St. Augustine on the Devil and his Power of Divination

Evil has always fascinated. Tormenting questions, such as: Why does God allow evil to exist? and How does God Almighty allow demons to get the science of divination?, has found categorical responses in St. Augustine's works. The bishop of Hippo, who over the centuries become one of the most important theologians influencing the development of Western Christianity and philosophy, has defined the concept of evil in the world and its image associated with the demons. The Augustinian position is to be followed in the author's Christian doctrine rejecting the Manichaeism.
