My opinions on that is that you will get out of it what you put into it. If you have some kind of evil intent while doing readings it could in theory come out in your answer. After all, they are on one level connecting with your subconscious.
I imagine that is a very rare situation. I have myself never had anything like that. All my decks give me very spiritual enlightening answers.
Any tool can be misused. As they say you can use a hammer to build a beautiful home or to hurt someone. Depending on intent. I have heard some people try to get the answers from some spirits of some kind, evil or otherwise. I can tell you I have no intention of ever doing so.
Agreed, the cards themselve are just cardboard, the power is all in you. The cards just focus it. What you chose to do with your inner power and how you chose to use it is in your hands alone.
For myself, yes I believe in G-d, and I also believe that my answers come from that source. When I do a reading, it is specifically to help someone solve a problem that is bothering them, myself or someone else. I use Tarot to help people live their best lives, and I very much presume that is what G-d wants of us too.
Also, I tend to actually ask for the answers that will most help me help this person, right before I start a reading. And if I ask it is G-d who I am asking. And in fact even before that I tend to do a short medition on my scented candle I always light before I start, to clear my mind. It is a meditative kind of prayer thing. In that sense I would not say Tarot replaced my meditation or prayer practices I had. It just incorporated itself into that and became part of all that.
I know G-d wants us to live our best lives and help others. Tarot also is a way for me to very much connect more to others and the universe. It has made me a much more spiritual person than I was before. And given me a much deeper understanding of the level of the beauty and depth of this world we live in. I cannot believe that G-d would have a problem with any of this. And in fact I do sense he wants me to be into Tarot. And even seems to be guiding my choice of which decks are best for my future.
There was once a deck I wanted to by very much online, and I kept trying to pay and the online system would not work. I tried for hours, and coudl not pay. The next day I came on and found something better suited to me. For me I do not beleive any longer in coincidences, so I think that that was the universe/G-d trying to lead me in the right direction and tell me that one would have not been good for me. Now while I will likely never know why, I do trust in the process. And I do find if anything at all Tarot has made me feel much more connected to G-d.
So is all this something he would have a problem with? I can't imagine that it could be.
