There’s a difference between being self-righteous and being arrogant. I find evangelists much more self-righteous than arrogant. I always presumed churches turned people self-righteous somehow. Then it dawned on me that I had it all wrong, which adds to my arrogance since I must now be right.
Churches don’t cause people to be self-righteous; self-righteous people merely like being around other self-righteous people. Throughout history the church conveniently provided a gathering point for each age of self-righteous people. And there are a lot of them!
This helped me feel better about my churchy friends and family. Everyone needs friends, and since self-righteous people oppose other-unrighteous people, it gives them a place to be righteous together – apart from us.
