The Satanic Kerygma: The Book of Godless Satanism

So that the Satanist, having rejected belief in imaginary gods, would believe in the divinity of the reason of the human animal, and in an abundant, godless life before death, and that, knowing it to be the inevitable end, he would have eternal peace after death, united forever with the power of the Infinite, the only godless reality that exists.

Or even more succinctly:

So that man so loves the godless Satanic world that he rejects the belief in delusion, which takes away the power of the divinity of human reason, and so that he does not become a slave to the fear of hell, but has a godless life abundant before eternity in the peace of death.
