Cardinal Cupich Lies in Public, Calls Amoris Laetitia "Revolutionary"
Contrast with this Great Catholic Pope`s teaching on the subject .
13. In the next place, in order that the union of hearts between their chief Pastor and the whole Catholic flock may daily be strengthened, We here call upon you, venerable brothers, with particular earnestness, and strongly urge you to kindle, with priestly zeal and pastoral care, the fire of the love of religion among the faithful entrusted to you, that their attachment to this chair of truth and justice may become closer and firmer, that they may welcome all its teachings with thorough assent of mind and will, wholly rejecting such opinion, even when most widely received, as they know to be contrary to the Church's doctrine. In this matter, the Roman Pontiffs, Our predecessors, and the last of all, Pius IX, of sacred memory, especially in the General Council of the Vatican, have not neglected, so often as there was need, to condemn widespreading errors and to smite them with the apostolic condemnation. This they did, keeping before their eyes the words of St. Paul: "Beware lest any man cheat you by philosophy and vain deceit, according to the tradition of men, according to the elements of the world and not according to Christ."(7) All such censures, We, following in the steps of Our predecessors, do confirm and renew from this apostolic seat of truth, whilst We earnestly ask of the Father of lights(8) that all the faithful, brought to thorough agreement in the like feeling and the same belief, may think and speak even as Ourselves. It is your duty, venerable brothers, sedulously to strive that the seed of heavenly doctrine be sown broadcast in the field of God, and that the teachings of the Catholic faith may be implanted early in the souls of the faithful, may strike deep root in them, and be kept free from the ruinous blight of error. The more the enemies of religion exert themselves to offer the uninformed, especially the young, such instruction as darkens the mind and corrupts morals, the more actively should we endeavor that not only a suitable and solid method of education may flourish but above all that this education be wholly in harmony with the Catholic faith in its literature and system of training, and chiefly in philosophy, upon which the direction of other sciences in great measure depends.(9) Philosophy seeks not the overthrow of divine revelation, but delights rather to prepare its way, and defend it against assailants, both by example and in written works, as the great Augustine and the Angelic Doctor, with all other teachers of Christian wisdom, have proved to Us.
14. Now, the training of youth most conducive to the defense of true faith and religion and to the preservation of morality must find its beginning from an early stage within the circle of home life; and this family Christian training sadly undermined in these our times, cannot possibly be restored to its due dignity, save by those laws under which it was established in the Church by her Divine Founder Himself. Our Lord Jesus Christ, by raising to the dignity of a sacrament the contract of matrimony, in which He would have His own union with the Church typified, not only made the marriage tie more holy, but, in addition, provided efficacious sources of aid for parents and children alike, so that, by the discharge of their duties one to another, they might with greater ease attain to happiness both in time and in eternity. But when impious laws, setting at naught the sanctity of this great sacrament, put it on the same footing of mere civil contracts, the lamentable result followed, that, outraging the dignity of Christian matrimony, citizens made use of legalized concubinage in place of marriage; husband and wife neglected their bounden duty to each other; children refused obedience and reverence to their parents; the bonds of domestic love were loosened; and alas! the worst scandal and of all the most ruinous to public morality, very frequently an unholy passion opened the door to disastrous and fatal separations. These most unhappy and painful consequences, venerable brothers, cannot fail to arouse your zeal and move you constantly and earnestly to warn the faithful committed to your charge to listen with docility to your teaching regarding the holiness of Christian marriage, and to obey laws by which the Church controls the duties of married people and of their offspring.(10)
15. Then, indeed, will that most desirable result come about, that the character and conduct of individuals also will be reformed; for, just as from a rotten stock are produced healthless branches or worthless fruits, so do the ravages of a pestilence which ruins the household spread wide their cruel infection to the hurt and injury of individual citizens. On the other hand, when domestic society is fashioned in the mould of Christian life, each member will gradually grow accustomed to the love of religion and piety, to the abhorrence of false and harmful teaching, to the persuit of virtue, to obedience to elders, and to the restraint of the insatiable seeking after self interest alone, which so spoils and weakens the character of men. To this end it will certainly help not a little to encourage and promote those pious associations which have been established, in our own times especially, with so great profit to the cause of the Catholic religion.
