BONAVENTURA (Giovanni di Fidanza, called Doctor Seraphicus): Theologian; b. at Bagnorea (50 m. n.n.w. of Rome) 1221; d. at Lyons July 15, 1274. He entered the order of St. Francis probably in 1238; went to Paris, 1242 or 1243, and studied under Alexander of Hales; lectured there on the "Sentences" of Peter Lombard and on the Holy Scriptures till the university suspended lectures in 1255; was chosen general of his order, 1257; cardinal bishop of Albano, 1273. His last public act was an impressive speech delivered before the Council of Lyons in May, 1274, for the union of the Eastern and Western churches. He was canonized by Sixtus IV in 1482. In defense of his order, before he became its general, during the contest between the Sorbonne and the mendicant monks, he wrote his De paupertate Christi, in reply to William of St. Amour's De periculis novissimorum temporum (1256); by a somewhat forced and sophistical argumentation he represents voluntary poverty as an element of moral perfection. Of his general views on monastic life he has given an exposition in his Determinationes quœstionum circa regulam Francisci. In his administration he was mild yet firm. As a teacher and author he occupies one of the most prominent places in the history of medieval theology; not so much, however, on account of any strongly pronounced originality as on account of the comprehensiveness of his views, the ease and clearness of his reasoning, and a style in which still linger some traces of the great charm of his personality. His mystical and devotional writings–as, far instance, De septem itineribus œternitatis–are almost imitations of Hugo of St. Victor. His dialectical writings are more independent. His Breviloquium (ed. Da Vicenza, 2d ed., Freiburg, 1881) is one of the best expositions of Christian dogmatics produced during the Middle Ages.
