other things more and greater?" Seest thou that He saith all in the way of condescension? since how would He have said, "Thou shalt follow afterwards"? But He speaketh thus with a view to a fuller conviction and demonstration of His love.
John Chrysostom · d. 407Homilies on John
"That they may behold My glory which Thou hast given Me." This again is a sign of His being of one mind with the Father, of a higher character than those former, for He saith, "Before the foundation of the world," yet hath it also a certain condescension; for, "Thou hast given Me," He saith. Now if this be not the case, I would gladly ask the gainsayers a question. He that giveth, giveth to one subsisting; did the Father then, having first begotten the Son, afterwards give Him glory, having before allowed Him to be without glory? And how could this be reasonable? Seest that the "He gave," is, "He begot"?
John Chrysostom · d. 407Homilies on John
But why said He not, "That they may share My glory," instead of, "That they may behold My glory"? Here He implieth, that all that rest is, the looking on the Son of God. This certainly it is which causes them to be glorified; as Paul saith, "With open face mirroring the glory of the Lord." For as they who look on the sunbeams, and enjoy a very clear atmosphere, draw their enjoyment from their sight, so then also, and in much greater degree, this will cause us pleasure. At the same time also He showeth, that what they should behold was not the body then seen, but some awful Substance.
John Chrysostom · d. 407Homilies on John
The Lord Jesus raises up His people to a great hope, than which there could not possibly be a greater. Listen and rejoice in hope, that, since the present is not a life to be loved, but to be tolerated, you may have the power of patient endurance amid all its tribulation. Listen, I say, and weigh well to what it is that our hopes are exalted. Christ Jesus saith, The Son of God, the Only-begotten, who is co-eternal and equal with the Father, saith: He, who for our sakes became man, but became not, like every man besides, a liar, saith: the Way, the Life, the Truth saith: He who overcame the world, saith of those for whom He overcame it: listen, believe, hope, desire what He saith: "Father," He says, "I will that they also whom Thou hast given me be with me where I am." Who are these who He says were given Him by the Father? Are they not those of whom He says in another place, "No man cometh unto me, unless the Father, who hath sent me, draw him"? We already know if we have made any beneficial progress in this Gospel, how it is that the things which He says the Father doeth, He Himself doeth likewise along with the Father. They are those, therefore, whom He has received from the Father, whom He Himself has also chosen out of the world, and chosen that they may be no more of the world, even as He also is not of the world; and yet that they also may be a world that believeth and knoweth that Christ has been sent by God the Father that the world might be delivered from the world, and so, as a world that was to be reconciled unto God, might not be condemned with the world that lieth in enmity.
Augustine of Hippo · d. 430Tractates on John
For so He says in the beginning of this prayer: "Thou hast given Him power over all flesh," that is, over every man, "that He should give eternal life to as many as Thou hast given Him." Here He makes it clear that He has indeed received power over all men, that, as the future Judge of quick and dead, He may deliver whom He pleases, and condemn whom He pleases; but that these were given Him that to all of them He should give eternal life. For so He says: "That He should give eternal life to as many as Thou hast given Him." Accordingly they were not given Him that from them He should withhold eternal life; although over them also the power has been given Him, inasmuch as He has received it over all flesh, in other words, over every man. In this way the world that has been reconciled will be delivered from the hostile world, when He putteth into exercise His power over it, to send it away into death eternal; but the other He maketh His own that He may give it everlasting life. Accordingly, to every one, without fail, of His own sheep the Good Shepherd, as to every one of His members the great Head, hath promised this reward, that where He is, there also we shall be with Him; nor can that be otherwise which the omnipotent Son declared to be His will to the omnipotent Father. For there also is the Holy Spirit, equally eternal, equally God, the one Spirit of the two, the substance of the will of both.
Augustine of Hippo · d. 430Tractates on John
For the words that we read of Him as uttering on the eve of His passion, "Yet not, Father, as I will, but as Thou wilt," as if the Father has or had one will, and the Son another, are the echo of our infirmity, however faith-pervaded, which our Head transfigured in His own person, when He likewise bare our iniquities. But that the will of the Father and the Son is one, of both of whom also there is but one Spirit, by including whom we come to the knowledge of the Trinity, let piety believe, even though our infirmity meanwhile permitteth us not to understand.
Augustine of Hippo · d. 430Tractates on John
But as we have already, in a way proportionate to the brevity of our discourse, spoken of the objects of the promise, and of its own stability; let us now look at this one point, as far as we are able, what it is that He was pleased to promise when He said, "I will that they also whom Thou hast given me be with me where I am." As far as pertains to the creaturehood wherein He was made of the seed of David according to the flesh, not even He Himself was yet where He would afterwards be: but He could say in this way, "where I am," to let us understand that He was soon to ascend into heaven, so that He spake of Himself as being already there, where He was presently to be. He could do so also in the same way as He had said on a former occasion, when speaking to Nicodemus, "No man ascendeth into heaven, save He that came down from heaven, even the Son of man who is in heaven." For there also He did not say, Will be, but "is," because of the oneness of person, wherein God is at once man, and man God. He promised, therefore, that we should be in heaven; for thither the servant-form, which He received of the Virgin, has been elevated, and set at the right hand of the Father.
Augustine of Hippo · d. 430Tractates on John
Because of the same blessed hope the apostle also says: "But God, who is rich in mercy, for His great love wherewith He loved us, even when we were dead in sins, hath quickened us together with Christ; by whose grace we are saved; and hath raised us up together, and made us sit together in heavenly places in Christ Jesus." And so accordingly we may understand the Lord to have said, "That where I am, there they may be also." He, indeed, said of Himself that He was there already; but of us He merely declared that He wished us to be there with Him, without any indication that we were there already. But what the Lord said that He wished to be done, the apostle spake of as already accomplished. For he said not, He will yet raise us up, and make us sit in heavenly places; but, "hath raised us up, and made us sit in heavenly places:" for it is not without good grounds, but in believing assurance, that he reckons as already done what he is certain will yet be done.
Augustine of Hippo · d. 430Tractates on John
But if it is in respect of the form of God, wherein He is equal to the Father, that we would be inclined to understand His words, "I will that they also be with me, where I am," let our mind get quit of every thought of material images: whatever the soul has had presented to it, that is endowed with length, or breadth, or thickness, tinted by the light with any sort of bodily hue, or diffused through local space of any kind, whether finite or infinite, let it, as far as possible, turn away from all such notions the glance of its contemplation on the inward bent of its thoughts. And let us not be making inquiries as to where the Son, the Father's co-equal, is, since no one has yet found out where He is not. But if any one would inquire, let him inquire rather how he may be with Him; not everywhere as He is, but wherever He may be. For when He said to the man that was expiating his crimes on the tree, and making confession unto salvation, "Today shall thou be with me in paradise," in respect to His human nature His own soul was on that very day to be in hell, His flesh in the sepulchre; but as respected His Godhead He was certainly also in paradise. And therefore the soul of the thief, absolved from his by-gone crimes, and already in the blessed enjoyment of His grace, although it could not be everywhere as He was, yet could on that very day be also with Him in paradise, from which He, who is always everywhere, had not withdrawn.
Augustine of Hippo · d. 430Tractates on John
On this account, doubtless, it was not enough for Him to say, "I will that they also be where I am;" but He added, "with me." For to be with Him is the chief good. For even the miserable can be where He is, since wheresoever any are, there is He also; but the blessed only are with Him, because it is only of Him that they can be blessed. Was it not truly said to God, "If I ascend into heaven, Thou art there; and if I go down into hell, Thou art present?" or is not Christ after all that Wisdom of God which "penetrateth everywhere because of its purity"? But the light shineth in darkness and the darkness comprehendeth it not. And similarly, to take a kind of illustration from what is visible, although greatly unlike, as the blind man, even though he be where the light is, is yet not himself with the light, but is really absent from that which is present; so the unbeliever and profane, or even the believer and pious, because not yet competent to gaze on the light of wisdom, although he cannot be anywhere that Christ is not there likewise, yet is not himself with Christ, I mean in actual sight. For we cannot doubt that the true believer is with Christ by faith; because in reference to this He saith, "He that is not with me is against me." But when He said to God the Father, "I will that they also whom Thou hast given me be with me where I am," He spake exclusively of that sight wherein we shall see Him as He is.
Augustine of Hippo · d. 430Tractates on John
Let no one disturb the clearness of the meaning by any cloudy contradiction; but let what follows furnish its testimony to the words that precede. For after saying, "I will that they also be with me where I am," He went on immediately to add, "That they may behold my glory, which Thou gavest me: for Thou lovedst me before the foundation of the world." "That they may behold," He said; not, that they may believe. This is faith's wages, not faith itself. For if faith has been correctly defined in the Epistle to the Hebrews as "the assurance [conviction] of things that are not seen," why may not the wages of faith be defined, the beholding of things which were hoped for in faith? For when we shall see the glory which the Father hath given the Son, even though we may understand what is spoken of in this passage, not as that [glory] which the Father gave His co-equal Son in begetting Him, but as that which He gave Him, when become the Son of man, after the death of the cross;-when, I say, we shall see that glory of the Son, then of a certainty shall take place the judgment of the quick and the dead, and then shall the wicked be taken away that he may not behold the glory of the Lord; and what [glory], save that of His Godhead? For blessed are the pure in heart, for they shall see God: and because the wicked are not pure in heart, therefore they shall not see. Then shall they go away into everlasting punishment; for so shall the wicked be taken away, that he may not behold the glory of the Lord: but the righteous shall go into life eternal. And what is life eternal? "That they may know Thee, the only true God, and Jesus Christ, whom Thou hast sent": not, indeed, as those knew Him, who although impure in heart, yet were able to see Him as He sat in judgment in His glorified servant-form; but as He is yet to be known by the pure in heart, as the only true God, the Son along with the Father and Holy Spirit, because the Trinity itself is the only true God.
Augustine of Hippo · d. 430Tractates on John
If, then, it is in reference to His Godhead as the Son of God, equal and co-eternal with the Father, that we take the words, "I will that they also be with me where I am," we shall be with Christ in the Father; but He in His own way, we in ours, wherever we may be in body. For if localities are to be understood, and such as contain incorporeal beings, and everything has a place where it is, the eternal place of Christ where He always is, is the Father Himself, and the place of the Father is the Son; for "I," He said, "am in the Father, and the Father in me;" and in this prayer, "As Thou, Father, art in me, and I in Thee:" and they are our place, because there follows, "That they also may be one in us:" and we are God's place, inasmuch as we are His temple; even as He, who died for us and liveth for us, also prayeth for us, that we may be one in them; because "His [dwelling] place was made in peace, and His habitation in Zion," which we are. But who is qualified to think on such places or what is in them, apart from the idea of space-defined capacities and material masses? Yet no little progress is made, if at least, when any such idea presents itself to the eye of the mind, it is denied, rejected, and reprobated: and a certain kind of light is, as far as possible, thought of, in which such things are perceived as deserving only to be denied, rejected, and reprobated; and the certainty of that light is known and loved, so that from thence an upward movement is begun in us, and an effort made to reach into places farther within: and when the mind through its own infirmity and still inferior purity has failed to penetrate them it is driven back again, not without the sighings of love and the tears of ardent longing, and continues to bear in patience until it is purified by faith, and prepared by the holiness of the inward life to be able to take up its abode therein.
Augustine of Hippo · d. 430Tractates on John
How, then, shall we not be with Christ where He is, when we shall be with Him in the Father in whom He is? On this, also, the apostle is not without something to say to us, although we are not yet in possession of the reality, but only cherishing the hope. For he says, "If ye be risen with Christ, seek those things which are above, where Christ sitteth on the right hand of God: set your affections on things above, not on things on the earth. For ye have died," he adds, "and your life is hid with Christ in God." Here, you see, our life is meanwhile in faith and hope with Christ, where He is; because it is with Christ in God. That, you see, is as if already accomplished for which He prayed, when He said, "I will that they also be with me where I am;" but now only by faith. And when will it be accomplished by actual sight? "When Christ," he says, "[who is] your life, shall appear, then shall ye also appear with Him in glory." Then shall we appear as that which we then shall be; for it shall then be apparent that it was not without good grounds that we believed and hoped we should become so, before it actually took place. He will do this, to whom the Son, after saying, "That they may behold my glory, which Thou gavest me," immediately added, "For Thou lovedst me before the foundation of the world." For in Him He loved us also before the foundation of the world, and then foreordained what He was to do in the end of the world.
Augustine of Hippo · d. 430Tractates on John
(Tr. cxi. 1) These are they whom He has received from the Father, whom He also chose out of the world; as He saith at the beginning of this prayer, Thou hast given Him power over all flesh, i. e. all mankind, That He should give eternal life to as many as Thou hast given Him. Wherein He shows that He had received power over all men, to deliver whom He would, and to condemn whom He would. Wherefore it is to all His members that He promises this reward, that where He is, they may be also. Nor can that but be done, which the Almighty Son saith that He wishes to the Almighty Father: for the Father and the Son have one will, which, if weakness prevent us from comprehending, piety must believe. Where I am: so far as pertains to the creature, He was made of the seed of David according to the flesh: He might say, Where I am, meaning where He was shortly to be, i. e. heaven. In heaven then, He promises us, we shall be. For thither was the form of a servant raised, which He had taken from the Virgin, and there placed on the right hand of God.
Augustine of Hippo · d. 430Catena Aurea (Aquinas, 1274)
(Tr. cxi) But as respects the form of God, wherein He is equal to the Father, if we understand these words, that they may be with Me where I am, with reference to that, then away with all bodily ideas, and enquire not where the Son, Who is equal to the Father, is: for no one hath discovered where He is not. Wherefore it was not enough for Him to say, I will that they may be where I am, but He adds, with Me. For to be with Him is the great good: even the miserable can be where He is, but only the happy can be with Him. And as in the ease of the visible, though very different be whatever example we take, a blind man will serve for one, as a blind man though He is where the light is, yet is not himself with the light, but is absent from it in its presence, so not only the unbelieving, but the believing, though they cannot be where Christ is not, yet are not themselves with Christ by sight: by faith we cannot doubt but that a believer is with Christ. But here He is speaking of that sight wherein we shall see Him as He is; as He adds, That they may behold My glory, which Thou hast given Me. That they may behold, He says, not, that they may believe. It is the reward of faith which He speaks of, not faith itself.
Augustine of Hippo · d. 430Catena Aurea (Aquinas, 1274)
(Tr. cxi. 3) When then we shall have seen the glory which the Father gave the Son, though by this glory we do not understand here, that which He gave to the equal Son when He begat Him, but that which He gave to the Son of man, after His crucifixion; then shall the judgment be, then shall the wicked be taken away, that he see not the glory of the Lord: what glory but that whereby He is God? If then we take their words, That they may be with Me where I am, to be spoken by Him as Son of God, in that case they must have a higher meaning, viz. that we shall be in the Father with Christ. As He immediately adds, That they may see My glory which Thou hast given Me; and then, Which Thou gavest Me before the foundation of the world. For in Him He loved us before the foundation of the world, and then predestined what He should do at the end of the world.
Augustine of Hippo · d. 430Catena Aurea (Aquinas, 1274)
(Moral.) What means then what the Truth saith above, No man hath ascended into heaven, but He that came down from heaven, even the Son of man which is in heaven. (John 3:13) Yet here is no discrepancy, for our Lord being the Head of His members, the reprobates excluded, He is alone with us. And therefore, we making one with Him, whence He came alone in Himself, thither He returns alone in us.
Gregory the Dialogist · d. 604Catena Aurea (Aquinas, 1274)
That which He calls glory then is the love wherewith He was loved with the Father before the foundation of the world. And in that glory He loved us too before the foundation of the world.
Bede · d. 735Catena Aurea (Aquinas, 1274)

Verse 25

"O righteous Father, the world hath not known Thee." What meaneth this? What connection hath it? He here showeth that no man knoweth God, save those only who have come to know the Son. And what He saith is of this kind: "I wished all to be so, yet they have not known Thee, although they had no complaint against Thee." For this is the meaning of, "O righteous Father." And here He seemeth to me to speak these words, as vexed that they would not know One so just and good. For since the Jews had said that they knew God, but that He knew Him not, at this He aimeth, saying, "For Thou lovedst Me before the foundation of the world"; thus putting together a defense against the accusations of the Jews. For how could He who had received glory, who was loved before the foundation of the world, who desired to have them as witnesses of that glory, how could He be opposed to the Father? "This then is not true which the Jews say, that they know Thee, and that I know Thee not; on the contrary, I know Thee, and they have not known Thee."
John Chrysostom · d. 407Homilies on John
"And these have known that Thou hast sent Me." Seest thou that He alludeth to those, who said that He was not from God, and all is finally summed up to meet this argument?
John Chrysostom · d. 407Homilies on John
"O righteous Father," He saith, "the world hath not known Thee." Just because Thou art righteous it hath not known Thee. It is as that world which has been predestined to condemnation really deserved, that it hath not known Him; while the world which He hath reconciled unto Himself through Christ hath known Him not of merit, but by grace. For what else is the knowing of Him, but eternal life which, while He undoubtedly withheld it from the condemned world, He bestowed on the reconciled. On that very account, therefore, the world hath not known Thee, because Thou art righteous, and hast rendered unto it according to its deserts, that it should not know Thee: while on the same account the reconciled world hath known Thee, because Thou art merciful, and, not for any merit of its own, but by grace, hast supplied it with the needed help to know Thee. And then there follows, "But I have known Thee." He is the Fountain of grace, who is by nature God, and, by grace ineffable, man also of the Holy Spirit and the Virgin: and then on His own behalf, because the grace of God is through Jesus Christ our Lord, He adds, "And these have known that Thou hast sent me." Such is the reconciled world. But it is because Thou hast sent me that they have known: by grace, therefore, have they known.
Augustine of Hippo · d. 430Tractates on John
(Tr. cxi. 5) Or thus; What is to know Him, but eternal life, which He gave not to a condemned but to a reconciled world? For this reason the world hath not known Thee; because Thou art just, and hast punished them with this ignorance of Thee, in reward for their misdeeds. And for this reason the reconciled world knows Thee, because Thou art merciful, and hast vouchsafed this knowledge, not in consequence of their merits, but of thy grace. It follows: But I have known Thee. He is God the fountain of grace by nature, man of the Holy Ghost and Virgin by grace ineffable. Then because the grace of God is through Jesus Christ, He says, And they have known Me, i. e. the reconciled world have known Me, by grace, forasmuch as Thou hast sent Me.
Augustine of Hippo · d. 430Catena Aurea (Aquinas, 1274)
After then that He had prayed for believers, and promised them so many good things, another prayer follows worthy of His mercy and benignity: O righteous Father, the world hath not known Thee; as if to say, I would wish that all men obtained these good things, which I have asked for the believing. But inasmuch as they have not known Thee, they shall not obtain the glory and crown.
Theophylact of Ohrid · d. 1107Catena Aurea (Aquinas, 1274)

Verse 26

"And I have declared unto them Thy Name, and will declare it." "Yet thou sayest that perfect knowledge is from the Spirit." "But the things of the Spirit are Mine." "That the love wherewith Thou hast loved Me may remain in them, and I in them." "For if they learn who Thou art, then they shall know that I am not separated from Thee, but one of the greatly beloved, and a true Son, and closely knit to Thee. And those who are rightly persuaded of this, will keep both the faith which is on Me and perfect love; and I will abide in them." Seest thou how He hath arrived at a good end, finishing off the discourse with love, the mother of all blessings?
John Chrysostom · d. 407Homilies on John
"And I have made known to them," He says, "Thy name, and will make it known." I have made it known by faith, I will make it known by sight: I have made it known to those whose present sojourn in a strange land has its appointed end, I will make it known to those whose reign as kings shall be endless. "That the love," He adds, "wherewith Thou hast loved me, may be in them, and I in them." But how else is the love wherewith the Father loved the Son in us also, but because we are His members and are loved in Him, since He is loved in the totality of His person, as both Head and members? Therefore He added, "and I in them;" as if saying, Since I am also in them. For in one sense He is in us as in His temple; but in another, because we are also Himself, seeing that, in accordance with His becoming man, that He might be our Head, we are His body. The Saviour's prayer is finished, His passion begins; let us, therefore, also finish the present discourse, that we may treat of His passion, as He granteth us grace, in others to follow.
Augustine of Hippo · d. 430Tractates on John
(Tr. cxi. 5) And I have made known Thy name to them by faith, and will make it known by sight: that the love wherewith Thou hast loved Me may be in them. (2 Tim. 4:7) The Apostle uses a like phrase, I have fought a good fight, by a good fight being the more common form. The love wherewith the Father loveth the Son in us, can only be in us because we are His members, and we are loved in Him when He is loved wholly, i. e. both head and body. And therefore He adds, And I in them; He is in us, as in His temple, we in Him as our Head.
Augustine of Hippo · d. 430Catena Aurea (Aquinas, 1274)
