The book Job by Robert Heinlein has an interesting slant on the whole religion thing including Satan and Loki.

Question: Is it possible that there could be no God, yet Satan would remain? Having read the Satanic Bible by Anton LaVey, it would seem that Satan needs God as much as God needs Satan! In religious lore, neither appears to be capable of making their case, prima facie. And the believer needs both so that he/she may replay, in his/her own way, the story of Job! One must be saved from the other! The Abrahamic God requires the Devil, and His Satanic Majesty must make war against God. Both are fictional characters, worthy of their places in the myths, legends and fairy tales of human history.

I really like the rabbi's take on the Adam and Eve story. Much more textured and "wise" than the simplistic one in our Bible.

It's weird for a non-believer to "believe" in another fantasy being. It seems expedient so to thumb your nose at theists. There are no "spiritual" beings. Just do your good for the sake of community. Let all religion die.

I just don't do religion. Period.

As an atheist I do not use religious words or vernacular in logo or claim to be one. It is just a fun way of getting a point across, I see that, but Satan, the devil etc are just cute bible beings. the Church of Satan in England, as I understand , used the name just to get the attention hopefully bringing people in to ask why the name.

I was quite shocked to find out that he does not appear in Judaism. So for thousands of years God did not have his arch rival. So was he invented like Moriarty for Holmes or the Joker for Batman?

A really cool hero god created, knowing he’d turn evil and such a badass!

I identify as a Satanist and am a atheist. Satan isn't a real being, but rather a symbol of man's carnal nature.

I don't identify as a Satanist, but I've read The Satanic Bible. I get that Satan symbolizes Freedom, Equality, Individuality, and Empowerment. I admire all of that. There are many more virtues that intimidate Xtians, but mostly what they fear is taking responsibility. Satanism, as I understand it, isn't relying on a "higher power" or false humility, but accepting responsibility for your own actions and their consequences without excuses.

A fun read in this vein is Satan:His Psychotherapy and Cure by Dr. Kassler J.S.P.S.

A cute little novel from some time back.

Another one is the new Tom Holt, The Management Style of Supreme Beings.

I recommend both to you.

Just because I can't pass up an excuse for shameless self-promotion:

My forthcoming novel SCAPEGOATS (Golden Fleece Press March 2018) has a role for Satan. He's the Jewish HaShatan (named Stan), in my book, he's the quality control officer. We get to see him play off against Nick, the Christian Devil, who keeps trying to shmear people for their souls.

Modern Satanism is a diverse affair. To lump them as righteous humanists or baby eating sex fiends is to graze the subject. It is somewhat amorphous in a sense, people project their default views upon it. For myself, I have little need of fictional superheros, much less new ones.

Literature nerds will have heard that name before. Some of you love him; some of you hate him. Either way you can’t deny the effect he’s had on storytelling because you’ve seen it. Youtube is full of videos pointing out how our culture’s most popular stories like Star Wars and Lord of the Rings map to Campbell’s theory. Joe was a comparative mythologist and he wrote a book called “The Hero with a Thousand Faces” in which he lays out a basic story structure that, he believed, all stories follow.

Basically the gist of Campbell’s Hero’s Journey is this: A character (the protagonist) has circumstances that send them on a quest. They find some sort of catalyst to send them in the right direction, they meet a guide, face challenges, acquire the thing they sought, change, and return having changed. That, for the most part, is every story you’ve ever read.
Yes, Satan … and Jesus Too

For people who don’t hang out with literature and are just part of modern culture it’s pretty easy to see how Jesus fits Campbell’s structure; he’s even got epicycles. Most people don’t think about it but Satan fits that too. In our culture’s prevailing mythology Satan (by way of John Milton):

1. Realizes he’s working for a tyrannical dictator
2. Rebels (the war in heaven)
3. Is cast out into an unfamiliar place (hell)
4. Meets allies and cohorts (the denizens of hell [this would be the Abyss part of Campbell’s chart])
5. Devises a solution
6. Struggles to journey from Hell to Earth
7. Finds Eden
8. Returns to god’s presence, having changed, and is therefore capable of causing change, which he does by convincing humans to eat of the tree of knowledge.
