When Christianity began to penetrate into Gaul, it encountered there two religions very different one from the other, and infinitely more different from the Christian religion; these were Druidism and paganism--hostile one to the other, but with a hostility political only, and unconnected with those really religious questions that Christianity was coming to raise. Druidism, considered as a religion, was a mass of confusion, wherein the instinctive notions of the human race concerning the origin and destiny of the world and of mankind were mingled with the oriental dreams of metempsychosis--that pretended transmigration, at successive periods, of immortal souls into divers creatures. This confusion was worse confounded by traditions borrowed from the mythologies of the East and the North, by shadowy remnants of a symbolical worship paid to the material forces of nature, and by barbaric practices, such as human sacrifices, in honor of the gods or of the dead. People who are without the scientific development of language and the art of writing do not attain to systematic and productive religious creeds. There is nothing to show that, from the first appearance of the Gauls in history to their struggle with victorious Rome, the religious influence of Druidism had caused any notable progress to be made in Gallic manners and civilization. A general and strong, but vague and incoherent, belief in the immortality of the soul was its noblest characteristic. But with the religious elements, at the same time coarse and mystical, were united two facts of importance: the Druids formed a veritable ecclesiastical corporation, which had, throughout Gallic society, fixed attributes, special manners and customs, an existence at the same time distinct and national; and in the wars with Rome this corporation became the most faithful representatives and the most persistent defenders of Gallic independence and nationality. The Druids were far more a clergy than Druidism was a religion; but it was an organized and a patriotic clergy. It was especially on this account that they exercised in Gaul an influence which was still existent, particularly in Northwestern Gaul, at the time when Christianity reached the Gallic provinces of the South and Centre. The Græco-Roman paganism was, at this time, far more powerful than Druidism in Gaul, and yet more lukewarm and destitute of all religious vitality. It was the religion of the conquerors and of the State, and was invested, in that quality, with real power; but, beyond that, it had but the power derived from popular customs and superstitions. As a religious creed, the Latin paganism was at bottom empty, indifferent, and inclined to tolerate all religions in the State, provided only that they, in their turn, were indifferent at any rate toward itself, and that they did not come troubling the State, either by disobeying her rulers or by attacking her old deities, dead and buried beneath their own still standing altars.
