 In fact, when the Archbishop of Vercelli appeared and explained the whole matter to the Pope, Bishop Oberto disappeared, and a diligent search was unable to locate him.Pope Innocent then took counsel with his advisors, and Oberto was judged unworthy of the ministry of the altar ("ministerio altaris indignum").Then the Pope wrote a letter to Bisho-elect Sessa, ordering him and the Archbishop of Vercelli to use the powers granted to them when they were named Apostolic Visitors to depose Bishop Oberto.
