It depends on who you ask and how fundamental their beliefs are.
I grew up in a pentacostal christian household where I went to church 5 times a wekk, spoke in tongues, and regularly saw people fall over when the pastor would lay hands on then, my parents also gave %30 of their income to the church - pre-tax.
My parents lump anything having to do with new age ideas as witchcraft, my parents are %100 against tarot cards or any form of divination because the bible says:
Deuteronomy 18:9-12 ESV / 23 helpful votes
“When you come into the land that the Lord your God is giving you, you shall not learn to follow the abominable practices of those nations. There shall not be found among you anyone who burns his son or his daughter as an offering, anyone who practices divination or tells fortunes or interprets omens, or a sorcerer or a charmer or a medium or a necromancer or one who inquires of the dead, for whoever does these things is an abomination to the Lord. And because of these abominations the Lord your God is driving them out before you.

“A man or a woman who is a medium or a necromancer shall surely be put to death. They shall be stoned with stones; their blood shall be upon them.”

And I will cut off sorceries from your hand, and you shall have no more tellers of fortunes;

And when they say to you, “Inquire of the mediums and the necromancers who chirp and mutter,” should not a people inquire of their God? Should they inquire of the dead on behalf of the living?
I think the main point with christians like my parents is they believe they have a direct line to God himself where he communicates with them and tells him what to do, so why would you need a tarot if God is so great? My mom claims to have personal promises from God that me and my brother will one day be radical christians again, she thinks its set in stone and constantly reminds me of it. How that works with the whole free will thing I dont know.
If you ask someone else though, like a more liberal christian that kinda picks and chooses which parts of the bible to follow(they all do to a certain extent), they will tell you it's not a problem, even go so far as to say God speaks to you through the tarot. But to me, I could never be a christian and use the tarot at the same time, the christian worldview at least the one I grew up in, is diametrically opposed to new age stuff.
I mean if you claim to be a christian, and you claim to have the holy spirit in you and believe that the bible is the God inspired truth, a tarot shouldnt be able to compare to that if thats really real for you. The bible says "The steps of a righteous man are ordered by the lord." It's clear that God is supposed to give you direct guidance by you reading his word - the bible - at least from a theological standpoint. Why would you need an oracle when you are getting the direct words of God supposedly? The bible says man does not live by bread alone but by every word that proceeds from the mouth of God.
When the bible was written paganism was in full force too, so if God really wanted you to use divination, dont you think it would mention it in a positive light at some point? Witches and fortune tellers are almost as bad as homosexuals in the bible. I don't see how the bible and tarot can really be reconciled, and this is coming from someone that completely rejects the bible, but used to believe it wholeheartedly and live it to a fanatical extent.
Are you just holding onto your christianity in namesake only?
Just my two cents, no offense to anyone that does not agree.
