Leviticus 20:11 and NT views on sexual sin?
How does Leviticus 20:11 connect with New Testament teachings on sexual sin?

Leviticus 20:11 at a Glance

• “If a man lies with his father’s wife, he has uncovered his father’s nakedness; both of them must surely be put to death. Their blood is upon them.” (Leviticus 20:11)

• The offense: sexual relations within the father’s marriage bond—an act of incest and adultery.

• The penalty: death, underscoring how grievous the sin is in God’s sight.


The Moral Principle Behind the Penalty

• God defends the purity of marriage (Genesis 2:24).

• Violating the one-flesh union destroys family order and defiles the covenant community (Leviticus 18:6-8).

• Though the civil penalty applied to Israel’s theocracy, the moral principle—sexual purity and respect for marriage—remains timeless.


Echoes in the New Testament

1 Corinthians 5:1-5

• “It is actually reported that there is sexual immorality among you, and of a kind that even pagans do not tolerate: A man has his father’s wife.” (v. 1)

• Paul cites a case identical to Leviticus 20:11, confirming the sin is still condemned under the New Covenant.

• Instead of capital punishment, the church administers discipline: “hand this man over to Satan for the destruction of the flesh” (v. 5)—removal from fellowship so he might repent.

Galatians 5:19-21

• “The works of the flesh are obvious: sexual immorality, impurity, and debauchery … those who practice such things will not inherit the kingdom of God.”

• Sexual sin, including incestuous adultery, bars unrepentant offenders from the kingdom, showing eternal stakes rather than civil penalties.

Hebrews 13:4

• “Marriage must be honored by all and the marriage bed kept undefiled, for God will judge the sexually immoral and adulterers.”

• Judgment remains certain, even if the form differs from Leviticus.

1 Thessalonians 4:3-5

• “For this is the will of God, your sanctification: that you abstain from sexual immorality … not in lustful passion like the pagans who do not know God.”

• The call to holiness reaffirms Leviticus’s demand for purity.


Christ’s Fulfillment and Continued Call to Purity

• Christ bore the law’s condemnation (Romans 8:3-4), so the death penalty is not enforced by the church state.

• Yet He raises the moral bar: lust itself violates the command (Matthew 5:27-28).

• Grace empowers purity: “But you were washed … justified in the name of the Lord Jesus” (1 Corinthians 6:11).


Practical Takeaways for Believers Today

• Treat every sexual relationship outside God-ordained marriage as spiritually deadly.

• Honor family boundaries; incest is still abhorrent to God.

• Pursue church accountability—discipline aims at restoration, not revenge.

• Rely on the Holy Spirit to “put to death the deeds of the body” (Romans 8:13).

• Celebrate Christ’s redemption that removes guilt yet calls us to walk in holiness.
