Book excerpt: Building on recent engagements with Barth in the area of theologies of religion, Karl Barth and Comparative Theology inaugurates a new conversation between Barth’s theology and comparative theology. Each essay brings Barth into conversation with theological claims from other religious traditions for the purpose of modeling deep learning across religious borders from a Barthian perspective. For each tradition, two Barth-influenced theologians offer focused engagements of Barth with the tradition’s respective themes and figures, and a response from a theologian from that tradition then follows. With these surprising and stirringly creative exchanges, Karl Barth and Comparative Theology promises to open up new trajectories for comparative theology. Contributors: Chris Boesel, Francis X.
