The first church in this area, then known as Pine Springs, was established as an ecumenical church in 1853. The Rev. E. M. Carter and Elias Stephens, a deacon, established the Union Baptist Church in 1866 with 15 members, all formerly of the earlier congregation. The church was renamed Pine Springs Baptist Church in 1881. Members erected a white frame building on this site in 1887. The community was renamed Mixon when a post office was established in 1889. The Rev. W. R. White, later president of Baylor University, served the church from 1911 to 1913. The settlement grew over the next several years. In 1946 the church was renamed First Baptist Church of Mixon. A new building was erected in 1952. Among the last vestiges of Mixon, the church continues in the traditions of its founders. (2000)
