Claim: Open Bible Standard Churches can be traced to the Azusa Street Revival and the stark opposition to the teachings of Martin Luther.
Evidence: The OBSC's origins are found in two smaller Pentecostal groups which can be traced to the Azusa Street Revival: the Bible Standard Conference founded in Eugene, Oregon in 1919 and the Open Bible Evangelistic Association founded in Des Moines, Iowa, in 1932; as both were similar in doctrine and structure, the two groups amalgamated in 1935.
