Moving on…. Yesterday I summarized James Brownson’s argument that when the author of Genesis says that a man leaves his mother and father and clings to his wife so that they become “one flesh”, he does not mean that they become a sexual union; he means that they become the basis for a new family group. What lies behind the idea of the man and woman becoming “one flesh” is not their sexual complementarity for the purpose of procreation. It is their genetic similarity for the purpose of forming a new kinship bond.
He then rather muddies this elegant distinction by suggesting that there is, nevertheless, an implied link between kinship and sexuality. The one flesh relationship “flows from sexual union, but is distinct from that sexual union, and is expressed in ways that extend beyond sexual union alone” (87). The reason for this complication is that although the Hebrew word translated “cleave” or “cling” in Genesis 2:24 (dabaq) does not have sexual connotations elsewhere in scripture, Paul speaks of a man being “joined” to a prostitute so as to become “one flesh” with her (1 Cor. 6:16). The Greek word for this joining is kollaō, which is related to the verb proskollēthēsetai, meaning “will be joined” in the Septuagint translation of Genesis 2:24.
