It is as solid and real and valid as explained in The Satanic Bible and the Church of Satan
website (pay close attention to the "Theory & Practice" section of the website)....it seemed everyone was looking for someone to tell them how to live. Is this not what Satanism does?
No. There isn't anything in The Satanic Bible or any other Satanic writing that remotely suggests this.
The Satanic Bible has a chapter called Wanted- God Dead or Alive (as I'm sure you already know) my understanding of this chapter leaves a very open interpretation.
No it doesn't. This chapter cannot be more straightforward and direct.
God does not exist, god is a man made artifact, the Satanist is her/his own God, meaning, among other things, a Satanist is responsible for themselves in all aspects of life.
The only thing a Satanist worships, if at all, is life itself, and themselves.
