If any one should enquire, "And in what was the baptism of the disciples better than that of John?" we will reply, "in nothing"; both were alike without the gift of the Spirit, both parties alike had one reason for baptizing, and that was, to lead the baptized to Christ. For in order that they might not be always running about to bring together those that should believe, as in Simon's case his brother did, and Philip to Nathanael, they instituted baptism, in order by it to bring all men to them easily, and to prepare a way for the faith which was to be. But that the baptisms had no superiority one over the other, is shown by what follows.
"There arose," saith the Evangelist, "a question (between some) of John's disciples and the Jews about purifying."
For the disciples of John being ever jealously disposed towards Christ's disciples and Christ Himself, when they saw them baptizing, began to reason with those who were baptized, as though their baptism was in a manner superior to that of Christ's disciples; and taking one of the baptized, they tried to persuade him of this; but persuaded him not. Hear how the Evangelist has given us to understand that it was they who attacked him, not he who set on foot the question. He doth not say, that "a certain Jew questioned with them," but that, "there arose a questioning from the disciples of John with a certain Jew, concerning purification."
(Hom. xx. 1) But why did he go on baptizing now? Because, had he left off, it might have been attributed to envy or anger: whereas, continuing to baptize, he got no glory for himself, but sent hearers to Christ. And he was better able to do this service, than were Christ's own disciples; his testimony being so free from suspicion, and his reputation with the people so much higher than theirs. He therefore continued to baptize, that he might not increase the envy felt by his disciples against our Lord's baptism. Indeed, the reason, I think, why John's death was permitted, and, in his room, Christ made the great preacher, was, that the people might transfer their affections wholly to Christ, and no longer be divided between the two. For the disciples of John did become so envious of Christ's disciples, and even of Christ Himself, that when they saw the latter baptizing, they threw contempt upon their baptism, as being inferior to that of John's; And there arose a question from some of John's disciples with the Jews about purifying. That it was they who began the dispute, and not the Jews, the Evangelist implies by saying, that there arose a question from John's disciples, whereas he might have said, The Jews put forth a question.
"Then there arose a question on the part of John's disciples with the Jews about purifying." John baptized, Christ baptized. John's disciples were moved; there was a running after Christ, people were coming to John. Those who came to John, he sent to Jesus to be baptized; but they who were baptized by Christ were not sent to John. John's disciples were alarmed, and began to dispute with the Jews, as usually happens. Understand the Jews to have declared that Christ was greater, and that to His baptism people ought to have recourse. John's disciples, not yet understanding this, defended John's baptism. They came to John himself, that he might solve the question. Understand, beloved. And here we are given to see the use of humility, and, when people were erring in the subject of dispute, are shown whether John desired to glory in himself. Now probably he said, "You say the truth, you contend rightly; mine is the better baptism, I baptized Christ Himself." John could say this after Christ was baptized. If he wished to exalt himself, what an opportunity he had to do so! But he knew better before whom to humble himself: to Him whom he knew to have come after himself by birth, he willingly yielded precedence by confessing Him. He understood his own salvation to be in Christ. He had already said above, "We all have received out of His fullness;" and this is to confess Him to be God. For how can all men receive of His fullness, if He be not God? For if He is man in such wise that He is not God, then Himself also receives of the fullness of God, and so is not God. But if all men receive of His fullness, He is the fountain, they are drinkers. They that drink of a fountain, both thirst and drink. The fountain never thirsts; it has never need of itself. Men need a fountain. With thirsty stomachs and parched lips they run to the fountain to be refreshed. The fountain flows to refresh, so does the Lord Jesus.
The Jews being powerless to commend the purifications of the law, and not able to advocate the cleansing through the ashes of an heifer, plan something against John's disciples, whereby they thought to cause them no slight vexation, albeit easily worsted in their own matters. For since they who attended the blessed Baptist, appeared to be more excellent and of more understanding than the Pharisees, admiring the baptism of their own teacher, and opposing the purifications after the law; they are vexed at these things, who are diligent in reviling only and most ready unto all wickedness: and even overturning their own case, they praise Christ's Baptism, not rightly disposed, nor pouring forth true praise on it, but exasperated to the mere distressing of them; and lending out a statement against their opinion, until their purpose should attain its accomplishment. They cannot then adduce any reasonable proof, nor do they even support Christ out of the holy Scriptures (for, whence were such understanding to the uninstructed?): but they merely allege in confirmation of their own arguments, that very few in number are those who come to John, but that they flock together to Christ. For haply they in their exceeding folly thought that they should carry off the vote of victory, and might speak out in behalf of the legal purifications, as having already conquered, by giving the palm over John's to the Baptism bestowed by Christ on those who come to Him. And they vex those with whom their dispute was: but they get off with difficulty and leave the disciples of John, much more beaten by their ill-considered dispute. For they crown with compulsory praises, and against their will, the Lord.
