He told church members not to take each other into civil courts run by and for covenant-breakers. He also told them that covenant-breakers cannot escape from God's revelation of Himself and the work of His law. This is a blessing of common grace. This common revelation of God and the work of God's law in every human heart are the biblical epistemological foundations of political and judicial assessments regarding social justice and social utility. Were it not for the image of God in man, including the work of God's law, the methodological individualist could not logically say that civil judges or voters can accurately aggregate individual utilities or values in their attempt to derive both a concept of social utility and a workable application of it to specific cases.
Social cooperation requires a shared discourse.
Without this, society would disintegrate in the war of all against all. Original sin and total depravity would undermine society. God's common grace prevents this outcome. Without the division of labor, there could be no fulfillment of the dominion covenant. The command was given to all men.
