As early as 1835, Baptists were worshipping in this area. In 1868, when Calvert was founded, Houston & Texas Central Railroad donated lots for a church. Until a brick edifice was built in 1873 on that land (at Hanna and Pine), services were held in a private residence. This church was host (1875) to Baptist State Convention; (1875, 1878) the State Sunday School Convention; (1912) Hood's Texas Brigade Reunion. Sent (1907) Alyne Guynes Muirhead and (1915) Sammie Guynes Johnson as missionaries to Brazil. Since 1947, sponsors Mexican mission. Elmo Baptist Church merged with Calvert, 1969.
