A short year and a half after the first hopeful buzz surrounded the National Association of Evangelical’s “revolutionary” new manifesto, “For the Health of the Nation: An Evangelical Call to Civic Responsibility,” which promised a shift in evangelical priorities from gay marriage and abortion to the environment and the poor, the revolution has petered out. The 30-million member NAE, citing an inability to reach consensus on global warming, has announced that it will take no stand on the issue. The NAE’s waffle comes a month after its president, Ted Haggard, received a letter from the bright stars of evangelicaldom — 20 evangelical leaders, including Chuck Colson, James Dobson and Richard Land — warning Haggard not to take any official position that would pit equally-Bible-believing evangelicals against one another over the “still debatable” existence and seriousness of global warming.
