This encyclical, written as a means of coutering the errors of liberalism, begins by saying thus: "by institutions and by the example of teachers, the minds of the youth are corrupted and a tremendous blow is dealt to religion and the perversion of morals is spread. So the restraints of religion are thrown off, by which alone kingdoms stand. We see the destruction of public order, the fall of principalities, and the overturning of all legitimate power approaching". This is so eerily close to our modern times, and the errors addressed therein are all too familiar in a society built upon them.
Best quotes:
-"To use the words of the fathers of Trent, it is certain that the Church “was instructed by Jesus Christ and His Apostles and that all truth was daily taught it by the inspiration of the Holy Spirit.” Therefore, it is obviously absurd and injurious to propose a certain “restoration and regeneration” for her as though necessary for her safety and growth, as if she could be considered subject to defect or obscuration or other misfortune."
-"The people therefore must be zealously taught that a marriage rightly entered upon cannot be dissolved; for those joined in matrimony God has ordained a perpetual companionship for life and a knot of necessity which cannot be loosed except by death...marriages will have an unhappy end which are entered upon contrary to the discipline of the Church or without God’s favor or because of concupiscence alone, with no thought of the sacrament and of the mysteries signified by it."
-"This perverse opinion [indifferentism] is spread on all sides by the fraud of the wicked who claim that it is possible to obtain the eternal salvation of the soul by the profession of any kind of religion, as long as morality is maintained."
-"Here We must include that harmful and never sufficiently denounced freedom to publish any writings whatever and disseminate them to the people, which some dare to demand and promote with so great a clamor. We are horrified to see what monstrous doctrines and prodigious errors are disseminated far and wide in countless books, pamphlets, and other writings...Is there any sane man who would say poison ought to be distributed, sold publicly, stored, and even drunk because some antidote is available"
