John 1:31

"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," he said; "but that He might be made manifest to Israel, therefore came I baptizing with water." Give heed for a little, beloved. When did John learn Christ? For he was sent to baptize with water. They asked, Wherefore? That He might be made manifest to Israel, he said. Of what profit was the baptism of John? My brethren, if it had profited in any respect, it would have remained now, and men would have been baptized with the baptism of John, and thus have come to the baptism of Christ. But what saith he? "That He might be made manifest to Israel,"--that is, to Israel itself, to the people Israel, so that Christ might be made manifest to it,--therefore he came baptizing with water. John received the ministry of baptism, that by the water of repentance he might prepare the way for the Lord, not being himself the Lord; but where the Lord was known, it was superfluous to prepare for Him the way, for to those who knew Him He became Himself the way; therefore the baptism of John did not last long. But how was the Lord pointed out? Lowly, that John might so receive a baptism in which the Lord Himself should be baptized. And was it needful for the Lord to be baptized? I instantly reply to any one who asks this question: Was it needful for the Lord to be born? Was it needful for the Lord to be crucified? Was it needful for the Lord to die? Was it needful for the Lord to be buried? If He undertook for us so great humiliation, might He not also receive baptism? And what profit was there that he received the baptism of a servant? That thou mightest not disdain to receive the baptism of the Lord. Give heed, beloved brethren. Certain catechumens were to arise in the Church of higher grace. It sometimes comes to pass that you see a catechumen who practises continence, bids farewell to the world, renounces all his possessions, distributing them to the poor; and although but a catechumen, instructed in the saving doctrine better, perhaps, than many of the faithful. It is to be feared regarding such an one that he may say to himself about holy baptism, whereby sins are remitted, What more shall I receive? Behold, I am better than this faithful man, and this,--having in his mind those among the faithful who are either married, or who are perhaps ignorant, or who keep possession of their property, while he has given his to the poor,--and considering himself better than those who have been already baptized, he deigns not to come to baptism, saying, Am I to receive what this man has, and this thinking of persons whom he despises, and, as it were, considers it an indignity to receive that which inferiors have received, because he appears to himself to be already better than they; and, nevertheless, all his sins are upon him, and without coming to saving baptism, wherein all sins are remitted, he cannot, with all his excellence, enter into the kingdom of heaven. But the Lord, in order to invite such excellence to his baptism, that sins might be remitted, Himself came to the baptism of His servant; and although He had no sin to be remitted, nor was there anything in Him that needed to be washed, He received baptism from a servant; and by so doing, addressed Himself to the son carrying himself proudly, and exalting himself, and disdaining, perhaps, to receive along with the ignorant that from which salvation comes to him, and said to him: How dost thou extend thyself? How dost thou exalt thyself? How great is thy excellence? How great is thy grace? Can it be greater than mine? If I come to the servant, dost thou disdain to come to the Lord? If I have received the baptism of the servant, dost thou disdain to be baptized by the Lord?

(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.
