Frater Benedict
In some forms of Wicca it can be seen as a religious implement and used in ritual, but it doesn't help form the basis of the belief system.
The bit about 'doesn't help form the basis of the belief system' is also true about Valentin Tomberg's Roman Catholic variety of Hermeticism and Papus' variety of Neo-Gnosticism. Both appreciated tarot, and used it to illustrate each of their philosophies respectively, but tarot readings didn't became a part of Mass, if you know my drift.
