First Methodist Church of Pittsburg was organized in 1857 by the Rev. J. W. Harvey Hamill. Its charter members included Major and Mrs. W. H. Pitts and others in the Pitts family, for whom the town was named. The congregation first worshipped in a log structure, then shared a 2-story frame building with the Masonic Lodge. A larger frame sanctuary was erected in 1888-89, and it was later replaced by the brick prairie style church constructed in 1904-05 during the pastorate of the Rev. E. L. Shettles. An educational wing was added in 1953, and in 1957, the fellowship's centennial year, membership was 546.
