“When one of you has a dispute with another believer, how dare you file a lawsuit and ask a secular court to decide the matter instead of taking it to other believers! Don’t you realize that someday we believers will judge the world? And since you are going to judge the world, can’t you decide even these little things among yourselves?” 1 Corinthians 6:1-2
Paul is dealing with a problem which specially affected the Greeks. The Jews did not ordinarily go to law in the public law courts at all; they settled things before the elders of the village or the elders of the synagogue; to them justice was far more a thing to be settled in a family spirit than in a legal spirit. The Jewish law expressly forbade a Jew to go to law at all in a non-Jewish court; to do so was considered blasphemy against the divine law of God.
Paul is not saying that Christians should not go to the law. If Christians did not use the law, they would suffer great loss at the hands of the unsaved. He is saying that Christians should not go to the law against each other. The differences between believers are not to be taken to secular court. It affects our Christian witness.
What made the matter still more fantastic to Paul was that, in the picture of the golden age to come, the Messiah was to judge the nations and the saints were to share in that judgment. So, Paul demands, “If some day you are going to judge the world, if even the angels, the highest created beings, are going to be subject to your judgment, how, in the name of all that is reasonable, can you go and submit your cases to men and to heathen men at that?” “If you must do it,” he says, “do it inside the Church, and give the task of judging to the people of whom you think least, for no man who is destined to judge the world could possibly be bothered getting himself involved in petty everyday squabbles.”
