The lawsuit says the priest assaulted a woman last year while counseling her at a Roman Catholic shrine in Bucks County.
The woman volunteered at Our Lady of Czestochowa (CHEST’-uh-HOV’-uh) in Doylestown.
The Associated Press is not naming the accused priest because he could not be reached for comment.
He belongs to the Pauline Fathers, a religious order at the shrine. A woman who answered the phone Wednesday said the Pauline supervisors were “in prayer” and not available for comment.
The lawsuit also accuses Bucks County prosecutors and Philadelphia Archdiocese officials of failing to pursue the complaint and letting the priest flee.
Neither office immediately returned phone messages.
