Many new Wiccans, and some non-Wiccan Pagans, are initiatedwith the cautionary words from their elders, “Ever mind the Rule of Three!” This warning is explained to mean that no matter what you do magically, there’s a giant Cosmic Force that will make sure your deeds are revisited upon you threefold. It’s universally guaranteed, some people claim, which is why you better not EVER perform any harmful magic… or at least, that’s what they tell you.
However, this is one of the most highly contested theories in modern Paganism. Is the Rule of Three real, or is it just something made up by experienced Wiccans to scare the “newbies” into submission?
There are several different schools of thought on the Rule of Three. Some people will tell you in no uncertain terms that it’s bunk, and that the Threefold Law is not a law at all, but just a guideline used to keep people on the straight and narrow. Other groups swear by it.
