Although probably many of the members of the “Sam Fife – Body of Christ- Move of God” do not know it, their doctrine and methods largely came from the Latter Rain, a movement started in North Battleford Saskatchewan in 1948. They started as a prophetic movement, had five fold ministries, used typological preaching, and had conventions on the holidays. George Hawtin and George Warnock where among the leaders. They still exist. I relate just a bit about the history of the founding here.
