Local Pentecostal Churches are found throughout North America, and in most countries of the world. They share a common foundation of faith, and all trace their origins to the biblical Book of Acts, and to certain events from more recent history. Beyond these commonalities, local Pentecostal Churches vary widely in their specific theological beliefs, in their governmental structure, in the style of worship they embrace, and in the size of local congregations. Most local Pentecostal Churches consider themselves Protestant, while some prefer more specific terms such as Evangelical, Full Gospel, Charismatic, Four Square, or Apostolic. They all share the view that God makes spiritual power available to believers through the Holy Spirit. This power is believed to take different forms in local Pentecostal Churches, and there is a variety of spiritual manifestations associated with this power. Local Pentecostal Churches are not all part of the same denomination. Major denominations within Pentecostalism include the Assemblies of God, the Church of God, and the Church of God in Christ, the United Pentecostal Church International, and various Wesleyan-Holiness churches. A recent study found more than 10,000 different Pentecostal denominations in the world. The reason for so many is the lack of centralized control over local Pentecostal Churches. Their views on Scripture are generally consistent. All believe in the truth and sufficiency of the Bible, and the important ministry of the Holy Spirit. Subtle differences will be found in the application of these beliefs in the local Pentecostal Churches. It is important to investigate various local Pentecostal Churches before making a decision to become a part of one. Speaking to the pastors or church leaders will provide a greater understanding of each churchs perspectives and practices.
