Catena Aurea on John 5:31–40: John Chrysostom

He now brings proof of those high declarations respecting Himself. He answers an objection: If I bear witness of Myself, My witness is not true. These are Christ’s own words. But does not Christ in many places bear witness of Himself? And if all this is false, where is our hope of salvation? Whence shall we obtain truth, when the Truth Itself says, My witness is not true. We must believe then that true, here, is said, not with reference to the intrinsic value of His testimony, but to their suspicions; for the Jews might say, We do not believe Thee, because no one who bears witness to himself is to be depended on. In answer then, he puts forth three clear and irrefragable proofs, three witnesses as it were, to the truth of what He had said; the works which He had done, the testimony of the Father, and the preaching of John: putting the least of these foremost, i. e. the preaching of John: There is another that beareth witness of Me: and I know that the witness which he witnesseth of Me is true.
