My friend Kris Barberg just sent me a fascinating little link. A Christian filmmaker friend of hers out in LA just made a short film called "The McPassion".
It's a bit out there. In fact, it's probably controversial. But it's a spot-on commentary about how much marketing is creeping into the church. You should watch it, for sure, but I think Rik Swartzwelder makes some really great observations on the "discussion" page. You should really go there and read what he has to say. It's excellent fodder for conversation.
I can't link directly to the discussion page, so go to themcpassion.com ...watch the movie...then read the discussion page. Good stuff.
