In the early 1900s, the Pentecostal revival touched a small local church known as the “Baltimore Branch of the Christian and Missionary Alliance.” Pastor Edward Staudt developed an interest in the Pentecostal movement and soon realized what he had been missing. After receiving the Baptism in the Holy Spirit, he began teaching his congregation about this Biblical experience. On June 4, 1923, they formed a new church called the “Full Gospel Church of Baltimore” and met on North Fulton Avenue in West Baltimore. In time, the growing congregation built a new brick church in Baltimore on the corner of Saratoga and Monroe.

Alexander Clattenburg was called to pastor the church in 1942. In 1945, the name was changed to Trinity Assembly of God. The church was soon experiencing such growth that construction was begun on a new building at Hartford Road and Parkside Drive. As a visionary, Rev. Clattenburg believed God was leading the congregation to relocate to the present property along the beltway. Rev. Clattenburg frequently came out to the property, prayed over it, and asked God to set it apart for our church. Two years following his death in 1972, the land was finally purchased where the church now stands.
