Inscrutabili Dei Consilio §6

⁶ Furthermore, that kind of civilization which conflicts with the doctrines and laws of holy Church is nothing but a worthless imitation and meaningless name. Of this those peoples on whom the Gospel light has never shown afford ample proof, since in their mode of life a shadowy semblance only of civilization is discoverable, while its true and solid blessings have never been possessed. Undoubtedly, that cannot by any means be accounted the perfection of civilized life which sets all legitimate authority boldly at defiance; nor can that be regarded as liberty which, shamefully and by the vilest means, spreading false principles, and freely indulging the sensual gratification of lustful desires, claims impunity for all crime and misdemeanor, and thwarts the goodly influence of the worthiest citizens of whatsoever class. Delusive, perverse, and misleading as are these principles, they cannot possibly have any inherent power to perfect the human race and fill it with blessing, for "sin maketh nations miserable."(3) Such principles, as a matter of course, must hurry nations, corrupted in mind and heart, into every kind of infamy, weaken all right order, and thus, sooner or later, bring the standing and peace of the State to the very brink of ruin.
