In the end, nothing is wrong with creeds or beliefs as long as you stay aware of your individuality, keep your freedom and are able to enlighten and improve your own self without getting dependent from any outside influence or structure. It does not matter which God or Goddess you have, or how many of those, or if you have anything like that at all, it is completely unimportant whether you believe in the divine, or in fate and coincidence, or solely in the laws of physics.
The Tarot is valuable and suitable for any kind of person that has an inside, a consciousness and a subconsciousness. It is completely independent from any belief but the belief in your own self. (from Magick in Creeds and Beliefs)
