About the Official Cult of Cthulhu
he Official Cult of Cthulhu is an occult religious organization based on the fictional writings of HP Lovecraft, the teachings of Anton Szandor LaVey, and finally the refinement of Venger Satanis. To be very clear, yes this is a form, or denomination of Laveyan Satanism.
So what is this Cult about? The original concept of the Cult was Cosmicism. Cosmicism is a term coined by H. P. Lovecraft, the philosophy of cosmicism states "that there is no recognizable divine presence, such as a god, in the universe, and that humans are particularly insignificant in the larger scheme of intergalactic existence." The most prominent theme is humanity's fear of their insignificance in the face of an incomprehensibly large universe: a fear of the cosmic Void.
The truth is that isn't what the Cult is about at all. This Cosmicism is Atheist rubbish first espoused by a fearful man who never understood the nature of events that inspired his writings. It's a sad truth, but a very accurate one, especially where a religion is concerned.
The Cult of Cthulhu is a Satanic Initiatory Organization, that uses the Lovecraftian Mythos, as a theme for its spiritual and magical workings. As we are a religion, we are by default not Atheists, even if at times we may sound Atheistic. Remember that contrary to Lovecraft's Cosmicism, we are first and foremost, SATANISTS. It's just instead of horns and pitchforks with lots of fire, our devils often have tentacles and lots of green slime.
Oh yeah and one more thing. We actually do believe in a very real Cthulhu and Great Old Ones. Very long story, maybe we might explain it another time.
