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.

11. (1Co 11:18).

by them … of … house of Chloe—They seem to have been alike in the confidence of Paul and of the Corinthians. The Corinthians "wrote" to the apostle (1Co 7:1), consulting him concerning certain points; marriage, the eating of things offered to idols, the decorum to be observed by women in religious assemblies. But they said not a syllable about the enormities and disorders that had crept in among them. That information reached Paul by other quarters. Hence his language about those evils is, "It hath been declared unto me," &c.; "It is reported commonly" (1Co 5:1, 2). All this he says before he refers to their letter, which shows that the latter did not give him any intimation of those evils. An undesigned proof of genuineness [Paley, Horæ Paulinæ]. Observe his prudence: He names the family, to let it be seen that he made his allegation not without authority: he does not name the individuals, not to excite odium against them. He tacitly implies that the information ought rather to have come to him directly from their presbyters, as they had consulted him about matters of less moment.

contentions—not so severe a word as "divisions," literally, "schisms" (1Co 1:10, Margin).
