1 Corinthians 6:1-6 RSV

1 When one of you has a grievance against a brother, does he dare go to law before the unrighteous instead of the saints?
2 Do you not know that the saints will judge the world? And if the world is to be judged by you, are you incompetent to try trivial cases?
3 Do you not know that we are to judge angels? How much more, matters pertaining to this life!
4 If then you have such cases, why do you lay them before those who are least esteemed by the church?
5 I say this to your shame. Can it be that there is no man among you wise enough to decide between members of the brotherhood,
6 but brother goes to law against brother, and that before unbelievers?
