10 Finally, following the invariable custom of the Church in times of difficulty, let all the faithful, under your direction, unceasingly pray and beseech God to look down on France that His mercy may overcome his wrath. The unbridled license of speech and of the press, has many times outraged the Majesty of God; men are not wanting who not only ungratefully repudiate the benefits of Jesus Christ, the Saviour of the world, but even go so far in their impiety as to glory in not believing in the existence of God. To Catholics will fall the duty of making reparation by a great spirit of faith and piety for these perverse aberrations of mind and deed, and of publicly proving that they have nothing more at heart than the glory of God, nothing dearer than the religion of their forefathers. Those especially, whose life is passed in more intimate union with God in the cloister, should excite themselves to more and more generous charity, and strive to appease the Lord by their humble prayers, voluntary self denials, and offering of self. And thus, with the help of the Divine Mercy, we are confident that the strayed will come to repentance, and the name of France will regain its ancient greatness.
