Rushdoony on the State

Thus the true church in every age has a mission to the state, to proclaim the fall of Babylon, to declare to the state that civil government can endure only under God and in obedience to His word, that every attempt of civil government to become as god, to be the purveyor of grace and of paradise, is damned and doomed. The cleansing of civil government and the indictment of it by the word must be the task of the church in every age.
