The Church does not espouse a belief in Satan as an entity who literally exists, and LaVey did not encourage the worship of Satan as a deity. High Priest Peter H. Gilmore has stated "My real feeling is that anybody who believes in supernatural entities on some level is insane. Whether they believe in the Devil or God, they are abdicating reason". Gilmore defines the word "Satan" as "a model or a mode of behavior", noting that in Hebrew the word means "adversary" or "opposer", which can be regarded as "one who questions". Gilmore describes Satanism as beginning with atheism, and taking the view that the universe is indifferent: "There's no God, there's no Devil. No one cares!" LaVey sought to cement his belief system within the secularist world-view that derived from natural science, thus providing him with an anti-theistic 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.
