I used to be into satanism and then became christian. The church of satan does not believe in satan the being, but in the representation of what satan stood for. They call themselves the church of satan simply because their doctrine is opposite everything christianity. For example if you read the book "the satanic bible" by anton lavey, you would see the first satanic statement (Satan represents indulgence instead of abstinence) as the opposite of what christians call sin. The laveyan satanists believe that sin is an instinct, as greed appears on a child naturally, and that greed teaches us to work harder. So the big point they are establishing is that sin is merely what they call instinct for in their perspective the human is only an animal, but greater for it is above in intellect so on and so on. They do not believe in heaven or hell, they say earth is the best life so live it up. They call dreams of heaven foolishness, because you deny your natural "instinct" of flesh "animalistics" Which are merely traits of human. The christian believes that these are sins which came through adam, and the reason we must deny it is because the wages of sin is death, and these sins are indeed fleshly, but not of spirit. To the satanist the flesh is alive and the spirit dead, and to the christian the spirit is alive and flesh should be dead. Yet the two war against one another. And as for sacrificing, some satanists put it into their daily belief, and some don't. The rules for a satanic sacrifice is simple, dont sacrifice animals, what did they ever do to you? If you see someone that does it is not a laveyan satanist, for it says in their bible why hurt the innocent animals. THe satanist believes that telepathic spirits will give you a surreal experience in death upon yourself in which the throes of life which you go through will open your mind to that spirit, because a sacrifice is needed to balance what the spirit wants to give you. their is a rule that if a satanist wants to physically sacrifice himself, he can, but it is neither encouraged or banned for the satanist. the basic belief of psychic vampires is a "vampire" is someone who comes along and drains your energy, your money, your time and gives you nothing back. you are instructed to hate these mooches if you are a satanist. They also believe in vengeance and if someone strikes you on the right cheek you bash them on the other, which is contrary to what christ calls you to do. basically because every rule in satanism is pretty much the direct opposite of christianity, anton lavey said, we stand for all satan stood for, even though we don't believe in satan, but the name is symbolic to them. Satanists worship themselves, not any higher power, the opposite of christianity. That is all i will say for now.
