An introductory textbook to Christian social ethics in the contemporary urban American context, this text applies a reformed theory of justice and power to contemporary urban social-ethical problems. The topics include: the urban ethos, urban theology, power in the urban setting, love and justice, evangelism and social action, John Calvin's economic theory, contemporary business ethics, racism, political ethics and housing, and a concluding chapter on peacemaking and the technological city. Rejecting the pessimism of French Protestant Jacques Ellul and the optimism of Boston theologian Harvey Cox, it maps out the terrain of a Christian realist urban ethic.
