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 ecstasies, 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.
It originated in Phrygia, a province of Asia Minor, and flourished throughout the region, leading to the movement being referred to elsewhere as "Cataphrygian" (meaning it was "from Phrygia") or simply as "Phrygian". It spread rapidly to other regions in the Roman Empire at a time before Christianity was generally tolerated or legal. It persisted in some isolated places into the 6th century.
Usage examples of "montanism".
It is generally agreed that Tertullian became a Montanist about the year 200: his work, de Corona Militis, appears to have been written, at the earliest about the year 202 before the persecution of Severus: it may be maintained, then, that it is subsequent to the Montanism of the author.
