53 Our thoughts turn also to Christian families. to ask them to remain faithful to their vital mission in society. May they consecrate themselves in this jubilee year to the Immaculate Heart of Mary! For married couples this act of piety will be a valuable aid in performing their conjugal duties of chastity and faithfulness. It will keep pure the atmosphere in which their children grow up. Even more, it will make the family, inspired by its devotion to Mary, a living center of social rebirth and apostolic influence.
