1:10-16 In the great things of religion be of one mind; and where there is not unity of sentiment, still let there be union of affection. Agreement in the greater things should extinguish divisions about the lesser. There will be perfect union in heaven, and the nearer we approach it on earth, the nearer we come to perfection. Paul and Apollos both were faithful ministers of Jesus Christ, and helpers of their faith and joy; but those disposed to be contentious, broke into parties. So liable are the best things to be corrupted, and the gospel and its institutions made engines of discord and contention. Satan has always endeavoured to stir up strife among Christians, as one of his chief devices against the gospel. The apostle left it to other ministers to baptize, while he preached the gospel, as a more useful work.
12. this I say—this is what I mean in saying "contentions" (1Co 1:11).
every one of you saith—Ye say severally, "glorying in men" (1Co 1:31; 1Co 3:21, 22), one, I am of Paul; another, I am of Apollos, &c. Not that they formed definite parties, but they individually betrayed the spirit of party in contentions under the name of different favorite teachers. Paul will not allow himself to be flattered even by those who made his name their party cry, so as to connive at the dishonor thereby done to Christ. These probably were converted under his ministry. Those alleging the name of Apollos, Paul's successor at Corinth (Ac 18:24, &c.), were persons attracted by his rhetorical style (probably acquired in Alexandria, 1Co 3:6), as contrasted with the "weak bodily presence" and "contemptible speech" of the apostle. Apollos, doubtless, did not willingly foster this spirit of undue preference (1Co 4:6, 8); nay, to discourage it, he would not repeat his visit just then (1Co 16:12).
I of Cephas—probably Judaizers, who sheltered themselves under the name of Peter, the apostle of the circumcision ("Cephas" is the Hebrew, "Peter" the Greek name; Joh 1:42; Ga 2:11, &c.): the subjects handled in the seventh through ninth chapters were probably suggested as matters of doubt by them. The church there began from the Jewish synagogue, Crispus the chief ruler, and Sosthenes his successor (probably), being converts. Hence some Jewish leaven, though not so much as elsewhere, is traceable (2Co 11:22). Petrism afterwards sprang up much more rankly at Rome. If it be wrong to boast "I am of Peter," how much more so to boast I am of the Pope!" [Bengel].
I of Christ—A fair pretext used to slight the ministry of Paul and their other teachers (1Co 4:8; 2Co 10:7-11).
