The National Shrine in Washington, DC has been deeply loved, blithely ignored, and passionately criticized. It has been praised as a dazzling jewel and dismissed as a towering Byzantine beach ball. In this intriguing and inventive book, Thomas Tweed shows that the Shrine is also an illuminating site from which to tell the story of twentieth-century Catholicism. He organizes his narrative around six themes that characterize U.S. Catholicism, and he ties these themes to the Shrines material culture--to images, artifacts, or devotional spaces. Thus he begins with the Basilicas foundation stone, weaving it into a discussion of brick and mortar Catholicism, the drive to build institutions. To highlight the Churchs inclination to appeal to women, he looks at fund-raising for the Mary Memorial Altar, and he focuses on the Filipino oratory to Our Lady of Antipolo to illustrate the Churchs outreach to immigrants. Throughout, he employs painstaking detective work to shine a light on the many facets of American Catholicism reflected in the shrine.
