This bookcritically examines Bonhoeffer’s social theology in Sanctorum Communio from the perspective of Žižek’s theological materialism. Specifically, it refers to Žižek’s struggling universality of abandonment and its ethic of indifference in consideration of Bonhoeffer’s transcendental personalist community of saints and its ethic of universal love. As such, it represents an attempt to reflect on the content, act, and implication of theological thought without presuppositions and an argument for the necessity of such an approach—a radical approach that is true to theology’s critical character of challenging narratives and revealing exceptions in search of truth.
