Bonaventure, OFM (ˈbɒnəvɛntʃər,_ˌbɒnəˈvɛntʃər ; Bonaventura da Bagnoregio ˌbɔnavenˈtuːra da (b)baɲɲoˈrɛːdʒo; Bonaventura de Balneoregio; born Giovanni di Fidanza; 1221 – 15 July 1274) was an Italian Catholic Franciscan bishop, cardinal, scholastic theologian and philosopher.
The seventh Minister General of the Order of Friars Minor, he also served for a time as Bishop of Albano. He was canonised on 14 April 1482 by Pope Sixtus IV and declared a Doctor of the Church in 1588 by Pope Sixtus V. He is known as the "Seraphic Doctor" (Doctor Seraphicus). His feast day is 15 July. Many writings believed in the Middle Ages to be his are now collected under the name Pseudo-Bonaventure.
He was born at Civita di Bagnoregio, not far from Viterbo, then part of the Papal States. Almost nothing is known of his childhood, other than the names of his parents, Giovanni di Fidanza and Maria di Ritella. Bonaventure reports that in his youth he was saved from an untimely death by the prayers of Francis of Assisi, which is the primary motivation for Bonaventure's writing the vita.
He entered the Franciscan Order in 1243 and studied at the University of Paris, possibly under Alexander of Hales, and certainly under Alexander's successor, John of Rochelle. In 1253 he held the Franciscan chair at Paris. A dispute between seculars and mendicants delayed his reception as Master until 1257, where his degree was taken in company with Thomas Aquinas. Three years earlier his fame had earned him the position of lecturer on The Four Books of Sentences—a book of theology written by Peter Lombard in the twelfth century—and in 1255 he received the degree of master, the medieval equivalent of doctor.
After having successfully defended his order against the reproaches of the anti-mendicant party, he was elected Minister General of the Franciscan Order. On 24 November 1265, he was selected for the post of Archbishop of York; however, he was never consecrated and resigned the appointment in October 1266.
