Dr.Levay, spirit guide his soul, is dead. The Satan of the bible believes in god, jsus, etc. Whatever you want to call him Beelzebub, Atrayus, Lucifer, he is destined to lose in the bible. If Satanists followed this Satan, this interpretation of Satan, it would be a pointless religion. As a member of the church, I can assure you I have nothing wrong.
Being an ex-christian myself, I could probly school many of you on christianity. In any case, Antioch to answer your question, jsus did not define a christian as someone who just believes in god and jsus. "Be a light amongst the world" "Turn the other cheek" "Let your good deeds shine before others". Before I left christianity altogether I ascribed to the views of a growing movement in the xtian community that believed that one must live like jsus to be with jsus. The basis of this belief statement is the gospel of mark, in which jsus stressed living your life as a positive force in the world, as opposed to the other gospels where different aspects were more stressed such as the chronology of jsus' life, performed miracles, etc.
Contrary to popular belief, it was mark, not paul, who wrote most of the n*w t*stam*nt, and thus more creedence is given to his view on xt. jsus did not stress just belief as a means of achieving heaven. One must progress, and do well to the people and the world around you, such that people see your life and say to themselves that you are set apart from them. If one is supposedly xtian, yet does not become a better person in the course of his life, does not make a conscious effort to do good to the world around them, one will not reach heaven, according to the 'life' theory of christianity, as opposed to the 'say jsus is your bla bla' and you will go to heaven theory. This is how I say one could be a xtian by good works.
Take the example of Ghandi. xtians believe their god is just, right? Ghandi grew up in a place that did not support mainstream christianity. He was likely not preached the 'good news', yet because of the life he led, a xst-like life, the quality of living improved for thousands or millions of people. Would a xtain believe would Ghandi be denied access to heaven, simply because he did not claim to be a xtian? He led a life closer to jsus than many xtians will ever, a xst-like life, that made the world a better place, he 'shone a light of goodness', through his belief in non-violence he triumphed over a military and helped the lives of his while nation. So would you believe god is going to turn him away at the gates? That's where I come from with the 'xst-like life' example, that some people lead lives closer to the teachings of jsus than many xtians.
Anyhow, I'm digressing. The Church of Satan does not believe in the bible, we do not follow an angel of heaven that was cast out. We believe all humans are living in suffering, a life of torture, a 'hell' if you will. We worship Satan, but we believe Satan is the only God, a force all around us, that flows through everything.
We are our own Gods. The power we hold to change our reality, and to reach a state of power through release of rules and hindrances in our own lives, that is the power we seek. We dont believe anything about xtianity is true.
Why do we call ourselves Satanists? Yes, it is true, Satan is a term that came from the bible, but in all world literature, there is no force more expressive of our beliefs than the Satan from the christian bible. Add this to the fact that Satanism came out of America, where the dominant repressive religion is christianity, and thats where we get the name 'Satanism' from. Many of our symbols and ideas are taken from bible verses, but many are not. Since Satanism was a religion created out of the beliefs of just one man, it was a mix of concepts and ideas that held to a vision.
If Satanism came from China, for example, the name might be derived from an 'evil' force in Buddhism, or if it came from the Middle East, the name could come from a subversive entity in Islam. It's all a matter of source and perspective.
Worship the Satan from the xtian bible? Hah. What a laugh. Who the fuck would want to jump on a falling ship like that? "Hey, lets all worship an entity that is doomed to fail"
That is not Satanism at all.
