If you want to know about God, you might want to talk to an atheist.

Heresy? Perhaps. But a survey that measured Americans’ knowledge of religion found that atheists and agnostics knew more, on average, than followers of most major faiths. In fact, the gaps in knowledge among some of the faithful may give new meaning to the term “blind faith.”

A majority of Protestants, for instance, couldn’t identify Martin Luther as the driving force behind the Protestant Reformation, according to the survey, released Tuesday by the Pew Forum on Religion & Public Life. Four in 10 Catholics misunderstood the meaning of their church’s central ritual, incorrectly saying that the bread and wine used in Holy Communion are intended to merely symbolize the body and blood of Christ, not actually become them.

Atheists and agnostics – those who believe there is no God or who aren’t sure – were more likely to answer the survey’s questions correctly. Jews and Mormons ranked just below them in the survey’s measurement of religious knowledge – so close as to be statistically tied.

So why would an atheist know more about religion than a Christian?
