17 As regards not merely the temporary aid given to the laboring classes, but the establishment of permanent institutions in their behalf, it is most commendable for charity to undertake them. It will thus see that more certain and more reliable means of assistance will be afforded to the necessitous. That kind of help is especially worthy of recognition which forms the minds of mechanics and laborers to thrift and foresight, so that in course of time they may be able, in part at least, to look out for themselves. To aim at that is not only to dignify the duty of the rich toward the poor, but to elevate the poor themselves, for, while it urges them to work in order to improve their condition, it preserves them meantime from danger, it refrains immoderation in their desires, and acts as a spur in the practice of virtue. Since, therefore, this is of such great avail and so much in keeping with the spirit of the times, it is a worthy object for the charity of righteous men to undertake with prudence and zeal.
