Is the Gannon mentioned in Jeff Sharlet's article in Harper's the same Gannon? The article in question is "Jesus Plus Nothing", referring to the D.C. prayer group house, Ivanwald.
EXCERPT:
Bengt began it. He was one of the house's leaders, a twenty-four-year-old North Carolinian with sad eyes and spiky eyebrows and a loud, disarming laugh that made him sound like a donkey. From inside the house, waiting for a phone call, he opened a second-floor window and called to Gannon for a ball. Gannon, the son of a Texas oilman, worked as a Senate aide<3>; he had blond hair and a chin like a plow, and he sang in a choir. He tossed one up, which Bengt caught and dispatched toward the basket. “Nice,” Gannon drawled as the ball sank through.
...
“It's okay if you bump into the other guys, too,” Gannon told me as my turn approached. “The idea's kinda to get that tension building.” Ahead of me Beau bent his knees to take another shot. The moment the ball rolled off his fingers, Wayne, also from Georgia, jumped up and hurled his own ball over Beau's head. As he returned to earth, his elbow descended on Beau's shoulder like a hammer. “Bump that,” he said.
Bump was designed to bring out your hostilities. The Family believes that you can't grow in Jesus unless you “face your anger,” and then abandon it. When bump worked right, each man was supposed to lose himself, forgetting even the precepts of the game. Sometimes you wanted to get the ball in, sometimes you wanted to knock it out. In, out, it didn't matter. Your ball, his, who cared? Bump wasn't horseplay, it was a physicalized theology. It was to basketball what the New Testament is to the Old: stripped down to one simple story that always ends the same. Bump, Jesus. Bump, Jesus.
FOOTNOTE:
3. Gannon worked for Senator Don Nickles, then the second-ranking Republican. The man who oversaw Ivanwald and interviewed us for admission was a lawyer named Steve South, who formerly had been Senator Nickles's chief counsel and was still a close associate.
