1 Corinthians 11:17-20 New King James Version (NKJV)

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

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

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

20. Therefore when you come together in one place, it is not to eat the Lord’s Supper.
