14 Then the home of the Christian family, like that of Nazareth, will become an earthly abode of sanctity, and, so to speak, a sacred temple, where the Holy Rosary will not only be the particular prayer which every day rises to heaven in an odor of sweetness, but will also form the most efficacious school of Christian discipline and Christian virtue. This meditation on the Divine Mysteries of the Redemption will teach the adults to live, admiring daily the shining examples of Jesus and Mary, and to draw from these examples comfort in adversity, striving towards those heavenly treasures "where neither thief draws near, nor moth destroys" ( Luke 12, 33). This meditation will bring to the knowledge of the little ones the main truths of the Christian Faith, making love for the Redeemer blossom almost spontaneously in their innocent hearts, while, seeing, their parents kneeling before the majesty of God, they will learn from their very early years how great before the throne of God is the value of prayers said in common.
