John 17:10

"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.

(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.

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.

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.
