"It started in the American heartland, in the twilight of the nineteenth century. First hundreds, then thousands, then tens of thousands of Baptists and Methodists, along with a smaller number of Quakers, Mennonites, and Presbyterians, left their natal fellowships to join one of the great religious migrations of modern times. Some pulled out and some were kicked out, but most just drifted away. However separated, all sought new communions more visibly filled with the New Testament church's supernatural power. These spiritual adventurers went by a variety of names -- including premillennialists, holiness folk and, from the lips of outsiders, holy rollers.
"[...] In the fire-baptized services of the late 1890s, one leader remembered, 'people screamed until you could hear them for three miles on a clear night, and until the blood vessels stood out like whip cords.'"-- Grant Wacker, Heaven Below: Early Pentecostals and American Culture.
