"I say this to your shame. Can it be that there is no one among you wise enough to settle a dispute between the brothers, but brother goes to law against brother, and that before unbelievers? To have lawsuits at all with one another is already a defeat for you. Why not rather suffer wrong? Why not rather be defrauded?"
I always think of this 1 Corinthians passage whenever I hear that a congregation member is suing another member or their church. If they truly believe their book, they'll be willing to risk suffering and handle the situation within the church, trusting that their God will provide the right solution. But so often that doesn't happen - when the rubber meets the road, they turn to the secular justice system, knowing that if they don't, they'll get screwed.
