What does god think about witchcraft?

As most of the practicing witches I know are polytheistic, I'd have to say no.

Not only does the Craft not go against god, it works with many of them, goddesses too.

Ours tends to be an inclusive spiritual path, we respect other belief systems, we just don't follow all of what others say.

This does not mean however that there are not other views. Some spiritual paths believe that their way is not only the right way, but the only way so they tend to have a problem with the Craft.
