These texts lead Christians to a shared conviction that marriage is meant to be faithful and enduring. They also produce real disagreement about divorce, separation, and whether remarriage is permitted after a marriage has ended.
Quick Answer
The Bible presents marriage as a lifelong union and speaks strongly against faithless, self-serving divorce. When Jesus is questioned about divorce, he points back to God’s purpose in creation rather than treating divorce as an ordinary solution to marital conflict.
Christians differ over several passages. Matthew records Jesus mentioning an exception for “sexual immorality,” while Mark and Luke state the warning about divorce and remarriage without recording that exception. Paul addresses a believer whose unbelieving spouse chooses to leave and says that the believer is “not bound in such cases” (1 Corinthians 7:15, BSB).
Roman Catholic, Eastern Orthodox, and Protestant churches all affirm the seriousness of marriage, but they reach different conclusions about whether divorce ends a marriage before God and whether a divorced person may remarry while a former spouse is living.
Marriage as the Starting Point
The Bible’s starting point is not divorce law but God’s purpose for marriage. Genesis describes husband and wife forming a new family bond:
“For this reason a man will leave his father and mother and be united to his wife, and they will become one flesh.” —Genesis 2:24, BSB
Jesus quotes this passage when questioned about divorce:
“So they are no longer two, but one flesh. Therefore what God has joined together, let man not separate.” —Matthew 19:6, BSB
Divorce is therefore not treated merely as a legal procedure. The biblical concern includes covenant faithfulness, sexual integrity, justice toward a spouse, and the enduring character of marriage.
This context matters because divorce in the ancient world could leave a woman economically and socially vulnerable. Jesus’ teaching confronts the idea that a spouse can be dismissed and replaced at will.
Key Bible Passages
| Passage | What it addresses | Why it matters |
|---|---|---|
| Genesis 2:18–25 | Marriage as a “one flesh” union | Jesus uses creation as the foundation for his teaching. |
| Deuteronomy 24:1–4 | A certificate of divorce and a later marriage | Regulates an existing divorce situation; it does not command divorce. |
| Malachi 2:10–16 | Covenant betrayal within marriage | Condemns treachery and faithlessness toward a spouse. |
| Matthew 5:31–32 | Divorce and remarriage | Includes Matthew’s exception for “sexual immorality.” |
| Matthew 19:3–12 | Jesus’ response to a divorce dispute | Contrasts Moses’ concession with God’s creation purpose. |
| Mark 10:2–12 | Divorce and remarriage | States Jesus’ warning without recording Matthew’s exception. |
| Luke 16:18 | Divorce and remarriage | Gives a brief warning about marrying after divorce. |
| 1 Corinthians 7:10–16 | Separation and mixed-belief marriages | Addresses reconciliation, abandonment, and peace. |
These passages do not all answer the same question. Deuteronomy concerns Israelite civil law. Jesus responds to disputes about marriage and divorce. Paul offers pastoral instruction to Christians facing difficult marital circumstances.
Old Testament Background
Deuteronomy 24:1–4
Deuteronomy 24 describes a man giving his wife a certificate of divorce, her becoming another man’s wife, and a restriction on the first husband marrying her again after the later marriage ends.
The law does not tell an Israelite man to divorce his wife. It regulates what happens after divorce has already occurred. Jesus addresses this background in Matthew 19, saying that Moses permitted divorce because of the people’s “hardness of heart” before directing his listeners back to creation.
Deuteronomy recognizes a broken situation; it does not replace the biblical ideal of faithful marriage.
Malachi 2:10–16
Malachi speaks against men who acted treacherously toward “the wife of your youth.” The prophet connects marital betrayal with corrupt worship and injustice within the community.
English translations differ over the difficult wording of Malachi 2:16. Some render it as God hating divorce, while others emphasize the violence and wrongdoing of the man who divorces. The surrounding passage is clear: God condemns betrayal, faithlessness, and violence within marriage.
Jesus’ Teaching on Divorce
Matthew 5 and Matthew 19
In the Sermon on the Mount, Jesus says:
“But I tell you that anyone who divorces his wife, except for sexual immorality, causes her to become an adulteress, and anyone who marries a divorced woman commits adultery.” —Matthew 5:32, BSB
Matthew 19 records a fuller exchange. The Pharisees ask whether divorce is lawful “for any reason.” Jesus answers by quoting Genesis and emphasizing that husband and wife are one flesh. When asked why Moses permitted a certificate of divorce, Jesus says that Moses allowed it because of hardness of heart.
Matthew records Jesus saying:
“Now I tell you that whoever divorces his wife, except for sexual immorality, and marries another woman commits adultery.” —Matthew 19:9, BSB
The major debate centers on the Greek word porneia, translated here as “sexual immorality.” Many Protestant interpreters understand it to include marital sexual unfaithfulness. Others give it a narrower meaning, such as an unlawful union or a sexual offense connected with Jewish betrothal.
That difference affects the question of remarriage. A broad reading may permit divorce after sexual unfaithfulness. A narrow reading leaves much less room for remarriage after divorce.
Mark and Luke
Mark states the warning in direct language:
“Whoever divorces his wife and marries another woman commits adultery against her. And if a woman divorces her husband and marries another man, she commits adultery.” —Mark 10:11–12, BSB
Luke similarly says:
“Anyone who divorces his wife and marries another woman commits adultery, and the man who marries a divorced woman commits adultery.” —Luke 16:18, BSB
Because Mark and Luke do not mention an exception, some Christians conclude that remarriage is not permitted while a former spouse is alive. Others read the Gospel accounts together and understand Matthew’s exception as a qualification of Jesus’ teaching even when Mark and Luke do not repeat it.
Paul’s Teaching in 1 Corinthians 7
Paul first addresses marriages between Christians:
“To the married I give this command (not I, but the Lord): A wife must not separate from her husband. But if she does, she must remain unmarried or else be reconciled to her husband. And a husband must not divorce his wife.” —1 Corinthians 7:10–11, BSB
Paul assumes that separation can occur, but he does not present separation as a casual route to another marriage. His stated alternatives are remaining unmarried or reconciliation.
He then considers a believer married to an unbeliever. If the unbelieving spouse is willing to remain in the marriage, the believer should not pursue divorce. But Paul adds:
“But if the unbeliever leaves, let him go. The brother or sister is not bound in such cases. God has called you to live in peace.” —1 Corinthians 7:15, BSB
The phrase “not bound” is another central disagreement. Some Christians understand it as freedom to remarry after abandonment. Others understand it more narrowly: the believer is not required to stop the departing spouse from leaving, but remarriage is still not permitted.
Where Christian Traditions Differ
| Tradition or approach | Divorce | Remarriage |
|---|---|---|
| Roman Catholic | Civil divorce may sometimes be necessary for legal, financial, or protective reasons, but it does not end a valid sacramental marriage before God. | Not permitted while a valid spouse is living. A declaration of nullity may find that a valid marriage bond was absent from the beginning. |
| Eastern Orthodox | May be permitted in limited circumstances as a pastoral accommodation through oikonomia. Practice varies among churches and jurisdictions. | A later marriage may be allowed in limited circumstances and is often treated penitentially. |
| Many Protestant churches | Often permitted for sexual unfaithfulness and abandonment by an unbelieving spouse. | Often permitted after sexual unfaithfulness or abandonment. |
| Protestants limiting remarriage | Civil divorce or separation may occur in grievous circumstances, while the marriage bond is understood to continue. | Not permitted while a former spouse is living. |
Roman Catholic Teaching
The Roman Catholic Church teaches that a valid sacramental marriage between baptized persons is indissoluble. Civil divorce can sometimes be necessary for legal responsibilities, finances, or protection, but it does not by itself end a valid marriage in the Church’s understanding.
A declaration of nullity is not Catholic divorce. It is a finding that a valid marriage bond was absent from the beginning because an essential condition of valid consent or capacity was lacking.
Eastern Orthodox Practice
Eastern Orthodox churches affirm lifelong marriage and take Jesus’ teaching seriously. Many Orthodox jurisdictions have historically allowed divorce and a later marriage in limited situations through oikonomia, a pastoral accommodation in response to human brokenness.
A later marriage may be treated penitentially rather than as a repeat of a first marriage.
Protestant Approaches
Many Protestant churches read Matthew’s exception as applying to adultery within marriage and understand 1 Corinthians 7:15 to permit remarriage after abandonment by an unbelieving spouse.
Other Protestants emphasize Mark 10, Luke 16, and Paul’s instruction that a separated spouse should remain unmarried or be reconciled. They may permit civil divorce or separation in grievous circumstances while maintaining that remarriage is not permitted as long as a former spouse lives.
Some Protestant interpreters also apply covenant-abandonment language to severe abuse. The Bible does not use modern categories for every form of abuse discussed in churches and courts. Immediate safety and separation from danger, however, are not the same question as whether a divorce or later remarriage is permitted.
What Christians Commonly Share
Despite substantial differences, major Christian traditions generally agree that:
- Marriage is a serious covenant rather than a temporary arrangement.
- Jesus presents faithful, lifelong union as God’s intention for marriage.
- Divorce is not morally trivial, especially where it involves betrayal, exploitation, or abandonment.
- Reconciliation is valued where it is possible and appropriate.
- Civil divorce and the status of a marriage before God are not always treated as identical questions.
Common Misreadings
“The Bible gives one simple rule about divorce.”
The relevant material includes creation, Israelite law, prophetic critique, Jesus’ teaching, and Paul’s pastoral counsel. A short answer can miss the different situations those passages address.
“Deuteronomy 24 commands divorce.”
It does not. The passage regulates an existing practice involving divorce and remarriage. Jesus does not present it as God’s creation pattern for marriage.
“Sexual immorality has only one meaning in Matthew.”
The meaning of porneia is disputed. That debate is one reason Christians disagree over whether Matthew permits divorce and remarriage after adultery.
“All Christian denominations teach the same thing.”
They do not. Roman Catholic teaching, Orthodox practice, and Protestant interpretations differ on annulment, abandonment, divorce, and remarriage.
“These passages require someone to remain in danger.”
Biblical teaching about marriage should not be used to minimize violence, coercion, or abuse. Safety and separation from danger must not be confused with approval of harm.
FAQ
Does the Bible allow divorce for adultery?
Many Christians answer yes, based on Matthew 5:32 and Matthew 19:9, where Jesus includes an exception for “sexual immorality.” Others interpret porneia more narrowly and do not see it as a general permission for divorce and remarriage after adultery.
Does the Bible allow remarriage after divorce?
Christian traditions answer differently. Many Protestant churches allow remarriage after divorce for sexual unfaithfulness or abandonment. Roman Catholic teaching does not recognize remarriage after a valid marriage while the former spouse is living, though a declaration of nullity may determine that no valid marriage existed. Orthodox churches often permit a later marriage in limited circumstances.
What does “not bound” mean in 1 Corinthians 7:15?
Some interpreters understand Paul’s phrase as freedom to remarry after an unbelieving spouse abandons the marriage. Others understand it as freedom from the obligation to preserve a marriage the departing spouse has rejected, without permission for remarriage.
Why do Matthew, Mark, and Luke sound different?
Matthew includes an exception for sexual immorality, while Mark and Luke record Jesus’ warning without that wording. Some readers see Matthew as supplying a qualification for all three accounts. Others see Matthew’s wording as addressing a narrower Jewish legal or betrothal setting.
Conclusion
The Bible presents marriage as a faithful, enduring one-flesh union. Divorce is treated as a serious rupture rather than a routine answer to conflict, and remarriage raises the question of whether the original marriage bond remains.
The major disagreements turn on how Matthew’s exception for porneia should be understood, how Matthew relates to Mark and Luke, and whether Paul’s statement that an abandoned believer is “not bound” includes freedom to remarry. Those questions explain why Christians with a high view of marriage can still reach different conclusions.
