1 Corinthians 11:16-19

Thomson(i) 16 If any one, however, is disposed to be contentious, neither we nor the congregations have any such custom. 17 But in regard to this which I am about to mention I do not commend you, because you meet together not for the better but for the worse. 18 For in the first place, on your assembling together in the congregation, I hear that there are divisions among you; and I partly believe it: 19 for there must be sects among you, that the approved among you may become manifest.
