1 Corinthians 11:16-19

16But if any one think to be contentious, we have no such custom, nor the assemblies of 1God.

17But [in] prescribing [to you on] this [which I now enter on], I do not praise, [namely,] that ye come together, not for the better, but for the worse.

18For first, when ye come together in assembly, I hear there exist divisions among you, and I partly give credit [to it].

19For there must also be sects among you, that the approved may become manifest among you.
