In response to actual questions many people have asked about angels and demons, well-known author and philosophy professor Peter Kreeft separates fact from fantasy and myth from reality as he answers 101 common questions about these spiritual beings. Based on a very popular college course he teaches on this subject, this book responds to the incredible amount of interest in angelic beings and attempts to clear up some of the misinformation abounding in numerous books today on what we really know about these mysterious spirits.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.
