This church traces its history to the 1870s, when African Methodist Episcopal Church services were held for Mexia's African American population. The church reportedly was used as a schoolhouse during Reconstruction. The African Methodist Episcopal (A.M.E.) Church of Mexia was formally organized about 1903. Between 1908 and 1915 it was renamed St. John's A. M. E. for Johnnie Lynn, a church member who became a pastor. Other notable members included church trustee Dr. S. M. Pollock, a Limestone County native who began a dental practice in Mexia in 1921. He served two terms as Mexia City Commissioner. The congregation thrived throughout the twentieth century. In 1994 a fellowship hall was erected. St. John's members continue in the traditions of their founders and predecessors. (2000)
