A problem of the period concerned the merchants, bankers and artisans of Europe's largest cities and towns who resented the fact that local bishops of the Church controlled all of their commercial and economic activities. Although capitalism as a form of economic organization had not yet infiltrated Europe, these producers and money-makers knew that more money and power was theirs if only their lives were less regulated by the Church. Again, I think what we are witnessing here is the development of a secular concept of work and acquisition. Yet another problem facing the Church was that in the 16th century there were numerous reformers who were openly criticizing the Church for its numerous offenses. Priests married and then took mistresses, holy offices were bought and sold for the highest price, incompetence among the clergy became the rule, the congregation of more and more people in towns and cities perhaps exposed the amorality and immorality of the clergy. In a word, the problem was corruption.
Meanwhile, peasants in England, Italy, France, Germany and elsewhere were also on the move. They began to revolt openly against both the clergy and the aristocracy. Their grievances were the most complicated of all -- their revolt was against political, economic, social and religious authority. And despite the Inquisition, the work of the Dominicans and Franciscans, and even a holy crusade, heretics and heresies continue to grow more numerous and more vocal.
