Christian MMA is a bit of a religious subculture that pops up here and there, but it has made its way to the big screen with the new documentary Fight Church. The documentary, which is currently making the rounds at film festivals, follows a "fight club" that was started in a church and appears to feature several fights including one marketed as a "pastor versus paster" bout.
For a reasonably short trailer, there is plenty of craziness packed in. Aside from pastor v. pastor, we have men shooting guns while someone declares that "Mainstream Christianity has feminized men," the requisite declaration that "Jesus didn't tap," and a fairly young kid being told to be brave before going into what looks to be a fairly brutal full contact bout.
It's pretty wild stuff, and I'd be lying if I didn't want to see it out of a sort of morbid curiosity.
