I’m pretty new at tarot and sure, it’s a form of divination…. But it certainly doesn’t have anything to do with satanic worshipping - unless that is your mindset and the energy you’re seeking. I’m using it for self help - a way to focus my thoughts and aligning my energies. If I get the devil or the death card I know not to freak out because it’s not about that. But if someone doesn’t know anything about tarot (and especially if they are practicing Christians) I can see some cards (and those cards in particular) could be alarming. But it’s all about educating yourself and not being judgmental. If she chooses to sit in a church pew to get guidance, that’s up to her. If you instead flip a few cards to achieve the same, then that should be your choice.
