Der Pfaffenspiegel / Historische Denkmale des Fanatismus in der römisch-katholischen Kirche

The author offers a historical critique of the Roman Catholic Church, tracing the growth of papal and priestly authority, detailing the tools—dogma, relic-veneration, institutional coercion—and claiming that faith-based fanaticism hindered social freedom. After an introductory survey of ecclesiastical power and censorship, the work compiles case studies of movements and persecutions such as the flagellants, Albigenses, Waldensians, Anabaptists, the Inquisition, and assaults on Jews, using both secular and clerical sources to document abuses. The stated aim is to strip away myths of clerical infallibility and enable readers to reassess the origins and effects of religious authority.
