1 Corinthians 1:9-12

God is faithful, through whom ye were called into the fellowship of his Son Jesus Christ our Lord. Now I beseech you, brethren, through the name of our Lord Jesus Christ, that ye all speak the same thing, and that there be no divisions among you; but that ye be perfected together in the same mind and in the same judgment. For it hath been signified unto me concerning you, my brethren, by them that are of the household of Chloe, that there are contentions among you. Now this I mean, that each one of you saith, I am of Paul; and I of Apollos; and I of Cephas; and I of Christ.
