"The Bible texts you mentioned can be interpreted by several ways and I can't use my reason to select the best interpretation. I don't need to accept things that are not clear in the Bible."
This is not true. I am sorry, but I have to say that you are being dishonest.
The Bible texts regarding spiritism (not all were included in my comments above) are very clear, unambiguous, unequivocal and explicit regarding the dangers of and penalties for engaging in spiritism.
".....I can't use my reason to select the best interpretation"
BTW, where does your reason come from? Your immaterial soul or your brain?
