In my sermon on 1 Corinthians 6:1-11, I had mentioned the problem of improper judging which the Corinthian believers were engaging in. The solution to the problem of improper judging, of which suing other believer in court over trivial matters is one such manifestation (not the only manifestation) is to deal with conflicts within the church, with formal church courts being the final means of mediation and arbitration of conflicts. The first step of dealing with conflicts is to engage in the procedure laid out by Jesus in Matthew 18:15-17, which states:
“If your brother sins against you, go and tell him his fault, between you and him alone. If he listens to you, you have gained your brother. But if he does not listen, take one or two others along with you, that every charge may be established by the evidence of two or three witnesses. If he refuses to listen to them, tell it to the church. And if he refuses to listen even to the church, let him be to you as a Gentile and a tax collector.
The first step is to approach the person who has offended you, personally, one on one. The next step is to take two or three other believers to arbitrate the conflict (not to gang up on the offender). Only if that fails then formal church proceedings can take place ("tell it to the church"). That is the process which Jesus set up, and which we should rightly follow.
Now, I confess that I am not faultless in violating this process. It is very easy when you have something against your brother (or sister) to gossip behind their backs. And it is very easy to desire to have the offender punished then to be reconciled to your brother. So I am most certainly not saying this because I have already arrived. In fact, far from it. But this is what God's Word teaches, and I myself have to endeavor to submit to it. Where I have fallen, I must repent.
The sad reality is that improper judging, much more frequently than wrong doctrine, causes much conflict within the church. While we must correct wrong doctrine, it is also imperative on us who name the name of Christ to also strive to deal with our interpersonal issues in a way that glorifies our Lord and Savior Jesus Christ. Is anyone of us faultless in this? I doubt it. But speaking as one who has failed in this many times, let us not be comfortable with our failures but to strive to do better. Because the fact of the matter is that we are already saved. We are already washed with the waters of regeneration in baptism, we are already set apart by God to be holy, and we are already justified and stand guiltless before God (1 Cor. 6:11). Therefore, we can and must work on our walk with God and with each other in the community of faith, in the constant struggle of seeking holiness before God.
