Then said Jesus unto them,
When you have lifted up the Son of man, then shall you know that I am he, and that I do nothing of myself; but as my Father has taught me, I speak these things.
All Commentaries on John 8:28 Go To John 8
John Chrysostom
AD 407
Or the connection is this: When His miracles and teaching had failed to convert men, He spoke of the cross; When you have lifted up the Son of man, then you shall know that I am He: as if to say, you think that you have killed Me; but I say that you 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 has taught Me, I speak these things. Here He shows 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.
He gives now a humbler turn to the discourse: And He that sent Me. That this might not be thought however to imply inferiority, He says, Is with Me. The former is His dispensation, the latter His divinity.
Or, Hemeans it as an answer to those who were constantly saying that He was not from God, and that because He did not keep the sabbath; I do always, He says, do those things that please Him; showing that the breaking the sabbath even was pleasing to Him. He takes care in everyway to show that He does nothing contrary to the Father. And as this was speaking more aftera human fashion, the Evangelist adds, As He spoke these words many believed in Him; as ifto say, Do not be disturbed at hearing so humble a speech from Christ; for those who had heard the greatest doctrines from Him, and were not persuaded, were persuaded by these words of humility. These then believed on Him, yet not as they ought; but only out of joy, and approbation of His humble way of speaking. And this the Evangelist shows in his subsequent narration, which relates their unjust proceedings towards Him.
