The brick church, dedicated in 1840, is the oldest standing Methodist church in Calvert County. The Calvert Circuit began in 1781 with services in homes. By 1789 this circuit had the largest membership in the United States. Fielder B. Smith gave land for this church. Other congregation members gave clay, baked the bricks, and provided much of the interior woodwork. In 1882, the Smithville Circuit of three churches was formed. In 1980 Smithville became a separate church.
