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.

Examining the theme of child sacrifice as a psychological challenge, this book applies a unique approach to religious ideas by looking at beliefs and practices that are considered deviant, but also make up part of mainstream religious discourse in Judaism, Islam, and Christianity. Ancient religious mythology, which survives through living traditions and transmitted narratives, rituals, and writings, is filled with violent stories, often involving the targeting of children as ritual victims. Christianity offers Abraham's sacrifice and assures us that the "only begotten son" has died, and then been resurrected. This version of the sacrifice myth has dominated the West. It is celebrated in an act of fantasy cannibalism, in which the believers share the divine son's flesh and blood. This book makes the connection between Satanism stories in the 1980s, the Blood Libel in Europe, The Eucharist, and Eastern Mediterranean narratives of child sacrifice.

The Book of the Law, the holy text that forms the basis of Thelema, was transmitted to Crowley by the entity known as Aiwass in Cairo, on three successive days during April 1904. Acting as a medium, Crowley recorded the communications on hotel notepads and later organized his automatic writing into a short, coherent document. Aiwass/Crowley presents The Book of the Law as an expression of three god-forms in three chapters: Nuit, Hadit, and Ra-Hoor-Khuit.
