1 Corinthians 6:1-4 New Revised Standard Version (NRSV)
Lawsuits among Believers
6 When any of you has a grievance against another, do you dare to take it to court before the unrighteous, instead of taking it before 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—to say nothing of ordinary matters? 4 If you have ordinary cases, then, do you appoint as judges those who have no standing in the church?
