Peter John Olivi, in his native French Pierre Jean Olivi and also Pierre Déjean, (1248 - March 14, 1298) was a Franciscan theologian who, although he died professing the faith of the Roman Catholic Church, became a controversial figure in the arguments surrounding poverty at the beginning of the fourteenth century. In large part, this was due to his view that the Franciscan vow of poverty also entailed usus pauper (i.e., 'poor' or 'restricted' use of goods); while contemporary Franciscans generally agreed that usus pauper was important to the Franciscan way of life, they disagreed that it was part of their vow of poverty. His support of the extreme view of ecclesiastical poverty played a part in the ideology of the groups coming to be known as the Spiritual Franciscans or Fraticelli.
A Franciscan and theological author, born at Sérignan, Diocese of Béziers, 1248-9. At twelve he entered the Friars Minor at Béziers, and later took the baccalaureate at Paris. Returning to his native province, he soon distinguished himself by his strict observance of the rule and his theological knowledge.
Olivi cleverly defended himself in several responses (1283-85), and finally the General Chapter of Montpellier (1287) decided in his favour. The new general superior, Matthew of Aquasparta, sent him as lector in theology to the convent of Santa Croce in Florence, whence Matthew's successor, Raymond Gaufredi, sent him as lector to Montpellier. At the General Chapter of Paris in 1292 Olivi again gave explanations, which were apparently satisfactory. He spent his last years in the convent of Narbonne and died, surrounded by his friends, after an earnest profession of his Catholic Faith (published by Wadding ad a. 1297, n. 33) on 14 March, 1298.
Peace was not obtained by his death. His friends, friars and seculars, showed an exaggerated veneration for their leader, and honoured his tomb as that of a saint; on the other hand the General Chapter of Lyon in 1299 ordered his writings to be collected and burnt as heretical.
Father Ehrle considers (Archiv, III, 440) that Olivi was not the impious heretic he is painted in some writings of the Middle Ages, and states (ibid., 448) that the denunciation of his theological doctrine was rather a tactical measure of the adversaries of the severe principles of poverty and reform professed by Olivi. For the rest, Olivi follows in many points the doctrine of St. Bonaventure.
The numerous but for the most part unedited works of Olivi are appropriately divided by Ehrle into three classes:
