Pentecostalism or Classical Pentecostalism is a renewal movement within Protestant Christianity that places special emphasis on a direct personal experience of God through the baptism with the Holy Spirit. The term Pentecostal is derived from Pentecost, the Greek name for the Jewish Feast of Weeks. For Christians, this event commemorates the descent of the Holy Spirit upon the followers of Jesus Christ, as described in the second chapter of the Book of Acts.
