there are a lot of people who are afraid of any form of divination because they do not understand it. people fear what they cannot understand. it's a sad thing that they do not give it a try, and test it for themselves, with a level headedness. but then this is the nature of man.
I wouldn't take it too personally. But, I would be careful as to when and where I used the cards. I'm careful to where and when I use it and to whom I tell about my abilities. I have to fear the Catholic church, because as a practicing Catholic, I could be instantly excommunicated from the church and no longer able to receive the sacraments. I'm not the best practicing Catholic--truly, but I not want to be excommunicated, as I do still go to church now and again and wish to receive the sacraments.
I do not think that any form of divination is the act of the devil. it is a gift given to us by God--(or, depending on your belief, Goddess/the Universe, ect). For every quote found by man in the bible to speak of its ill, there is one that will support the fact that these abilities of some of us is a gift from the Holy Spirit and God himself.
In the bible, Abraham was about to sacrifice his son--luckily an angel came to stop him--but why wasn't he considered an abomination? first of all for the wanting to sacrificing of his son, and then for confessing that an angel came at the last moment to save the son! both would speak of Abraham being tied to devils work, if you listen to such people.
even some of our saints and people alive today are considered good holy people and they have extraordinary abilities. One famous one is Padre Pio. he was known to levitate and could 'read souls' as well as bi-locate. he was also a healer. so, was he this holy man? or was all this the work of the devil? true, the Church didn't quite know what to think of him at first and did their best to hide him. A past priest of mine from years ago had met him a few times--and thought he was a fake. But, Padre Pio became very famous and made a saint. he is very much revered today.
it use to be a sin for women to wear pants. even frowned upon if we cut our hair short. for men to wear jewelry, such as earrings. for women to smoke, drive, or be out alone without a male escort. to dance, alcohol was the devils work and sloth. now pretty much the norm in today's world.
perhaps in time, divination as we know it today will become more acceptable. only time can tell. meanwhile, just be careful where, when and whom you share with.
