To carry through the reform on which they were bent, to utterly abolish the marriage of the clergy, the appeal must be made to the people.

In Milan this was practicable, for the laity, at least the lower rabble, were deeply tinged with Patarinism, and bore a grudge against the clergy, who had been foremost in bringing the luckless heretics to the rack and the flames; and one of the most cherished doctrines of the Patarines was the unlawfulness of marriage. What if this anti-connubial prejudice could be enlisted by the strict reformers of the Church, and turned to expend its fury on the clergy who refused to listen to the expostulations of the Holy Father?

The Patarines, whom the Popes were about to enlist in their cause against the Ambrosian clergy, already swarmed in Italy. Of their origin and tenets we must say a word.

It is a curious fact that, instead of Paganism affecting Christianity in the earliest ages of the Church, it was Christianity which affected Paganism, and that not the Greek and Roman idolatry, which was rotten through and through, but the far subtler and more mystical heathenism of Syria, Egypt, Persia, and Mesopotamia. The numerous Gnostic sects, so called from their claim to be the possessors of the true gnosis, or knowledge of wisdom, were not, save in the rarest cases, of Christian origin. They were Pagan philosophical schools which had adopted and incorporated various Christian ideas. They worked up Biblical names and notions into the strange new creeds they devised, and, according as they blended more or less of Christian teaching with their own, they drew to themselves disciples of various tempers. Manes, who flourished in the middle of the third century, a temporary and nominal convert to the Gospel, blended some of these elder Gnostic systems with the Persian doctrines of Zoroaster, added to a somewhat larger element of Christianity than his predecessors had chosen to adopt. His doctrines spread and gained an extensive and lasting hold on the minds of men, suppressed repeatedly, but never disappearing wholly, adopting fresh names, emerging in new countries, exhibiting an irrepressible vitality, which confounded the Popes and Churchmen from the third to the tenth centuries.

The tradition of Western Manicheism breaks off about the sixth century; but in the East, under the name of Paulicians, the adherents of Manichean doctrines endured savage persecutions during two whole centuries, and spread, as they fled from the sword and stake in the East, over Europe, entering it in two streams—one by Bulgaria, Servia, and Croatia, to break out in the wild fanaticism of the Taborites under Zisca of the Flail; the other, by way of the sea, inundating northern Italy and Provence. In Piedmont it obtained the name of Patarinism; in Provence, of Albigensianism.

With Oriental Manicheism, the Patarines and Albigenses of the West held that there were two co-equal conflicting principles of good and evil; that matter was eternal, and waged everlasting war against spirit. Their moral life was strict and severe. They fasted, dressed in coarse clothing, and hardly, reluctantly suffered marriage to the weaker, inferior disciples. It was absolutely forbidden to those who were, or esteemed themselves to be, perfect.

Already, in Milan, St Heribert, the married archbishop, had kindled fires, and cast these denouncers of wedlock into them. In 1031 the heretics held the castle of Montforte, in the diocese of Asti. They were questioned: they declared themselves ready to witness to their faith by their blood. They esteemed virginity, and lived in chastity with their wives, never touched meat, and prayed incessantly. They had their goods in common. Their castle stood a siege. It was at length captured by the Archbishop. In the market-place were raised a cross on one side, a blazing pyre on the other. The Patarines were brought forth, commanded to cast themselves before the cross, confess themselves to be heretics, or plunge into the flames. A few knelt to the cross; the greater number covered their faces, rushed into the fire, and were consumed.[13]

St. Augustine, in his book on Heresies, had already described these heretics. He, who had been involved in the fascinating wiles of Manicheism, could not be ignorant of them. He calls them Paternians, or Venustians, and says that they regarded the flesh as the work of the devil—that is, of the evil principle, because made of matter.

In the eleventh century, in Lombardy, they are called Patarines, Patrins, or Cathari. Muratori says that they derived their name from the part of the town of Milan in which they swarmed, near the Contrada di Patari; but it is more probable that the quarter was called after them.
