Pope Francis has created a church tribunal to judge bishops who fail to protect children from sexually abusive priests, the Vatican announced Wednesday, a move long sought by abuse victims and their advocates. The new court will be part of the powerful Congregation for the Doctrine of the Faith, the Catholic Church's chief watchdog. Since 2001, the congregation has judged priests accused of sexual abuse, but there has been no Vatican office with a similar role to judge bishops. The Rev. Federico Lombardi, a Vatican spokesman, said the Pope will appoint a secretary and permanent staff for the tribunal. Longtime critics of the Vatican called Wednesday's move a sea change" within the Catholic Church. "Priests abuse children, and so do bishops," said Terence McKiernan, president of the watchdog group BishopAccountability.org. "Bishops who offend are inevitable enablers, and the commission's plan must confront that sad fact." Advocates for sexual abuse victims gave the new tribunal qualified approval. "Time will tell whether these moves actually result in holding bishops accountable for cover-ups of crimes," Boston-based church reform group Voice of the Faithful said. "But these steps are the most promising the Vatican has yet taken." The new court was advocated by Boston Cardinal Sean O'Malley, who has long pushed the Vatican to discipline bishops who failed to protect children.
