John Chrysostom
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.
(Hom. lv. 2) In answer then to their question, Art Thou greater than our father Abraham, He shews them that He is greater than Abraham; Your father Abraham rejoiced to see My day: he saw it, and was glad; he must have rejoiced, because My day would benefit him, which is to acknowledge Me greater than himself.
