Canonization

By the 1300s, however, Thomas's theology had begun its rise to prestige. In the Divine Comedy (completed c. 1321), Dante sees the glorified soul of Thomas in the Heaven of the Sun with the other great exemplars of religious wisdom. Dante asserts that Thomas died by poisoning, on the order of Charles of Anjou; Villani cites this belief, and the Anonimo Fiorentino describes the crime and its motive. But the historian Ludovico Antonio Muratori reproduces the account made by one of Thomas's friends, and this version of the story gives no hint of foul play.

When the devil's advocate at his canonization process objected that there were no miracles, one of the cardinals answered, " Tot miraculis, quot articulis "—"there are as many miracles (in his life) as articles (in his Summa)". Fifty years after Thomas's death, on 18 July 1323, Pope John XXII, seated in Avignon, pronounced Thomas a saint.

A monastery at Naples, near Naples Cathedral, shows a cell in which he supposedly lived. His remains were translated from Fossanova to the Church of the Jacobins in Toulouse on 28 January 1369. Between 1789 and 1974, they were held in the Basilica of Saint-Sernin. In 1974, they were returned to the Church of the Jacobins, where they have remained ever since.

When he was canonized, his feast day was inserted in the General Roman Calendar for celebration on 7 March, the day of his death. Since this date commonly falls within Lent, the 1969 revision of the calendar moved his memorial to 28 January, the date of the translation of his relics to Church of the Jacobins, Toulouse.

Thomas Aquinas is honored with a feast day in some churches of the Anglican Communion with a Lesser Festival on 28 January.

The Catholic Church honours Thomas Aquinas as a saint and regards him as the model teacher for those studying for the priesthood. In modern times, under papal directives, the study of his works was long used as a core of the required program of study for those seeking ordination as priests or deacons, as well as for those in religious formation and for other students of the sacred disciplines (philosophy, Catholic theology, church history, liturgy, and canon law).
