This book examines the ways that religious beliefs affect the development of law and public policy in the US. Koch and Gates (both, Appalachian State Univ.) adopt the position that US public policy is developed through conflict between an in-group and an out-group. When the in-group is Christian, the public policies produced will have a strong Christian component. In chapter 1, the authors present their argument that there is a persistent element in US culture that can be considered medieval. Medieval culture is pre-modern and its ideology is based in religious truths and universality. The remainder of the book examines the history of public policies that are created by the influence of religion in the political sphere. Chapter 2 describes the contours of the debate over teaching evolution in public schools. Chapter 3 examines the development of the US flag as a quasi-religious icon. Religious influences on crime and punishment are the focus of chapter 4. Chapter 5 considers the impact of religious views on the functions of the human body. The final chapter emphasizes the authors' argument that their work is not anti-spiritual, but anti-dogmatic. US public policy should be grounded in modern concepts, not ancient writings. Summing Up: Recommended.
