Augustine of Hippo
Catena Aurea · Johannesevangelium 8
I know that ye are Abraham’s seed; but ye seek to kill me, because my word hath no place in you. I speak that which I have seen with my Father: and ye do that which ye have seen with your father. They answered and said unto him, Abraham is our father. Jesus saith unto them, If ye were Abraham’s children, ye would do the works of Abraham. But now ye seek to kill me, a man that hath told you the truth, which I have heard of God: this did not Abraham. Ye do the deeds of your father.
(Tr. xlii. 11) Our Lord by His Father wishes us to understand God: as if to say, I have seen the truth, I speak the truth, because I am the truth. If our Lord then speaks the truth which He saw with the Father, it is Himself that He saw, Himself that He speaks; He being Himself the truth of the Father.
