Aquinas had made a remarkable impression on all who knew him. He was placed on a level with the [[Apostle Paul]] and [[Augustine of Hippo|Augustine]], receiving the titles ''doctor angelicus'' (Angelic Doctor) and ''doctor communis'' (Common Doctor).
In 1319, the Roman Catholic Church began investigations preliminary to Aquinas's canonization; on [[July 18]], 1323, he was pronounced a [[saint]] by Pope John XXII at Avignon. At the [[Council of Trent]] only two books were placed on the Altar, the Bible and St. Thomas Aquinas's Summa
