This is the first book to offer a comparative analysis of the impact of the post-war 'Baby Boom' generation on Christianity around the world. Taking a cross-cultural approach, the contributors examine ten advanced countries, including England, France, Germany, Australia, and the United States, and explore the ways baby boomers have helped reshape and redefine 'establishment religions' — that is, the dominant, primarily Christian institutions. Their conclusions are broad and far-reaching, shedding light on the fate of religion in other countries now modernizing and those countries moving through the modern to the postmodern. Sociologists, historians, and scholars of religion will profit from the insights put forth here on religion in a postmodern context.
