Short answer: Scripture's core marriage texts describe a covenant union rather than a contract — Genesis 2:24's "one flesh," which Jesus cites in Mark 10:9 as something God joins. The command aimed at husbands in Ephesians 5:25 is self-sacrifice modeled on the cross, and the most-read wedding passage, 1 Corinthians 13:4-7, was not written about marriage at all.
Here are eight passages, grouped by theme, including where faithful Christians read them differently.
Marriage as covenant union
Genesis 2:24 is the foundation text, quoted by Jesus and by Paul: "Therefore a man will leave his father and his mother, and will join with his wife, and they will be one flesh."
Three movements: leave, join, become one flesh. The leaving comes first — a new household with a primary loyalty of its own.
Jesus cites this passage and draws the conclusion in Mark 10:9: "What therefore God has joined together, let no man separate." The claim is that a third party is involved. Marriage in this view is not merely two people's agreement, which is why Scripture treats it as a covenant rather than a contract.
Proverbs 18:22 adds the note of gift: "Whoever finds a wife finds a good thing, and obtains favor of Yahweh."
The command to love sacrificially
Ephesians 5:25 sets the bar for husbands: "Husbands, love your wives, even as Christ also loved the assembly, and gave himself up for it."
The standard is a man who died. Whatever else this passage is doing, the specific instruction to husbands is self-expenditure, not self-assertion.
1 Peter 3:7 continues in the same direction: "You husbands, in the same way, live with your wives according to knowledge, giving honor to the woman, as to the weaker vessel, as being also joint heirs of the grace of life; that your prayers may not be hindered."
Two things stand out. Wives are named joint heirs — equal in inheritance. And a husband's failure here is said to obstruct his prayers, which is a striking consequence.
Colossians 3:14 supplies the binding agent: "Above all these things, walk in love, which is the bond of perfection."
Two who hold each other up
Ecclesiastes 4:9-12 is not written specifically about marriage, but it is read at weddings for good reason: "Two are better than one, because they have a good reward for their labor. For if they fall, the one will lift up his fellow; but woe to him who is alone when he falls, and doesn't have another to lift him up. Again, if two lie together, then they have warmth; but how can one keep warm alone? If a man prevails against one who is alone, two shall withstand him; and a threefold cord is not quickly broken."
The wedding passage that isn't about weddings
1 Corinthians 13:4-7: "Love is patient and is kind; love doesn't envy. Love doesn't brag, is not proud, doesn't behave itself inappropriately, doesn't seek its own way, is not provoked, takes no account of evil; doesn't rejoice in unrighteousness, but rejoices with the truth; bears all things, believes all things, hopes all things, endures all things."
Paul wrote this to a divided church quarreling over spiritual gifts, not to a couple. That does not disqualify it from weddings — it arguably strengthens it. This is what love looks like among people who are genuinely difficult to love, which is a more useful standard for a marriage than a description of romance.
Where Christians differ
This is a subject where sincere Christians read the same texts differently, and it would be dishonest to flatten it.
On authority and roles. Ephesians 5:21-33 is the center of the disagreement. Complementarians read Paul's instructions as establishing distinct and enduring roles, with husbands bearing a self-sacrificial headship modeled on Christ and wives called to submission, citing Ephesians 5:22-24 and 1 Peter 3:1. Egalitarians point to Ephesians 5:21 — "subjecting yourselves to one another in the fear of Christ" — as the heading that governs everything after it, and to Galatians 3:28, reading the passage as mutual submission expressed in the household forms of the first century. Both sides affirm that the husband's command is cruciform love, and both reject any reading that licenses domination.
On divorce. Jesus speaks against it in Mark 10:2-12 and names an exception in Matthew 19:9; Paul addresses another situation in 1 Corinthians 7:15. Traditions differ substantially on what these permit — from the Catholic teaching on indissolubility and annulment to Protestant readings that recognize biblical grounds for divorce and remarriage.
A necessary pastoral note. No Christian tradition teaches that these passages require anyone to remain in danger. Malachi 2:16 records God's hatred of the violence a man does to his wife, and Ephesians 5:29 assumes a husband nourishes and cherishes. Scripture on marriage has been misused to keep people in abusive situations; that is a misuse, and anyone in danger should seek immediate help and safety.

How to apply it today
Read your own instructions first. The most common misuse of Ephesians 5 is reading your spouse's verse to them. Paul addresses each party directly; whatever your view of the roles, the paragraph aimed at you is the one you are accountable for.
Measure by 1 Corinthians 13, not by feeling. Substitute your own name into "love is patient, love is kind" and read it as a diagnostic. It was written for people who found each other difficult.
Treat it as covenant, which means the vow outlives the mood. Mark 10:9 locates the binding in God's action rather than in ongoing enthusiasm. That is what makes it a refuge rather than a performance review.
Get help early. Ecclesiastes 4:12's threefold cord is usually read as God woven into the marriage; it applies to counsel and community too. Most marriages that get help get it years later than they should have.
Frequently Asked Questions
What does "the two shall become one flesh" mean? Genesis 2:24 describes a union that is physical but broader than physical — a new kinship where two separate people and histories become a single household and, in the text's language, a single flesh. The verse's first movement is "leave," establishing a new primary loyalty distinct from the families of origin. Jesus quotes this passage in Mark 10:6-9 and draws from it the conclusion that God is the one doing the joining, which is why Scripture treats marriage as a covenant rather than an agreement two people can simply dissolve.
What does the Bible say about a husband's role? Ephesians 5:25 is the central command and it is unambiguous: love your wife as Christ loved the church and gave himself up for it — the standard is a man who died. 1 Peter 3:7 adds honoring her as a joint heir of the grace of life, and warns that failure here hinders a husband's prayers. Christians differ on whether the surrounding passage establishes enduring distinct roles (the complementarian reading) or describes mutual submission per Ephesians 5:21 (the egalitarian reading), but every tradition agrees the husband's own instruction is self-sacrifice, not authority-taking.
Why is 1 Corinthians 13 read at weddings if it isn't about marriage? Paul wrote it to the church at Corinth, which was fracturing over status and spiritual gifts — the chapter is a rebuke to people who were proud and impatient with each other. Read that way it is arguably better wedding material than a romantic passage would be, because it defines love as behavior toward people who are hard to love rather than as a feeling. Its qualities — patient, kind, not self-seeking, not easily provoked, enduring — describe exactly what marriage requires on ordinary days.
Does the Bible ever allow divorce? Christians differ significantly, and the difference rests on real texts. Jesus speaks against divorce in Mark 10:2-12 and states an exception for sexual immorality in Matthew 19:9; Paul addresses a believer abandoned by an unbelieving spouse in 1 Corinthians 7:15. Roman Catholic teaching holds a valid sacramental marriage indissoluble and addresses cases through annulment; many Protestant traditions recognize biblical grounds for divorce and remarriage, with ongoing debate about how far those grounds extend. All traditions agree that no passage requires anyone to remain in physical danger — anyone facing abuse should seek help and safety immediately.
