Bonaventura, the two mendicant orders, and the Greeks at the council of Lyons (1274)

Abstract

For centuries it has been believed that at the famous council of Lyons, held in 1274 to reunite the Latin and Greek churches, the leading role defending Latin theological views in the debates that presumably took place was played by the great Franciscan theologian, Bonaventura. Recently, however, this view has been seriously called into question, and a re-evaluation of his role and that of other leading protagonists would seem to be in order. Far from being the ‘soul of the union,’ and the man who ‘crushed the Greeks in theological debate,’ as has been generally believed, Bonaventura’s part in the union seems to have been very limited. It is the purpose of this paper not only to put in clearer light and in its true context the work of Bonaventura with regard to the Greeks at the council, but also to indicate, if only rather briefly, the parts taken by other mendicants, the Franciscans John Parastron and Jerome of Ascoli, and the Dominicans, Albertus Magnus, William of Moerbeke, and their minister general, Peter of Tarentaise. Our aim, then, is to ascertain the relative importance of their respective roles in the preparations for, and the proclamation of, religious union.
