I know these are personal issues, and from the sound of it, your wife left you, which is completely different from what I was describing. I was thinking of situations I know of in which a spouse is known to have cheated, but wants to make amends, and the other spouse refuses and claims his biblical right to divorce.
As I said, I have no biblical grounds from this passage to tell him he is wrong, but other passages regarding forgiveness seem to point to a different path.
I think Paul's teachings about abandonment (1 Cor. 7) would apply in this situation.
I agree, and I want to stress that I understand that you did not intend to make a blanket statement and that your heart was not to condemn. However, I wanted to put a bit of my story into this conversation to remind everyone that these situations are often very messy and difficult, and that there truly is an "innocent" party to divorce, to the degree that a person has consistently treated his/her spouse with grace, compassion, deference, love, etc., and provided security for them in the relationship. And folks in the middle of these types of situations know that they can't tell other people what they are enduring if they ever hope to rescue their marriage because it will betray the confidentiality of the relationship and make it very difficult to extend grace if things can actually be resolved. For instance, I couldn't tell anyone in my family was went on until after the divorce was finalized because if I had they would have not been able to forgive my ex-wife and it would have made it very difficult for us to have a good marriage. I also needed to avoid talking to friends about it because it would undermine the confidentiality of the relationship and possibly poison our dealings with others, putting an enormous strain on the marriage.
However, most people who have never been in that situation haven't had to think through those issues (praise God!) and all they know is that a marriage "suddenly" comes apart and they assume that it was done hastily since they didn't have advance notice of trouble. Therefore, no matter what the circumstances, both the husband and wife get condemned for simply giving up and people piously conclude that "there are no innocent parties in divorce." I've personally and specifically been offered that chestnut of wisdom/condemnation from all sorts of people, from Southwestern Seminary President Ken Hemphill to a nervy teenaged-boy 'prophet' who wanted me to repent of my sin right there in the hallway at church.
And what really got under my skin was a seminary student co-worker who confessed to me that he was currently cheating on his wife with another woman, but that I should follow his example and not divorce my wife. (He, of course, assumed that I was cheating on my spouse too.) He couldn't understand why I was appalled at his behavior since "the Bible clearly teaches that David committed adultery, but he was still a 'man after God's own heart,' but the scripture clearly teaches that there's not excuse for divorce." The irony of it was that he consistently condemned
me for "not believing the Bible" (in the manner of the Conservative Resurgence) and for not being a Five-Point Calvinist -- let me note here that I don't consider this person a good representative of the Conservative Resurgence movement, a Five-Point Calvinist, or a Christian, and he is no longer in vocational ministry since his wife ended up divorcing him for infidelity and physical abuse -- the guy was a sociopath. Of course that didn't stop him from leading the charge of condemnation against me for violating the ban on divorce. Unfortunately, that guy is not a law enforcement officer...
