Arnoldist
From Infogalactic: the planetary knowledge core
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.
