Augustine of Hippo, on John 17:9

“I pray for them: I pray not for the world, but for them whom thou hast given me: because they are thine:”

“(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.”
