Politics After Christendom argues that Scripture leaves Christians well-equipped for living in a world such as this. Scripture gives no indication that Christians should strive to establish some version of Christendom. Instead, it prepares them to live in societies that are indifferent or hostile to Christianity, societies in which believers must live faithful lives as sojourners and exiles. Politics After Christendom explains what Scripture teaches about political community and about Christians’ responsibilities within their own communities.

As it pursues this task, Politics After Christendom makes use of several important theological ideas that Christian thinkers have developed over the centuries. These ideas include Augustine’s Two-Cities concept, the Reformation Two-Kingdoms category, natural law, and a theology of the biblical covenants. Politics After Christendom brings these ideas together in a distinctive way to present a model for Christian political engagement. In doing so, it interacts with many important thinkers, including older theologians (e.g., Augustine, Aquinas, and Calvin), recent secular political theorists (e.g., Rawls, Hayek, and Dworkin), contemporary political-theologians (e.g., Hauerwas, O’Donovan, and Wolterstorff), and contemporary Christian cultural commentators (e.g., MacIntyre, Hunter, and Dreher).
