What theological claim made Catharism a more radical challenge to the Church than the Waldensian movement?
Think about your answer, then reveal below.
Model answer: Cathars held a dualist cosmology in which the material world was evil and created by a lesser evil god, making all material sacraments (baptism, Eucharist) meaningless. This rejected the entire sacramental system, not just clerical authority. Waldensians accepted orthodox theology but challenged institutional authority by insisting on lay Bible reading and preaching.
The distinction matters because Waldensians were, in a sense, more recoverable — they wanted to reform the Church from within its own tradition. Cathars required a completely different metaphysical system to be right, which is why the Church responded to them not just with inquisition but with military crusade.
