And the same principles of priestly government continuing, after Christianity became the established religion; they have engendered a spirit of persecution, which has ever since been the poison of human society, and the source of the most inveterate factions in every government. Such divisions, therefore, on the part of the people, may justly be esteemed factions of principle; but, on the part of the priests, who are the prime movers, they are really factions of interest.
There is another cause (beside the authority of the priests, and the separation of the ecclesiastical and civil powers) which has contributed to render Christendom the scene of religious wars and divisions. Religions, that arise in ages totally ignorant and barbarous, consist mostly of traditional tales and fictions, which may be different in every sect, without being contrary to each other: and even when they are contrary, every one adheres to the tradition of his own sect, without much reasoning or disputation. But as philosophy was widely spread over the world, at the time when Christianity arose, the teachers of the new sect were obliged to form a system of speculative opinions; to divide, with some accuracy, their articles of faith; and to explain, comment, confute, and defend with all the subtlety of argument and science. Hence naturally arose keenness in dispute, when the Christian religion came to be split into new divisions and heresies: And this keenness assisted the priests in their policy, of begetting a mutual hatred and antipathy among their deluded followers. Sects of philosophy, in the ancient world, were more zealous than parties of religion; but, in modern times, parties of religion are more furious and enraged than the most cruel factions that ever arose from, interest and ambition.
