I Corinthians 1:10-13, 30-31

Now I plead with you, brethren, by the name of our Lord Jesus Christ, that you all speak the same thing, and that there be no divisions among you, but that you be perfectly joined together in the same mind and in the same judgment. For it has been declared to me concerning you, my brethren, by those of Chloe’s household, that there are contentions among you. Now I say this, that each of you says, “I am of Paul,” or “I am of Apollos,” or “I am of Cephas,” or “I am of Christ.” Is Christ divided? Was Paul crucified for you? Or were you baptized in the name of Paul?

But of Him you are in Christ Jesus, who became for us wisdom from God—and righteousness and sanctification and redemption— that, as it is written, “He who glories, let him glory in the LORD.”
