To the beat of their drums, missionaries from the "Save-a-Soul Mission"—a dead ringer for the Salvation Army—march onstage in Guys and Dolls, the 1950 Broadway musical comedy. By opening her study of the Salvation Army with this image, Diane Winston, a journalist turned academic historian, foreshadows several of her book's major insights. As her subtitle indicates, Salvationism was an urban phenomenon. She traces its history in New York City between 1880 and 1950 to show that, though the majority of the Army's recruits came from small town and rural areas, the Army's Holiness religion was born and grew up in cities. Furthermore, the Army used the format of secular, popular entertainment to present its religious message.
