Paulicianism is a term used to describe a Christian sect that originated in the 7th century in Armenia. The followers of Paulicianism believed in the dualistic concepts of good and evil, and rejected the teachings of the Orthodox Church. Alternative synonyms for Paulicianism include the terms "Paulicinianism," "Paulicians," and "Paulician heresy." These terms all refer to the same religious movement and have been used interchangeably by scholars. Other terms that have been used to describe dissenting Christian groups in the same region and time period include "Bogomilism" and "Catharism." These terms are not directly related to Paulicianism but reflect similar religious movements that also rejected the authority of the Orthodox Church.
