This book is a survey and analysis of the European Reformation of the sixteenth century. During this period western Christianity underwent the most dramatic changes in its entire history. From Iceland to Transylvania, from the Baltic to the Pyrenees, the Reformation divided churches and communities into 'Catholic' and 'Protestant', and created varying regional and national traditions. The new Protestant creed rejected traditional measures of piety--vows, penances, pardons, and masses--in favor of sermons and catechisms, and an everyday morality of diligence, neighborly charity, and prayer. In the process, it involved many of Europe's people for the first time in a political movement inspired by an ideology and nourished by mass communication. Using the most recent research, Cameron provides a thematic and narrative synthesis of the events and ideas of the Reformation. He examines its social and religious background, its teachers and their message, and explores its impact on contemporary society.
