Along those lines, most bands of this type have adopted variations (with varying degrees of authenticity) of pagan beliefs and traditions, believing them to face destruction by Christian beliefs.
Satanism is a religious and philosophical movement whose adherents recognize Satan as an archetype who all humans have some characteristics of, and Satanists celebrate aspects of human nature represented by the Satan archetype. Many Satanists do not worship a deity called Satan, or one by any other name. Unlike many religions and philosophies, Satanism generally focuses upon the spiritual advancement of the self, rather than upon submission to a deity or a set of moral codes.
