I laughed. 
I followed a couple links and found quotes she cited as “proof” that complementarians believe that divorce is wrong even with Biblical justification:
I don’t think the Bible allows divorce and remarriage ever while the spouse is living.
JOHN PIPER, WHAT JESUS DEMANDS FROM THE WORLD (WHEATON, IL: CROSSWAY BOOKS, 2006), 303.
Seems clear even from this brief quote that Piper is talking about remarriage after divorce, not the divorce itself. I haven’t read the context of this quote, but I remember Piper spent about a chapter (appendix?) making this case in his book This Momentary Marriage.
Taken together, Jesus and Paul teach that divorce is not an option for believers. The only exceptions that they allow are in cases of immorality or desertion. Neither Jesus nor Paul says that a person must be divorced if there is infidelity or desertion . They are simply saying that it can be permissible in those two situations … Nevertheless, covenant faithfulness within marriage sends a message to the world about Christ’s covenant faithfulness to his bride. For this reason, upholding this icon of the gospel ought to be a matter of first importance to every Christian spouse – even when that spouse has what would otherwise be legitimate grounds for dissolving the marriage.
DENNY BURK, WHAT IS THE MEANING OF SEX? (WHEATON, IL: CROSSWAY, 2013), 134-135, EMPHASIS ORIGINAL.
The ellipsis in this quote seems awfully conspicuous. If anyone has access to the source on this one, I’d be interested to know what’s been omitted. But even disregarding that, what’s controversial about this quote? Should emulating Christ’s covenant faithfulness not be of first importance in a marriage where these sins are present? Shouldn’t reconciliation and restoration of the marriage always be Plan A and divorce always be Plan B, done only when it’s determined Plan A is not possible?
This use of sources is either careless or dishonest. If this is at all representative of the book, it doesn’t bode well.
