1 To the great Jubilee which was celebrated in Rome and is now extended to the whole world for the period of this year, which served to purify souls and called so many to a more perfect way of life, is now to be added, as a fulfillment of the fruits received or expected from the Holy Year, the solemn commemoration which Catholics everywhere are preparing to celebrate, the Seventh Centenary of the blessed passage of St. Francis of Assisi from his exile on earth to his heavenly home. Since Our immediate Predecessor has assigned this Saint, who was sent by Divine Providence for the reformation not only of the turbulent age in which he lived but of Christian society of all times, as the patron of "Catholic Action," it is only right that Our children who labor in this field according to Our commands should in union with the numerous Franciscan brotherhood call to mind and praise the works, the virtues, and the spirit of the Seraphic Patriarch. While doing this, they must reject that purely imaginary figure of the Saint conjured up by the defenders of modern error or by the followers of luxury and worldly comforts, and seek to bring Christians to the faithful imitation of the ideal of sanctity which he exemplified in himself and which he learned from the purity and simplicity of the doctrines of the Gospels.
