When rightly understood, Gen. 2:24-25 and Eph. 5: 21-33 provide an almost formula-like description for a pleasurable, loving, faithful marriage of oneness built on equality and mutuality. Modern science teaches what the writers of Genesis and Ephesians could not have known.
Explorations of Genesis 2 intent on recovering God's ideal for the interrelationship between male and female often zoom in on the creation of Eve. We are better able to appreciate how the narrative supports that ideal when we engage the whole chapter.
