Irishman to bishop or archbishop. John, promoted, William FitzJohn, bishop of Ossory to the bishopric of Cashel, while Alexander Bicknor, a personal recommendation of Edward, was given Dublin. In January 1318, John sent a congratulatory letter to Edward on his victory over Edward Bruce. He had passed an excommunication of all enemies of Edward and later singled out Robert and Edward Bruce. John had allowed Edward to keep the crusade tax imposed by the Council of Vienne, while reminding him that England was a papal fief and that he owed John an oath of loyalty. A few months later, John heard from Irish princes petitioning for the replacement of Edward as sovereign lord of Ireland, stating that successive kings of England had not respected the papal grant of Ireland to Henry II of England. John's letter to Edward inferred that a second papal evaluation of the lordship of Ireland was not out of the question. Canonization of Thomas Aquinas By November 1317, Guillelmo de Tocco, Prior of the Benevento Dominican monastery, was heading a preliminary investigation into Thomas Aquinas' sainthood. In the Summer of 1318, John met with de Tocco, who presented letters from the regal heads of Sicily imploring for a papal inquiry into the sainthood of Aquinas. De Tocco also presented John with notarized records of Aquinas' miracles and requests from princes and universities asking for Aquinas' canonization. John chose three cardinals, none of whom was a Dominican, to scrutinize the presented records. Finding no errors, they gave their recommendation to John. John then issued two letters nominating: Umberto, Archbishop of Naples, Angelo, Bishop of Viterbo, and Pandulpho de Sabbello, who was unable to attend, as papal commissioners. De Tocco gather two of the three papal commissioners in the Archbishop's palace in Naples. The inquiry lasted from 21 July to 18 September 1319. On the final day, the documentation of the inquiry was signed, sealed and sent to the Papal Curia at Avignon. Upon receiving the documents John turned them over to a cardinal committee. On 23 June 1321, John created a new commission consisting of Peter Ferri, Bishop of Agnani, Andrew, Bishop of Terracina, and Pandulpho de Sabbello. This inquiry lasted fifteen days, during which the commission heard the testimony of one hundred eleven witnesses. The commission sent finalized documents to the Papal Curia and John XXII canonized Thomas Aquinas formally on 18 July 1323. Conflict with
