1 Corinthians 11:16-19

16But if any man seemeth to be contentious, we have no such custom, neither the churches of God.

17Now in this that I declare to you I praise you not, that ye come together not for the better, but for the worse. 18For first of all, when ye come together in the church, I hear that there are divisions among you; and I partly believe it.1 19For there must be also heresies among you, that they who are approved may be become evident among you.2
