Of all Christian writers, the philosopher Hobbes alone has seen the evil and how to remedy it, and has dared to propose the reunion of the two heads of the eagle, and the restoration throughout of political unity, without which no State or government will ever be rightly constituted. But he should have seen that the masterful spirit of Christianity is incompatible with his system, and that the priestly interest would always be stronger than that of the State. It is not so much what is false and terrible in his political theory, as what is just and true, that has drawn down hatred on it.[4] I believe that if the study of history were developed from this point of view, it would be easy to refute the contrary opinions of Bayle and Warburton, one of whom holds that religion can be of no use to the body politic, while the other, on the contrary, maintains that Christianity is its strongest support. We should demonstrate to the former that no State has ever been founded without a religious basis, and to the latter, that the law of Christianity at bottom does more harm by weakening than good by strengthening the constitution of the State. To make myself understood, I have only to make a little more exact the too vague ideas of religion as relating to this subject. Religion, considered in relation to society, which is either general or particular, may also be divided into two kinds: the religion of man, and that of the citizen. The first, which has neither temples, nor altars, nor rites, and is confined to the purely internal cult of the supreme God and the eternal obligations of morality, is the religion of the Gospel pure and simple, the true theism, what may be called natural divine right or law. The other, which is codified in a single country, gives it its gods, its own tutelary patrons; it has its dogmas, its rites, and its external cult prescribed by law; outside the single nation that follows it, all the world is in its sight infidel, foreign and barbarous; the duties and rights of man extend for it only as far as its own altars. Of this kind were all the religions of early peoples, which we may define as civil or positive divine right or law. There is a third sort of religion of a more singular kind, which gives men two codes of legislation, two rulers, and two countries, renders them subject to contradictory duties, and makes it impossible for them to be faithful both to religion and to citizenship. Such are the religions of the Lamas and of the Japanese, and such is Roman Christianity, which may be called the religion of the priest. It leads to a sort of mixed and anti-social code which has no name. In their political aspect, all these three kinds of religion have their defects. The third is so clearly bad, that it is waste of time to stop to prove it such. All that destroys social unity is worthless; all institutions that set man in contradiction to himself are worthless.
