Several hundred Catholic bishops from around the country have gathered in Baltimore for a national meeting at a time when many of us faithful are grieving, angry and running out of patience. The horrifying scale of the clergy sexual abuse crisis, as chronicled by a Pennsylvania grand jury report in August that revealed widespread abuse and cover-up over several decades, underscores an obvious but essential point: Bishops can’t be trusted to police themselves.

Moreover, a recent investigation by The Boston Globe and The Philadelphia Inquirer found that more than 130 bishops — nearly one-third of those still living — have been accused of failing to adequately respond to sexual abuse in their dioceses. New explosions are still coming. In August, a former assistant to Bishop Richard Malone of Buffalo released hundreds of secret documents that showed how the bishop continued to send predator priests back into parishes. Bishop Michael Bransfield of West Virginia resigned in September after claims that he had sexually harassed younger priests.

It’s not the first meeting of its kind: 16 years ago, after The Globe’s groundbreaking “Spotlight” investigation, bishops met in Dallas to adopt zero-tolerance policies. Any priest who had abused a minor would be removed. Civilian review boards would investigate claims of clergy misconduct. Those policies led to the removal of hundreds of priests, but the bishops didn’t implement procedures that held themselves to the same standard of accountability.

The Vatican, including Pope Francis, has also not done enough. A proposal to create a Vatican tribunal to evaluate accusations against bishops — an idea floated by the pope’s own Pontifical Commission for the Protection of Minors — has gone nowhere.
