This work provides the first book-length study on Heidegger's relation to the philosophy of religion, offering greater accessibility into an area that continues to fascinate philosophers, theologians, and all those interested in the philosophy of religion. The book deals intimately with hotly debated topics such as Heidegger's interpretation of Saint Paul, Nietzsche and the death of God, ontotheology, and Heidegger's discussion of the 'last god', taking into account the early, middle, and later texts of Heidegger. Significantly, Vedder draws heavily on Heidegger's "The Phenomenology of Religious Life", long available in German, but only recently available to English readers. Vedder describes the tension between religion and philosophy, on the one hand, and religion and poetic expression, on the other. If we grasp religion completely from a philosophical point of view, we tend to neutralise it; but if we conceive it in a simply poetic way, we tend to be philosophically indifferent to it. Vedder demonstrates how Heidegger speaks a 'poetry of religion', a description of humanity's relationship to the divine, and why Heidegger's thinking is ultimately a theological thinking.
