It is often classified as not technically adultery, so spouses are denied the biblical right to divorce. This is mind boggling. Someone who seeks out sexually explicit material and has a physical response to it is in the same mental, physical, and spiritual condition as someone in bed with a coworker. The difference is that the relationship with the coworker is at least private and limited, while porn use accepts and subsidizes an entire industry of sexual sin that is maintained by abuse and slavery, involves hundreds of people, and is tracked by the producing companies and internet servers. Deliberate and repeated porn use is at least adultery, regardless of whether there is repentance at some point. Denying this makes people ask why some pastors are so committed to denying what porn really is. Our pre-technology definition of adultery allows souls and marriages to be ravaged from the inside out because we fail to admit what a porn habit really is. We look away from the institutionalized rape that it subsidizes. Countenancing sexual sin for any reason reveals a poor understanding of sexual sin as well as the gospel.
Do you see how these lies, sometimes borne out of a desire to protect marriage, actually bring about a low view of marriage? By granting, supporting, and even facilitating a biblical divorce, we take a stand to say that we can forgive without being forced to live with people who have shattered us. This protects marriage by allowing the innocent party to leave a relationship that has been broken. By backing biblical divorce, we protect women whom God loves, showing Christ’s love when spouses have not. This protects marriage by refusing to allow sinners to abuse the institution with impunity. By publicly stating that sexual sin and abuse, not wounded spouses, ends marriages, we hold the marriage bed in honor. This protects marriage by creating a holy fear of violating it. By offering biblical divorce, the church affirms that pornography is depravity, and will not be countenanced by Christ’s church. Naming and disciplining sexual sin as the evil it is and offering divorce to the innocent party makes the value of marriage clear as we refuse to see it damaged, abused, or treated lightly.
Developing and maintaining a high view of marriage does a lot. It protects women and children, often the people most hurt by sexual sin. It keeps us from falling into sin ourselves: the higher our view of marriage, the less likely we will be to dabble in something so devastating. And a high view of marriage honors the One who created it for our good and His glory—the One who promises to judge the adulterer and the sexually immoral.
