On this Walpurgisnacht, Anton Szandor LaVey establishes the Church of Satan at the Black House in San Francisco, California. Anton Szandor LaVey will remain the High Priest of the Church of Satan until his death in 1997.
The Church of Satan does not involve worshipping or even believing in any sort of devil or other supernatural entities. According to Peter Gilmore:
"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. ...
Satan is a model or a mode of behavior. Satan in Hebrew means 'adversary' or 'opposer'; one who questions."
