The nation's Roman Catholic bishops won Vatican approval yesterday for their revised sex abuse policy, requiring every diocese to bar priests who molest children from working in the church.

Vatican authorization makes the plan church law for the United States and, therefore, binding on Catholic officials. Bishops have acknowledged that allowing dioceses to set their own rules often left molesters in parishes and helped create this year's many scandals.

The Holy See's announcement came three days after Pope John Paul II accepted the resignation of Cardinal Bernard Law as archbishop of Boston, removing a central figure from the abuse crisis that rocked the archdiocese 11 months ago.

"A number of bishops have added to the impact of this scandal by being, too often, negligent in our vigilance," Bishop Wilton Gregory, president of the U.S. Conference of Catholic Bishops, said yesterday. "We turn to the Catholic people for their help in making this a moment of new creation."

Making his first public appearance since resigning as archbishop, Law offered another apology yesterday and asked for forgiveness for his role in the clergy sex abuse scandal.

"As I said last Friday, it is my hope and it's my prayer that my resignation as archbishop might help the Archdiocese of Boston to experience healing, to experience reconciliation and to experience unity," Law told reporters at a news conference. He left without taking any questions.

Law, 71, said new policies and programs have been put in place in the past 11 months that he hoped would prevent future abuses by priests. Although he had hoped to remain head of the fourth-largest U.S. archdiocese, he said, "It came to be ever more clear to me that the most effective way I might serve the church at this moment was to resign."

The new policy approved by the Vatican attempts to balance the rights of victims and accused clergy in a discipline process separate from civil proceedings.

Bishops have pledged to report all allegations involving children to law enforcement in their communities, even though the church leaders are compelled to obey local civil law only on reporting abuse.

Under the new plan, bishops will conduct a confidential, preliminary inquiry when a molestation claim is made to determine whether it is plausible. If it is, the Vatican will be notified and will likely return the case to the bishop. The accused priest is to be put on leave and then must go before a clerical tribunal to determine his guilt or innocence.

The bishops dealt with the burgeoning crisis in June by approving a policy that would have allowed church leaders to pull priests out of their jobs as soon as they were accused. But Vatican officials expressed concern that the approach denied priests due process, and a joint U.S.-Vatican commission revised the plan.

U.S. bishops accepted the changes at their national meeting Nov. 13 and awaited the Holy See's final approval.

Guilty clerics will be barred from public ministry - saying Mass, teaching in Catholic schools, wearing a Roman collar - after a single case of abuse with a minor. Some might also be forced to leave the priesthood.

The Vatican released a letter to Gregory from Cardinal Giovanni Battista Re informing him of the Holy See's approval. "It appears necessary to devote every available resource to restoring the public image of the Catholic priesthood," it stated.

The crisis erupted in January when court documents released over the objection of the Boston Archdiocese revealed that Law had let predatory priests continue to serve after allegations surfaced against them.

Re, who heads the Congregation of Bishops, asked the U.S. bishops to continue their meetings with the heads of religious orders who have expressed concern about applying the policy to their members. A third of the nation's 46,000 priests are in religious orders such as the Jesuits and Franciscans.

The policy comes up for review in two years.

The bishops must face the complex task of implementing the plan, which takes effect March 1. Bishop William Lori of Bridgeport, Conn., a member of the panel that revised the policy, said the bishops plan to create a training program for clergy assigned to the tribunals, which will consist of three to five priests.

At least 325 U.S. priests have been removed from duty or resigned this year because of molestation claims. Lori said it was unclear how many will go before the church courts.

Under the new policy, bishops can ask the Vatican to waive the church's statute of limitations, which requires victims to come forward by age 28. Review boards including lay people will monitor how dioceses respond to abuse, but their work will be confidential and the policy stresses that only bishops can manage clergy.

David Clohessy, national director of the Survivors Network of Those Abused by Priests, said he felt the plan left too much discretion to bishops and did not allow enough oversight by lay people.

"We believe this policy is deeply flawed and even if it weren't, no words on paper alone can radically change these deeply ingrained behavior patterns," Clohessy said.

Sex abuse scandals have erupted in a number of other countries, including Ireland, Argentina and the pope's native Poland. Germany's Roman Catholic Church has also declared a national policy, after previously leaving it up to each diocese to deal with priests accused of molestation.
