Quod Apostolici Muneris (on Socialism)
Pope Leo XIII, December 28, 1878
"Surely these are they who, as the sacred Scriptures testify, "Defile the flesh, despise dominion and blaspheme majesty." They leave nothing untouched or whole which by both human and divine laws has been wisely decreed for the health and beauty of life. They refuse obedience to the higher powers, to whom, according to the admonition of the Apostle, every soul ought to be subject, and who derive the right of governing from God; and they proclaim the absolute equality of all men in rights and duties. They debase the natural union of man and woman, which is held sacred even among barbarous peoples; and its bond, by which the family is chiefly held together, they weaken, or even deliver up to lust.
Lured, in fine, by the greed of present goods, which is "the root of all evils which some coveting have erred from the faith,"they assail the right of property sanctioned by natural law; and by a scheme of horrible wickedness, while they seem desirous of caring for the needs and satisfying the desires of all men, they strive to seize and hold in common whatever has been acquired either by title of lawful inheritance, or by labor of brain and hands, or by thrift in one's mode of life. These are the startling theories they utter in their meetings, set forth in their pamphlets, and scatter abroad in a cloud of journals and tracts. Wherefore, the revered majesty and power of kings has won such fierce hatred from their seditious people that disloyal traitors, impatient of all restraint, have more than once within a short period raised their arms in impious attempt against the lives of their own sovereigns.
But the boldness of these bad men, which day by day more and more threatens civil society with destruction, and strikes the souls of all with anxiety and fear, finds its cause and origin in those poisonous doctrines which, spread abroad in former times among the people, like evil seed bore in due time such fatal fruit. For you know, venerable brethren, that that most deadly war which from the sixteenth century down has been waged by innovators against the Catholic faith, and which has grown in intensity up to today, had for its object to subvert all revelation, and overthrow the supernatural order, that thus the way might be opened for the discoveries, or rather the hallucinations, of reason alone. This kind of error, which falsely usurps to itself the name of reason, as it lures and whets the natural appetite that is in man of excelling, and gives loose rein to unlawful desires of every kind, has easily penetrated not only the minds of a great multitude of men but to a wide extent civil society, also. Hence, by a new species of impiety, unheard of even among the heathen nations, states have been constituted without any count at all of God or of the order established by him; it has been given out that public authority neither derives its principles, nor its majesty, nor its power of governing from God, but rather from the multitude, which, thinking itself absolved from all divine sanction, bows only to such laws as it shall have made at its own will.
The supernatural truths of faith having been assailed and cast out as though hostile to reason, the very Author and Redeemer of the human race has been slowly and little by little banished from the universities, the Lyceums and gymnasia—in a word, from every public institution. In fine, the rewards and punishments of a future and eternal life having been handed over to oblivion, the ardent desire of happiness has been limited to the bounds of the present. Such doctrines as these having been scattered far and wide, so great a license of thought and action having sprung up on all sides, it is no matter for surprise that men of the lowest class, weary of their wretched home or workshop, are eager to attack the homes and fortunes of the rich; it is no matter for surprise that already there exists no sense of security either in public or private life, and that the human race should have advanced to the very verge of final dissolution."
