Broadway Tabernacle moved to 56th and Broadway and the construction of a ten-story parish house. The church hosted over 1,200 meetings in 1910, supported soldiers in WWI, and aided actors during the Great Depression. The pastors helped establish the New York Peace Society, defended the Scottsboro Boys, supported the NAACP, and led pacifist efforts. Despite opposing war, the church welcomed servicemen during WWII.
Broadway UCC continued its human rights advocacy into the 1960s, supporting the March on Washington and affordable housing efforts. Facing costly repairs, the church sold its property in 1969, moving multiple times before settling at St. Paul and St. Andrew. In 1991, it became an Open and Affirming congregation, supporting LGBTQ+ rights, anti-apartheid efforts, and social justice ministries.
