The Bible teaches marriage is the lifelong covenant union of one man and one woman, instituted by God at creation. Christian marriage signifies Christ's union with his church — husbands love sacrificially, wives respect, both serve. Divorce is permitted only in cases of unfaithfulness or abandonment.
Marriage is the oldest of biblical institutions — established by God at creation, before the fall. Genesis 2:24 is the foundational text: 'Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.' Jesus reaffirmed this in Matthew 19:4-6, quoting Genesis 2 and adding: 'What therefore God hath joined together, let not man put asunder.' Marriage is therefore not a human invention adapted by religion but a divine institution from the beginning. Five biblical principles define Christian marriage. (1) Covenant — not contract. Marriage is based on lifelong commitment, not exchange. Malachi 2:14 — 'the wife of thy covenant.' (2) One man and one woman. Genesis 2 establishes male and female as complementary; Jesus (Matthew 19:4-5) repeats this as the foundational pattern. (3) Lifelong — 'till death do us part' is biblical (Matthew 19:6). (4) Exclusive — sexual fidelity is required (Hebrews 13:4). (5) Ordered toward family — though not all marriages produce children, marriage is biblically connected with the formation of family. Ephesians 5:21-33 is the most extensive New Testament passage on Christian marriage. Paul makes a stunning theological claim: Christian marriage signifies Christ's union with his church (5:32). Husbands are to love wives 'as Christ also loved the church, and gave himself for it' (5:25) — sacrificial, costly, life-giving love. Wives are to respect husbands 'as unto the Lord' (5:22) and respond to their leadership. Both submit to one another (5:21) in mutual service. Together, Christian husbands and wives display the gospel through their marriage. The roles in Ephesians 5 have been variously interpreted across traditions. All traditions affirm sacrificial love from husbands and respect from wives. Complementarian traditions (most evangelical, Catholic, Orthodox) understand the husband as having a particular leadership role; egalitarian traditions emphasize mutual submission and shared leadership. Both views are held by Christians of equal sincerity. The Bible permits divorce in only two situations. (1) Unfaithfulness — Matthew 19:9: 'whosoever shall put away his wife, except it be for fornication, and shall marry another, committeth adultery.' (2) Abandonment by an unbelieving spouse — 1 Corinthians 7:15: 'But if the unbelieving depart, let him depart. A brother or a sister is not under bondage in such cases.' Beyond these two situations, the Bible commands faithfulness through difficulty. 1 Corinthians 7 also addresses many marital situations: singles, widows, those married to unbelievers. The chapter establishes celibacy as a legitimate gift (7:7) and lifts up marriage as honorable. Hebrews 13:4 — 'Marriage is honourable in all, and the bed undefiled.' The Bible also addresses singleness positively. Jesus himself never married; Paul wrote 1 Corinthians 7 as a single. Singleness can be a gift for kingdom service (1 Corinthians 7:32-35) and is not a lesser state than marriage. Both married and single Christians serve God in the form of life he has given them.
“Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.”
“What therefore God hath joined together, let not man put asunder.”
“Husbands, love your wives, even as Christ also loved the church, and gave himself for it.”
“This is a great mystery: but I speak concerning Christ and the church.”
“Marriage is honourable in all, and the bed undefiled.”
Christian marriage is built one decision at a time. (1) Commit to lifelong covenant — not contingent on happiness. (2) Husbands: love sacrificially — the test is Christ's love for the church. (3) Wives: respect and partner — Ephesians 5:33. (4) Both: pray together — couples who pray together separate at dramatically lower rates. (5) Both: prioritize the marriage above career, hobbies, even children. (6) Both: serve each other. (7) When conflict comes: forgive quickly (Matthew 6:14-15), reconcile fast (Ephesians 4:26), and seek help when needed.
The Bible permits divorce in two situations: (1) Unfaithfulness — Jesus said 'whosoever shall put away his wife, except it be for fornication, and shall marry another, committeth adultery' (Matthew 19:9). (2) Abandonment by an unbelieving spouse — 1 Corinthians 7:15. Beyond these, the Bible commands faithfulness through difficulty. Catholic teaching does not recognize divorce (a valid marriage cannot be dissolved) but does recognize annulment; Orthodox and most Protestant traditions accept the biblical exceptions for divorce and remarriage.
Ephesians 5:25 — 'Husbands, love your wives, even as Christ also loved the church, and gave himself for it.' The husband's love is to be sacrificial, like Christ's: laying down his own preferences for his wife's good. Ephesians 5:23 calls him 'head' of his wife, but the headship is exercised in self-giving service, not domination. Colossians 3:19 — 'Husbands, love your wives, and be not bitter against them.' 1 Peter 3:7 — husbands are to dwell with wives 'according to knowledge,' giving 'honour unto the wife.'
Ephesians 5:22 — 'Wives, submit yourselves unto your own husbands, as unto the Lord.' Ephesians 5:33 — 'the wife see that she reverence her husband.' The Bible calls wives to respect and partner with their husbands' servant leadership. The submission is voluntary, given in response to husbands who love sacrificially. Proverbs 31 presents an extended portrait of a strong, capable, godly wife who manages a household and businesses, is honored by her husband and children, and is praised in the community.
Yes — the Bible consistently treats sexual activity outside marriage as sin. Hebrews 13:4 — 'Marriage is honourable in all, and the bed undefiled: but whoremongers and adulterers God will judge.' 1 Corinthians 6:18 — 'Flee fornication.' The biblical pattern is that sex belongs within the covenant of marriage. This includes both pre-marital sex (1 Corinthians 7:8-9) and adultery (Exodus 20:14). The Christian sexual ethic is challenging in any culture, but the biblical witness is consistent across both Testaments.
