“Americans are both deeply religious and profoundly ignorant about religion,” Stephen Prothero noted in his book, “Religious Literacy.” “Atheists may be as rare in America as Jesus-loving politicians are in Europe, but here faith is almost entirely devoid of content. One of the most religious countries on earth is also a nation of religious illiterates.”

Nearly two-thirds of Americans say they believe that the Bible holds the answer to all or most of life’s basic questions. Yet only one-third know that Jesus delivered the Sermon on the Mount, and 10 percent think that Joan of Arc was Noah’s wife.
