Ephesians 5:31 on biblical marriage?
How does Ephesians 5:31 define the concept of marriage in a biblical context?

Text and Immediate Context

Ephesians 5:31 : “For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh.”

Paul cites Genesis 2:24 verbatim to ground his teaching in God’s original design. Verses 22-33 frame marriage as an enacted parable of Christ’s union with the church, so v. 31 is the pivot linking Eden to Calvary.


Old Testament Foundation

Genesis 2:24 presents marriage before the Fall, within a literal creation week (≈ 4000 BC on a Usshurian chronology). The Hebrew verbs “ʿāzab” (leave) and “dābaq” (cleave) depict a decisive, lifelong bond. Malachi 2:14 calls this bond a “covenant,” underscoring permanence and divine witness.


One-Flesh Union

“One flesh” (Heb ’ekhād bâśār; Gk sárx mía) speaks to:

a) physical consummation,

b) economic/social unity,

c) spiritual solidarity.

Jesus in Matthew 19:6 adds, “What therefore God has joined together, let not man separate,” sealing the union’s indissolubility.


Covenant, Not Contract

Biblically, marriage is a tri-party covenant (husband-wife-God). Proverbs 2:17 rebukes one “who forgets the covenant of her God.” Covenantal language penetrates both Testaments (cf. Ezekiel 16; Hosea 2), situating marriage within God’s own faithfulness.


Complementarity of Male and Female

Creation presents distinct yet complementary sexes (Genesis 1:27). Intelligent-design scholarship highlights irreducible complexity in human reproductive systems; they function only as a coordinated pair, matching the biblical claim that the two become one entity.


Headship and Mutuality

Ephesians 5:23–30 assigns the husband sacrificial headship (“love your wives, just as Christ loved the church,” v. 25) and the wife respectful submission (v. 22). This is neither authoritarianism nor egalitarian flattening but patterned after Trinitarian harmony—equality of worth, diversity of roles.


Exclusivity and Permanence

“To leave … be united” establishes a new primary loyalty, superseding parental bonds. The singular terms “man … wife” indicate monogamy; Jesus validates this by opposing polygamy’s drift in first-century culture (Mark 10:5-9).


Procreation and Stewardship

While marriage is more than childbearing, Genesis 1:28 couples the union with “be fruitful and multiply.” Modern genetics shows children inherit a blended genome—literal “one flesh.” God entrusts parents to disciple offspring (Deuteronomy 6:6-7).


Sanctity and Sexual Purity

Hebrews 13:4 commands: “Marriage should be honored by all, and the marriage bed kept undefiled.” The one-flesh bond restricts sexual activity to the covenant pair, excluding adultery, fornication, and homosexual practice (1 Corinthians 6:9-20).


Christ-Church Mystery

Paul calls v. 31 a “mystery” (Ephesians 5:32): earthly marriage images Christ (bridegroom) and the redeemed (bride). Thus, attacking marriage distorts gospel optics; honoring marriage proclaims resurrection love.


Historical and Archaeological Corroboration

First-century Jewish marriage contracts from the Judean Desert (e.g., Babatha archive, AD 93-132) echo covenant language paralleling Genesis 2:24. Early Christian writers (Ignatius, Polycarp) quote the verse, evidencing continuous interpretation.


Ethical and Societal Implications

Ephesians 5:31 frames marriage as foundational to societal stability. When civil law mirrors this definition, cultures reap measurable benefits—lower crime, higher generational transfer of faith values.


Summary

Ephesians 5:31 defines marriage as a divinely instituted, lifelong, exclusive, covenantal union between one man and one woman, forging a holistic one-flesh bond that images Christ’s redemptive love and anchors human flourishing.
