"To be a Christian is to be subversive, or at least that is how he will be viewed by society. Since his loyalty is to one who is beyond history, he cannot give his ultimate allegiance to any government, business, class, or any other institution. His views cannot be expected to coincide with the majority view around him. He can be expected to be in continual conflict with the structures of society, for to be at peace with God means to be in conflict with the world."
