Thirteen,
This is so insightful! And I can say from personal experience that it does happen just like you say.
And, thinking out loud here, I suppose that would imply the other direction as well? A strong, dogmatic, ridgid moral code actually maybe has as its shadow the Devil--even creates it. Like a "Don't think of a monkey" sort of thing. I know that when I was Catholic (strict, Tradtionalist sort of Catholic--went to confession every week, prayed Rosary every day, etc.) that I regulated my thoughts and actions and senses very carefully--or at least I tried. And as a result, I think that it more or less created an unhealthy relation to certain things that wasn't naturally part of my make up.
When I stopped worrying about those things (and stopped being Catholic) the whole situation changed and resolved itself on so many levels.
And the black mass and satan worship come to mind. Possibly a creation of the Church, indirectly at least? I'm also thinking of the famous witch hunters document, too, and some "Demonology".
Anyway, just some thinking out loud. Certainly, many many main-stream religious people avoid this, and are genuinely spiritual and healthy and leading wonderful lives directed towards the divine. No question. Which brings to mind one of the things I dislike about the Robin Wood Hierophant. She sees this card in a negative light and it shows. The Hierophant looks constipated, not wise. Oppresive, not beneficient. And so it can be, in a negative aspect, but there is also the positive. Which I also have first hand experience of, from being a Catholic. When I stopped being Catholic, and lost my daily practice, it was a lot like throwing the good out with the bad. I lost a lot for a time, until I found a new path.
OK. Cutting myself off now.
p.s. I love what you've written about the Tarot, Thirteen. Thank you so much for all that you have given us!!!
