Other independent bodies joined at later dates, including the Pentecostal Church of Scotland (founded in 1909 by Rev. George Sharpe) and the Pentecostal Mission (founded in 1898 by J.O. McClurkan), both in 1915. At this point, the Church of the Nazarene now embraced seven previous denominations and significant parts of two other groups. In time, the Church of the Nazarene and the Wesleyan Church would emerge as the two major denominations to gather in the smaller bodies of the 19th century Wesleyan-holiness movement. In subsequent decades, there were new accessions and mergers. In the 1922, more than one thousand members and most of the workers led by Joseph G. Morrison, from the Laymen's Holiness Association (founded in 1917) located in the Dakotas, joined the Church of the Nazarene. In the 1950s, there were mergers with the Hephzibah Faith Missionary Association (founded in 1893 in Tabor, Iowa) in 1950; the International Holiness Mission (founded in London in 1907 by David Thomas) merged on October 29, 1952; the Calvary Holiness Church (founded in Britain 1934 by Maynard James and Jack Ford), united on June 11, 1955 (though there were clergy who dissented from this decision and continued as the Calvary Holiness Church);[41] and the Gospel Workers Church of Canada (founded in Ontario in 1918) became part of the Church of the Nazarene on September 7, 1958. On April 3, 1988, an indigenous Church of the Nazarene in Nigeria, established in the 1940s, merged with the denomination.[42] The 2009 General Assembly authorized a committee with "the responsibility to approach "like-minded churches in the Wesleyan-Holiness tradition in order to pursue closer relations, with a goal of exploring the possibility of a merger or a collaborative relationship.
