A celebratory launch of Karen Kilby's book published by T&T Clark in 2020. Karen is in conversation with Linn Tonstad, Katherine Sonderegger, and Simon Oliver. They discuss the volume which brings together reflections on Trinitarian theology, on evil, sin and suffering, and even on mathematics, in order to probe two key questions: What are the limits of thought about God and the world? And what is the place of mystery in theology?
