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.
(iii. Tr. c. 10) He doth not say that the day, or the time, but that the hour is come. An hour contains a portion of a day. What was this hour? He was now to be spit upon, scourged, crucified. But the Father glorifies the Son. The sun failed in his course, and with him all the other elements felt that death. The earth trembled under the weight of our Lord hanging on the Cross, and testified that it had not power to hold within it Him who was dying. The Centurion proclaimed, Truly this was the Son of God. (Matt. 27:54) The event answered the prediction. Our Lord had said, Glorify Thy Son, testifying that He was not the Son in name only, but properly the Son. Thy Son, He saith. Many of us are sons of God; but not such is the Son.For He is the proper, true Son by nature, not by adoption, in truth, not in name, by birth, not by creation. Therefore after His glorifying, to the manifestation of the truth there succeeded confession. The Centurion confesses Him to be the true Son of God, that so none of His believers might doubt what one of His persecutors could not deny.
