There are so many different ways to interpret the phrase "I am a Christian" that I think you'd need to define for yourself exactly what 'being a Christian' means to you before you try to decide whether Tarot has any place in your life.
Does the Christianity of your belief system make room for any form of self reflection? Is yours an especially dogmatic faith?
As others have said, many religious organizations shun anything with even the vaguest 'occult' historical origins, and expect their followers to do the same. (even if certain aspects of the faith itself might not stand up to rigorous scrutiny along those same lines)
For me, faith is about an individual's own relationship with the divine, free will and personal responsibility being a huge part of it.
Others feel very differently, that the individual ought to surrender their their own opinions, accepting the will of the organization and those in charge.
The Bible is all about self-reflection. I don't think I'm in the dogmatic faith. I mean there are some that are, but I'm not that kind. I think people are afraid of occult, so just avoid it altogether because people hear scary stories. I want a real relationship with Jesus. Not based on other people saying things. I want the Bible to come alive to me. I want God to speak to me. I don't want to "play church." God doesn't want us to be blind sheep because if we were like that we would be so vulnerable and instead of the occult we would literally be in a cult!
