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. They bear witness to this responsibility first by creating a home where tenderness, forgiveness, respect, fidelity, and disinterested service are the rule. The home is well suited for the education in the virtues .
Parents have the grave responsibility to give good example to their children.
He who disciplines his son will profit by him. Fathers, do not provoke your children to anger, but bring them up in the discipline and instruction of the Lord. This already happens when family members help one another to grow in faith by the witness of a Christian life in keeping with the Gospel. Family catechesis precedes, accompanies, and enriches other forms of instruction in the faith. Parents have the mission of teaching their children to pray and to discover their vocation as children of God.
