Creation ordinance: Genesis 2
Biblical marriage is first a creation doctrine. After the Lord forms the woman as a helper corresponding to the man, Genesis concludes: “That is why a man leaves his father and mother and is united to his wife, and they become one flesh” (Genesis 2:24). The text presents monogamous, covenantal union as the normative pattern from the beginning, prior to the fall’s distortions (Genesis 3).
Jesus later cites Genesis 1:27 and 2:24 when questioned about divorce (Matthew 19:3–9; Mark 10:2–12). He treats the creation texts as authoritative for marriage’s permanence: “So they are no longer two, but one flesh. Therefore what God has joined together, let no one separate.”
Matthew Henry’s Commentary · Matthew Henry
Henry on Genesis 2 describes marriage as God’s own institution for companionship, mutual help, and the increase of mankind, stressing the “one flesh” union as leaving prior household loyalties to form a new family bond.
Law, wisdom, and faithfulness
The seventh commandment forbids adultery (Exodus 20:14; Deuteronomy 5:18). Wisdom literature celebrates marital fidelity and delight (Proverbs 5:15–19; Song of Solomon) while warning against the adulteress and the destruction that follows unfaithfulness (Proverbs 6:20–35). Malachi rebukes treachery against “the wife of your youth” and names the Lord as witness of the marriage covenant (Malachi 2:14–16).
These strands show marriage as public covenant before God, not merely private affection.
Jamieson-Fausset-Brown Bible Commentary · JFB
JFB on Malachi 2 underline that covenant betrayal in marriage is theological as well as social: the Lord is witness, and faithlessness toward a spouse is faithlessness before God.
Christ and the church: Ephesians 5
Paul’s household instruction in Ephesians 5:21–33 is the New Testament’s densest theology of marriage. Mutual submission “out of reverence for Christ” frames distinct callings: wives are addressed regarding respect and the church’s posture toward Christ; husbands are commanded to love “as Christ loved the church and gave himself up for her,” a cruciform, self-giving standard.
Paul then quotes Genesis 2:24 and adds, “This is a profound mystery, but I am talking about Christ and the church” (Ephesians 5:31–32). The human institution is not erased; it is interpreted as a living parable of the gospel. Parallel texts appear in Colossians 3:18–19 and 1 Peter 3:1–7. Hebrews summarizes the church’s ethic: “Marriage should be honored by all, and the marriage bed kept pure” (Hebrews 13:4).
Paul also honors singleness for undivided devotion to the Lord (1 Corinthians 7), so marriage is highly valued without being made the only faithful Christian calling.
John Gill’s Exposition of the Bible · John Gill
Gill on Ephesians 5 treats the husband’s love as patterned on Christ’s redeeming, sanctifying love for the church, and reads the “mystery” as the typological relation between earthly marriage and the union of Christ with his people.
