To polytheists, the gods are sacred. But atheist Pagans don’t believe in gods. What is sacred to an atheist Pagans? Some polytheists mistakenly assume that an absence of gods must mean an absence of sacrality.
I’ve had polytheists come right out and say that, because I don’t believe in gods, then nothing is sacred or holy to me. Implied in that statement is the belief that there is nothing sacred or holy in the world except the gods. I would have a hard time imaging a less “pagan” statement than that.
Now, as far as I am concerned, you can be Pagan and a polytheist, or a duotheist, or a Goddess-worshipping monotheist, or a pantheist, or an animist, or a non-theist, or an atheist—if you want to call yourself one. I’m not interested in trying to push anybody out of the Big Tent of Paganism. But I do not understand a Paganism which cannot find the holy or the sacred in the earth or our bodies or in our relationships.
