Ulrik Nissen addresses the difficulty that contemporary theology faces in trying to find a way to maintain both all the shared goods we cherish as political beings, and the call for Christians to be a particular people in the world and bear witness to Christ. Nissen stresses that Dietrich Bonhoeffer's Christological ethics allows for a polemical unity between the reality of the world and the reality of God, reconciled in the reality of Christ.

Based on a series of case studies that provide a point of departure for a robust reshaping of Christian humanism and responsibility, Nissen reads Bonhoeffer's ethics in the light of both his Lutheran heritage and contemporary challenges, highlighting the importance of his thought for political theology. By demonstrating the significant influence of Lutheran and Chalcedonian Christology in contemporary ethics, Nissen provides a robust argument for a love of the common reality we share as human beings, and a call for Christians to bear witness to Christ in the public world.
