Book excerpt: "A Secular Faith does precisely this. Darryl Hart, the highly regarded historian of religion, contends that appeals to Christianity for social and political well-being fundamentally misconstrue the meaning of the Christian religion. His book weaves together historical narratives of key moments in American Protestantism's influence on the nation's politics, plus commentary on recent writing about religion and public life, and expositions of Christian teaching. The tapestry that emerges is a compelling faith-based argument for keeping Christianity out of politics."--BOOK JACKET.
