Pope Francis issued a letter to Catholics around the world on Monday condemning the crime of priestly sexual abuse and its cover-up and demanding accountability, in response to new revelations in the United States of decades of misconduct by the Catholic Church. Francis begged forgiveness for the pain suffered by victims and said lay Catholics must be involved in any effort to root out abuse and cover-up. He blasted the clerical culture that has been blamed for the crisis, with church leaders more concerned for their reputation than the safety of children. (AP)
