Anton Szandor LaVey,

“Satan has certainly been the best friend the church has ever had, as he has kept it in business all these years. The false doctrine of Hell and the Devil has allowed the Protestant and Catholic Churches to flourish far too long. Without a devil to point their fingers at, religionists of the right hand path would have nothing with which to threaten their followers. "Satan leads you to temptation"; "Satan is the prince of evil"; "Satan is vicious, cruel, brutal," they warn. "If you give in to the temptations of the devil, you will surely suffer eternal damnation and roast in Hell."The semantic meaning of Satan is the "adversary" or "opposition" or the "accuser." The very word "devil" comes from the Indian devi which means "god." Satan represents opposition to all religions which serve to frustrate and condemn man for his natural instincts. He has been given an evil role simply because he represents the carnal, earthly, and mundane aspects of life.”
