self-indulgence was a desirable trait, and that hate and aggression were not wrong or undesirable emotions but that they were necessary and advantageous for survival. Accordingly, he praised the seven deadly sins as virtues which were beneficial for the individual. The anthropologist Jean La Fontaine highlighted an article that appeared in The Black Flame, in which one writer described "a true Satanic society" as one in which the population consists of "free-spirited, well-armed, fully-conscious, self-disciplined individuals, who will neither need nor tolerate any external entity 'protecting' them or telling them what they can and cannot do." The sociologist James R. Lewis noted that "LaVey was directly responsible for the genesis of Satanism as a serious religious (as opposed to a purely literary) movement". Scholars agree that there is no reliably documented case of Satanic continuity prior to the founding of the Church of Satan. It was the first organized church in modern times to be devoted to the figure of Satan, and according to Faxneld and Petersen, the Church represented "the first public, highly visible, and long-lasting organization which propounded a coherent satanic discourse". LaVey's book, The Satanic Bible, has been described as the most important document to influence contemporary Satanism. The book contains the core principles of Satanism, and is considered the foundation of its philosophy and dogma. Petersen noted that it is "in many ways the central text of the Satanic milieu", with Lap similarly testifying to its dominant position within the wider Satanic movement. David G. Bromley calls it "iconoclastic" and "the best-known and most influential statement of Satanic theology." Eugene V. Gallagher says that Satanists use LaVey's writings "as lenses through which they view themselves, their group, and the cosmos." He also states: "With a clear-eyed appreciation of true human nature, a love of ritual and pageantry, and a flair for mockery, LaVey's Satanic Bible promulgated a gospel of self-indulgence that, he argued, anyone who dispassionately considered the facts would embrace." A number of religious studies scholars have described LaVey's Satanism as a form of "self-religion" or "self-spirituality", with religious studies scholar Amina Olander Lap arguing that it should be seen as being both part of the "prosperity wing" of the self-spirituality New Age movement and a form of the Human Potential Movement. The anthropologist Jean La Fontaine described it as having "both elitist and anarchist elements", also citing one occult bookshop owner who referred to
