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.
(v. de Tr. 3) But it must be clear to every one that the reality of any thing is evidenced by its power. For that is true wheat, which when rising with grain and fenced with ears, and shaken out by the winnowing machine, and ground into corn, and baked into bread, and taken for food, fulfils the nature and function of bread. I ask then wherein the truth of Divinity is wanting to the Son, Who hath the nature and virtue of Divinity. For He so made use of the virtue of His nature, as to cause to be things which were not, and to do every thing which seemed good to Him.
