Arnoldists

Arnoldists were a Christian sect in the 12th century, named after Arnold of Brescia who criticized the great wealth and possessions of the Roman Catholic Church, and preached against baptism and the Eucharist. His disciples were also called "Publicans" or "Poplecans", a name probably deriving from Paulicians. The Arnoldists were condemned as heretics by Pope Lucius III in the Ad abolendam during the Synod of Verona in 1184.

Their tenets would later be addressed by Bonacursus of Milan, c.1190, in his Manifestatio haeresis Catharorum, which refuted Arnoldist evangelical poverty and the incapacity of sinful priests to administer the sacraments.
