After graduating from the College of New Jersey, Balch became principal of the Lower Marlborough Academy in
Calvert County, Maryland. Balch also served in the
American Revolutionary War. In 1779, Balch was ordained as minister by the
Presbyterian church. After that, he arrived in
Georgetown, where he preached at Georgetown Lutheran Church. In 1780, he began preaching out of a small house used as a school during the week near Bridge Street, which is present-day
M Street. Balch also became headmaster of the Columbian Academy in Georgetown, which is where
George Washington sent his nephews. A building was constructed for the church on Bridge Street at Washington Street, on present-day 30th Street, in 1782. The church expanded in 1793 and again in 1801, but the size was still insufficient. A new structure was built in 1821, and the church later relocated to P Street the 1870s. Many notable residents of Washington and Georgetown attended the church. Balch preached to a large crowd after the death of
George Washington on December 12, 1799. ==Personal life==
