The Roman Index of Forbidden Books

A compact yet thorough guide, this work opens the door to the Catholic Church’s historic system of literary censorship. Written for readers who cannot devote extensive time to scholarly research, it distills the essential principles behind the Index of Forbidden Books, tracing its origins from early papal decrees to the revisions issued under Pope Leo XIII and Pope Pius X.

The author walks listeners through the structure of the Index, explaining who decides which works are barred and why, and outlining the legal and moral duties imposed on the faithful. Brief case studies—such as the famous Galileo episode—illustrate how the Church’s examination process functioned in practice, while the opening sections lay out the foundational constitutions that governed all decisions. By the end of the first act, listeners will grasp the rationale behind the censorship, the categories of prohibited literature, and the broader spiritual intent behind the Church’s protective measures.
