The history of the sect was as follows:--Manes, a Persian heathen, flourished in the middle of the third century, dying about 277, the founder of a new religion, after having been, like Simon Magus, a temporary and nominal convert to the Gospel. He was not an inventor of his religion, but merely a blender of the earlier Gnostic heresies with the Persian doctrines of Zoroaster, added to a somewhat larger element of Christianity than the Gnostics had chosen to accept. The Paulicians were a sect which took shape about 660, out of Manichaeism, or the religion of Manes. They were cruelly persecuted by the Byzantine Emperors, during two whole centuries, and spread to the West by degrees; one stream emigrated to Bohemia, where it became the parent of Hussitism; the other to the south of France, where it was called Albigensianism. The fundamental dogma of this new Manichaeism was a dualism of good and evil principles or gods, equally matched. The evil was the origin of the visible creation, the world and men's bodies; the good God was the creator of the invisible world and men's souls. The opposition of matter and spirit constituted the basis of their moral systems. These systems were diverse; some, regarding everything natural as evil, abstained from meat, from marriage, and from all employments; whilst others, regarding the soul as so distinct from the body as to be incapable of being soiled by any of its actions, gave themselves up to the grossest licentiousness. The moral condition of Provence, where Albigensianism held sway, was like Sodom and Gomorrah, as may be seen by the poetry of the troubadours; so that God's wrath could not but fall on a land so polluted. The licentiousness which this creed encouraged, helped to make it spread, and the Christianity of the whole of the south of France was imperilled. At the head of these heretics, the Count of Toulouse invaded the lands of the King of Aragon, devastated them, robbed the churches, burnt the monasteries, and ill-treated the clergy, "and slaughtered the Christians of either sex, and every age, without mercy," says Matthew Paris. "But this being at length made known, their heretical aggression was put down by the faithful Christians, who, at the command of Pope Gregory, had come as crusaders from various parts of the West, for the defence of the Christian faith."
