10 Our unshaken hope in this complete victory of God and of the Church receives daily confirmation (such is the infinite mercy of God!) from the noble ardor of innumerable souls whom we see turning themselves to God, in every country and in all classes of society. For most certainly a very powerful afflatus of the Holy Spirit is rushing through all lands, and is moving the hearts, especially the hearts of the young, to mount upwards to the highest summits of the Christian law, and, raising them above the vain observance of men, makes them ready to undertake even the most arduous deeds. This divine afflatus, We say, stirs the souls of all, even those who were unwilling, filling them with an intimate solicitude, and gives the yearning for God even to those who do not dare to acknowledge it. In like manner Our invitation to laymen, calling them to join the hosts of Catholic Action in order that they might become partakers in the apostolate of the hierarchy, has been accepted by the multitudes of the docile and the magnanimous in all lands; and the number of those who are striving with all their strength to defend the Christian law and to bring the whole life of the commonwealth into harmony with it, is daily growing both in the cities and in the country; and these men strive likewise to confirm the principles they preach, by the example of a blameless life. But when We behold so much impiety, so much trampling under foot of the most holy institutions, such great destruction of immortal souls, and lastly such great contempt of the Divine Majesty, We cannot refrain, Venerable Brethren, from pouring out the most bitter sorrow by which We are oppressed, and from lifting up Our voice with all the strength of the apostolic heart, in defense of the outraged rights of God, and of the holy desires of the human soul in its absolute need of God; and We do this the more readily because these hostile hosts, raging with diabolical spirit, are not content with declamation, but are striving with all their strength to give effect to their nefarious plans as speedily as possible. Woe to the race of men if God, being treated with such contempt by the natures He has made, should leave an open course to these floods of devastation, and should use them as scourges to punish the world withal!
