Leviticus 20:4 vs. Matthew 18:15-17?
What connections exist between Leviticus 20:4 and Matthew 18:15-17 on confronting sin?

Leviticus 20:4—Community Obligation to Address Evil

“ ‘If the people of the land ever close their eyes to that man when he gives one of his children to Molech and fail to put him to death,’ ”

• God charges “the people of the land” with responsibility; silence makes them complicit.

• The sin is public and lethal; ignoring it invites God’s judgment (vv. 5-6).

• Justice requires action, even when confrontation is uncomfortable (cf. Deuteronomy 19:16-19).

• Failure to act offends God before it harms society; holiness begins with obedience (Leviticus 19:2).


Matthew 18:15-17—Jesus’ Pattern for Restoring a Sinning Brother

“ ‘If your brother sins against you, go and confront him privately…’ ” (BSB, abridged)

• Step 1 – Private conversation: aim for repentance and reconciliation.

• Step 2 – Two or three witnesses: protect truth, fulfill Deuteronomy 19:15.

• Step 3 – Tell it to the church: involve the covenant community.

• Final step – Separation: treat the unrepentant as “a pagan or a tax collector,” keeping the body pure (1 Corinthians 5:6-13).


Shared Threads Between the Passages

• Corporate Responsibility

– Leviticus: whole nation must act.

– Matthew: entire church eventually becomes involved.

• Refusal to Confront Equals Participation

– “Close their eyes” (Leviticus 20:4) mirrors ignoring sin in the church (James 4:17).

• Witnesses Safeguard Justice

– Old-Covenant death penalty required witnesses (Deuteronomy 17:6).

– New-Covenant discipline requires “two or three” (Matthew 18:16).

• Gradation of Consequences

– Leviticus: capital punishment after due process.

– Matthew: escalating steps ending in exclusion, not execution, yet still serious.


How Revelation Progresses Yet Principles Remain

• Same holy God: sin endangers covenant life (Hebrews 10:26-31).

• Different covenant administrations: civil penalty under Moses; spiritual discipline under Christ.

• Goal unchanged: protect community and call sinners to repentance (Ezekiel 33:7-9; Galatians 6:1).


Practical Takeaways

• Confrontation is loving, not optional; ignoring sin harms everyone.

• Begin privately, keep matters as small as repentance allows.

• Involve others only when necessary, always aiming at restoration.

• Churches must uphold discipline to honor God’s holiness and display the gospel’s power.

Why is ignoring sin, as mentioned in Leviticus 20:4, dangerous for believers?
