Of course there was a violent opposition. A great outcry was raised, especially in Germany. The whole body of the secular priests exclaimed against the proceeding. At Mentz they threatened the life of the archbishop, who attempted to enforce the decree. At Paris a numerous synod was assembled, in which it was voted that Gregory ought not here to be obeyed. But Gregory was stronger than his rebellious clergy,--stronger than the instincts of human nature, stronger than the united voice of reason and Scripture. He fell back on the majestic power of prevailing ideas, on the ascetic element of the early Church, on the traditions of monastic life. He was supported by more than a hundred thousand monks, by the superstitions of primitive ages, by the example of saints and martyrs, by his own elevated rank, by the allegiance due to him as head of the Church. Excommunications were hurled, like thunderbolts, into remotest hamlets, and the murmurs of indignant Christendom were silenced by the awful denunciations of God's supposed vicegerent. The clergy succumbed before such a terrible spiritual force, The fear of hell--the great idea by which the priests themselves controlled their flocks--was more potent than any temporal good. What priest in that age would dare resist his spiritual monarch on almost any point, and especially when disobedience was supposed to entail the burnings of a physical hell forever and ever? So celibacy was re-established as a law of the Christian Church at the bidding of that far-seeing genius who had devised the means of spiritual despotism. That law--so gloomy, so unnatural, so fraught with evil--has never been repealed; it still rules the Catholic priesthood of Europe and America. Nor will it be repealed so long as the ideas of the Middle Ages have more force than enlightened reason. It is an abominable law, but who can doubt its efficacy in cementing the power of the popes?
