I was really surprised by this survey, lot of pre-conceived notions I had about religious people are completely off-base:
For example, it's not evangelicals or Catholics who did best - it's atheists and agnostics.
It's not Bible-belt Southerners who scored highest - they came at the bottom.
Those who believe the Bible is the literal word of God did slightly worse than average, while those who say it is not the word of God scored slightly better.
Barely half of all Catholics know that when they take communion, the bread and wine literally become the body and blood of Christ, according to Catholic doctrine.
I was surprised about the bible belt southerners scoring lowest and Catholics not knowing the meaning behind communion. How can you not know the meaning, even I've been to enough Catholic church services to know why you're getting a snack.
