Thank you. If one was to take both this advice and the advice given about the other books, one could read all of them, and then chose to excise the elements of the ritual chapters as he see fit providing that the rest of the philosophy was adhered to in able to balance the entirety of what is being practiced.
I did not say you could excise anything from this religion.
I said you did not have to personally
use Greater Magic.
I did not say you could
deny Greater Magic is a part of Satanism for those who do wish to employ it.
Whether you can accept Greater Magic is real or useful in your own opinion is your problem.
"Squibs" and "Muggles" are welcome here too.

That Greater Magic remains a part of this religion
as a more sophisticated tool along with all the other tools that comprise Satanism is a fact.
If that tool is not one you wish to employ that is just fine.
However it is part of the toolkit, like it or not.
