From America:
Mark Twain said that history does not repeat itself, but it rhymes. The sexual abuse scandal that continues to echo throughout the church in America, as evidenced by the recent controversy over the decision to allow Cardinal Bernard Law to preside at one of the memorial Masses for Pope John Paul II in Rome after his death on April 2, bears a striking resemblance to a series of crises that roiled the church in the Middle Ages, particularly in the 11th century. Then, as now, the higher clergy seemed to be completely unaware of the damage that scandalous sexual behavior was causing to both the victims and the community as a whole.
Problems in the 11th century were much more widespread than in our own. Priests and bishops were unaccountable to secular law, and abusive behavior extended beyond children to include adults. Many had concubines, or live-in prostitutes, who were completely at the mercy of their clerical patrons. Some bishops used their authority over the clergy to compel priests into acts of sodomy, as well.
