Montanus was a faithful priest turned heretic. He claimed to be filled with Holy Ghost, so much so, that his teachings excelled even that of Tradition and the Apostles. He leaned heavily on emotionalism. He preached revival and renewal, but many of his practices were from the devil. His heresy was condemned in the 2nd Century. Yet his error has returned in greater force today. Let us not confuse the Holy Ghost with the spirit of the world, of revolution, or of the devil. Forget not the Holy Ghost, pray for His gifts, and hold fast to Tradition.
