Ephesians 5:31 describes marriage as a deliberate new beginning: a man leaves the family he grew up in and binds himself to his wife, so that the two form one united life. Paul is not writing a wedding ceremony or a legal code here. He quotes a line from Genesis 2:24 and uses it to explain how Christ loves the church, with marriage as the picture. The words come from Paul, who wrote this letter to the Christians in Ephesus.
“For this cause a man will leave his father and mother, and will be joined to his wife. The two will become one flesh.”

What Ephesians 5:31 Means
“For this cause” points back to the verses just before it, where Paul says that a husband should love his wife as his own body and that the church is a living body joined to Christ. Marriage is the reason the man’s loyalties shift. The verse describes a pattern: a grown man chooses a wife and makes a home with her, which puts the marriage bond ahead of the bonds of his birth family.
“Leave his father and mother” does not mean cutting off relationships or ignoring parents. It means the primary commitment moves. Decisions, loyalty and daily life now run through the marriage. “Joined to his wife” speaks of a firm attachment, like glue or a strong cord. “The two will become one flesh” describes a real and lasting union that touches body, household, finances and purpose. The verse promises nothing about how easy this will feel; it describes what marriage is meant to be.
The Context of Ephesians 5:31
Ephesians was written by Paul to churches in and around the city of Ephesus, a major port city in western Asia Minor. Its readers were mostly Gentile believers who had recently come into the church and needed to understand how their new life in Christ shapes ordinary relationships. Chapter 5 gives practical instructions for households, and the household codes that follow (husbands and wives, children and parents, masters and servants) are all grounded in the believer’s walk in Christ.
Verse 31 sits inside a passage where Paul asks husbands to love their wives the way Christ loves the church, giving himself for her. Verse 32 then says the marriage union is “a great mystery” that points to Christ and the church. Reading the verse in that setting shows that the one-flesh bond is not the main subject. It is an illustration of a deeper union, and it is also a standard for how husbands and wives treat each other.

A Short Prayer From Ephesians 5:31
Lord, thank you for the gift of marriage and for the bond you design between a husband and a wife. Help us to honor the commitments we have made, to put each other first in the choices we face, and to keep our hearts open to one another. Where we have allowed other loyalties to crowd in, show us gently what needs to change. Make our home a place where your love is seen, and let our life together point to the faithfulness of Christ. Amen.
