Leviticus 18:22 and NT sexual morality?
How does Leviticus 18:22 connect with New Testament teachings on sexual morality?

Setting the Old Testament Foundation

Leviticus 18:22: “You shall not lie with a man as with a woman; that is an abomination.”

• Placed in a chapter that repeatedly says, “I am the LORD,” underscoring God’s authority.

• Surrounded by prohibitions of incest, adultery, and bestiality—sexual sins viewed as universally sinful, not merely ceremonial.

• The term “abomination” (Hebrew toʿevah) in this moral context signals an enduring ethical standard.


Moral Law Carried into the New Covenant

• The civil and ceremonial aspects of the Mosaic Law met their fulfillment in Christ (Colossians 2:14).

• Yet its moral core is reaffirmed for believers (Romans 13:8-10).

• Leviticus 18:22 sits within that moral core, and the New Testament echoes its substance rather than setting it aside.


Direct NT References to Same-Sex Behavior

Romans 1:26-27:

“Even their women exchanged natural relations for what is unnatural. In the same way the men abandoned natural relations with women and burned with lust for one another.”

1 Corinthians 6:9-11:

“Do not be deceived: neither the sexually immoral… nor men who have sex with men… will inherit the kingdom of God. And that is what some of you were. But you were washed…”

1 Timothy 1:9-11:

“The law is… for the sexually immoral, for men who practice homosexuality…”

• These passages use Greek terms (arsenokoitai, malakoi) drawn from the Leviticus wording (“male” + “bed”), showing deliberate connection.

• Each text treats homosexual practice alongside other sins such as adultery and idolatry, presenting a consistent moral landscape.


Jesus on Sexual Ethics

Matthew 19:4-6:

“‘Haven’t you read,’ He replied, ‘that at the beginning the Creator made them male and female… For this reason a man will leave his father and mother and be joined to his wife…’”

• By rooting sexual ethics in Genesis 1-2, Jesus affirms the male-female design that Leviticus protects.

• He intensifies, rather than relaxes, moral standards (Matthew 5:27-28).


Holiness, Identity, and the Gospel

• Holiness remains the believer’s calling: “It is God’s will that you should be holy: you must abstain from sexual immorality” (1 Thessalonians 4:3-5).

• Grace is equally central: “Such were some of you… but you were justified in the name of the Lord Jesus” (1 Corinthians 6:11).

• Scripture offers hope of transformation without redefining sin.


Walking in Obedience Today

• Guard the heart: Ephesians 5:3—“But among you, as is proper for saints, there must not be even a hint of sexual immorality.”

• Honor marriage: Hebrews 13:4—“Marriage should be honored by all, and the marriage bed kept undefiled.”

• Pursue purity together: Galatians 6:1 calls believers to restore one another gently, upholding truth and extending mercy.
