The Church of the Heavenly Rest on New York City's Upper East Side is the masterwork of Hardie Phillip of Mayers, Murray & Phillip, the successor firm of Bertram G. Goodhue Associates. Completed in 1929 in a pioneering neo-Gothic style, it employed traditional forms and massing in a modern way, marrying modern skyscraper technologies with a Gothic aesthetic. Inside, it showcased the talents of master sculptors, Lee Lawrie, Ulric H. Ellerhusen, and Malvina Hoffman, resulting in an eye-filling array of site-specific Deco- and Moderne-inspired artworks, furnishings, and decoration that melded traditional Christian iconography with Jazz Age exuberance. Commissioned by church leadership in 2020, GDPC's work on the National Register Nomination entailed an exhaustive review of drawings and correspondence by its architect and others at Columbia University's Avery Drawings and Archives, as well as numerous books and journals detailing its architect, engineer, artists and artisans. Listed as the Church of the Heavenly Rest and the Chapel of the Beloved Disciple, the building now occupies its rightful place among the pioneering works of ecclesiastical design from the 1920s.
