Christian Montanism was a religious movement that emerged in the late 2nd century, founded by a Christian prophet named Montanus. It emphasized the direct revelation of the Holy Spirit and the importance of spiritual gifts, such as prophecy and speaking in tongues. Montanists believed that the end of the world was imminent and that they were living in a new age of the Spirit. The movement attracted followers in regions like Phrygia and spread throughout the early Christian world. However, it faced opposition from mainstream Christianity, which viewed its teachings as heretical. Over time, Montanism declined but left a lasting impact on discussions about prophecy and spiritual authority within the church.
