(15) Is Christ divided? was (16) Paul crucified for you? or were ye (17) baptized in the name of Paul?
(15) The first reason why divisions ought to be avoided: because Christ seems by that means to be divide and torn in pieces, who cannot be the head of two different and disagreeing bodies, being himself one.
(16) Another reason: because they cannot without great injury to God so depend on men as on Christ: which thing those no doubt do who allow whatever some man speaks, and do it for their own sakes: as these men allowed one and the very same Gospel being uttered by one man, and did loathe it being uttered by another man. So that these factions were called by the names of their teachers. Now Paul sets aside his own name, not simply to grieve no man, but also to show that he does not plead his own cause.
(17) The third reason taken from the form and end of baptism, in which we make a promise to Christ, calling also on the name of the Father, and the Holy Spirit. Therefore although a man does not fall from the doctrine of Christ, yet if he depends upon certain teachers, and despises others, he forsakes Christ: for if he holds Christ as his only master, he would hear him, no matter who Christ taught by.
