What, exactly, is an angel? Do angels bring us messages from God? Protect us? Warn us of impending danger? Are they all-knowing? Equal to God? And what about Satan? How did he get to be so evil? Is he an "evil god"? Why should we watch out for him? Then there are the demons. What is demonic possession? How did Jesus cast out demons? What does it mean that Jesus "descended into hell"? Angels, devils, and demons have fascinated humans since the beginning of time. Christians, with their rich biblical tradition based on both the Old and the New Testaments, have their own interpretations on the identities and functions of these good and evil spirits--interpretations frequently at odds with the "feel good" images cherished by New Age proponents and the marketers of sentimental products. In her new book Scripture scholar Irene Nowell, OSB, thoughtfully and thoroughly answers your questions about these supernatural beings that seem to hover between the highest realms of heaven and the depths of hell. From the most ancient traditions of our Hebrew ancestors in the faith to the latest teachings in the Catechism of the Catholic Church, Dr. Nowell mines them all to bring you a rich treasury of information about angels and devils. +.
