Well….the word “cult” means different things in different circles. In cultural anthropology the word refers to ‘a religious group held together by a dominant, often charismatic individual, or by the worship of a divinity, an idol, or some other object.’ Many traditions of Wicca can fit THAT definition.
However, most people mean cult in the sense of an exclusionary organization that separates adherents from their previous lives, friends and family. Usually these are easy to get into and hard to leave, and are often psychologically, sexually or physically abusive. I’ve yet to see a legitimate, lineaged Wicca tradition that fits this definition.
IN GENERAL, traditional Wicca covens encourage healthy home lives and friends and family outside the coven. The coven takes time to enter and initiate, but it is easy to leave, and leave for good. A popular elder of a number of Pagan traditions, including Wicca, developed a tool for evaluating groups and the cult danger they present: The Advanced Bonewits’ Cult Danger Evaluation Frame.
As for Satan/The Devil, anyone who has actually studied this Judeo-Christian myth knows that they are two completely separate concepts. Ha Satan is a *role* that is very important in Hebrew lore. Satan tests YHWH at YHWH’s behest. “The Devil” is a medieval Christian development, and is often conflated with imagery of Pagan gods.
Many Wicca work with a horned, cloven footed deity form. We certainly don’t think that our God is “the devil” though.
