I've been reading on Satanism quite a bit, and I consider myself to be a Satanist largely. But Luciferanism is a bit harder to find information on. I read some of the threads around here and at one moment I think "Oh, ok Luciferanism is sort of like theistic Satanism" but then I remember that there is theistic Satanism. So in how many ways do Luciferanism and Satanism differ (besides for the fact that Lavey is the creator of modern satanism)
Please, cleanse my ignorance.
Ignorance is natural when approaching a new subject. You will find that Satanists are not the monster that pop culture makes them out to be, I like that they do sometimes, but that's not what we are 24/7. Ignorance is also not stupidity, stupidity is denying ignorance of a subject when ignorance is implied. You are very smart to come to a satanist and ask, rather than a Christian or Jew that will only tell you from their superstitious slant.
LaVeyan Satanism is very effective. Logic is the utmost decider of what is "real" and what is not. Satan is the opposer and accuser of White Light Religious self-deceit. Luciferianism is effective as long as we don't allow out misunderstanding of the natural world, to lead us in unwisdom and self-deceit.
"The lie that is known to be a lie is half eradicated, but the lie that even intelligent persons accept as fact-the lie that has been inculcated in a little child at its mother's knee is more dangerous to contend against than a creeping pestilence!" -The Book of Satan 1:14
Lucifarian philosophy is good as long as we don't breach the lines of faith based theism. There is no evidence that Jesus, Buddha, Satan, or Lucifer exist as external beings. Satan is the opposer of faith based fabrications YHWH, Jesus, Miracles, External realms of existence.
Satanists observe Satan as the dark force of nature that the Satanist taps at will to live a vital life, free from religious guilt and self deceit. The Force is like entropy or gravity, not like some spiritual force that only people's empirical observations (which differ from person to person) can see. Those spiritual experiences, so many people use as reasons to believe in theistic forces, are often physiological and environmental misunderstandings.
Luciferianism is a more spiritual side of Satan, sometimes viewing Lucifer as the more justice and light side of life where Satan is the rebellious symbol against dogma. While this is okay to use, Lucifer took the name Satan (mythologically of course) because he opposed The Jewish god's skewed sense of justice, he opposed god because god threw him out heaven, like a tyrant would, rather than explain himself. God obviously did the same thing to Job, he failed to answer Job's question, as to while he was a test subject for god's will and power, he just told him that he was ignorant of god's power and he will never understand. Then he bribed job to keep his mouth just by giving him everything back but double.
To the Satanist, Lucifer and Satan are the same thing. Mythological beings that reflect philosophical values with in our religion. We don't worship The Devil or Satan, as The Devil is a bad description for an opposer. Devil means great deceiver in the greek, not opposer or one to question, it has no relation to the meaning of the name Satan. Christianity, Judaism and Islam relate the two names because they see people who have the balls to question religion as deceived or deluded to not take existence of great creators for face value (faith).
Satanists are satan's we are opposers and accusers of self-deception in religion and social society. We are above the "herd mentality" that Fredrick Nietzsche observed in White Light Religions and in societies deceived by convieint fads and cliques that maintain more control over their lives than they do.
If Satan opposes such a belief in gods, or external beings because that is what the god of the Bible, Quran and Tanakh was, then Theistic Satanists are only Heretical Christians, Jews and Muslims. They are also believing in a god and assuming that unexplainable stimuli are supernatural things. Magic is a natural force will and power of the human being, not of a god that opposes gods, that is a contradiction.
