Q. What are the commandments in Wicca?
A. This may come as a shock, but there are no rules in Wicca. We are not bound by some official list of commandments that tell us what is allowed and what is not. Considering these types of rules in other religions are always being debated/argued over, it's likely for the better.
Many people feel that a lack of rules means we all run amok in our lives, committing all kinds of terrible acts. Believe it or not, it is possible to know right from wrong on your own without having it laid out in front of you by someone else.
The last line of the Wiccan Rede is the closest thing we have to a commandment: "An it harm none, do what you will". Not all Wiccans follow this to the same degree, but it's generally interpreted that anything is OK as long as no one is harmed.
Who needs more rules than that?
