John Chrysostom
Catena Aurea · Johannesevangelium 3
John answered and said, A man can receive nothing, except it be given him from heaven. Ye yourselves bear me witness, that I said, I am not the Christ, but that I am sent before him. He that hath the bride is the bridegroom; but the friend of the bridegroom, which standeth and heareth him, rejoiceth greatly because of the bridegroom’s voice: this my joy therefore is fulfilled. He must increase, but I must decrease.
(Hom. xxix. 2) And see; the very argument by which they thought to have overthrown Christ, To whom, thou barest witness, he turns against them; Ye yourselves bear me witness, that I said, I am not the Christ; as if he said, If ye think my witness true, ye must acknowledge Him more worthy of honour than myself. He adds, But that I was sent before Him; that is to say, I am a servant, and perform the commission of the Father which sent me; my witness is not from favour or partiality; I say that which was given me to say.
