There have many revivals of Christianity. One of the latest 20th revivals was Pentecostalism that has a vitality in its worship. Pentecostal Churches have loud and lively music, hand clapping, testimonials, speaking in tongues, and prayers in the Spirit. There is an emphasis on the Holy Spirit that has often been forgotten in mainline churches. The fastest growing Churches are precisely these charismatic Pentecostal churches.
Sunday worship on the Sabbath is the key Christian ritual, with special emphasis on the Easter and Christmas ceremonies. Sunday is the day of worship rather than Saturday because Sunday is the day of the Lord’s resurrection. Thus, every Sunday is a little Easter celebration. Worship centers on Bible readings and their interpretation with sermons and testimonials. Prayers, hymns, chants and the Lord’s Supper, or the Eucharistic meal, remain a mainstay of most Christian worship services. The various Christian symbolic actions or sacraments grow out of a Trinitarian baptism based on a belief in Jesus Christ.
