This project generates conversation between the great thinkers of the Russian Orthodox tradition with the most significant Protestant theologian of the last century, Karl Barth. The body of Russian theological scholarship guided by sobornost challenges Barth, helping us to draw out necessary criticism while leading us toward unexpected insight, and vice versa. Accordingly, this collection not only illuminates but also stimulates discussions for those engaged in the study of Karl Barth’s corpus, the Orthodox tradition, and in the ecumenical discourse between East and West.
