Natural reason itself convinces us that such opinions about the ruling of a State are very widely removed from the truth. Nature herself bears witness that all power of whatever kind ultimately emanates from God, that greatest and most august fountain. Popular rule, however, which without any regard to God is said to be naturally in the multitude, though it may excellently avail to supply the fires of many blandishments and excitements of many forms of covetousness, yet rests on no probable reason, nor can have sufficient strength to ensure public security and the quiet permanence of order. Verily things under the auspices of these doctrines have come to such a pass that many sanction this as a law in civil jurisprudence, to wit, that sedition may rightly be raised. For the idea prevails that princes are really nothing but delegates to express the popular will; and so necessarily all things become alike, are changeable at the popular nod, and a certain fear of public disturbance is forever hanging over our heads.
But to think with regard to religion, that there is no difference between unlike and contrary forms, clearly will have this issue—an unwillingness to test any one form in theory and practice. And this, if indeed it differs from atheism in name, is in fact the same thing. Men who really believe in the existence of God, if they are to be consistent and not ridiculous, will, of necessity, understand that the different methods of divine worship involving dissimilarity and conflict, even on the most important points, cannot be all equally probable, equally good, and equally accepted by God. And thus that faculty of thinking whatever you like and expressing whatever you like to think in writing, without any thought of moderation, is not of its own nature, indeed, a good in which human society may rightly rejoice, but, on the contrary, a fount and origin of many ills.
Liberty, in so far as it is a virtue perfecting man, should be occupied with that which is true and that which is good; but the foundation of that which is true and that which is good cannot be changed at the pleasure of man, but remains ever the same, nor indeed is it less unchangeable than nature herself. If the mind assent to false opinions, if the will choose for itself evil, and apply itself thereto, neither attains its perfection, but both fall from their natural dignity, and both lapse by degrees into corruption. Whatever things, therefore, are contrary to virtue and truth, these things it is not right to place in the light before the eyes of men, far less to defend by the favor and tutelage of the laws. A well-spent life is the only path to that heaven whither we all direct our steps; and on this account the State departs from the law and custom of nature if it allows the license of opinions and of deeds to run riot to such a degree as to lead minds astray with impunity from the truth, and hearts from the practice of virtue.
But to exclude the Church which God Himself has constituted from the business of life, from the laws, from the teaching of youth, from domestic society, is a great and pernicious error. A well-regulated State cannot be when religion is taken away; more than needs be, perhaps, is now known of what sort of a thing is in itself, and whither tends that philosophy of life and morals which men call civil. The Church of Christ is the true teacher of virtue and guardian of morals; it is that which keeps principles in safety, from which duties are derived, and by proposing most efficacious reasons for an honest life, it bids us not only fly from wicked deeds, but rule the motions of the mind which are contrary to reason when it is not intended to reduce them to action. But to wish the Church in the discharge of its offices to be subject to the civil power is a great rashness, a great injustice. If this were done order would be disturbed, since things natural would thus be put before those which are above nature; the multitude of the good whose common life, if there be nothing to hinder it, the Church would make complete, either disappears or at all events is considerably diminished, and besides, a way is opened to enmities and conflicts—how great the evil which they bring upon each order of government the event has too frequently shown.
Such doctrines are not approved by human reason, and are of the greatest gravity as regards civil discipline, the Roman Pontiffs our predecessors—well understanding what the apostolic office required of them—by no means suffered to go forth without condemnation. Thus Gregory XVI., by Encyclical Letter, beginning Mirare vos, of August 15, 1832, inveighed with weighty words against those doctrines which were already being preached, namely, that in divine worship no choice should be made; and that it was right for individuals to judge of religion according to their personal preferences, that each man's conscience was to himself his sole sufficient guide, and that it was lawful to promulgate whatsoever each man might think, and so make a revolution in the State. Concerning the reasons for the separation of Church and State, the same Pontiff speaks thus: "Nor can we hope happier results either for religion or the government, from the wishes of those who are eagerly desirous that the Church should be separated from the State, and the mutual good understanding of the sovereign secular power and the sacerdotal authority be broken up. It is evident that these lovers of most shameless liberty dread that concord which has always been fortunate and wholesome, both for sacred and civil interests." To the like effect Pius IX., as opportunity offered, noted many false opinions which had begun to be of great strength, and afterward ordered them to be collected together in order that in so great a conflux of errors Catholics might have something which, without stumbling, they might follow.
From these decisions of the Popes it is clearly to be understood that the origin of public power is to be sought from God Himself and not from the multitude; that the free play for sedition is repugnant to reason; that it is a crime for private individuals and a crime for States to observe nowhere the duties of religion or to treat in the same way different kinds of religion; that the uncontrolled right of thinking and publicly proclaiming one's thoughts is not inherent in the rights of citizens, nor in any sense to be placed among those things which are worthy of favor or patronage. Similarly it ought to be understood that the Church is a society, no less than the State itself, perfect in kind and right, and that those who exercise sovereignty ought not to act so as to compel the Church to become subservient or inferior to themselves, or suffer her to be less free to transact her own affairs or detract aught from the other rights which have been conferred upon her by Jesus Christ. But in matters however in complex jurisdiction, it is in the highest degree in accordance with nature and also with the counsels of God—not that one power should secede from the other, still less come into conflict, but that that harmony and concord should be preserved which is most akin to the foundations of both societies.
These, then, are the things taught by the Catholic Church concerning
