LaVey was an atheist, rejecting the existence of all gods. LaVey and his Church do not espouse a belief in Satan as an entity who literally exists, and LaVey did not encourage the worship of Satan as a deity. Instead, the use of Satan as a central figure is intentionally symbolic. LaVey sought to cement his belief system within the secularist world-view that derived from natural science, thus providing him with an atheistic basis with which to criticize Christianity and other supernaturalist beliefs. He legitimized his religion by highlighting what he claimed was its rational nature, contrasting this with what he saw as the supernaturalist irrationality of established religions. He defined Satanism as "a secular philosophy of rationalism and self-preservation (natural law, animal state), giftwrapping these ideas in religious trappings to add to their appeal." In this way, LaVeyan Satanism has been described as an "antireligious religion" by van Luijk. LaVey did not believe in any afterlife.
