1 Corinthians 11:16-19
English Standard Version
Chapter 11
16If anyone is inclined to be contentious, we have no such practice, nor do the churches of God.
17But in the following instructions I do not commend you, because when you come together it is not for the better but for the worse.
18For, in the first place, when you come together as a church, I hear that there are divisions among you. And I believe it in part,
19for there must be factions among you in order that those who are genuine among you may be recognized.
