By November 1317, Guillelmo de Tocco, Prior of the Benevento Dominican monastery, was heading a preliminary investigation into [[Thomas Aquinas]]' sainthood.{{sfn|Gerulaitis|1967|p=36}} 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.{{sfn|Gerulaitis|1967|p=36}} De Tocco also presented John with notarized records of Aquinas's miracles and requests from princes and universities asking for Aquinas's canonization.{{sfn|Gerulaitis|1967|p=36}} John chose three cardinals, none of whom was a Dominican, to scrutinize the presented records.{{sfn|Gerulaitis|1967|p=37}} Finding no errors, they gave their recommendation to John.{{sfn|Gerulaitis|1967|p=37}} John then issued two letters, nominating as papal commissioners: Umberto, Archbishop of Naples; Angelo, Bishop of Viterbo; and Pandulpho de Sabbello, who was unable to attend.{{sfn|Gerulaitis|1967|p=37}}

De Tocco gathered two of the three papal commissioners in the Archbishop's palace in Naples{{sfn|Gerulaitis|1967|p=37}} and the inquiry lasted from 21 July to 18 September 1319.{{sfn|Gerulaitis|1967|p=37}} On the final day, the documentation of the inquiry was signed, sealed and sent to the Papal Curia at Avignon.{{sfn|Gerulaitis|1967|p=39}} Upon receiving the documents, John turned them over to a cardinal committee.{{sfn|Gerulaitis|1967|p=39}} On 23 June 1321, John created a new commission consisting of Peter Ferri, Bishop of Agnani, Andrew, Bishop of Terracina, and Pandulpho de Sabbello.{{sfn|Gerulaitis|1967|p=39}} This inquiry lasted fifteen days, during which the commission heard the testimony of 111 witnesses.{{sfn|Gerulaitis|1967|p=39}} The commission sent finalized documents to the Papal Curia and John XXII canonized Thomas Aquinas formally on 18 July 1323.{{sfn|Gerulaitis|1967|pp=40–41}}
