Top Vatican officials - including the future Pope Benedict XVI - did not defrock a priest who molested as many as 200 deaf boys, even though several American bishops repeatedly warned them that failure to act on the matter could embarrass the church, according to church files newly unearthed as part of a lawsuit. The internal correspondence from bishops in Wisconsin directly to Cardinal Joseph Ratzinger, the future pope, shows that while church officials tussled over whether the priest should be dismissed, their highest priority was protecting the church from scandal. The documents emerge as Pope Benedict is facing other accusations that he and direct subordinates often did not alert civilian authorities or discipline priests involved in sexual abuse when he served as an archbishop in Germany and as the Vatican's chief doctrinal enforcer. The Wisconsin case involved an American priest, the Rev. Lawrence C. Murphy, who worked at a renowned school for deaf children from 1950 to 1974. But it is only one of thousands of cases forwarded over decades by bishops to the Vatican office called the Congregation for the Doctrine of the Faith, led from 1981 to 2005 by Cardinal Ratzinger.
