1 Corinthians 11:16-19

ERV(i) 16 But if any man seemeth to be contentious, we have no such custom, neither the churches of God. 17 But in giving you this charge, I praise you not, that ye come together not for the better but for the worse. 18 For first of all, when ye come together in the church, I hear that divisions exist among you; and I partly believe it. 19 For there must be also heresies among you, that they which are approved may be made manifest among you.
