(RNS) Pop quiz: Who said “We often suffer, but we are never crushed. Even when we don’t know what to do, we never give up”?

According to a recent poll, more Americans attributed the passage to comic book hero Captain America, the Rev. Martin Luther King Jr. and former President George W. Bush than its actual source: the New Testament book of 2 Corinthians.

A survey commissioned by the American Bible Society found that 56 percent of Americans surveyed misattributed the quote. At 27 percent, King received the most misplaced credit; just 12 percent correctly attributed it to the Bible.

The survey by Harris Interactive was conducted online among 2,572 adults.
