I just listened to that part of my sermon on “Divorce and Remarriage” to which you refer, the part talking about Deuteronomy 24. After listening to it, I can see why. The Mosaic law was binding in the Old Testament. But in the New Testament, I believe I can say confidently, it no longer applies. My proof is I Corinthians 7:10-11: “… But and if she depart, let her remain unmarried, or be reconciled to her husband …” Paul stipulates that if a husband or wife departs from his or her spouse (implication being that one of them committed adultery, which is the only ground for divorce), then he or she must remain unmarried or be reconciled to the spouse. Thus, a husband may take back his adulterous wife, and a wife may take back her adulterous husband, if the guilty party is sorry. I believe this still holds true even if the adulterous wife or husband has remarried, and then divorced the second spouse. I apologize for the confusion in my sermon which you listened to. I should have been clearer about that.
