John 5:34

Perhaps some (woman) will say: "To me it is not necessary to be approved by men; for I do not require the testimony of men: God is the inspector of the heart.

(Hom. xl. 2) Even the witness of John was the witness of God: for what he said, God taught him. But to anticipate their asking how it appeared that God taught John, as if the Jews had objected that John's witness might not be true, our Lord anticipates them by saying, "Ye sought him yourselves to enquire of him; that is why I use his testimony, for I need it not." He adds, But these things I say that ye might be saved. As if He said, I being God, needed not this human kind of testimony. But, since ye attend more to him, and think him more worthy of credit than any one else, while ye do not believe me, though I work miracles; for this cause I remind you of his testimony. But had they not received John's testimony? Before they have time to ask this, He answers it: He was a burning and a shining light, and ye were willing for a season to rejoice in his light. He says this to show, how lightly they had held by John, and how soon they had left him, thus preventing him from leading them to Christ. He calls him a candle, because John had not his light from himself, but from the grace of the Holy Spirit.

"But I receive not testimony from man." "Why then hast Thou brought forward that of John?" His testimony was not the "testimony of man," for, saith he, "He that sent me to baptize with water, He said unto me." So that John's testimony was the testimony of God; for having learned from Him he said what he did. But that none should ask, "Whence is it clear that he learnt from God?" and stop at this, He abundantly silences them by still addressing Himself to their thoughts. For neither was it likely that many would know these things; they had hitherto given heed unto John as to one who spake of himself, and therefore Christ saith, "I receive not testimony from man." And that the Jews might not ask, "And if Thou wert not about to receive the testimony of man, and by it to strengthen Thyself, why hast Thou brought forward this man's testimony?" see how He correcteth this contradiction by what He addeth. For after saying, "I receive not testimony from man," He hath added, "But these things I say, that ye may be saved." What He saith is of this kind; "I, being God, needed not the witness of John which is man's witness, yet because ye gave more heed to him, believe him more trustworthy than any, ran to him as to a prophet, (for all the city was poured forth to Jordan,) and have not believed on Me, even when working miracles, therefore I remind you of that witness of his."
