Montanist (n.)

mid-15c., member of a millenarian and severely ascetic sect that believed in continual direct inspiration of the spirit and featured women in prominent roles, from Montanus, Christian-inspired prophet in the wilds of Phrygia after c. 160 C.E. The heresy persisted into the 6c. and helped bring prophecy into disrepute in the established Church. Related: Montanism.
