Satanism is a religion founded in 1966 by Anton Szandor LaVey. Its teachings are based on individualism, self-indulgence, and "eye for an eye" morality, also drawing from the rituals and ceremonies of occultist Aleister Crowley. Employing Crowley's terminology, its adherents define Satanism as a "Left-Hand Path" religion, rejecting traditional "Right-Hand Path" religions such as Christianity for their perceived denial of life and emphasis on guilt and abstinence. Satanism does not focus on literally worshiping Satan, but, rather uses "Satan" as a symbol of carnality and earthly values, of man's inherent nature.
Anton LaVey established the Church of Satan, in 1966, and codified Satanic beliefs and practices in the Satanic Bible in 1969. According to the First Satanic Church, there are many Satanists around the world, including both members and non-members. It rejects the legitimacy of any devil worshipping Satanists, dubbing them reverse-Christians and pseudo-Satanists. Although exact numbers have never been released, it has been estimated by the church that the number of Satanists world-wide is in the tens of thousands.
