I'd have to think about my answer, but I got a chuckle out of some of the options. I got a good laugh out of Meg's comment, "
You might as well ask what we would do if little green men from mars showed up at mass." I also liked Lad's idea of the super-soaker; the thought of sprinkling holy water on him had already occurred to me, but I didn't think of a good way to get close enough.

The comment "
and your priest seems to be to be allowing it" was part of my difficulty in picturing the scenario & what I'd do, because it's hard to imagine with some Trad priests. If the priest seemed to be allowing it, maybe I'd stay at least a while out of extreme curiosity as to why. And in the hope that 2Vermont's conjecture might be the case.
