Evangelical elites tell us that Christian nationalism and theocracy are grave dangers to our Christian witness and the "neutral public square." But the real danger is secularism itself. In *Mere Christendom*, Douglas Wilson takes aim at the fundamental assumption of secularism: the idea that government can be morally and religiously neutral, extending tolerance to everyone and persecuting no one. Every nation has its religion, and the only question is whether we have a good nation that rewards the righteousness or a wicked one that punishes it. This book is not a call to put pastors in the White House. Instead, it is a scriptural case for taking your private faith and bringing it into the public square.
