Dietrich Bonhoeffer is a celebrated and enigmatic figure in theology. Though he is known for advocating a concrete and worldly Christianity, Justin Mandela Roberts argues that his theology is in continuity with a participatory ontology, especially as seen in the ressourcement movement and Radical Orthodoxy. While critical of such "e;metaphysical speculation,"e; Bonhoeffer displays similar inclinations that situate Truth, Goodness, and Beauty as transcendental aspects of divine being. His theology affirms the pervasive "e;rhetoric"e; of doxology, details the economy of reciprocal gift-giving, and celebrates the sacramentality of creation. Sacred Rhetoric contributes to the ongoing discussion of metaphysics, and also serves as a supplement to the debate between Karl Barth and Erich Przywara.
