The Worldwide Church of God (WCG), founded in 1933, is a North American Adventist church that strongly emphasizes biblical prophecy. Although it deviated from Protestant orthodoxy in a number of ways, a major doctrinal and organizational transformation occurred in the late 1980s and early 1990s that converted it into an evangelical denomination. Subsequently, a number of schisms resulted in an exodus of half its adherents. The most recent (2004) estimated membership is 63,000 worldwide.
