Greenfield: A new Barna Group poll has found that “Major Christian Leaders Are Widely Unknown, Even Among Christians.” In alarming fashion, the evangelical Group’s president, George Barna, interpreted the findings to mean “that Christianity is losing its grip on American culture” and concluded that one reason “is because even the highest-profile leaders of the faith community have limited resonance with the population.” Given the track record of its highest-profile leaders, there should be no question why the community cannot relate. But Barna doesn’t even stop to think that perhaps they’ve but their faith elsewhere, like in the movement itself.
