Exploring the significance of Judas Iscariot for Christian theology and the difficult issues surrounding Judas, Anthony Cane shows that focusing on the tension between providential and tragic interpretations of Judas in the New Testament and in subsequent writing about Judas, is the key to understanding his significance. Building on the work of Karl Barth and Donald MacKinnon, Cane's argument sheds light not simply on the way Judas is understood, but on the way Jesus and the whole economy of salvation are understood. This book also highlights implications for the way in which issues relating to anti-Semitism and evil and suffering are most effectively explored.
