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.
