Founded in the home of early settler and community namesake Israel Washington Speegle, this historic congregation formally organized in 1850 as Pleasant Grove Baptist Church. It was renamed Speegleville Baptist Church after the members joined with Greenwood Baptist Church in 1883. Part-time pastors and dedicated lay members have led the congregation throughout its history, and Sunday School, a summer revival with baptisms in Speegleville Creek, music, worship, and community outreach have been among its ministries and programs. The congregation has relocated over the years to accommodate the building and enlargement of Lake Waco.
