In 1264 a new Master General of the Order of Preachers was elected, John of Vercelli. It was taken as an opportunity to engage in some academic politics, since Humbertus de Romans, Peter's patron, was dead. One hundred and eight of Peter's statements in his Commentary on the Sentences of Peter Lombard were denounced as heretical.B. Smeraldo, Intorno all'opuscolo IX di san Tommaso d'Aquino. Pietro da Tarantasia ha errato in teologia? (Roma 1945). But, though Peter withdrew from his professorship, John of Vercelli appointed Thomas Aquinas to write a defense of the 108 propositions.Responsio ad fr.

Peter's reputation was such that he was immediately elected Provincial of the French Province for a three-year term (1264-1267). He was granted his release from office at the General Chapter, which was held in Bologna in May, 1267.Benedictus Maria Reichert, Acta Capitulorum Generalium Ordinis Praedicatorum Vol. I (Rome-Stuttgart 1898), p. 139. Potthast, no. 20022. At the conclusion of his term, and after Thomas of Aquinas' rejoinder to his critics was circulated, Peter returned to his Chair at the University of Paris (1267). In 1269 he was reelected to the office of Provincial of the French Province, and he held the post until he was named Archbishop of Lyons.Paolo Vian, "Innocenzo V, beato."
