Book excerpt: More often than not it's a class in the social sciences that challenges the faith of students, not a class in biology. Does critical understanding of our religious traditions, institutions, and convictions undercut them? Or can a modern social scientific approach deepen faith's commitments, making us full participants in today's intellectual culture? In these conversations with eminent sociologists Robert Bellah and Christian Smith, leading scholars probe the religious potential of modern social science--and its theological limits.
