Tractates on the Gospel of John

^5. Accordingly He commends to the Father's care those whom He was about to leave by His bodily absence, saying: “Holy Father, keep through Your own name those whom You have 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. But there is still a passage in what follows, where we must have a more careful discussion of this subject.
