“In 2011, there were an estimated 584 million Pentecostal and Charismatic Christians worldwide. They made up 8.5 percent of the world’s population and 27 percent of all Christians. There were 279 million Pentecostals and over 300 million Charismatics. Pentecostal and Charismatic Christianity is second in size only to the Roman Catholic Church.” (Source: David Barrett, “Christian World Communions: Five Overviews of Global Christianity, AD 1800-2025,” International Bulletin of Missionary Research, Volume 33, No. 1, January 2009, 31.)
Pentecostals are Christians who believe that the gifts of the Spirit described in the New Testament like the gift of tongues, healing, and casting out demons, are available and expected to be experienced by God’s people today. Our worship is characterized by lively responses to a palpable sense of God’s presence. We are so named after what happened to the disciples on the Day of Pentecost (read Acts 2) and our insistence that the essence of such experiences are to be normative for today.
Charismatics are believers who originally worship in mainline churches such as Methodists, Anglicans, Lutherans, and Presbyterians. They had Pentecostal experiences and hold almost similar beliefs and practices as Pentecostals, but continue to attend and serve in their traditional churches.
Admittedly, there is considerable overlap in usage of both terms and such strict definitions have become porous and interchangeable in the recent decade or two. Who cares anyway? Probably the theologian and the researcher.
Reminder: 8 June is Pentecost Sunday.
