People of faith may "know God"…but knowing about God– that's a different story. The Pew Research Center quizzed Americans on their knowledge of religion. And listen to this: the highest scorers were not the devout believers... They were actually Atheists and Agnostics! The people who have rejected religion outright or aren't exactly sure. Mormons and Jews came a close second, outperforming Protestants and Roman Catholics when it came to knowing details about all religions. It was even more shocking to see that people claiming a religion couldn't even answer simple questions about their own faith!

For example, more than half of Protestants couldn't even identify Martin Luther as the man who led the establishment of the Protestant church. The quiz was 32 questions long... The average number of correct answers: 16. That’s half. Seems like a lot of wrong answers for a nation where just about four in five people says they belong to some sort of religious group.

World renowned spiritual leaders Deepak Chopra, Marianne Williamson and Reverend Art Cribbs of the San Marino United Church of Christ spoke with CNN’s Kyra Phillips.
