What Does the New Testament Teach About Divorce and Remarriage?

In the first two parts of this series, we began where Jesus began. Read those first two posts to make the most sense of this. Context matters. Most importantly, consider the scriptures for yourself, pray, and ask for wisdom. This is not a simple topic.

First, we looked at God’s creation design for marriage: male and female, covenant faithfulness, one flesh, and a union that God Himself joins together.

Then we considered why the Pharisees questioned Jesus about divorce. They were not simply looking for pastoral guidance. They were testing Him within a debate over the circumstances in which a man could dismiss his wife. Jesus refused to begin with loopholes. He exposed the hardness of heart beneath the question and directed them back to God’s intention from the beginning.

But difficult questions remain.

What about adultery?

What if one spouse abandons the marriage?

What if a couple separates?

Does a legitimate divorce permit remarriage?

Why does Matthew include an exception that Mark and Luke do not mention?

What does Paul mean when he says an abandoned believer is “not enslaved”?

The New Testament gives us a clear vision for marriage. Applying that vision in a broken world, however, requires careful reading, humility, and pastoral wisdom.

Let's Begin with the Clear Center

Before examining the most debated passages, we should identify the clear center of the New Testament’s teaching.

• Marriage is intended to be a lifelong covenant.

• Divorce is never treated casually.

• A spouse is not to be discarded simply because a marriage has become difficult, disappointing, or less personally fulfilling.

• Jesus especially condemns divorce when it is used as a way to exchange one spouse for another.

In Mark’s account, Jesus says:

“Whoever divorces his wife and marries another commits adultery against her, and if she divorces her husband and marries another, she commits adultery.”—Mark 10:11–12

Luke records Jesus’ teaching in similarly strong terms:

“Everyone who divorces his wife and marries another commits adultery.”—Luke 16:18

Jesus’ words are intentionally forceful. He is confronting people who wanted to use legal divorce to legitimize covenant unfaithfulness.

A husband could not simply dismiss one wife, marry another, and assume that the proper paperwork made the transition morally innocent. A certificate could make a divorce legally recognizable. It could not make covenant betrayal righteous.

Jesus closes that loophole. Divorce cannot be used to exchange spouses while pretending the original covenant carried no continuing moral significance.

The New Testament discussion begins with permanence, not permission.

Matthew’s Exception

Matthew includes an important phrase that does not appear in Mark or Luke.

Jesus says:

“Everyone who divorces his wife, except on the ground of sexual immorality, makes her commit adultery.”—Matthew 5:32

Later, He says:

“Whoever divorces his wife, except for sexual immorality, and marries another, commits adultery.”—Matthew 19:9

The Greek word translated “sexual immorality” is porneia. It is a broad term that can describe various forms of illicit sexual behavior.

Christians have interpreted Matthew’s exception in several ways. Some understand it to refer to adultery or serious sexual unfaithfulness within marriage. Others believe Jesus was speaking about an unlawful union that should never have been recognized as a legitimate marriage. Still others connect it specifically to sexual betrayal during the Jewish betrothal period.

The most common evangelical interpretation is that Jesus recognizes serious sexual immorality as a grievous violation of the marriage covenant and as legitimate grounds for divorce. But grounds for divorce are not the same thing as a command to divorce.

Sexual betrayal is devastating, but some marriages have experienced genuine repentance, difficult forgiveness, wise counseling, and meaningful restoration. Reconciliation may still be possible.

At the same time, forgiveness must not be reduced to pretending that betrayal was insignificant. Genuine reconciliation requires truth, repentance, accountability, patience, and demonstrated change. This takes time. It also requires godly counselors and a team of people to help a couple navigate. The betrayed spouse should not be pressured to preserve appearances while the offending spouse avoids responsibility.

The presence of biblical grounds for divorce does not create an obligation to divorce.

Why Do Mark and Luke Sound More Absolute?

Matthew includes an exception while Mark and Luke present Jesus’ prohibition without one. Does that mean the Gospel writers contradict one another? Not necessarily.

Teachers often state a moral principle in a concise and forceful form without repeating every possible qualification each time. Other passages may then supply additional context for applying that principle.

Mark and Luke preserve the central force of Jesus’ teaching: Divorce must not become a morally acceptable way to discard one spouse and acquire another. Matthew preserves that same teaching while also recording an exception involving sexual immorality.

Mark and Luke keep us from turning exceptions into convenient escape routes.

Matthew keeps us from acting as though severe sexual covenant betrayal makes no difference.

Understanding the context helps us to avoid reading our culture and situations into theirs. We should allow each Gospel to make its contribution.

Paul Begins with Jesus’ Command

The most extensive New Testament discussion of marriage, separation, and divorce appears in 1 Corinthians 7. Paul begins by appealing directly to Jesus:

“To the married I give this charge—not I, but the Lord—the wife should not separate from her husband … and the husband should not divorce his wife.”—1 Corinthians 7:10–11

When Paul says, “not I, but the Lord,” he is not suggesting that the rest of his teaching is uninspired or unimportant. He is distinguishing between a situation Jesus directly addressed during His earthly ministry and newer pastoral situations that require apostolic application.

For marriages between professing believers, Paul reinforces Jesus’ teaching. Neither spouse should initiate divorce. If separation has already occurred, Paul names two possibilities:

“She should remain unmarried or else be reconciled to her husband.”

Paul does not treat separation as a reset button that automatically opens the way to another marriage. His stated hope is reconciliation. That does not necessarily mean every separation is sinful.

At times, separation may be needed to establish safety, confront destructive behavior, pursue treatment, create accountability, or allow space for repentance. Temporary distance may sometimes serve the hope of genuine restoration. But separation should not be confused with indifference toward the marriage covenant. Paul’s first response is not replacement. It is reconciliation.

Marriage to an Unbeliever

Paul then addresses a situation Jesus did not directly discuss during His public ministry: a Christian married to an unbeliever.

Some believers in Corinth may have wondered whether conversion made their existing marriages spiritually unclean. Should a Christian leave a spouse who did not share the faith? Paul says no.

“If any brother has a wife who is an unbeliever, and she consents to live with him, he should not divorce her.”—1 Corinthians 7:12

The same instruction applies to a believing wife with an unbelieving husband. Conversion does not erase existing covenant responsibilities.

Coming to Christ should make a person more faithful to a spouse, not less. Paul even says that the unbelieving spouse and the children are “made holy” through the believer. He does not mean that they are automatically saved. He means that the marriage and household are not made unclean by the presence of unbelief. God may work through the faithful presence of the believing spouse.

Religious difference alone is not grounds for abandoning a willing spouse. The gospel does not teach us to flee from ordinary covenant difficulty. It teaches us to become more faithful within it.

What If the Unbelieving Spouse Leaves?

Paul then addresses abandonment:

“But if the unbelieving partner separates, let it be so. In such cases the brother or sister is not enslaved. God has called you to peace.”—1 Corinthians 7:15

The believer should not initiate divorce simply because the spouse is an unbeliever.

But if the unbelieving spouse insists on leaving, Paul says, “Let it be so.”

The Christian is not commanded to preserve the appearance of marriage through endless coercion, manipulation, or conflict. One spouse can remain faithful. One spouse cannot manufacture the other person’s faithfulness. A covenant relationship cannot function normally when one party has decisively rejected it.

Paul’s words are both realistic and compassionate:

“God has called you to peace.”

That does not mean Christians should avoid every painful conversation or abandon a marriage at the first sign of conflict. Biblical peace is not the absence of difficulty.

But neither does God require an abandoned spouse to spend the rest of life attempting to control someone who has decisively chosen to leave. The Christian is called to faithfulness but is not given the power to force another person to be faithful.

What Does “Not Enslaved” Mean?

This is where interpretation becomes more disputed.

When Paul says that the abandoned brother or sister is “not enslaved,” does he mean the believer may accept the divorce but must remain unmarried? Or does he mean the believer has been released from the marriage and is therefore free to remarry? Faithful Christians have reached different conclusions.

Some believe divorce may occur in such a situation, but remarriage is not permitted. They emphasize Paul’s earlier instruction to “remain unmarried or else be reconciled.” They also point to Jesus’ strong statements connecting divorce and remarriage with adultery. From this perspective, “not enslaved” means that the believer is not required to prevent the unbelieving spouse from leaving. It does not necessarily mean the believer is free to enter another marriage.

Others believe that a legitimate divorce includes the freedom to remarry. They argue that divorce in the ancient world ordinarily carried the legal right to marry again. They also understand “not enslaved” to mean that the abandoned believer is no longer bound by marital obligations that the other spouse has decisively rejected. From this perspective, it would be inconsistent to recognize that a marriage has genuinely ended while continuing to treat the abandoned person as though the marital bond remained fully intact.

Both sides are attempting to take Scripture seriously.

One emphasizes Jesus’ strong protection of marriage’s permanence. The other emphasizes Paul’s pastoral recognition that abandonment may bring a marriage to an actual end.

The disagreement is not necessarily between Christians who honor marriage and Christians who do not. It is often between believers trying to understand how Jesus’ marriage ideal applies after a spouse has already rejected and abandoned the covenant.

That should make us slower to caricature one another.

What About Abuse?

The New Testament does not contain a verse that says, in modern language, “Abuse is grounds for divorce.” That does not mean Scripture is indifferent to abuse.

The Bible repeatedly condemns violence, oppression, exploitation, threats, deceit, cruelty, and the misuse of power. Husbands are commanded to love their wives as Christ loved the church, not to treat them harshly or cause them harm. A church should never tell a victim that submitting to violence is the same thing as honoring marriage.

Immediate safety matters.

Separation may be necessary.

Children may need protection.

Civil authorities may need to be involved.

Serious abuse must not be treated as an ordinary marital disagreement in which both people are simply told to try harder.

Christians differ over whether patterns of severe, unrepentant abuse should be understood as abandonment, covenant-breaking, or some related biblical category. That discussion deserves careful treatment rather than a quick slogan. One principle, however, should be clear:

The preservation of marriage cannot be separated from the protection of the people within it.

Helping someone reach safety is not the same as encouraging casual divorce. And reconciliation cannot mean returning immediately to the same dangerous conditions after an apology. Biblical repentance produces fruit. It involves truth, responsibility, accountability, and demonstrated change over time.

Reconciliation Is More Than Restoring Appearances

The New Testament consistently values reconciliation. But reconciliation is not the same as pretending nothing happened. It is not avoiding consequences. It is not pressuring a wounded spouse to trust immediately. It is not restoring access before character has been tested.

Real reconciliation requires confession without excuses, repentance without manipulation, accountability without resentment, and change that can be observed over time.

Forgiveness and trust are related, but they are not identical. Forgiveness can begin before trust has been restored. Trust, by its nature, must be rebuilt.

The church should encourage reconciliation where it is honest, safe, and rooted in genuine repentance. It should never confuse reconciliation with preserving appearances at the expense of truth.

What Is Clear Even Where Questions Remain?

Christians may disagree about the precise scope of Matthew’s exception, the meaning of “not enslaved,” and whether every biblically legitimate divorce permits remarriage. But the debated edges should not obscure the clear center.

The New Testament teaches that marriage is a sacred, one-flesh covenant intended to be lifelong. It rejects casual divorce and condemns the use of divorce to exchange one spouse for another. It treats sexual betrayal as a grave violation of the covenant. It calls separated believers toward reconciliation rather than immediately toward replacement.

It instructs Christians not to abandon unbelieving spouses who are willing to remain. It recognizes that an abandoned believer cannot force the departing spouse to preserve the marriage. It refuses to treat every divorce story as morally identical. And it leaves room for grace, repentance, healing, and restoration after serious failure.

Marriage is sacred. Covenant betrayal is serious. Reconciliation matters. Wounded people must be met with both truth and compassion.

We Need Conviction and Compassion

The church has sometimes failed on both sides of this subject. At times, Christians have treated divorce too casually, reflecting the surrounding culture’s view of marriage as a temporary arrangement held together only by personal satisfaction.

At other times, churches have spoken about divorce so rigidly that wounded people felt condemned before anyone had listened to their story. Some divorced people bear significant responsibility for what happened. Others were abandoned, betrayed, or harmed. Many stories contain painful failures on both sides. No two situations are entirely identical.

Faithful pastoral care requires more than applying a label. It requires listening, truth, patience, courage, and confidence in the grace of God.

The New Testament does not give us permission to weaken God’s design for marriage.

Neither does it give us permission to crush people whose lives have been affected by marital brokenness. The church’s task is not to make divorce easy or grace difficult. We need conviction strong enough to honor marriage and compassion deep enough to care for people when marriages break.

Reflection Questions

How does beginning with the permanence of marriage shape the way we understand the New Testament’s exceptions?

Why is it important to distinguish permission to divorce from a command to divorce?

What does Paul’s teaching about an unbelieving spouse reveal about Christian faithfulness?

How can the church pursue reconciliation without minimizing betrayal, abandonment, or danger?

How should Christians respond when faithful interpreters reach different conclusions about remarriage?
