Catena Aurea on John 3:22–26: John Chrysostom

Meaning, He, Whom thou baptizedst, baptizeth. They did not say expressly, Whom thou baptizedst, for they did not wish to be reminded of the voice from heaven, but, He Who was with thee, i. e. Who was in the situation of a disciple, who was nothing more than any of us, He now separateth Himself from thee, and baptizeth. They add, To Whom thou barest witness; as if to say, Whom thou shewedst to the world, Whom thou madest renowned, He now dares to do as thou dost. Behold, the Same baptizeth. And in addition to this, they urge the probability that John’s doctrines would fall into discredit. All men come to Him.
