23 In these many and so great miseries, you well know, venerable brethren, that no small alleviation is to be found in the institutes of St. Francis, if only they are brought back to their pristine state; for if they only were in a flourishing condition, faith and piety, and every Christian virtue would easily flourish; the lawless desire for perishing things would be broken; nor would men refuse to have their desires ruled by virtue, though that seems to many to be a most hateful burthen. Men bound together by the bonds of true fraternal concord would mutually love each other, and would give that reverence which is becoming to the poor and distressed, as bearing the image of Christ. Besides, those who are thoroughly imbued with the Christian religion feel a conviction that those who are in legitimate authority are to be obeyed for conscience' sake, and that in nothing is anyone to be injured.
