Possessed by Satan is an in-depth discussion of possession: what it is, how it is verified, and how it is overcome. The author is an acknowledged expert in the field and bases his study on the Roman Ritual of exorcism which has evolved over a 1,500 year period. The approach is chiefly historical. His examples are drawn from documented cases that have been accepted by the Church as genuine possession, as well as testimony from the Scriptures.In a conflict-ridden age, often filled with despair and faithlessness, Possessed by Satan reaffirms the ultimate powerlessness of Satan in the face of Good, as it offers the reader much-needed light on a phenomenon of increasingly serious inquiry.
