Book excerpt: This is Laurence Gardner's final book, written shortly before his death in 2010 and is the accompanying book to his Origin of God (published 2011 by dash house publishing). Together with Origin of God, this book outlines an irrefutable and searing indictment of conventional belief and exposes the evils and absurdities perpetuated over the millenia in the name of Christianity. In Revelation of the Devil, Laurence Gardner traces the history of the Devil, from its roots in Mesopotamia and the Old Testament all the way up to the modern world of today. Travelling through the New Testament, as well as the Koran, and then passing in turn through the Inquisitions, the Reformation and the Enlightenment, he unmasks what he has called "the myth of evil and the conspiracy of Satan." For nearly 2,000 years a supernatural entity known as the Devil has been held responsible by Church authorities for bringing sin and wickedness into the world. Throughout this period, the Devil has been portrayed as a constant protagonist of evil, although his origin remains a mystery and his personality has undergone many interpretive changes, prompting questions such as: If God is all good and all powerful, then why does evil exist? How can it exist? If God created everything, then where did the Devil come from? If the Devil exists, then why does he not feature in any pre-Christian document? Revelation of the Devil follows the Devil's sinister history, in the manner of a biography, from his scriptural introduction to the dark satanic cults of the present day. In a strict chronological progression, we experience the mood of each successive era as the Devil's image was constantly manipulated to suit the changing motives of his creators in their bid for threat-driven clerical control.
