Marriage

Intro

What is marriage actually for? In a world where the word now means many different things, the Christian answer is specific. Marriage is a covenant between one man and one woman, meant for life, that creates a real bodily and emotional union and pictures Christ's love for his church.

Each of those words is doing work. Covenant says marriage is not just a contract you can walk away from. Man and woman says the male-female pairing is part of the design, not a cultural accident. For life says the door is meant to stay shut. One flesh says marriage is more than feelings or paperwork. Pictures Christ and the church says the whole thing has a meaning bigger than the two people inside it.

This view is not universally accepted today, and Christians should not pretend it is. Many people see marriage as a private contract between adults to be defined however the partners wish. Others point to polygamy in the Old Testament and ask how Christians can claim a single, lifelong, one-man-one-woman pattern is the biblical norm. Those questions are taken seriously below.

The Christian case rests mostly on three texts read together. Genesis 2 sets the creation pattern (Gen 2:24). Jesus reaffirms it as still binding (Matt 19:4-6). Paul reads the whole institution as a picture of Christ and the church (Eph 5:22-33). If those readings are right, marriage is something we receive from God, not something we invent for ourselves.

There is a cost to holding this view. It puts a Christian at odds with major streams of the surrounding culture on sexuality, divorce, and the structure of the family. It also makes a high demand on Christian marriages: husbands are commanded to love their wives the way Christ loved the church, "and gave himself up for her." The position is demanding for everyone holding it, not just for those outside it.

Search-landing page for the Christian doctrine of marriage. The biblical and historic-Christian view: marriage is a covenantal, male-female, lifelong, one-flesh union that pictures the relationship between Christ and his Church (Eph 5:22-33). It is instituted at creation (Gen 2:24), reaffirmed by Christ (Matt 19:4-6), and given its ultimate Christological meaning by Paul (Eph 5). It is the only context within which sexual union is morally permissible in biblical ethics.

Christian Position

Covenantal, not contractual, a covenant before God, witnessed publicly, sealed bodily (Mal 2:14: "she is your companion and your wife by covenant").
Male-female, grounded in the creation pattern (Gen 1:27; 2:24) and the complementarity of male and female bearing the imago Dei together; reaffirmed by Christ (Matt 19:4-6) and Paul (Eph 5:31).
Lifelong, "what God has joined together, let no man separate" (Matt 19:6); divorce is a concession to hardness of heart, not the design (see Divorce).
One-flesh, a real bodily, emotional, and spiritual union, not merely a legal arrangement (Gen 2:24; 1 Cor 6:16-17).
Christ-Church type, marriage pictures Christ's covenantal self-giving love for his bride the Church (Eph 5:22-33); this is the deepest theological purpose of marriage in the NT.

Common Objection

The standard objection runs in several forms: (1) the OT shows polygamy practiced by Abraham, Jacob, David, and Solomon, so "biblical marriage" is not actually monogamous; (2) marriage in the ancient world was an economic arrangement, not the romantic-companionate institution Christians claim; (3) the Church's elevation of marriage is anti-woman, since the NT instructs wives to "submit"; (4) confining marriage to male-female is arbitrary cultural prejudice projected back onto creation.

Response

On OT polygamy: described, not prescribed, the polygamy narratives in Genesis-Kings are universally cautionary (Abraham/Hagar produces the Ishmael conflict; Jacob's polygamy fractures the family; Solomon's wives turn his heart from God). The creation pattern (Gen 2:24, one man + one woman) is the norm; polygamy is concession to hardness of heart, similar to divorce. See OT Polygamy Objection for the structured defeater.
On economic arrangement: in fact the biblical pattern elevated the woman's status, Christ's interaction with women, his ban on easy divorce (which protected women from being discarded), and Paul's reciprocal-submission framework (Eph 5:21, then both wife-husband instructions) all push against the surrounding Greco-Roman patriarchal default.
On "submit": Eph 5:22-33 is bracketed by Eph 5:21 (mutual submission) and commands the husband to love his wife as Christ loved the Church and gave himself up for her, the heavier obligation falls on the husband, not the wife.
On male-female arbitrariness: the male-female structure is grounded in the creation pattern, not in cultural prejudice, male and female together bear the image of God (Gen 1:27), and the procreative-and-complementary union has both biological and theological signification. The historic-consensus reading of Christianity, Judaism, and Islam all converge on this for ~3,000+ years; the affirming reading is novel.
