Georgetown professor assesses how well candidates 'thump the Bible'" - Catholic News Service, 2/15/08:

the candidates who are getting the highest marks from Berlinerblau for using -- but not overusing -- the Bible in their campaigns are Democratic Sens. Barack Obama of Illinois and Hillary Clinton of New York.

"their forays into the Bible did not endanger their campaigns by generating scads of negative publicity," something the author says former Democratic candidates Sen. John Kerry of Massachusetts [...] did.

Less successful in his religious references was former New York Mayor Rudy Giuliani [...] not surprising that Giuliani, a Catholic, did not often cite Scripture in his talks because Catholics in general "are not given to paroxysms of scriptural citation."

"Very few of my good Catholic friends are perfect Catholics," Berlinerblau said in an interview with Catholic News Service.

"Not only the American experience but 2,000 years of biblical interpretation have demonstrated that no empire, no society and rarely even one denomination has ever been able to agree on what the Bible says," Berlinerblau said.
