What a curious claim–that the Bible does, or does not, define marriage in one way or another! It is certainly, as you say, a meaningless claim either way, and claimants from either side seem unable to operate outside a rank fundamentalist hermeneutic.
Also, it is a matter of continued interest to me that historians seem to feel themselves qualified to render theological judgments. Perhaps it is time to remind them that their training does not render them competent to do so, just as stridently as some of them tend to tell “theologians” (a term of opprobrium) that they are not competent historians or even biblical scholars.
