Short answer: no. Since atheism is a complete rejection of anything supernatural.
No, dude. Theism is a belief in god(s); atheism is the absence of theism. Atheism is not the "complete rejection" (whatever that means) of anything supernatural. Atheism isn't necessarily the complete rejection of anything, besides the complete rejection of theism (definitionally).
An atheist can believe in witchcraft, ghosts, magic, etc. There isn't an atheist Pope who will atheist-excommunicate them for doing so.
I get the impression that Richard Dawkins would like to be the atheist pope if there were such a thing.
