Drawing on the Bible, traditional Church teaching and St. Thomas Aquinas, Kreeft gives straight, clear answers to the perennial and philosophical questions asked about angels and demons throughout time. In his typical lucid, profound and sometimes humorous style, Kreeft answers such questions as "What are angels made of?", "How do angels communicate with God?", "How do angels communicate with us?", "Do demons, or devils, or evil spirits really exist?" and many more. Includes angel art.
