"Wic-ca noun the religious cult of modern witchcraft, especially an initiatory tradition founded in England in the mid 20th century and claiming its origins in pre-Christian pagan religions."
Found in the built-in dictionary in my Mac.
Interesting. :] Unfortunately I'm not, but it sounds like an interesting culture.
Wicca has its roots in pre-Christian tradition and has is flowering in post-Christian thought. It's worth being studied, some rituals might be worth participating in, some symbols might be worth deep contemplation, but my opinion on Wicca depends on the Wiccan.
