Hilary of Poitiers
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.
(ix. de Trin. 31) If Christ be God, not begotten, but unbegotten, then let this receiving be thought weakness. But not if His receiving of power signifies His begetting, in which He received what He is. This gift cannot be counted for weakness. For the Father is such in that He gives; the Son remains God in that He hath received the power of giving eternal life.
