John Chrysostom
Catena Aurea · Johannesevangelium 17
These words spake Jesus, and lifted up his eyes to heaven, and said, Father, the hour is come; glorify thy Son, that thy Son also may glorify thee: As thou hast given him power over all flesh, that he should give eternal life to as many as thou hast given him. And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent. I have glorified thee on the earth: I have finished the work which thou gavest me to do. And now, O Father, glorify thou me with thine own self with the glory which I had with thee before the world was.
(Hom. lxxx) Or, I have finished, i. e. He had done all His own part, or had done the chief of it, that standing for the whole; (for the root of good was planted:) or He connects Himself with the future, as if it were already present.
