So Time magazine has now picked up on an ongoing recent dialogue between John Piper and David Instone-Brewer. Here's a clip and here is the link to the TIME article so you can read the whole thing:
Instone-Brewer radically reinterprets the first passage using, of all things, quotation marks. The Greek of the New Testament didn't always contain them, and scholars agree that sometimes they must be added in to make sense of it. Instone-Brewer, an expert in Jewish thought during Jesus's era, writes that Christ's interlocutors were not asking him whether there was any cause at all for divorce, but whether he supported something called "any-cause" divorce, a term a little bit like "no-fault" that allowed husbands to divorce wives for any reason at all. Instone-Brewer claims Jesus's "no" was a response to this idea, and that his "except for sexual indecency" condition was not a statement of the sole exemption from God's blanket prohibition, but merely Christ's reiteration of one of several divorce permissions in the Old Testament — one he felt the "any-time" advocates had exaggerated. Finally, Instone-Brewer tallies four grounds for divorce he finds affirmed in both Old and New Testaments: adultery, emotional and sexual neglect, abandonment (by anyone) and abuse.
