“The matrimonial covenant, by which a man and a woman establish between themselves a partnership of the whole life, is by its nature ordered toward the good of the spouses and the procreation and education of offspring; this covenant between baptized persons has been raised by Christ the Lord to be the dignity of a sacrament” (CCC #1601).
“Sacred Scripture begins with the creation of man and woman in the image and likeness of God and concludes with a vision of ‘the wedding-feast of the Lamb’ (CCC #1602).
Scripture speaks throughout of marriage and its ‘mystery,’ its institution and the meaning God has given it, its origin and its end, its various realizations throughout the history of salvation, the difficulties arising from sin and its renewal ‘in the Lord’ in the New Covenant of Christ and the Church” (CCC #1602).
“The intimate community of life and love which constitutes the marriage state has been established by the Creator and endowed by him with its own proper laws. ‘ . . . God himself is the author of marriage.’ 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” (CCC #1603).
“The marriage covenant, by which a man and woman form with each other an intimate communion of life and love, has been endowed with its own special laws by the Creator. By its very nature it is ordered to the good of the couple, as well as to the generation and education of children. Christ the Lord raised marriage between the baptized to the dignity of a sacrament” (CCC #1660).
