Open Bible Standard Churches can be traced to the Azusa Street Revival and the stark opposition to the teachings of Martin Luther.
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.
