Leviticus 18:8 vs. 1 Corinthians 5:1?
How does Leviticus 18:8 relate to the situation in 1 Corinthians 5:1?

Setting the Scene

“ ‘You must not have sexual relations with your father’s wife; it would dishonor your father.’ ” (Leviticus 18:8)

“ It is actually reported that there is sexual immorality among you, and of a kind that is intolerable even among pagans: A man has his father’s wife.” (1 Corinthians 5:1)


Leviticus 18:8—A Clear Boundary

• God speaks directly, placing an unequivocal fence around the step-parent relationship.

• The sin is labeled “dishonor”—not merely a private failing, but a public disgrace against the father, the family, and the covenant community.

• The broader context of Leviticus 18 lists forbidden unions that defile the land (vv. 24-30), underlining that this command is moral, not ceremonial.


1 Corinthians 5:1—A Startling Breach

• Paul identifies the exact violation Leviticus forbids: “A man has his father’s wife.”

• Shock factor: even the surrounding pagan culture recoiled, yet the church tolerated it (v. 2).

• Paul’s strong language (“intolerable”) shows that Scripture’s moral boundaries remain intact under the New Covenant.


Why Paul Echoes Leviticus

• Same God, same standard—Paul assumes his readers know the Torah’s prohibition.

• By citing the community’s horror, Paul highlights how Scripture’s authority should have pre-empted any debate.

• The apostle applies Leviticus to:

– Preserve the church’s purity (vv. 6-8).

– Protect the offender’s soul through discipline (v. 5).

– Guard the testimony of Christ in a watching world (v. 1).


Other Passages Reinforcing the Link

Deuteronomy 27:20—“Cursed is he who lies with his father’s wife, because he has uncovered his father’s skirt.”

Deuteronomy 22:30—“A man is not to marry his father’s wife; he must not dishonor his father’s bed.”

Hebrews 13:4—“Marriage must be honored by all and the marriage bed kept undefiled.”

1 Timothy 5:20—Public sin, when left unchecked, harms the whole body.

2 Corinthians 2:6-8—After repentance, restoration is urged, showing discipline’s redemptive goal.


Timeless Takeaways

• God’s moral boundaries do not shift with culture; they arise from His unchanging character.

• Tolerating known sin harms both the sinner and the church’s witness.

• Loving discipline, rooted in Scripture, aims at repentance and restoration.
