There is something of a mystery about the words 'angel' and 'demon'. They are not really English words at all, but Greek words simply written with letters from our alphabet. This is because when the original Greek words were being translated, no one really knew what they meant. This book looks at the range of their uses in the Bible and other classical Greek texts to see what they are shown as doing and being. The answers may surprise you, and will certainly give you plenty to think about.
