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 "metaphysical speculation," Bonhoeffer displays similar inclinations that situate Truth, Goodness, and Beauty as transcendental aspects of divine being. His theology affirms the pervasive "rhetoric" 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.
