pentecostal Christianity
A type of fundamentalism that stresses faith healing and baptism by the Holy Spirit. The spirit manifests itself when followers speak in unknown tongues. Pentecost was an ancient Hebrew festival, and, according to the Book of Acts, on the first Pentecost after the crucifixion of Jesus of Nazareth, the apostles spoke in tongues when they heard a sound like the rush of a mighty wind.
