Christopher Partridge and Eric Christianson have edited a volume that explores the influences of Christian demonology on the new religions and popular culture in the book The Lure of the Dark Side: Western Demonology, Satanic Panics and Alien Abduction (Equinox Publishing, 2008). The book was recently reviewed here with an excerpt from this review below:
"Although the subtitle promises to be a survey of western demonology, Satanic panics, and alien abduction Partridge’s survey is more a deconstruction of UFO religion and the eclecticism of its sources. The extra-terrestrial religious ideas may have had their origin in theosophical strains of Eastern thought but the religion of groups such as Heaven’s Gate is in fact more rooted in western demonology, specifically the adaptation in popular culture of the idea of the nephilim (Gen 6: 1-4). In the space of a short lecture Partridge has done a good job at delineating the dialectic between theory and popular culture and so, from the perspective of those interested in alternative and fringe religions the author has done a good job in charting the field. However, for those like my self who do not spend much time thinking about the theology of the Raelians a more interesting phenomenon - why as the stranglehold of ‘Christian’ understandings of the world been dissipated have these religions relied on parodies of Christian demonologies. In understand that popular culture is tapping into a latent understanding in invoking such ideas from Christian sources - however, the fact that the UFO religions have followed suit strikes me as a far more interesting question both theologically and sociologically."
