Hello, alchemist1248. I'm sorry to see you getting so many negative & even antagonistic responses here. I adhere to no 'religion' myself, but understand your question (I think.)
Yes, I too think it would be nice if we could express some kind of consensus about what we 'believe in' regarding our various Tarot practices. Perhaps, indeed, there are none at all - though I would consider that unlikely.
At the very least, we surely share a belief / hope / expectation that we can get 'answers' or new 'takes' on questions & situations ... even if we differ hugely in where we assume those answers come from ...
Our own Unconscious? The Jungian 'Collective Unconscious'? Archetypes endemic to our cultures? God(s)? The Tao / Universe / Akasha? Our 'Higher Selves'? Angels / 'spirit guides' / the ancestors? 'All-That-Is'?
Personally, I have still not yet arrived at any definite conclusion(s) but am fascinated and always considering the above as possibilities, with an open mind.
I too would like to hear more serious answers or personal beliefs, which inform & enrich my own seeking.
So far, all I can say for certain is that we Tarot readers are hopefully & expectantly searching for answers. From whence? Who knows?
NB: All of my above post refers to religion, in a way. If by re-ligion we go back to its original meaning or re-binding or 'tying together again' and re-joining some vital link that has been lost. I see re-ligions as systametised attempts to re-bind us to our Higher Selves ... our past cultures ... to our God(s)/Goddess(es) or however we envisage the Divine ... and to each other, in community. Also - to other communities in our human family.
Tarot could possibly do that, within its small community, if we so chose. This need not impact negatively on our sense of individuality & personal agency, depending on how it were framed.
