The Poverty obliged by the Rule was taught and lived by Our Lord and His Apostles

7. Moreover since the rule itself expressly contains that the friars may appropriate nothing to themselves neither house nor place nor any thing, and [thus] has it been declared by the same predecessor, Pope Gregory IX, and by not a few others, that this ought to be observed not only individually but also in common, which so strict an abdication insensate cleverness has distorted with livid detractions, lest the clarity of the perfection of the same friars wound with unskillful sermons of such ones, We say that the abdication of this kind of property over all things not only individually but also in common is in the sight of God meritorious and holy, which Christ showing the way to perfection both taught by word and strengthened by example, and which the first founders of the Church militant, just as [streams which] had grown from the spring itself, in willing to live perfectly diverted along their own stream-beds of doctrine and life, nor did anyone think to withstand them because sometimes it is said that Christ had a purse; for so Christ Himself, whose works are perfect, in His acts walked the way of perfection, because sometimes condescending to the imperfections of the infirm yet He would [still] extol the way of perfection, and He would not damn the infirm paths of the imperfect; so Christ received the person of the infirm in [receiving] a purse, and thus assuming in not a few other things an weak human nature, just as is testified by the Evangelical narrative, He condescended to the infirm not only in the flesh but also in the mind, for He so assumed human nature that being perfect in His works [and] made humble according to our [state], He remained exalted in His own. And thus by the highest dignity of charity one, who does not turn away from the highest rectitude of perfection, is drawn to certain acts conformable to our imperfection. For thus did Christ act and teach the works of perfection, He acted even as one weak, just as is sometimes patent by [His] flight and [His] purse; but being perfectly perfect in both so that He might show Himself to perfect and imperfect as the way of salvation, that He had come to save both, and that in turn He willed to die for [the sake] of both.
