Reinhold Niebuhr is a priest in Detroit in the early 1920s. The son of German immigrants, he organizes against the ’s ascendancy in the 1925 mayoral campaign. His attention to social issues earns him the attention of the Detroit’s progressive bloc. And his progressive politics dispose him to respect , despite the lawyer’s atheism. Following the Sweet trials, Mayor appoints Niebuhr to head a blue-ribbon commission on the state of Detroit’s race relations—and joins him as the commission’s secretary. This work pushes Niebuhr towards an increasingly radical form of social theology that later influences Dr. Martin Luther King, Jr.
