John Chrysostom
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.
(Hom. l. 1) By which He discloses what was in their minds. I am not, He seems to say, of the number of those who have come without reason, but He is true that sent Me; and if He is true, He hath sent Me in truth; and therefore He who is sent must needs speak the truth. He then convicts them from their own assertions. For whereas they had said, When Christ cometh, no man knoweth whence He is, He shews that Christ did come from one whom they knew not, i. e. the Father. Wherefore He adds, Whom ye know not.
