I don't think that could be further from the truth. I love the Simpsons, but have noticed how Homer often falls asleep in church. He has also referred to people going to church as "church jerks", and talked about them believing in their phony balogna God. Yes in that one episode Homer and Bart were Catholic, but their overall lifestyle and attitudes clearly shows they are hardly even Christian.
Also, this thread shows the "off-topic" board should be brought back.
