The twentieth century has witnessed suffering and human cruelty on a scale never before imagined. Yet, paradoxically, the doctrine of original sin has undergone neglect in recent years. In this sophisticated treatment of the biblical evidence for original sin, Henri Blocher offers a robust study that interacts with the best scientific, literary, and theological thinking on the subject. Building his argument on a detailed analysis of the scriptural evidence for original sin, especially looking at key texts in Genesis and Romans, Blocher shows, with due consideration to current intellectual objections to the doctrine, that while the nature of original sin is certainly a mystery, only belief in it makes sense of evil and wrongdoing.
