1 Corinthians 6:1-7

Furthermore, how dare you take a fellow believer to court! It is wrong to drag him before the unrighteous to settle a legal dispute. Isn’t it better to take him before God’s holy believers to settle the matter? Don’t you realize that we, the holy ones, will judge the universe? If the unbelieving world is under your jurisdiction, you should be fully competent to settle these trivial lawsuits among yourselves. For surely you know that we will one day judge angels, let alone these everyday matters. Don’t you realize that you are bringing your issues before civil judges appointed by people who have no standing within the church? What a shame that there is not one within the church who has the spirit of wisdom who could arbitrate these disputes and reconcile the offended parties! It’s not right for a believer to sue a fellow believer—and especially to bring it before the unbelievers. Don’t you realize that when you drag another believer into court you’re providing the evidence that you are already defeated? Wouldn’t it be better to accept the fact that someone is trying to cheat and take advantage of you, and simply choose the high road? At times it is better to just accept injustice and even to let someone take advantage of you, rather than to expose our conflicts publicly before unbelievers.
