The Roman Catholic Church is enjoying some of its best press in decades. But, says a new documentary by PBS' Frontline," "Secrets of the Vatican," the morally wrenching controversies that threatened to destroy the church's credibility, starting about the time Pope John Paul II died in 2005, have not fully subsided. "Secrets of the Vatican" ... takes an unsparing look at the state of the church Pope Francis inherited from his predecessor, Pope Benedict XVI. "2012 was an annus horribilis for [Benedict]," Antony Thomas, the ... director of the film [said]. A horrible year on many fronts, not just with mounting evidence of financial impropriety at the Vatican bank, but also with incidents of sexual abuse by clergy spreading to more than 20 countries and, further, exposure of church hypocrisy about homosexuality. At the same time, reports emerged from Rome of a "gay mafia" inside the church that included some of its top officials, who were unafraid to wield political power and at the same time live an openly promiscuous gay lifestyle. "There was a lot that came to light, including a man who was, as it were, providing choirboys as rent boys," Thomas said. "Secrets of the Vatican" also looks at the connection between the church's requirement that its clergy must remain celibate and the high number of sexual abuse incidents among its ranks. Thomas said the film's specificity about the nature of sexual abuses was necessary - because it's still an overwhelming concern.
