The central Middle Ages in western Europe witnessed both a significant growth in the cult of the Virgin Mary and the rise of the dualist heretical movements known as the Cathars. Whilst the Cathars' dualism meant they denied any role for the Virgin Mary in the incarnation, nevertheless they often assigned her an important place in their beliefs. This article explores the considerable affinities which existed between contemporary orthodox doctrines and heretical teachings on Mary and, through a case study of the Disputatio inter catholicum et paterinum hereticum, examines the close relationship between anti-Cathar polemic, orthodox biblical exegesis and heretical belief.
