speaking of those who do not fully understand their own religion...

I wonder if it was a Catholic boy who, when I was in 3rd or 4th grade, told me: "It's a sin to eat meat on Friday!".

It kinda worried me..until I finally asked someone... who said it WASN'T... which was one of my very early experiences of wondering how several different 'truths' could all be right. I think I was in high school before I finally began to how it all worked.
