“In this superb book, Wild taps a vast range of primary sources to piece together an eye-opening account of how a dynamic religious movement of urban renewal sought to save the post–World War II American city and mainline church from socioeconomic and spiritual crises of their own making. Cutting from Harlem to Houston, from Detroit to Los Angeles—and across the heart of the twentieth century—Wild elegantly captures the lofty hopes, street-level determination, unavoidable frustrations, and unsolvable paradoxes that shaded second-wave social gospelers’ radical theology and attendant quest to engage and heal the secular urban world. This is a major addition to the history of liberal religion, and political action, in the modern era.”
