Paul rebukes the sects, and authors of sects. Christ is the foundation of his church. We must take heed how we build on this foundation. No one ought to glory in men, but in God.

3 And I could not speak to you brethren as to spiritual people, but as to carnal; even, as it were, to babes in Christ. ² I gave you milk to drink, and not meat. For you were not strong then, no, neither are you yet.
