Guilhabert de Castres

Guilhabert de Castres was a prominent Cathar theologian. Born in Castres, he became a Cathar Perfect and, between 1223 and 1226, Bishop of Toulouse in the Cathar Church. In the theological debates in the early 13th century between the Cathars and the Papal representatives, he presented the Cathar arguments, including at the Debate at Montreal in 1206 and at the last Debate at Pamiers where he encountered Saint Dominic in 1207, prior to the Albigensian Crusades.
