Are these the books Joel's ministry follow? Did Joel read these books himself?
no idea, but many people these days follow the philosophy "do as thou wilt"
I'm curious of what teachings of his church coincide with these literary works.
And are these books Satanist per say?
yes
When I hear the word Satanist, I imagine people who knowingly worship Satan
(there's no such thing as unknowingly worshiping someone).
i disagree
Are these people worshipping Satan or merely being deceived by Satan (which I imagine can occur without their knowing)?
(who are "these people"?)
I'm also curious if these are the same books Mary was referencing, or if she had other books in mind. Is she not talking about The Church Of Satan, the political organization that strives for separation of church and state? Sorry, I'm wondering because even though I find Joel quite disagreeable, I don't see any evidence that he worships Satan and reads books about Satanism, or the books you referenced, the former which has nothing to do with Satan (the Egyptian gods may have been false gods, but they aren't Satan).
It's wrong to lie, even if it's about people we disagree with. No matter how detestable they may be. For if a person is truly at fault, then there is no need to misrepresent their dishonest position, for the dishonesty should speak for itself.
