I thank my God. In these words he reproves very sharply the perversity of the Corinthians, which made it necessary for him to avoid, in a manner, a thing so sacred and honorable as that of the administration of baptism. Paul, indeed, would have acted with propriety, and in accordance with the nature of his office, though he had baptized ever so many. He rejoices, however, that it had happened otherwise, and acknowledges it as having been so ordered, in the providence of God, that they might not take occasion from that to glory in him, or that he might not bear any resemblance to those ambitious men who endeavored in this way to catch followers. But what if he had baptized many? There would have been no harm in it, but (as I have said) there is couched under this a heavy reproach against the Corinthians and their false apostles, inasmuch as a servant of the Lord found occasion to rejoice that he had refrained from a work, otherwise good and commendable, lest it should become an occasion of harm to them.

I thank God - Why Paul did not himself baptize, see in 1-Corinthians 1:17. To him it was now a subject of grateful reflection that he had not done it. He had not given any occasion for the suspicion that he had intended to set himself up as a leader of a sect or party.
But Crispus - Crispus had been the chief ruler of the synagogue at Corinth; Acts 18:8.
And Gaius - Gaius resided at Corinth, and at his house Paul resided when he wrote the Epistle to the Romans; Romans 16:23. It is also possible that the Third Epistle of John was directed to this man; see 3-John 1:1. And if so, then probably Diotrephes 3-John 1:9, who is mentioned as one who loved "to have the pre-eminence," had been one cause of the difficulties at Corinth. The other persons at Corinth had been probably baptized by Silas and Timothy.

I thank God that I baptized none of you - None of those who now live in Corinth, except Crispus, the ruler of the synagogue, Acts 18:8. And Gaius, the same person probably with whom Paul lodged, Romans 16:23 (note). Dr. Lightfoot observes: "If this be Gaius, or Caius, to whom the third epistle of John was written, which is very probable when the first verse of that epistle (3-John 1:1) is compared with Romans 16:23, then it will appear probable that John wrote his first epistle to the Corinthians. I wrote, says he, unto the Church - What Church? Certainly it must have been some particular Church which the apostle has in view, and the Church where Gaius himself resided. And if this be true, we may look for Diotrephes (3-John 1:9) in the Corinthian Church; and the author of the schism of which the apostle complains. See the Introduction, Section 8.

(18) I thank God that I baptized none of you, but Crispus and Gaius;
(18) He protests that he speaks so much the more boldly of these things, because through God's providence, he is void of all suspicion of gathering disciples to himself, and taking them from others. By which we may understand, that not the scholars only, but the teachers also are here reprehended, who gathered flocks separately and for themselves.

I thank God that I baptized none of you,.... The Alexandrian copy and the Syriac version read, "I thank my God"; not that the apostle disliked the ordinance of baptism, or the administration of it; and much less that he thought it criminal, or an evil in him to perform it; nor was he at any time displeased at the numbers of persons who desired it of him; but on the contrary rejoiced where proper subjects of it were brought to a submission to it; but inasmuch as some persons in the church at Corinth made such an ill use of his having baptized them, he was greatly thankful that it was so ordered in providence, that the far greater part of them were baptized by other ministers, either by those who were with him, or came after him; and that he baptized none of them with his own hands,
but Crispus and Gaius. The former of these was the chief ruler of the Jewish synagogue at Corinth, who hearing the apostle, and believing in Christ, was baptized by him, Acts 18:8 and the latter was a very liberal and hospitable man, and was the apostle's host, whilst he was at Corinth; see Romans 16:23.

I thank God's providence now, who so ordered it that I baptized none of you but Crispus (the former ruler of the synagogue, Acts 18:8) and Gaius (written by the Romans Caius, the host of Paul at Corinth, and of the church, Romans 16:23; a person therefore in good circumstances). Baptizing was the office of the deacons (Acts 10:48) rather than of the apostles, whose office was that of establishing and superintending generally the churches. The deacons had a better opportunity of giving the necessary course of instruction preparatory to baptism. Crispus and Gaius were probably among the first converts, and hence were baptized by Paul himself, who founded the church.

I thank God - (A pious phrase for the common one, "I rejoice,") that, in the course of his providence, I baptized none of you, but Crispus, once the ruler of the synagogue, and Caius.
