Claim: Open Bible Standard Churches can be traced to the Azusa Street Revival, which took place in Los Angeles on April 9, 1906, and the early 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. The Azusa Street Revival was a historic revival meeting that took place in Los Angeles, California. The start of the three-year revival began on April 9, 1906 and continued until roughly 1915. It was led by William J. Seymour, an African-American preacher.
