We need to restore the foundation of Biblical marriage
Matt Walsh is wrong with his position that there is never a Biblical justification for divorce. Jesus clearly allows for divorce in the case of adultery, and the Apostle Paul wrote that Christians are free if they are abandoned by an unbelieving spouse. Walsh is right that we should not make the "porneia" exception so broad that it allows every marriage that has ever existed to be nullified, which is why Christians considering divorce should submit to the judgment of godly elders at a Bible-believing church.
But we need to be very clear that God hates divorce, as we see in Malachi 2:16.
Christians can get all self-righteous and holier-than-thou that Walsh is binding where God has not bound in His Word. But the reality is that Matt Walsh is a whole lot closer to Biblical teaching than most "churches" today. The church - specifically Protestants - has utterly failed to abide by God's teaching on un-Biblical divorce. We have no fault divorce all over the church in America. Even worse, by allowing rampant un-Biblical divorce these heretics and apostates are lying about our Savior's relationship with His bride, the church.
I would much rather someone take a no-compromise stance that actually honors marriage than a wishy-washy position that tramples marriage under foot and makes it meaningless.
The sin of our culture today - and the sin of the church today - is not prohibiting divorce where God allows it. The sin of our culture and the church is allowing the marriage covenant to be dissolved willy-nilly with absolutely no reverence for the institution that God created and gave to us. Arguing exceptions to God's general prohibition on divorce is like arguing where the window should be when the house has been totally destroyed all the way to the foundation. A window is meaningless when you put it on top of a pile of ashes. We have to re-build the house and then we can talk about where to put a window.
