St. John is considered the "Mother Church" of the Methodist movement in Augusta, having either begun or cooperated in the origins of most of the Methodist churches in the Augusta area.
The original meeting house, a wooden frame structure built in 1801, is the oldest church building in Augusta. It was moved in 1844 to Reynolds Street where it still serves as the parish hall of Springfield Baptist Church, the oldest African-American church in the United States. At St. John itself, the first meetings for the formation of Paine College were held in 1883.
The present St. John Sanctuary was built in 1844 and expanded in the 1890's.
