I have personally experienced this attitude inside my former church and even have friends now who are being tormented by their fellow believers all in the name of Jesus. How sick it is and how sick they remain.
1 Corinthians 6:1-7
If any of you has a dispute with another, dare he take it before the ungodly for judgment instead of before the saints? Do you not know that the saints will judge the world? And if you are to judge the world, are you not competent to judge trivial cases? Do you not know that we will judge angels? How much more the things of this life! Therefore, if you have disputes about such matters, appoint as judges even men of little account in the church! I say this to shame you. Is it possible that there is nobody among you wise enough to judge a dispute between believers? But instead, one brother goes to law against another—and this in front of unbelievers! The very fact that you have lawsuits among you means you have been completely defeated already. Why not rather be wronged? Why not rather be cheated?
