In this work, J. Budziszewski examines evangelical political thought over the past fifty years through four key figures - Carl F. H. Henry, Abraham Kuyper, Francis Schaeffer, and John Howard Yoder - to argue that, in addition to Scripture, the evangelical political movement should be informed by the tradition of natural law. David L. Weeks (Azusa Pacific University) responds on Henry, William Edgar (Westminster Seminary) responds to the Schaeffer section, John Bolt (Calvin Seminary) comments on Kuyper, and Ashley Woodiwiss (Wheaton College) offers remarks on the Yoder portion. Jean Bethke Elshtain (University of Chicago) provides the afterword, summarizing the dialogue and offering her own observations. In addition, the book includes an introduction by Michael Cromartie of the Ethics and Public Policy Center.
