Castiel quoting scripture

[gwydia.livejournal.com]

Hi,

I'm looking for any stories where Castiel quotes scripture in response to something. I'd especially like it if he got into an argument with an over-zealous nutjob.
It would be even more awesome if it were part of a really plotty fic, but I'll take one-shots and shorter stories as well.

As for pairings - I'm not really picky, can be gen or not. I do generally prefer Destiel over Wincest....
