In his apostolic exhortation Familiaris consortius, Pope St. John Paul II declared that the mission of the family is to:
In Amoris Laetitia, Pope Francis wrote “The sacrament of marriage is not a social convention, an empty ritual or merely the outward sign of a commitment. The sacrament is a gift given for the sanctification and salvation of the spouses, since their mutual belonging is a real representation, through the sacramental sign, of the same relationship between Christ and the Church. The married couple are therefore a permanent reminder for the Church of what took place on the cross; they are for one another and for their children witnesses of the salvation in which they share through the sacrament.”
And in the first Latin American Congress meeting, he stated: "The family reflects the image of God, in his deepest mystery, and in this way allows you to see human love as a sign of God's love and presence (Lumen Fidei, 52). In the family, faith is mixed with maternal milk. For example, the simple and spontaneous gesture to ask for a blessing that is conserved in many of our peoples, encapsulates the biblical conviction that God's blessing is passed on from father to son."
