Quote:"5. During Our Pontificate We too have frequently and with urgent insistence denounced the current trend to atheism which is alarmingly on the increase. In 1924 when Our relief-mission returned from the Soviet Union We condemned Communism in a special Allocution[3] which We addressed to the whole world. In our Encyclicals Miserentissimus Redemptor,[4] Quadragesimo Anno,[5] Caritate Christi,[6] Acerba Animi,[7] Dilectissima Nobis,[8] We raised a solemn protest against the persecutions unleashed in Russia, in Mexico and now in Spain. Our two Allocutions of last year, the first on the occasion of the opening of the International Catholic Press Exposition, and the second during Our audience to the Spanish refugees, along with Our message of last Christmas, have evoked a world-wide echo which is not yet spent. In fact, the most persistent enemies of the Church, who from Moscow are directing the struggle against Christian civilization, themselves bear witness, by their unceasing attacks in word and act, that even to this hour the Papacy has continued faithfully to protect the sanctuary of the Christian religion, and that it has called public attention to the perils of Communism more frequently and more effectively than any other public authority on earth.
6. To Our great satisfaction, Venerable Brethren, you have, by means of individual and even joint pastoral Letters, accurately transmitted and explained to the Faithful these admonitions. Yet despite Our frequent and paternal warning the peril only grows greater from day to day because of the pressure exerted by clever agitators. Therefore We believe it to be Our duty to raise Our voice once more, in a still more solemn missive, in accord with the tradition of this Apostolic See, the Teacher of Truth, and in accord with the desire of the whole Catholic world, which makes the appearance of such a document but natural. We trust that the echo of Our voice will reach every mind free from prejudice and every heart sincerely desirous of the good of mankind. We wish this the more because Our words are now receiving sorry confirmation from the spectacle of the bitter fruits of subversive ideas, which We foresaw and foretold, and which are in fact multiplying fearfully in the countries already stricken, or threatening every other country of the world.
7. Hence We wish to expose once more in a brief synthesis the principles of atheistic Communism as they are manifested chiefly in bolshevism. We wish also to indicate its method of action and to contrast with its false principles the clear doctrine of the Church, in order to inculcate anew and with greater insistence the means by which the Christian civilization, the true civitas humana, can be saved from the satanic scourge, and not merely saved, but better developed for the well-being of human society."
