Using both an insightful and playful approach, Edwards analyzes the teachings of the Swiss Protestant theologian Karl Barth. Looking particularly at Barth's Church Dogmatics — a four volume work that explores principles of the Christian gospel — Edwards blends these religious topics with music of our generation. In addition to through-provoking discussions on Barth’s work, Christ is Time (Cascade Books)  offers a playlist of great hits from a variety of bands including Smashing Pumpkins, Pearl Jam, and Metallica, on trinity, Christology, prayer, and more.
