John Chrysostom, on 1Cor 1:12

“Now this I say, that every one of you saith: I indeed am of Paul; and I am of Apollo; and I am of Cephas; and I of Christ.”

“Next he declares also the kind of contention. "That each one of you saith, I am of Paul, and I of Apollos, and I of Cephas." "I say, contentions," saith he, "I mean, not about private matters, but of the more grievous sort, of the Church. And yet they were not speaking about himself, nor about Peter, nor about Apollos; but he signifies that if these were not to be leaned on, much less others. For that they had not spoken about them, he saith further on: "And these things I have transferred in a figure unto myself and Apollos, that ye may learn in us not to go beyond the things which are written." For if it were not right for them to call themselves by the name of Paul, and of Apollos, and of Cephas, much less of any others. If under the Teacher and the first of the Apostles, and one that had instructed so much people, it were not right to enroll themselves, much less under those who were nothing. By way of hyperbole then, seeking to withdraw them from their disease, he sets down these names. Besides, he makes his argument less severe, not mentioning by name the rude dividers of the Church, but concealing them, as behind a sort of masks, with the names of the Apostles. "I am of Paul, and I of Apollos, and I of Cephas." Not esteeming himself before Peter hath he set his name last, but preferring Peter to himself, and that greatly. He arranged his statement in the way of climax, that he might not be supposed to do this for attack, and then mentions Apollos, and then Cephas. Not therefore to magnify himself did he do this, but in speaking of wrong things he administers the requisite correction in his own person first. But that those who addicted themselves to this or that man were in error, is evident. And rightly he rebukes them, saying, "Ye do not well in that ye say, 'I am of Paul, and I of Apollos, and I of Cephas.'" But why did he add, "And I of Christ?" For although those who addicted themselves to men were in error, not surely those who dedicated themselves unto Christ. But this was not his charge, that they called themselves by the Name of Christ, but that they did not all call themselves by that Name alone. And I think that he added this of himself, wishing to make the accusation more grievous, and to point out that by this rule Christ must be considered as belonging to one party only: although they were not so using the Name themselves. For that this was what he hinted at he declared in the sequel.”
