When the Roman Empire gradually became an anarchy of hostile fragments, every large monastery, every small town, girded itself with walls and tended to become the germ of a new civilisation. Popes, kings, and great lords, haunted by reminiscence of the vanished empire, made spasmodic attempts to subject such centres to their rule and tax them for their maintenance. In the first times, the Church--the See of Rome--made by far the most successful attempt to get its supremacy acknowledged, and had therefore fewer occasions to resort to violence. It was more respected and more respectable than the other powers which claimed to rule and tax these immured and isolated communities dotted over Europe; but as time went on, the Church became less and less beneficent, more and more tyrannical. Meanwhile kings and emperors, having learned wisdom by experience, found themselves in a position to take advantage of the growing bad odour of the Church; and by favouring the civil communities and creating a stable hierarchy among the class of lords and barons from which they had emerged, were at last able to face the Church, with its _protégés,_ the religious communities, on an equal footing. The religious communities, owing to the vow of celibacy, had become more and more stagnant, while the civil communities increased in power to adapt themselves to the age. All that was virile and creative combined in the towns; all that was inadequate, sterile, useless, coagulated in the monasteries, which thus became cesspools, and ultimately took on the character of festering sores by which the civil bodies which had at first been purged into them were endangered. Luther tells us how there was a Bishop of Würzburg who used to say when he saw a rogue, "'To the cloister with you. Thou art useless to God or man.' He meant that in the cloister were only hogs and gluttons, who did nothing but eat and drink and sleep, and were of no more profit than as many rats." And the loathing that another of these sties created in the young Erasmus, and the difficulty he had to escape from the clutches of its inmates--never feeling safe till the Pope had intervened--show us that by their wealth and by the engine of their malice, the confessional (which they had usurped from the regular clergy), they were as formidable as they were useless. It became necessary that this antiquated system of social drainage should be superseded.
