Book excerpt: This book probes the relationship between Martin Heidegger and theology in light of the discovery of his Black Notebooks, which reveal that his privately held Antisemitism and anti-Christian sentiments were profoundly intertwined with his philosophical ideas. Heidegger himself was deeply influenced by both Catholic and Protestant theology. This prompts the question as to what extent Christian anti-Jewish motifs shaped Heidegger’s own thinking in the first place. A second question concerns modern theology’s intellectual indebtedness to Heidegger. In this volume, an array of renowned Heidegger scholars – both philosophers and theologians –investigate Heidegger’s animosity toward the biblical legacy in both its Jewish and Christian interpretations, and what it means for the future task and identity of theology.
