Church of Satan

The Church of Satan (CoS) is a religious organization dedicated to the religion of Satanism as defined by Anton Szandor LaVey. Founded in San Francisco in 1966, by LaVey, it is considered the "oldest satanic religion in continual existence", and more importantly the most influential, inspiring "numerous imitator and breakaway groups". According to the Church, Satanism has been "codified" as "a religion and philosophy" by LaVey and his church.

Founded in an era when there was much public interest in the occult, witchcraft and Satanism, the church enjoyed a heyday for several years after its founding. Celebrities attended LaVey's satanic parties and he was invited on talk shows. His Satanic Bible sold nearly a million copies.

LaVey was the church's High Priest until his death in 1997. In 2001, Peter H. Gilmore was appointed to the position of high priest, and the church's headquarters were moved to Hell's Kitchen, Manhattan, New York City.

Members do not believe that Satan literally exists and do not worship him. Instead, Satan is viewed as a positive archetype embracing the Hebrew root of the word "Satan" as "adversary", who represents pride, carnality, and enlightenment, humanity's natural instincts which Abrahamic faiths have wrongly suppressed. According to High Priest Peter H. Gilmore, Satan is "a name for the reservoir of power inside each human to be tapped at will" . In LaVey's book, The Satanic Bible, the Satanist's concept of a god is described as the Satanist's true "self"— a projection of his or her own personality, not an external deity. Satan is used as a representation of personal liberty and individualism.

The Church dismisses the idea of a “Satanic Community” and does not share membership lists with its members, arguing members are "radical individualists" who "may share very little in common beyond" being Satanists. The Church rejects the legitimacy of any other organizations who claim to be Satanists. 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."
