John Calvin Commentary John 3:26

"And they came unto John, and said to him, Rabbi, he that was with thee beyond the Jordan, to whom thou hast borne witness, behold, the same baptizeth, and all men come to him." — John 3:26 (ASV)

To whom thou gavest testimony. By this argument they attempt either to make Christ inferior to John, or to show that John, by honoring him, had laid him under obligations; for they consider that John conferred a favor on Christ by adorning him with such honorable titles.

As if it had not been John’s duty to make such a proclamation, or rather, as if it had not been John’s highest dignity to be the herald of the Son of God.

Nothing could have been more unreasonable than to make Christ inferior to John because John’s testimony was highly favorable, for we know what that testimony was.

The expression which they use — all men come to Christ — is the language of envious persons and proceeds from sinful ambition, for they are afraid that the crowd will immediately forsake their master.
