But I am mistaken in speaking of a Christian republic; the terms are mutually exclusive. Christianity preaches only servitude and dependence. Its spirit is so favourable to tyranny that it always profits by such a _régime_. True Christians are made to be slaves, and they know it and do not much mind: this short life counts for too little in their eyes. I shall be told that Christian troops are excellent. I deny it. Show me an instance. For my part, I know of no Christian troops. I shall be told of the Crusades. Without disputing the valour of the Crusaders, I answer that, so far from being Christians, they were the priests' soldiery, citizens of the Church. They fought for their spiritual country, which the Church had, somehow or other, made temporal. Well understood, this goes back to paganism: as the Gospel sets up no national religion, a holy war is impossible among Christians. Under the pagan emperors, the Christian soldiers were brave; every Christian writer affirms it, and I believe it: it was a case of honourable emulation of the pagan troops. As soon as the emperors were Christian, this emulation no longer existed, and, when the Cross had driven out the eagle, Roman valour wholly disappeared. But, setting aside political considerations, let us come back to what is right, and settle our principles on this important point. The right which the social compact gives the Sovereign over the subjects does not, we have seen, exceed the limits of public expediency.[5] The subjects then owe the Sovereign an account of their opinions only to such an extent as they matter to the community. Now, it matters very much to the community that each citizen should have a religion. That will make him love his duty; but the dogmas of that religion concern the State and its members only so far as they have reference to morality and to the duties which he who professes them is bound to do to others. Each man may have, over and above, what opinions he pleases, without it being the Sovereign's business to take cognisance of them; for, as the Sovereign has no authority in the other world, whatever the lot of its subjects may be in the life to come, that is not its business, provided they are good citizens in this life. There is therefore a purely civil profession of faith of which the Sovereign should fix the articles, not exactly as religious dogmas, but as social sentiments without which a man cannot be a good citizen or a faithful subject.[6] While it can compel no one to believe them, it can banish from the State whoever does not believe them--it can banish him, not for impiety, but as an anti-social being, incapable of truly loving the laws and justice, and of sacrificing, at need, his life to his duty. If any one, after publicly recognising these dogmas, behaves as if he does not believe them, let him be punished by death: he has committed the worst of all crimes, that of lying before the law.
