Leo XIII, 1878-1903

in the power and judgment of the Church; but other matters, which the civil and political order embraces, are rightly subject to civil authority, since Jesus Christ has ordered: "The things that are Caesar's, render to Caesar; the things that are God's to God" [cf. Matt. 22:21]. But occasions sometimes arise, when another method of concord is also efficacious for peace and liberty, namely, if rulers of public affairs and the Roman Pontiff agree on the same decision in some special matter. On these occasions the Church gives outstanding proof of her motherly devotion, when, as is her wont she shows all possible affability and indulgence. . . .

By this deed order is disturbed, because the things that are of nature are put over those that are above nature; the frequency of the blessings with which the Church would fill everyday life, if she were not hampered by anything, is destroyed or certainly greatly diminished; and besides a way is prepared for enmities and contentions; and, what great destruction they bring to both powers, the issue of events has demonstrated beyond measure. Such doctrines, which are not approved by human reason and are of great importance for civil discipline, the Roman Pontiffs, Our predecessors, since they understood well what the Apostolic office demanded of them, did by no means allow to pass uncondemned. Thus, Gregory XVI by the encyclical letter beginning, "Mirari vos," on the fifteenth day of August, 1832 [see note 1613 ff.], with great seriousness of purpose struck at those teachings which even then were being preached, that in divine worship no preference should be shown; that individuals are free to form their judgments about religion as they prefer; that one's conscience alone is his guide; and furthermore that it is lawful for everyone to publish what he thinks, and likewise to stir up revolution within the state. On questions of the separation of Church and state the same Pontiff writes thus: "We could not predict happier results both for religion and for the civil government from the wishes of those who desire that the Church be separated from the state, and that the mutual concord between the civil and ecclesiastical authorities be broken off. For, it is manifest that devotees of unhampered freedom fear that concord which has always been beneficial and salutary for both sacred and civil interests."—In a not dissimilar manner Pius IX, as opportunity presented itself, noted many of the false opinions which began to prevail, and afterwards ordered the same to be gathered together so that in, as it were, so great a sea of error, Catholics might have something to follow without mishap.¹
