324. Led by the Spirit, the family circle is not only open to life by generating it within itself, but also by going forth and spreading life by caring for others and seeking their happiness. This openness finds particular expression in hospitality,(Familiaris Consortio 44) which the word of God eloquently encourages: “Do not neglect to show hospitality to strangers, for thereby some have entertained angels unawares” (Heb 13:2). When a family is welcoming and reaches out to others, especially the poor and the neglected, it is “a symbol, witness and participant in the Church’s motherhood”.(Familiaris Consortio 49) Social love, as a reflection of the Trinity, is what truly unifies the spiritual meaning of the family and its mission to others, for it makes present the kerygma in all its communal imperatives. The family lives its spirituality precisely by being at one and the same time a domestic church and a vital cell for transforming the world.(Compendium of the Social Doctrine of the Church, 248-254)
A pastor I know once worked this theme into many of his wedding homilies. One of the fruits of a sacramental marriage is an expanded sense of others. Sacramental love between two cannot help but spread to family, friends, and even the poor and needy. I can only pray for such grace. What about you?
