What does the Bible say about divorce and remarriage?

The Bible treats divorce and remarriage as a tragic concession, never an ideal. Jesus is unmistakable: God designed marriage as a lifelong, one-flesh covenant, and divorce always falls short of that design. Yet Scripture does not slam every door. It names limited grounds on which divorce is permitted, and where those grounds exist, remarriage is generally permitted too. The heart of the biblical witness is not a loophole hunt but a high view of the covenant a husband and wife make before God.

What the Bible says about God's design

Jesus answers a question about divorce by reaching back behind the law of Moses to the garden. "Haven't you read the Scriptures?" he asks. "They record that from the beginning 'God made them male and female.'... 'a man leaves his father and mother and is joined to his wife, and the two are united into one.' Since they are no longer two but one, let no one split apart what God has joined together" (Matt 19:4-6).

That phrase, "one flesh," is the key. Marriage is not a contract you exit when it stops serving you; it is a covenant that fuses two lives into a single new reality. The Hebrew prophet Malachi puts God's feeling about its rupture plainly: "For I hate divorce!' says the Lord, the God of Israel" (Mal 2:16). When the Pharisees press Jesus about why Moses permitted divorce at all, his answer is searching: "Moses permitted divorce only as a concession to your hard hearts, but it was not what God had originally intended" (Matt 19:8). Divorce is a wound the law bandaged, not a good the law blessed.

The two grounds Scripture recognizes

Christians who take the whole Bible seriously have historically identified two situations in which divorce is permitted and the wronged party is freed to remarry.

The first is sexual unfaithfulness. Jesus gives what is often called the "exception clause": "whoever divorces his wife and marries someone else commits adultery, unless his wife has been unfaithful" (Matt 19:9). The Greek word here is porneia, a broad term for sexual immorality. When one spouse shatters the one-flesh bond through sexual betrayal, the innocent spouse may divorce. Crucially, even here divorce is permitted, not required; forgiveness and rebuilt trust are the better road when the unfaithful partner truly repents.

The second is abandonment by an unbelieving spouse. Paul addresses believers married to those who reject the faith: "But if the husband or wife who isn't a believer insists on leaving, let them go. In such cases the believing husband or wife is no longer bound to the other" (1 Cor 7:15). The phrase "no longer bound" has long been understood to release the deserted believer to remarry. The same logic of covenant-breaking extends, in the judgment of many faithful pastors, to cases of unrepentant abuse, where one spouse has functionally abandoned the protective duties of the marriage even while remaining in the house.

What about remarriage after divorce?

Here serious Christians disagree, and honesty requires naming the range. Some traditions hold that any remarriage while a former spouse lives is adultery, pointing to Jesus' words in Luke 16:18 and to Paul's instruction that a separated wife should "remain single or else be reconciled to him" (1 Cor 7:11). They read marriage as so permanent that only death dissolves it.

The broader evangelical reading, however, is that where divorce was biblically permitted, remarriage is permitted to the innocent party. The exception clause in Matthew 19:9 and Paul's "no longer bound" in 1 Cor 7:15 both attach to the question of remarriage, not merely separation. On this view, a legitimate divorce truly ends the covenant, leaving the wronged spouse free to marry "in the Lord" (1 Cor 7:39).

And what of remarriages that began outside these grounds, perhaps before someone came to faith? Scripture does not counsel breaking up a current marriage to atone for a former one. The call is always forward: repent of what was sinful, receive God's forgiveness, and be faithful in the marriage you are now in. A second marriage entered wrongly does not become more righteous by becoming a third divorce.

Grace for the broken places

It would be a cruelty to teach the Bible's high view of marriage without its higher view of mercy. The God who says he hates divorce is the same God who, through the prophet Hosea, casts himself as a faithful husband to an unfaithful people, vowing, "you will call me 'my husband' instead of 'my master'" (Hos 2:16). To exiled Israel he promises, "your Creator will be your husband" (Isa 54:5). Divorce is never the unforgivable sin. Many readers of these words carry the ache of a marriage that ended, and some bear real guilt. The gospel speaks to both.

At the cross, Jesus took up the covenant we could not keep. He is the faithful Bridegroom who will never leave or forsake his bride, the church (Eph 5:25-32). Every human marriage is a small, cracked mirror of that unbreakable love, and every human failure in marriage is met by a Savior who keeps covenant in our place. If you are divorced, you are not a second-class Christian. If you are wounded, you are seen. If you are wondering whether God can still use a broken story, look at the One whose body was broken to make broken people whole.
