§ 1. On Liberty of Worships

444. Note beforehand. That liberty or equality of worships lies greatly in ambush against the Catholic faith, nothing is more evident than this. For through it there is brought into Catholic kingdoms that horrible system, most repugnant even to the natural light of reason itself, "of the indifference of any religion whatsoever, which, after every distinction of truth and error has been taken away, boldly asserts that men can attain eternal salvation in the worship of any religion whatsoever," and thus it casts peoples down into the abyss of incredulity (Pius IX, Enc., November 9, 1846).

445. PRINCIPLES. I. Liberty of worships, considered as doctrine, is a false principle of liberalism, which a Catholic legislator ought to impede by all the ways in which he can. Reason: he who cannot favor lesser vices, how much more ought he to resist those things which tear out the foundations of the commonwealth (St. Alph., de Prohib. lib., c. 1, n. 4; opusc. Fedelta dei vassalli).

Liberalism is a politico-religious system which professes an independence of the State from the Church so complete that the State rules itself, no respect being had to Religion, as if this did not exist, and all religions were in reality equal in themselves.

Moreover, the Supreme Pontiffs have always reprobated this liberty and equality of worships: "What more insane can be devised?" exclaims Pius VI in the Letter to Cardinal La Rochefoucauld (on March 10, 1791). Gregory XVI, in the Encyclical Mirari vos; Pius IX, in the Encyclical Quanta cura (December 8, 1864) and in the Syllabus (propositions 77, 78, and 79); Leo XIII, in the Encyclical Libertas (June 20, 1888), condemned this system by their supreme authority. The same Pontiff spoke thus concerning this doctrine in the Encyclical Immortale Dei: "If it differs from Atheism in name, in reality it differs not at all."

Note. But what kind of sin against faith he commits who professes liberalism was said above at n. 441.

II. Liberty of worships and of conscience can sometimes be tolerated where the prince cannot impede it without graver detriment to the true religion and commonwealth. Thus the Angelic Doctor teaches (2.2, q. 10, a. 11): Human rule is derived from divine rule, and ought to imitate it. But God, although he is omnipotent and supremely good, nevertheless permits some evils to be done in the universe which he could prohibit, lest, by their being removed, greater goods be taken away, or even worse evils follow. St. Alphonsus is plainly consonant with the Angelic Doctor (II, 18). Cf. Zigliara, Summa Phil., p. 247.

III. Liberty of worships, existing in fact, creates a twofold danger for the faithful, both of embracing the theoretical error concerning the equal value of religions, and of confusing political tolerance with dogmatic tolerance (Villada, Casus Consc., I, p. 59).

The matter is clear. From this twofold danger it must always be discerned whether someone in reality has fallen into a sin opposed to faith, or has only undergone the danger of falling into it, and whether the matter is one of doctrinal liberalism, or only of political parties.

446. From these things you will resolve: A. As regards liberalism, as it is doctrine:

In order to determine what sin against faith he commits who professes this liberalism, one must carefully inspect (as Genicot says) what he understands by the sentence to which he gives assent, since among those who have not completely turned aside to atheism or rationalism and who wish to remain Catholics, this word liberalism is taken with manifold variety; then one must see how far, by reason of ignorance and good faith, each one is excused from formal sin.

Hence: 1. He is a heretic who: a) fully embraces the doctrine of liberalism, that is, the full independence of the State from the Church, or (what is worse) the subjection of the Church to the authority of the State. For some subordination of the State to the Church is manifestly contained in the full power with which Christ furnished Peter and his successors; b) the same must be said of those liberals who pertinaciously hold certain particular doctrines which are also adverse to divine faith, for example, that by force of a merely civil contract there is given among Christians a true marriage. Cf. Sarda y Salvani, Le liberalisme est un peche.

2. They are excused from heresy, but expose themselves to danger, who defend these errors on account of ignorance for the most part culpable, and yet do not bear the mind of retaining them when they shall have known them to be reprobated by the Church. Likewise, by defect of religious assent, they sin gravely against prudence or reverence owed to the Church who hold only some secondary error, but one by no means contrary to divine faith, for example the 76th proposition of the Syllabus, concerning progress going to follow for the Church from the abrogation of the civil empire. But here some good faith can easily be admitted.

B. As regards liberalism, as it denotes political parties.

Before all things one must examine whether those who adhere to such parties nevertheless otherwise seem to fulfill the offices of good Catholics. Then it must prudently be explored whether they themselves admit something evil in doctrine or manner of acting, or without sufficient reason cooperate in the evil counsels of others; and according to these things let them be judged.

Concerning cooperation of this kind a question often occurs when there is question of schools, assemblies, and other social works.
