22 Italy, however, owes more to Francis than any other nation whatever; which, as it was the principal theatre of his virtues, so also most received his benefits; and, indeed, at a time when many were bent on multiplying the sufferings of mankind, he was always offering the right hand of help to the afflicted and the cast down; he, rich in the greatest poverty, never desisted from relieving others' wants, neglectful of his own. In his mouth his native tongue, new-born, sweetly uttered its infant cries; he expressed the power of charity and of poetry with it in his canticles composed for the common people, and which have proved not unworthy of the admiration of a learned posterity. We owe to the mind of Francis that a certain breath and inspiration nobler than human has stirred up the minds of our countrymen so that, in reproducing his deeds in painting, poetry and sculpture, emulation has stirred the industry of the greatest artists. Dante even found in Francis matter for his grand and most sweet verse; Cimabue and Giotto drew from his history subjects which they immortalised with the pencil of a Parrhasius; celebrated architects found in him the motive for their magnificent structures, whether at the tomb of the Poor Man himself, or at the Church of St. Mary of the Angels, the witness of so many and so great miracles. And to these temples men from all parts are wont to come in throngs in veneration for the father of Assisi of the poor, to whom, as he had utterly despoiled himself of all human things, so the gifts of the divine bounty largely and copiously flowed. Hence it is clear that from this one man a host of benefits has flowed into the Christian and civil republic. But since that spirit of his, thoroughly and surpassingly Christian, is wonderfully fitted for all times and places, no one can doubt that the Franciscan institutions would be specially beneficial in this our age. And especially for this reason, that the tone and temper of our times seem for many reasons to be similar to those; for as in the 12th century divine charity had grown cold, so also is it now; nor is the neglect of Christian duties small, whether from ignorance or negligence; and, with the same bent and like desires, many consume their days in hunting for the conveniences of life, and greedily following after pleasures. Overflowing with luxury, they waste their own, and covet the substance of others; extolling indeed the name of human fraternity, they nevertheless speak more fraternally than they act; for they are carried away by self love, and the genuine charity towards the poorer and the helpless is daily diminished. In the time We are speaking of, the manifold errors of the Albigenses, by stirring up the masses against the power of the Church, had disturbed society and paved the way to a certain kind of Socialism . And in Our day, likewise, the favourers and propagators of Materialism have increased, who obstinately deny that submission to the Church is due, and hence proceeding gradually beyond all bounds, do not even spare the civil power; they approve of violence and sedition among the people, they attempt agrarian outbreaks, they flatter the desires of the proletariat, and they weaken the foundations of domestic and public order.
