Daniel Silliman has some excellent posts on the origins of the Pentecostal movement. His latest is on Charles Parham and his potential homosexual encounter with a young man, read it here. Excerpt:
In 1907 in San Antonio, in the heat of July and Pentecostal revival, Charles Fox Parham was arrested. Parham, the father of Pentecostalism, the midwife of glossolalia, was arrested on charges of “the commission of an unnatural offense,” along with a 22-year-old co-defendant, J.J. Jourdan.
Details are sketchy.
