Actually it's impressive there aren't more of them. You know, I used to think this was unacceptably stupid. Then it occurred to me that we do do a lot of really, really stupid stuff. What do we call stupid? Is it a risk taken that we would not take for fun? (Or, in this case, 'communion'?) Or maybe I'm tired or just getting old.
Thank goodness Leon Festinger had the short Seekers UFO cult available as an example for cognitive dissonace rather than a mouthful like Full Gospel Tabernacle in Jesus Name.
