“The intimate community of life and love which constitutes the married state has been established by the Creator and endowed by him with its own proper laws…. God himself is the author of marriage.”
The vocation to marriage is written in the very nature of man and woman as they came from the hand of the Creator. Marriage is not a purely human institution despite the many variations it may have undergone through the centuries in different cultures, social structures, and spiritual attitudes. These differences should not cause us to forget its common and permanent characteristics. Although the dignity of this institution is not transparent everywhere with the same clarity, some sense of the greatness of the matrimonial union exists in all cultures. “The well-being of the individual person and of both human and Christian society is closely bound up with the healthy state of conjugal and family life.”
God who created man out of love also calls him to love the fundamental and innate vocation of every human being. For man is created in the image and likeness of God who is himself love.
Since God created him man and woman, their mutual love becomes an image of the absolute and unfailing love with which God loves man. It is good, very good, in the Creator’s eyes. And this love which God blesses is intended to be fruitful and to be realized in the common work of watching over creation: “And God blessed them, and God said to them: ‘Be fruitful and multiply, and fill the earth and subdue it.'”
Holy Scripture affirms that man and woman were created for one another: “It is not good that the man should be alone.” The woman, “flesh of his flesh,” i.e., his counterpart, his equal, his nearest in all things, is given to him by God as a “helpmate”; she thus represents God from whom comes our help. “Therefore a man leaves his father and his mother and cleaves to his wife, and they become one flesh.”
Marriage is based on the consent of the contracting parties, that is, on their will to give themselves, each to the other, mutually and definitively, in order to live a covenant of faithful and fruitful love. If consent is lacking there is no marriage. The consent consists in a “human act by which the partners mutually give themselves to each other”: “I take you to be my wife” – “I take you to be my husband.” This consent that binds the spouses to each other finds its fulfillment in the two “becoming one flesh.” The consent must be an act of the will of each of the contracting parties, free of coercion or grave external fear.
“By reason of their state in life and of their order, [Christian spouses] have their own special gifts in the People of God.” This grace proper to the sacrament of Matrimony is intended to perfect the couple’s love and to strengthen their indissoluble unity. By this grace they “help one another to attain holiness in their married life and in welcoming and educating their children.” Christ is the source of this grace. “Just as of old God encountered his people with a covenant of love and fidelity, so our Savior, the spouse of the Church, now encounters Christian spouses through the sacrament of Matrimony.”
