I was reading a little bit of the witches bible by I believe Janet and Steward Farrar. Some of this information is making me a little bit uncomfortable. One of the parts of the book it states that if someone breaks the laws even through torture the curse of the goddess will be upon them and they will never be reborn on earth and they are sent to the hell of the Christians. after reading that I paused and put the book down, now I'm here. I thought a Wiccan doesn't believe in a hell or even the devil in christian believes. I've heard from some other Wiccans that if a witch were to betray her coven she will be exiled from it and in old tradition sometimes killed, and I'm not even sure if that is true. So...can someone give me some clarity?
