I came across this website by a group of Pentecostals and Charismatics that promotes peace and justice. Many early Pentecostals supported peace and nonviolence. This group is seeking to restore this early Pentecostal heritage. (http://pcpj.org/)
The group was founded in July 2001 as the Pentecostal Charismatic Peace Fellowship and changed its name to Pentecostals and Charismatics for Justice and Peace in 2007. (http://en.wikipedia.org/wiki/Pentecostal_Charismatic_Peace_Fellowship). Let us hope that this movement gains ground among both Pentecostal and Charismatic churches.
