Pentecostalism or classical pentecostalism is a Christian charismatic movement of Protestantism that emphasizes direct personal experience of God through baptism with the Holy Spirit.The term Pentecostal is derived from Pentecost, an event that commemorates the descent of the Holy Spirit upon the Apostles and other followers of Jesus Christ while they were in Jerusalem, as described in the Acts of the Apostles (Acts 2:1–31).

Like other forms of evangelical Protestantism, Pentecostalism adheres to the inerrancy of the Bible and the necessity of the New Birth: an individual [[repentance]] of their sin and "accepting Jesus Christ as personal Lord and Savior". It is distinguished by belief in the "baptism in the Holy Spirit" that enables a Christian to "live a Spirit-filled and empowered life". This empowerment includes the use of [[spiritual gifts]]: such as [[speaking in tongues]] and [[spiritual healings]]. Because of their commitment to biblical authority, spiritual gifts, and the miraculous, Pentecostals see their movement as reflecting the same kind of spiritual power and teachings that were found in the Apostolic Age of the Early Church. For this reason, some Pentecostals also use the term "Apostolic" or "Full Gospel" to describe their movement. (Wikipedia)
