“The roots of American pentecostalism reach deep into the history of ecstatic Christianity. Pentecostal leaders trace their origins through George Fox and the Quakers, John Wesley and early Methodism, the Plymouth Brethren, William Booth and the Salvation Army, and other similar men and movements. More recently, American pentecostalism grew out of a deepening of spiritual life associated with the holiness movement at the end of the nineteenth century. Participants in this nebulous movement, both in America and abroad, looked beyond the conversion experience to continual personal encounters with God for the Christian” (David Edwin Harrell, Jr., All Things Are Possible: The Healings and Charismatic Revivals in Modern America, 11).
