But I receive not testimony from man: but these things I say, that you might be saved.
All Commentaries on John 5:34 Go To John 5
Cyril of Alexandria
AD 444
He doth not reject the word of John as useless, nor declare the witness of the truth to be of none effect (for He would with justice have seemed to have wrought absurdity against Himself, by unreasonably dismissing from credence him whom He sent to cry. Prepare ye the way of the Lord, make straight the paths of our God) but as striving with the unbounded disobedience of the Jews He proceeds to what is better and of more weight, saying that not of necessity is testimony to Himself from voice of man admitted, but rather giving them more glorious proof from the Authority befitting Him Who is by Nature God, and from the Excellence of the Divine Miracles. For a person will sometimes reject the voice of man, as not true, even though he be haply enrolled among the saints. Which some not scrupling to do, used to oppose the words of the Prophets, crying out. Speak unto us other things and declare unto us another deceit: and yet besides these, certain of them of Jerusalem, or of the land of Judah, who had escaped into Egypt: to wit, Azariah the son of Hoshaiah, and Johanan the son of Kareah and all the proud men, as it is written, openly disbelieving the prophecies of Jeremiah, said, Thou speakest falsely, the Lord sent thee not to say to us, Go not into Egypt. But demonstration through miracles, what gainsaying will it admit of; and the being borne witness to by the Excellencies of God the Father, what mode of stubbornness will it yet grant to the faultfinders? And verily Nicodemus (he was one of their rulers, and ranked among those in authority) gave incontrovertible testimony from His miracles, saying, Rabbi, we know that Thou art a Teacher come from God, for no man can do these miracles that THOU doest, except God be with Him.
Since then to disbelieve even the holy Baptist himself who brought testimony as far as words go, was not too much for the malice of the Jews, He says again, in a sort of irony, The blessed Baptist hath borne witness to the truth, even though questioned by you, but since nothing has been left untried by you, and ye have foolhardily accustomed yourselves to launch forth into all manner of reviling, ye have, it is likely, rejected his voice. And since this too seems to you to be right, be it so: I am haply persuaded, I agree with you, I will put aside for your sakes the voice of John too, and with you except against his testimony: I have the Father from above bearing testimony. But teaching again that the expression implies assent for argument's sake, He profitably subjoined, But these things I say that YE might be saved, that is, I used this manner of speech to you, not that the truth is so, but for argument's sake, that by every means YE may be saved.
