Wow! That's actually really cool. I have to confess that my initial reaction to your post was, "What the hell is Commonweal? Did he forget the th at the end?". And then it turns out that Commonweal is a magazine by and for catholic lay people. Which makes it odd that i've never heard of it, since I am A) Catholic and B) enjoy laying people.

ouch. ....Right. Sorry. So as I was saying, right before I began to solemnly swear that I would make my Confirmation next week for sure or next month at the very latest, was that I'd be really interested to see what a non-ecclesiastic catholic take on BtVS would be. Catholics (in my experience) don't really find the uproarious humor in dialogue like "Note to self: religion...freaky.", but on the other hand for a professed atheist Joss Whedon throws a lot of christian imagery (yes, BESIDES the crosses, thank you) and allusions at the viewer.
