This is not a joke. The founder was on (LA based) KROQ station's The Kevin and Bean Show to talk about his new church (in Oregon, official church status still pending) that will use the stories of superheroes, instead of passages from the Bible, to teach morals and life lessons.
You can check out their Facebook page here. On the morning show interview, they mentioned they're open to anyone joining. I'm not of a church going religion (and I don't really go to my equivalent anyway), but I have to be honest, this would probably get me to show up more oftne.
