1 Corinthians 11:16-19

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

17Now in this that I declare unto 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 be divisions among you; and I partly believe it.

19For there must be also heresies among you, that they which are approved may be made manifest among you.
