Organized in 1887, First Christian Church was first served by the Rev. A.J. Bush, Sr. (1846-1920), a Civil War veteran who was instrumental in establishing Christian churches in many areas of the state. Previous buildings on this site were replaced in 1958 by a new brick sanctuary, with volunteers from the congregation providing most of the labor. The church has been involved in local and foreign missionary activities for many years. Offering assistance to people in need, First Christian Church continues to be an important part of the Rockdale community.
