John 16:30

(vi. de Trin. c. 34) They believe that He came forth from God, because He does the works of God. For whereas our Lord had said both, I came forth from the Father, and, I am come into the world from the Father, they testified no wonder at the latter words, I am come into the world, which they had often heard before. But their reply shows a belief in and appreciation of the former, I came forth from the Father. And they notice this in their reply: By this we believe that Thou camest forth from God; not adding, and art come into the world, for they knew already that He was sent from God, but had not yet received the doctrine of His eternal generation. That unutterable doctrine they now began to see for the first time in consequence of these words, and therefore reply that He spoke no longer in parables. For God is not born from God after the manner of human birth: His is a coming forth from, rather than a birth from, God. He is one from one; not a portion, not a defection, not a diminution, not a derivation, not a pretension, not a passion, but the birth of living nature from living nature. He is God coming forth from God, not a creature appointed to the name of God; He did not begin to be from nothing, but came forth from an abiding (manente) nature. To come forth, hath the signification of birth, not of beginning.

(Hom. lxxix. 2) But since His answer met what was in their minds, they add, Now we are sure that Thou knowest all things. See how imperfect they yet were, after so many and great things now at last to say, Now we are sure &c. saying it too as if they were conferring a favour. And needest not that any man should ask thee; i. e. Thou knowest what offends us, before we tell Thee, and Thou hast relieved us by saying that the Father loveth us.

It was from this diet that they drew the knowledge that He knew all things, and needed not that any one should ask Him: and, indeed, why they said this, is a topic worthy of inquiry. For one would think they ought rather to have said, Thou needest not to ask any one; not, "That any one should ask Thee." They had just said, We are sure that Thou knowest all things:" and surely He that knoweth all things is accustomed rather to be questioned by those who do not know, that in reply to their questions they may hear what they wish from Him who knoweth all things; and not to be Himself the questioner, as if wishing to know something, when He knoweth all things. What, then, are we to understand by this, that, when apparently they ought to have said to Him, whom they knew to be omniscient, Thou needest not to ask any man, they considered it more befitting to say, "Thou needest not that any man should ask Thee"? Yea, is it not the case that we read of both being done; to wit, that the Lord both asked, and was asked questions? But this latter is speedily answered: for this was needful not for Him, but for those rather whom He questioned, or by whom He was questioned. For He never questioned any for the purpose of learning anything from them, but for the purpose rather of teaching them. And for those who put questions to Him, as desirous of learning something of Him, it was assuredly needful to be made acquainted with some things by Him who knew everything.

(Tr. ciii. 2) Why this remark? To one Who knew all things, instead of saying, Thou needest not that any man should ask Thee; it would have been more appropriate to have said, Thou needest not to ask any man: yet we know that both of these were done, viz. that our Lord both asked questions, and was asked. But this is soon explained; for both were for the benefit, not of Himself, but of those whom He asked questions of, or by whom He was asked. He asked questions of men not in order to learn Himself, but to teach them: and in the case of those who asked questions of Him, such questions were necessary to them in order to gain the knowledge they wanted; but they were not necessary to Him to tell Him what that was, because He knew the wish of the enquirer, before the question was put. Thus to know men's thoughts beforehand was no great thing for the Lord, but to the minds of babes it was a great thing: By this we know that Thou camest, forth from God.

The inward state of Christ's disciples, when before His passion He talked with them as with children of great things, but in such a way as befitted the great things to be spoken to children, because, having not yet received the Holy Spirit, as they did after His resurrection, either by His own breathing upon them, or by descent from above, they had a mental capacity for the human rather than the divine, is everywhere declared through the Gospel by numerous testimonies; and of a piece therewith, is what they said in the lesson before us. For, says the evangelist, "His disciples say unto Him: Lo, now speakest Thou plainly, and utterest no proverb. Now we are sure that Thou knowest all things, and needest not that any man should ask Thee: by this we believe that Thou camest forth from God." The Lord Himself had said shortly before, "These things have I spoken unto you in proverbs: the hour cometh, when I shall no more speak to you in proverbs." How, then, say they, "Lo, now speakest Thou plainly, and utterest no proverb"? Was the hour, indeed, already come, when He had promised that He would no more speak unto them in proverbs? Certainly that such an hour had not yet come, and when thus that hour is still the subject of promise when He was to speak without proverbs, why say they, "Lo, now speakest Thou plainly, and utterest no proverb;" but just because those things, which He knows to be proverbs to those who have no understanding, they are still so far from understanding, that they do not even understand that they do not understand them? For they were babes, and had as yet no spiritual discernment of what they heard regarding things that had to do not with the body, but with the spirit.
