in the middle ages, who would have been considered a heretic by the church?

During the Middle Ages, anyone who was perceived to be deviating from the established teachings of the Catholic Church was considered a heretic. This included individuals who held different religious beliefs, questioned the authority of the pope or church hierarchy, or practiced alternative forms of worship. Some notable examples of heretics during this time include the Cathars, Waldensians, and Hussites. The church often dealt with heretics harshly, and many were subject to torture, imprisonment, or execution.
