Montanism

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