For more than 50 years, the National Prayer Breakfast has been a Washington institution. Every president has attended the breakfast since Eisenhower. Besides the presidents ... the one constant presence at the National Prayer Breakfast has been Douglas Coe. Although he's not an ordained minister, the 79-year-old Coe is the most important religious leader you've never seen or heard. Scores of senators in both parties ... go to small weekly Senate prayer groups that Coe attends, [including] senators John McCain, Barack Obama and Hillary Clinton. Observers who have investigated Coes group, called The Fellowship Foundation, [describe] a secretive organization. Coe repeatedly urges a personal commitment to Jesus Christ. Its a commitment Coe compares to the blind devotion that Adolph Hitler demanded. Hitler, Goebbels and Himmler. Think of the immense power these three men had. Coe also quoted Jesus and said: One of the things [Jesus] said is 'If any man comes to me and does not hate his father, mother, brother, sister, his own life, he can't be a disciple." Writer Jeff Sharlet ... lived among Coe's followers six years ago, and came out troubled by their secrecy and rhetoric. We were being taught the leadership lessons of Hitler, Lenin and Mao. Hitler's genocide wasn't really an issue for them. It was the strength that he emulated, said Sharlet, who ... has now written about The Fellowship, also known to insiders as The Family, in [a] book called The Family: The Secret Fundamentalism at the Heart of American Power.
