25 For these reasons it has been long and specially Our desire that everyone should, to the utmost of his power, aim at imitating St. Francis of Assisi; therefore, as hitherto We have always bestowed special care upon the Third Order of St. Francis, so now, being called by the supreme mercy of God to the office of Sovereign Pontiff since thereby We can most opportunely do the same, We exhort Christian men not to refuse to enroll themselves in this sacred army of Jesus Christ. Many are those who everywhere of both sexes have already begun to walk in the footsteps of the Seraphic Father with courage and alacrity, whose zeal We praise and specially commend, so that, Venerable Brethren, We desire that by your endeavours especially it may be increased and extended to many. And the special point which We commend is that those who have adopted the insignia of Penance shall look to the image of its most holy founder, and strive to imitate him, without which the good that they would expect would be futile. Therefore take pains that the people may become acquainted with the Third Order and truly esteem it; provide that those who have the cure of souls sedulously teach what it is, how easily anyone may enter it, with how great privileges tending to salvation it abounds, what advantages, public and private, it promises; and in so doing all the more pains are to be taken because the Franciscans of the First and Second Order, having been struck recently with a heavy blow, are in a most piteous condition. God grant that they, defended by the patronage of their Father, may emerge, youthful and flourishing, from so many disasters; may he also grant that Christian people may rend towards the discipline of the Third Order with the same alacrity and the same numbers as formerly from all parts they threw themselves into the arms of St. Francis himself with a holy emulation.
