Genesis 2.7,15,18-24: "So the Lord God caused a deep sleep to fall upon the man, and he slept; then he took one of his ribs and closed up its place with flesh. And the rib that the Lord God had taken from the man he made into a woman and brought her to the man. Then the man said, 'This at last is bone from my bones and flesh from my flesh; this one shall be called Woman, for out of Man this one was taken.'""The marriage covenant, by which a man and a woman form with each other an intimate communion of life and love, has been founded and 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" (CCC 1660).
