Author and pollster George Barna is alarmed by the trends he's seeing. In fact, he asserts that the United States is standing at "the precipice of self-annihilation." There's only one way to avoid a tragic demise, Mr. Barna believes, and that is to "recover the values that made this nation great and that must be firmly in place for order, reason, and unity to prevail." He clearly states, however, that this book doesnt́ aim to convert anyone to his religious views; indeed, he insists it is crucial for Christians to work with non-Christians. From analyzing more than 30,000 interviews with U.S. adults, Barna has determined that Americans, while belonging to more than 200 different religious affiliations, belong to just seven faith tribes: Casual Christians (67 percent); Captive Christians (16 percent); Jews (2 percent); Mormons (1.5 percent); Pantheists, mostly Eastern religions (1.5 percent); Muslims (less than 1 percent); and Skeptics, including Atheists and Agnostics (11 percent). Barna profiles each groupś religious beliefs, political perspectives, and self-conceptions. A chapter on the media is especially provocative, since Barna considers media exposure Americaś most widespread and serious addiction. Barna believes that if the seven faith tribes assert themselves and promote their shared values, the United States can reverse the recent decades of "cultural chaos and disintegration."
