Christian people need to be engaged in political life while being able to convincingly deny any aspirations of theocracy. Of course we want to “legislate morality”. Everybody does. The transcendent source of our moral values should not disqualify us. But the morality that we want to legislate must be the moral principles of creation ethics. So it is surely necessary to be involved in legal issues of life and death, marriage and family, environment, economics and truth telling. But I have little sympathy for trying to force prayer to God into public schools against people that don’t want it.
