Hilary of Poitiers
Catena Aurea · Johannesevangelium 7
Then said some of them of Jerusalem, Is not this he, whom they seek to kill? But, lo, he speaketh boldly, and they say nothing unto him. Do the rulers know indeed that this is the very Christ? Howbeit we know this man whence he is: but when Christ cometh, no man knoweth whence he is. Then cried Jesus in the temple as he taught, saying, Ye both know me, and ye know whence I am: and I am not come of myself, but he that sent me is true, whom ye know not. But I know him: for I am from him, and he hath sent me. Then they sought to take him: but no man laid hands on him, because his hour was not yet come.
(vi. de Trin. ultra med.) I ask however, does the being from Him express a work of creation, or a birth by generation? If a work of creation, then every thing which is created is from Him. And how then does not all creation know the Father, if the Son knows Him, because He is from Him? But if the knowledge of the Father is peculiar to Him, as being from Him, then the being from Him is peculiar to Him also; i. e. the being the true Son of God by nature. So you have then a peculiar knowledge springing from a peculiar generation. To prevent however any heresy applying the being from Him, to the time of His advent, He adds, And He hath sent Me: thus preserving the order of the Gospel sacrament; first announcing Himself born, and then sent.
