CONDEMNING CURRENT ERRORS
Encyclical of Pope Pius IX promulgated on December 8, 1864.
On Naturalism and Socialism
DsZ 2890 (4.) And, since where religion has been removed from civil society, and the doctrine and authority of divine revelation repudiated, the genuine notion itself of justice and human right is darkened and lost, and the place of true justice and legitimate right is supplied by material force, thence it appears why it is that some, utterly neglecting and disregarding the surest principles of sound reason, dare to proclaim that "the people's will, manifested by what is called public opinion or in some other way, constitutes a supreme law, free from all divine and human control; and that in the political order accomplished facts, from the very circumstance that they are accomplished, have the force of right." But who, does not see and clearly perceive that human society, when set loose from the bonds of religion and true justice, can have, in truth, no other end than the purpose of obtaining and amassing wealth, and that (society under such circumstances) follows no other law in its actions, except the unchastened desire of ministering to its own pleasure and interests?
DsZ 2891 (4) Moreover, not content with removing religion from public society, they wish to banish it also from private families. For, teaching and professing the most fatal error of "Communism and Socialism," they assert that "domestic society or the family derives the whole principle of its existence from the civil law alone; and, consequently, that on civil law alone depend all rights of parents over their children, and especially that of providing for education."
DsZ 2892 (4) By which impious opinions and machinations these most deceitful men chiefly aim at this result, viz., that the salutary teaching and influence of the Catholic Church may be entirely banished from the instruction and education of youth, and that the tender and flexible minds of young men may be infected and depraved by every most pernicious error and vice.
On the independence of the Church from the Civil State
DsZ 2893 (5. Others meanwhile, reviving the wicked and so often condemned inventions of innovators, dare with signal impudence to subject to the will of the civil authority the supreme authority of the Church and of this Apostolic See given to her by Christ Himself, and to deny all those rights of the same Church and See which concern matters of the external order.
DsZ 2894 (5) For they are not ashamed of affirming "that the Church's laws do not bind in conscience unless when they are promulgated by the civil power; that acts and decrees of the Roman Pontiffs, referring to religion and the Church, need the civil power's sanction and approbation, or at least its consent; that the Apostolic Constitutions,6 whereby secret societies are condemned (whether an oath of secrecy be or be not required in such societies), and whereby their frequenters and favourers are smitten with anathema -- have no force in those regions of the world wherein associations of the kind are tolerated by the civil government......
DsZ 2895 (5) Nor do they blush openly and publicly to profess the maxim and principle of heretics from which arise so many perverse opinions and errors. For they repeat that the "ecclesiastical power is not by divine right distinct from, and independent of, the civil power, and that such distinction and independence cannot be preserved without the civil power's essential rights being assailed and usurped by the Church." Nor can we pass over in silence the audacity of those who, not enduring sound doctrine, contend that "without sin and without any sacrifice of the Catholic profession assent and obedience may be refused to those judgments and decrees of the Apostolic See, whose object is declared to concern the Church's general good and her rights and discipline, so only it does not touch the dogmata of faith and morals."
DsZ 2896 (6) Therefore, by our Apostolic authority, we reprobate, proscribe, and condemn all the singular and evil opinions and doctrines severally mentioned in this letter, and will and command that they be thoroughly held by all children of the Catholic Church as reprobated, proscribed and condemned.
