I remember at school we had a missionary who told us about some parish in a country where people didn't wear clothes as a rule.

Some members of the congregation started dressing up to go to church, and everyone was looking at them instead of joining in the Mass. So the priest announced that in future would people make a point of not wearing clothes when they came to Mass, because it was distracting people from paying attention to the service and to their prayers.

I always liked that story. It shows a right sense of what matters and what doesn't, and a respect for cultural diversity.
