I have also given this much thought. When I first started my journey with tarot, my sister told me that this was against the catholic faith. My neighbor invited mt ae to join his church, when I told him I was in to tarot & asked him to mention this to his pastor......never heard from him again...hehehehe
I feel comfortable with the many readings I have gotten from mediums & grateful. BUT if I have any doubts on the honesty or integrity of someone....I let it go and move on. I truly believe we all haVE THE INSTINT
to know what is true for each of us. Great question tho !!!T
