Pentecostal churches believe that the Old and New Testaments are the word of God; that God, the Son and the Holy Spirit are three persons with once essence; that God is the creator; and that salvation is possible because of Jesus' death on the cross. Pentecostal churches also emphasizes that members have personal experiences with God by being baptized by the Holy Spirit.
Pentecostal churches have a "foursquare gospel" belief. "Foursquare" refers to the religion's four fundamental beliefs, including that Jesus saves, Jesus baptizes believers with the Holy Spirit, Jesus heals and Jesus is returning to earth to receive the saved. Pentecostals believe that baptism by the Holy Spirit is different from conversion. Believers baptized by the Holy Spirit live spiritual and empowered lives and may speak in tongues or perform divine healings.
Pentecostalism is a form of evangelical Protestantism that first appeared in the early 20th century when radical revivalists expected the second coming of Christ. The church takes its name from the Greek word Pentecost, which is the Jewish Feast of Week. This event commemorates when Jesus' early followers received the Holy Spirit as described in the second book of Acts. Pentecostalism includes 700 denominations and several independent churches, and the religion does not have a governing authority.
