Theophylact of Ohrid, 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.”

“Not some say this, but "among you." The Corinthians, however, did not actually say this, but the apostle gives such a turn of phrase, wishing to show that if it is unforgivable to call oneself followers of Paul and of Cephas, then all the more so of the names of others. "I am of Cephas." He mentioned Peter after himself not in order to exalt himself, but showing him greater preference, just as he mentioned Christ after. In general, in matters that ought not to be, he mentions his own person first. "And I am of Christ." He does not reproach them for saying "I am of Christ," but for the fact that not all say this; or rather, he added this on his own, wishing to make the rebuke stronger and to show that in such a case even Christ is appropriated by one party, although the Corinthians did not actually do this.”
