Lois Bourne, author of the incredibly warm and informative “Witch Amongst Us” gave a very simple answer to the question “how can you tell if someone is really a Witch”?
According to Lois, one must determine whether or not he/she can really do magic. Since Witches live by magic and for magic (or Magick, as some traditions write), the ability to effectively cast spells is, I’m sorry to say, a fundamental requirement. Do Witches cast spells for others? For cash? Should they? These are all hotly debated ethical questions in the Witchcraft community.
