BRUSSELS  The Roman Catholic Church, battered by sexual abuse scandals from the United States to Belgium, is facing a new set of damaging allegations in the Netherlands. Figures released Thursday by an investigative commission showed that almost 2,000 people had made complaints of sexual or physical abuse against the church, in a country with only four million Catholics.

“The Roman Catholic Church has not faced a crisis like this since the French Revolution,” Peter Nissen, a professor of the history of religion at Radboud University in the Netherlands, said of the growing abuse scandal.

With one legal case starting this week, and accusations against two former bishops, the reaction of the church appears to have fueled the crisis. Nearly all of the cases are decades old, with probably no more than 10 from the past 20 years.

Asked in March on television about the hundreds of complaints already surfacing, one of the church’s most senior figures, Cardinal Adrianus Simonis, shocked the nation by replying not in Dutch but in German. “Wir haben es nicht gewusst”  We knew nothing  he said, using a phrase associated with Nazi excuses after World War II.
