The former vicar general of the Munich archdiocese did not respond to repeated attempts to contact him for comment at home. Phone calls to the archdiocese for reaction on Thursday night were not answered. On Wednesday, speaking generally about the question of Father Hullermann’s therapy, a spokesman at the archdiocese, Bernd Oostenryck, said, “Thirty years ago, the subject was treated very differently in society.”

“There was a tendency to say it could be therapeutically treated,” Mr. Oostenryck said.

Father Hullermann was transferred in December 1977 to the St. Andreas Church in Essen, an industrial city in the Ruhr region not far from where he was born in Gelsenkirchen. The three sets of parents who complained to the church said Father Hullermann had had “sexual relations” with their children in February 1979, according to a statement this week by the diocese in Essen.

In the minutes taken by the priest in charge of the parish at the meeting with the parents, he noted that in order to protect their children they “would not file charges under the current circumstances.”

For decades it was common practice in the church not to involve law enforcement in sexual abuse cases. Vowing to change that, Bavarian bishops called Thursday for strengthening the duty of church officials to report cases of abuse, and even urged a change in German law requiring them to do so.

Spared prosecution after his transgressions in Essen, which according to the statement released by the diocese he “did not dispute,” Father Hullermann instead was ordered to undergo therapy with Dr. Huth. The archdiocese said that order was personally approved by Archbishop Ratzinger.

Dr. Huth said he had recommended one-on-one sessions, which Father Hullermann refused. Instead the priest took part in group sessions, usually seated in a circle with eight other patients, who had a mix of disorders, including pedophilia. Dr. Huth, 80, said that Father Hullermann had problems with alcohol, for which he prescribed medication, but that he was “neither invested nor motivated” in his therapy.

“He did the therapy out of fear that he would lose his post” and a “fear of punishment,” Dr. Huth said.
