Tell them, "This here is the pure 'n primordial Primitive Baptist magick
From my point of view, a religion is a combination of a moral code, and a belief system which is necessary to do magic.
I'm glad to see you guys get it, I personally prefer to call it "white magic"...
Incantations, prayers, healing and similar stuff is what religion more or less does, this magic is contrary to black magic therefore OK to call it white magic I think.
I think there is no reason to claim incantations, prayers, healing etc. is not magic, how ever called, white or something else.
Only that it attracts millions of people IS magic and it works, we can see it works and we can hear people claiming it works on them although they don't see it as magic, they call it faith backed by miracles etc.
A true mage IMO should not say religion is gibberish, but rather should understand it, should see the potential and exploit it to boost it's own power.
Just imagine what you as a mage could do to people who believe something which they don't understand but you do.
A person with information (or knowledge) is supposed to be ahead of a person without it right?
Should be able to influence those who lack it, for it's own gain.
At least that's my understanding on how to exercise black magic, by exploiting white magic on those who don't understand the magic which they follow or practice.
