The Daily Beast reports further info on the gay orgy in the apartment of Monsignor Luigi Capozzi, secretary to Cardinal Francesco Coccopalmerio, who heads the Vatican Council for Legislative Texts. Nosy neighbors complained to the Swiss Guard about the noisy flocks of young men.
The article concludes by mentioning another papal aide and financial expert, Cardinal George Pell of Australia, who recently went home to face charges of sexual abuse alleged to have happened while he was a priest there years ago.
All this, and the many other examples of which we are sadly aware, suggest the "celibate priests" thing has had the effect of preselecting candidates for the priesthood who already knew they'd never marry a woman. The priesthood attracted pedophiles and gay men who had no interest in an adult heterosexual relationship and understood the priesthood gave them perfect cover by proscribing behavior they a priori found repellant.
Furthermore, the church has been aware of the problem for many decades. A former priest, long married to a former nun when I worked with him in the mid-1970s, reported a 'drill sergeant' priest at his seminary would angrily exhort the novices to "be manly." He inferred both the existence of the problem, and an institutional awareness thereof, some 5 decades ago that I know of.
