I agree with you totally, I think if youre going to call on the deities for power and guidance, you have to (at the very LEAST) believe in them???! If you dont, youre just ''going through the motions'' and not actually getting anything done. Youre work would be for naught if you did a spell but didnt think the God/Goddess youre asking guidance from existed at all...
I mean, I understand people who dont choose to ask for power from a deity, and I know some that dont believe in the deities and just do Energy work as you say, and thats fine. Just dont start naming off gods and goddesses names just because they're handy and add to your ''mystery''...
lol... what silliness.
