ENCYCLICAL OF POPE PIUS XI
ON ATHEISTIC COMMUNISM
TO THE PATRIARCHS, PRIMATES,
ARCHBISHOPS, BISHOPS, AND OTHER ORDINARIES
IN PEACE AND COMMUNION WITH THE APOSTOLIC SEE.
Venerable Brethren, Health and Apostolic Benediction.
The promise of a Redeemer brightens the first page of the history of mankind, and the confident hope aroused by this promise softened the keen regret for a paradise which had been lost. It was this hope that accompanied the human race on its weary journey, until in the fullness of time the expected Savior came to begin a new universal civilization, the Christian civilization, far superior even to that which up to this time had been laboriously achieved by certain more privileged nations.
2. Nevertheless, the struggle between good and evil remained in the world as a sad legacy of the original fall. Nor has the ancient tempter ever ceased to deceive mankind with false promises. It is on this account that one convulsion following upon another has marked the passage of the centuries, down to the revolution of our own days. This modern revolution, it may be said, has actually broken out or threatens everywhere, and it exceeds in amplitude and violence anything yet experienced in the preceding persecutions launched against the Church. Entire peoples find themselves in danger of falling back into a barbarism worse than that which oppressed the greater part of the world at the coming of the Redeemer.
3. This all too imminent danger, Venerable Brethren, as you have already surmised, is bolshevistic and atheistic Communism, which aims at upsetting the social order and at undermining the very foundations of Christian civilization .
4. In the face of such a threat, the Catholic Church could not and does not remain silent. This Apostolic See, above all, has not refrained from raising its voice, for it knows that its proper and social mission is to defend truth, justice and all those eternal values which Communism ignores or attacks. Ever since the days when groups of “intellectuals” were formed in an arrogant attempt to free civilization from the bonds of morality and religion, Our Predecessors overtly and explicitly drew the attention of the world to the consequences of the dechristianization of human society. With reference to Communism, Our Venerable Predecessor, Pius IX, of holy memory, as early as 1846 pronounced a solemn condemnation, which he confirmed in the words of the Syllabus directed against “that infamous doctrine of so-called Communism which is absolutely contrary to the natural law itself, and if once adopted would utterly destroy the rights, property and possessions of all men, and even society itself.” Later on, another of Our predecessors, the immortal Leo XIII, in his Encyclical Quod Apostolici Muneris, defined Communism as “the fatal plague which insinuates itself into the very marrow of human society only to bring about its ruin.” With clear intuition he pointed out that the atheistic movements existing among the masses of the Machine Age had their origin in that school of philosophy which for centuries had sought to divorce science from the life of the Faith and of the Church.
