An in-depth study released by the Barna Group on behalf of the American Bible Society found that 50 percent of Americans believe the Bible, Quran and the Book of Mormon hold different expressions of the same truths. The survey also found that Americans' reliance on the Bible has decreased slightly in 2012 from 2011, although the Christian holy book retains an important place in people's lives.

The study, which was conducted in March and surveyed over 2,000 adults through phone and online interviews, found that 85 percent of American households own a Bible – although that number was down from 88 percent in 2011. Similarly, 48 percent agreed that the Bible has all the knowledge needed to live a meaningful life, while that number was 53 percent in 2011.
