How was this inveterate custom to be broken through? How the open, honest marriage to be perverted into clandestine union? For to abolish it wholly was beyond the power of the Popes and Councils. It was in vain to appeal to the bishops, they sympathised with their clergy. It was in vain to invoke the secular arm; the emperors, the podestas, supported the parish-priests in their contumacious adherence to immemorial privilege. 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.
