Montanism, known by its adherents as the
New Prophecy, was an
early Christian movement of the late
2nd century, later referred to by the name of its founder, Montanus. 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.
