The Bible addresses divorce with seriousness, especially when it involves adultery. In the Gospels of Matthew and Mark, Jesus teaches that while God’s original design for marriage is lifelong commitment, He allows divorce in cases of sexual immorality. Matthew includes what’s often called the “exception clause,” stating that adultery is a valid reason for divorce (Matthew 5:31–32, 19:3–9). Mark’s version doesn’t mention this exception, emphasizing the general rule that divorce and remarriage lead to adultery (Mark 10:2–12). These differences reflect Jesus’ deep concern for both the sanctity of marriage and the pain caused by betrayal.
Ultimately, the Bible doesn’t command divorce after adultery—it permits it. Forgiveness and reconciliation are still on the table for those who choose it. This balance of truth and grace offers direction, not just rules. If you’re navigating this tough issue, there’s wisdom and clarity in Scripture that can guide your decisions. Keep reading for a deeper dive into what these verses really say and how they apply to your life today.
Divorce is one of the most sensitive and often misunderstood topics in Christianity. If you’re wondering what the Bible actually says about divorce—specifically when it involves adultery—you’re not alone. The key passages are found in the Gospels of Matthew and Mark. Let’s break them down clearly, directly, and thoroughly.
Jesus on Divorce: Two Main Sources
The teachings of Jesus on divorce are recorded in:
- Matthew 5:31-32
- Matthew 19:3-9
- Mark 10:2-12
Let’s look at each passage and explain what Jesus meant—especially about divorce due to adultery.
1. Matthew 5:31–32 – The Exception Clause
“It has been said, ‘Anyone who divorces his wife must give her a certificate of divorce.’ But I tell you that anyone who divorces his wife, except for sexual immorality, makes her the victim of adultery, and anyone who marries a divorced woman commits adultery.”
— Matthew 5:31–32 (NIV)
This is often called the “exception clause.” It’s where Jesus directly allows divorce in the case of sexual immorality.
Key Takeaways:
- Jesus is clearly tightening the permissiveness of divorce.
- However, He does allow divorce in cases of sexual sin—the Greek word here is porneia, meaning adultery, fornication, or other immoral acts.
- If there’s no sexual immorality, divorcing someone causes them and the next partner to commit adultery.
Bottom line?
Jesus permits—but doesn’t command—divorce in cases of adultery. He makes it clear that marriage is sacred, and divorce isn’t to be taken lightly.
2. Matthew 19:3–9 – When the Pharisees Test Jesus
This is the longer, more detailed version of the conversation:
“Some Pharisees came to him to test him. They asked, ‘Is it lawful for a man to divorce his wife for any and every reason?’”
— Matthew 19:3
Jesus responds by pointing back to Genesis 2:24, emphasizing God’s original design for marriage:
“Therefore what God has joined together, let no one separate.”
— Matthew 19:6
When the Pharisees push back, citing Moses’ allowance for divorce, Jesus replies:
“Moses permitted you to divorce your wives because your hearts were hard. But it was not this way from the beginning. I tell you that anyone who divorces his wife, except for sexual immorality, and marries another woman commits adultery.”
— Matthew 19:8–9
What Does This Mean?
- Divorce was never God’s original plan.
- Moses allowed it as a concession, not a command.
- Jesus permits divorce only when there’s sexual unfaithfulness.
- Remarriage after a divorce for any other reason is considered adultery.
Again, this supports the idea that adultery is the only biblically justified reason for divorce according to Jesus in Matthew.
3. Mark 10:2–12 – No Exceptions Mentioned
Mark’s Gospel gives a stricter version:
“Anyone who divorces his wife and marries another woman commits adultery against her. And if she divorces her husband and marries another man, she commits adultery.”
— Mark 10:11–12
Notice something missing?
There’s no exception clause here. Mark doesn’t mention adultery at all. The teaching is more absolute.
So, Which Is It?
Some believe:
- Matthew gives a specific situation Jesus addressed.
- Mark gives the general principle Jesus taught.
- They’re not contradictory—they’re just focused differently.
Here’s a helpful way to view it:
- General rule: Divorce and remarriage = adultery.
- Exception: If adultery has already occurred, divorce may be morally permitted.
Why Does Jesus Focus So Much on This?
Marriage reflects God’s covenant with His people. That’s why Jesus calls us to a higher standard. He’s restoring marriage to what God originally intended—not just what culture or religious tradition allows.
What About Forgiveness?
Here’s the hard truth: even if someone’s spouse commits adultery, Jesus doesn’t say you must divorce them. He only says it’s permissible.
Options for the Faithful Spouse:
- Forgiveness and reconciliation (if the unfaithful spouse repents).
- Separation or divorce (if trust is broken or abuse continues).
Both are biblical. But choosing to forgive and rebuild is also deeply Christ-like, reflecting God’s forgiveness toward us.
Let’s Be Clear: Divorce Is Not the Goal
Jesus didn’t give people permission to leave their spouse just because things are hard. In fact, in 1 Corinthians 7, the Apostle Paul also calls believers to stay married whenever possible.
“If a woman has a husband who is not a believer and he is willing to live with her, she must not divorce him.”
— 1 Corinthians 7:13
Divorce should always be the last option, not the first reaction.
