This style is increasingly endangered. It was once the common style of most African-American congregations in the rural South.
Many of the details of St. James A. M. E. Zion Church’s history are lost to time, but the congregation’s beginnings were in the 1890s. Sam Mitchell, who was married to Sudie Rountree Mitchell, was one of its founders, and Will Mincey was its earliest pastor. The church structure itself was built in 1908 under the leadership of Reverend J. H. Williams. The building was erected by Reverend R. Lee with the help of a group of trustees. –from The Swainsboro Forest-Blade, 3 December 2014.
