Pentecostalism or classical Pentecostalism is a movement within the evangelical wing of Protestant Christianity 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 celebrating the Feast of Weeks, 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 being born again: an individual repenting of their sin and "accepting Jesus Christ as their personal Lord and Savior". It is distinguished by belief in both the "baptism in the Holy Spirit" and baptism by water, 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 divine healing. 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.
