Spiritual writer, theologian, and philosopher Fr. Robert Spitzer, S.J., Ph.D., tackles the topic of recognizing and overcoming spiritual evil. His focus is the human heart. His goal: our spiritual and moral transformation, which leads to true peace and genuine happiness.The book is divided into two main parts: (1) the realities of God's goodness and of spiritual evil, and (2) recognizing and overcoming the diabolical tactics of deception, temptation, and sin. The author synthesizes the best advice given by Catholic spiritual masters throughout the ages and gives a practical guide to implementing it in our busy lives.Father Spitzer provides the biblical and theological background of Jesus' victory over evil. He also explores the reality of the devil, including extraordinary manifestations of diabolic activity such as possession. With insights from modern psychology, he shows how prayer can transform the subconscious psyche, making us better able to resist temptation, detach from the world, and grow in holiness.
