I'm a pagan.
That's a wonderfully ambiguous term that can mean anything you want it to mean - there's as many different kinds of contemporary paganism as there are practitioners, from hardcore Greek or Roman reconstructionists with degrees in ancient history, to New Agers who grab a bit from here and a bit from there, mix up a Celtic god with a Roman Goddess and a Native American ritual they read in a magazine. (I personally don't like the latter, I think it shows disrespect to jumble things up together like that without researching them, but if it works for others, they're welcome to it.)
If I had to pick a definitive category to describe myself, I'd probably be a Celtic reconstructionist. But there are things I believe which I know don't gel with that tradition - like the idea that all the different deities are ultimately representations of the one entity. I don't presume to know what that entity is, and wouldn't even go so far as to call it a being. I recognise that my belief system's one of many, and no more or less true than any other, it's just the philosophical template I happened to choose as the interface between me and the divine. I enjoy the research, the rituals and the myths and legends.
And no, that doesn't mean I belive there really are Gods and Goddesses sitting up in the clouds drinking wine and chucking thunderbolts around, any more than Christians believe God is physically sitting up there in a geographically definable place called Heaven, looking just the way he's described in the bible when he handed over the commandments. As far as 'commandments' and rules for living, I just go by the one Ultimate Commandment (also called the Wiccan Rede and lots of other names):
Harm None
Think about it, it really does cover everything, doesn't it?
