So-called moral permissiveness rests on an erroneous conception of human freedom; the necessary precondition for the development of true freedom is to let oneself be educated in the moral law. Those in charge of education can reasonably be expected to give young people instruction respectful of the truth, the qualities of the heart, and the moral and spiritual dignity of man.
"The Good News of Christ continually renews the life and culture of fallen man; it combats and removes the error and evil which flow from the ever-present attraction of sin. It never ceases to purify and elevate the morality of peoples. It takes the spiritual qualities and endowments of every age and nation, and with supernatural riches it causes them to blossom, as it were, from within; it fortifies, completes, and restores them in Christ." (2526-2527)
The fecundity of conjugal love cannot be reduced solely to the procreation of children, but must extend to their moral education and their spiritual formation. "
The role of parents in education is of such importance that it is almost impossible to provide an adequate substitute." The right and the duty of parents to educate their children are primordial and inalienable. (2221)
The forms taken by modesty vary from one culture to another. Everywhere, however modesty exists as an intuition of the spiritual dignity proper to man. It is born with the awakening consciousness of being a subject. Teaching modesty to children and adolescents means awakening in them respect for the human person. (2524)
In our own time, in a world often alien and even hostile to faith, believing families are of primary importance as centers of living, radiant faith. For this reason the Second Vatican Council, using an ancient expression, calls the family the Ecclesia Domestica. It is in the bosom of the family that parents are "by word and example...the first heralds of the faith with regard to their children. They should encourage them in the vocation which is proper to each child, fostering with special care any religious vocation."
It is here that the father of the family, the mother, children, and all members of the family exercise the priesthood of the baptized in a privileged way "by the reception of the sacraments, prayer and thanksgiving, the witness of a holy life, and self-denial and active charity." Thus the home is the first school of Christian life and "a school for human enrichment." Here one learns endurance and the joy of work, fraternal love, generous - even repeated forgiveness, and above all divine worship in prayer and the offering of one's life. (1656-1657)
