CCC 1639 The consent by which the spouses mutually give and receive one another is sealed by God himself.1 From their covenant arises “an institution, confirmed by the divine law,. .. even in the eyes of society.”2 The covenant between the spouses is integrated into God’s covenant with man: “Authentic married love is caught up into divine love.”3
