Some may disagree, but many conservative scholars maintain that there are certain scriptural grounds for divorce and remarriage. There are no scriptural grounds for sodomy.
I’ve heard one very fundamentalist congregation teach that if a wife is defiantly unfaithful, the husband may divorce her and remarry. But the woman doesn’t have this same option; she may not remarry as long as he lives. He gave a scriptural reference which made sense at the time, but I can’t think of it.
