1 Corinthians 11:16-19

16But if anyone seems to be contentious, we have no such custom, nor do the churches of God.

17Now in giving these instructions I do not praise you, since you come together not for the better but for the worse.

18For first of all, when you come together as a church, I hear that there are divisions among you, and in part I believe it.

19For there must also be factions among you, that those who are approved may be recognized among you.
