A gift from God in the beginning, renewed and elevated by Christ, marriage is the great sign of how God loves us, pointing toward the flourishing of all persons and societies.
Men and women were created with complete, but at the same time complementary, natures. In a very real way, men and women were made for each other in both nature and spirit. The necessity for love and unity is built into our nature as men and women, and it is intimately connected with the fruitfulness of family life. Indeed, as we shall see, the sacramental union towards which men and women are called is inseparable from the manifestation of that very love’s fruitfulness: children and the creation of society’s most basic unit, the family.
