1 Corinthians 11:17-19

17Now I must teach you about something else about your meetings. I will not praise you, because more bad things than good things happen when you meet together.

18First, I hear that there are separate groups when you meet together as God's people. I believe that some of what I have heard about you is true.

19Perhaps there must be separate groups among you. Then everyone can see clearly which group God accepts as right!
