97 Petilianus said: "And, again, he taught us that schisms should not arise, in the following terms: ‘Now this I say, that every one of you says, I am of Paul, and I of Apollos, and I of Cephas, and I of Christ. Is Christ divided? Was Paul crucified for you? Or were ye baptized in the name of Paul?'"
98. Augustine answered: Remember all of you who read this, it was Petilianus who quoted these words from the apostle. For who could have believed that he would have brought forward words which tell so much for us against himself?
