Only the cynic would dwell on the possibility of that statement meaning that a husband could sacrifice his wife for the marriage. While a Wife is given to a Husband by God, she belongs to God and the Marriage as much as she does to him, just as he belongs to God and the Marriage and his Wife. We cannot offer in sacrifice that which is not ours completely – by definition that would not be a sacrifice. It would be theft and a disingenuous offering.
