Despite my glowing comments about Pelland's religious story Immortal Sins, I really disliked this one.
I'll admit, I thought the immediate reveal of the burning bush was pretty hilarious and quite memorable. The rest I didn't really care for. There's no clear reason why she's the one who gets to be the vessel of God. The apparent moral: the only way for a woman to end up in charge is to get alone with the man in charge and then drop her pants. And, if you ignore that unpleasant apparent moral, then the more overt moral is that the Catholic church makes absurd rules that are clearly not from God, such as only men being in the clergy. And, even though I agree with that, the message was delivered with the subtlety of a steamroller.
If this had been a flash story that showed a reveal of the bush and then some short summary of consequences it would've been hilarious and may have been one of my favorites as a joke story that made you think about religion. But the joke went on too long, and just kept pounding at its message and in the end I didn't care for it overall.
