Unlike other religions, based upon correct belief, ours is a methodology that allows the Natural World to grant these experiences from which one builds their own belief. Religious Witchcraft is based in Nature Theology. As much as definitions of a Witch would lead one to believe otherwise, a Witch does not believe in the supernatural, for in their experience, nothing exists that is not of the natural order of things.
As for what constitutes the natural order of things? Well, no two Witches will give quite the same answer. My own answer is a simple one. In short, if it exists then it is of the natural order of things. Amazingly though, when Witches gather and compare notes, they find that the stories of their experiences to be too similar to discredit as the fantasies of the individual alone.
The details and interpretations of experiences vary, and because of this there are many forms that Religious Witchcraft takes. Each in its own way is like a painting revealing the world, the end result is different but each shows the landscape through which the Witch travels.
