Marriage is not merely a piece of paper; it is a living picture of Christ’s unbreakable love for His Bride, the Church (Ephesians 5). By guarding the permanence of the marriage bond, the church protects the innocent, honors God’s creation design, and testifies to a watching world about the faithful, covenant-keeping love of God.

Few institutions in the modern world have been as fiercely debated, redefined, and fractured as marriage. Contemporary culture increasingly views marriage as a fluid social contract based on personal fulfillment, to be entered and exited at will.

Against this cultural confusion, the Westminster Confession offers a profoundly stabilizing, biblical theology of the family. In Chapter 24, the divines remind us that marriage is not a human invention to be reimagined, but a divine institution rooted in creation. By establishing a high, biblical view of marriage, the Confession simultaneously establishes strict, biblical boundaries for divorce.

The Confession teaches that marriage is a creation ordinance between one man and one woman designed for mutual help, procreation, and purity; that Christians must only marry fellow believers; and that the marriage bond is permanent, capable of being dissolved only on the explicit biblical grounds of adultery or irremediable desertion.

The Design and Purpose of Marriage (WCF 24.1–24.2)

The Confession begins with the foundational definition of marriage established by Jesus Himself (Matt. 19:4-6 ): “Marriage is to be between one man and one woman.”

Because it is a creation ordinance (established in Genesis 2), its structure is fixed. The Confession explicitly condemns polygamy—”neither is it lawful for any man to have more than one wife, nor for any woman to have more than one husband.” While the Old Testament records instances of polygamy among the patriarchs and kings, this was a tolerated deviation from God’s original, monogamous design.

Why did God create marriage? The divines list three primary purposes:

• Companionship: “For the mutual help of husband and wife.” God said it was not good for man to be alone.
• Procreation: “For the increase of mankind with a legitimate issue, and of the Church with an holy seed.” God desires godly families to fill the earth and pass down the faith.
• Purity: “For preventing of uncleanness.” In a fallen world with powerful sexual desires, marriage provides the sole, God-honoring context for sexual intimacy (1 Cor. 7:2).

Marrying in the Lord (WCF 24.3)

Because marriage is a creation ordinance (given to all humanity, not just the church), “It is lawful for all sorts of people to marry, who are able with judgment to give their consent.” You do not have to be a Christian to have a valid marriage.
