Breviaire Romain," Paris, 1893, p. 142 sqq.) The principles concerning preaching as laid down by St. Francis in c. ix of his Rule contain the secret of the great Franciscan preachers who have always been among the most successful and popular. Finally, chap. xii on missions amongst the infidels is a happy innovation in religious rules, as Angelo Clareno in his exposition wisely observed. There can be no doubt that the great impulse given to foreign missions in the thirteenth century is due to St. Francis, who was himself a missionary in the East and saw some of his brethren martyred for the Faith. Interpretation The ideal that St. Francis laid down in his rule is very high; the apostolical life was to be put in practice by his brethren, and indeed we see that St. Francis and his companions lived perfectly according to that standard. But the number of the friars rapidly increasing, and on the other hand, some being received into the order who had not the pure intentions and the great zeal of Francis, the rule gave rise to many controversies, and, as a consequence, to many declarations and expositions. The first exposition of the rule was given by St. Francis himself in his Testament (1226). He puts there his own and his first disciples' life as an example to the brothers. Moreover he forbids them "to ask for any letter from the Roman Curia, either for a church or for any other place, whether under pretext of preaching, or on account of their bodily persecution." He enjoins also on all brothers "not to put glosses on the Rule," but as he had written it purely and simply, so ought they "understand it simply and purely — and with holy operation observe it until the end." Nevertheless we have a great number of expositions of the rule, and it cannot be said that they are, in their greatest part, against the will of St. Francis. He himself had in his lifetime been humble enough to submit in everything to the decisions of the Church, and so he desired his sons to do. Even the Spirituals, who cleaved to the letter of the rule, as Olivi and Clareno, were not against reasonable expounding of the rule, and have written expositions thereof themselves. Besides, the decisions of the popes are not dispensations, but authentic interpretations of a rule, that
