Catena Aurea on John 8:28–30: John Chrysostom

Or the connection is this: When His miracles and teaching had failed to convert men, He spoke of the cross; When ye have lifted up the Son of man, then ye shall know that I am He: as if to say, Ye think that ye have killed Me; but I say that ye shall then, by the evidence of miracles, of My resurrection, and your captivity, know most especially, that I am Christ the Son of God, and that I do not act in opposition to God; But that as My Father hath taught Me, I speak these things. Here He shews the likeness of His substance to the Father’s; and that He says nothing beyond the Paternal intelligence. If I were contrary to God, I should not have moved His anger so much against those who did not hear Me.
