“A History of the Inquisitions: The Cathars and the Waldensians”

After five centuries free of major heresy, the Roman Church found itself confronted by new religious forces. The Cathars were an import from the east. The Waldensians were a native lay reform movement, once praised by the Church, but now radicalized and at odds with the Church. One thing was certain: the Church had no idea how to deal with heresy.
