Theophylact of Ohrid
Catena Aurea · Johannesevangelium 8
Then said the Jews unto him, Now we know that thou hast a devil. Abraham is dead, and the prophets; and thou sayest, If a man keep my saying, he shall never taste of death. Art thou greater than our father Abraham, which is dead? and the prophets are dead; whom makest thou thyself? Jesus answered, If I honour myself, my honour is nothing; it is my Father that honoureth me; of whom ye say, that he is your God: Yet ye have not known him; but I know him: and if I should say, I know him not, I shall be a liar like unto you: but I know him, and keep his saying. Your father Abraham rejoiced to see my day: and he saw it, and was glad.
For had they known the Father really, they would have reverenced the Son. But they even despise God, who in the Law forbad murder, by their clamours against Christ. Wherefore He says, Ye have not known Him.
