A heretical movement founded by the prophet Montanus that arose in the Christian Church in Phrygia, Asia Minor, in the 2nd century. The movement held similar views about the basic tenets of Christian doctrine to those of the wider Church, although believing in new revelations and estasies, unapproved by the wider Church; the Bishop of Rome ultimately condemned the movement as heretical and excommunicated its adherents. It was a prophetic movement that called for a reliance on the spontaneity of the Holy Spirit and a more conservative personal ethic. Parallels have been drawn between Montanism and modern-day movements such as Pentecostalism, the charismatic movement, and the New Apostolic Reformation.
