John 1:31

(Tr. iv. c. 12, 13) Now when our Lord became known, it was unnecessary to prepare a way for Him; for to those who knew Him, He became His own way. And therefore John's baptism did not last long, but only so long as to show our Lord's humility. (Tr. v. c. 5.). Our Lord received baptism from a servant, in order to give us such a lesson of humility as might prepare us for receiving the grace of baptism. And that the servant's baptism might not be set before the Lord's, others were baptized with it; who after receiving it, had to receive our Lord's baptism: whereas those who first received our Lord's baptism, did not receive the servant's after.

"And I knew Him not," he saith. Here he renders his testimony free from suspicion, by showing that it was not from human friendship, but had been caused by divine revelation. "I knew Him not," he saith. How then couldest thou be a trustworthy witness? How shalt thou teach others, while thou thyself art ignorant? He did not say "I know Him not," but, "I knew Him not"; so that in this way he would be shown most trustworthy; for why should he have shown favor to one of whom he was ignorant? "But that He should be made manifest unto Israel, therefore am I come baptizing with water." He then did not need baptism, nor had that layer any other object than to prepare for all others a way to faith on Christ. For be did not say, "that I might cleanse those who are baptized," or, "that I might deliver them from their sins," but, "that He should be made manifest unto Israel." "And why, tell me, could he not without baptism have preached and brought the multitudes to Him?" But in this way it would not have been by any means easy. For they would not so all have run together, if the preaching had been without the baptism; they would not by the comparison have learned His superiority. For the multitude came together not to hear his words, but for what? To be "baptized, confessing their sins." But when they came, they were taught the matters concerning Christ, and the difference of His baptism. Yet even this of John was of greater dignity than the Jewish, and therefore all ran to it; yet even so it was imperfect.

And I knew Him not, but that He should be made manifest to Israel, therefore am I come baptizing with water. He that leaped in the depth of the womb of his mother at the voice of the Holy Virgin while yet bearing the Lord, prophet before the travail-pang, disciple in the womb, says of the Saviour, I knew Him not, and says truly, for he does not lie. For God knows all things of Himself and untaught, but the creature, by being taught. For the Spirit indwelling in the Saints, fulfils what is lacking, and gives to human nature His Own good, I mean, knowledge of things to come, and of the hidden mysteries. Therefore the holy Baptist saying that he does not know the Lord, will by no means speak untruly, in regard of the property of human nature, and the measure befitting the creature, but will attribute the knowledge of all things to God Alone, Who through the Holy Ghost enlighteneth man to the apprehension of hidden things. And very profitably doth he say that of himself he knew not Christ, but is come for that very purpose, to make Him manifest to Israel, that he may not seem to run of his own accord to bear testimony, nor be thought by any the minister of his own will, but the worker of the Divine dispensation, the minister of the Counsel from above revealing to him the Lamb Which taketh away the sin of the world. In order therefore that the Jews may the more easily come to believe on our Saviour Christ, and may have the most worthy conception of Him, he says that having not known Him, he knows Him, that they may understand then at length God Who revealed Him, and awestruck at the judgment from above, may receive his word concerning Him, and, seeing the servant so great, may proportionally estimate the Dignity of the Master. For his saying, that he was come to make Him manifest to Israel, how does it not denote the care belonging to a servant?
