This updated, revised edition of the important 1988 work examines the complex relationship between American ideals and increasing religious diversity. Since publication of the first edition, American religion has become more pluralistic and the central dynamic of welcoming vs. rejecting religious diversity is even more prominent and nuanced. Explored here are two competing visions of the American Dream as it relates to religion: America as a pluralistic society shaped by its diversity, and America as an assimilative society in which people of all backgrounds become "American."
