Contrast Deut 13:15 & 1 Cor 5:13 on sin.
Compare Deuteronomy 13:15 with 1 Corinthians 5:13 on dealing with sin.

Two Texts, One Holy Purpose

Deuteronomy 13:15—“you must surely strike the inhabitants of that city with the sword. Destroy it completely, all that is in it, and its livestock with the edge of the sword.”

1 Corinthians 5:13—“God will judge those outside. ‘Expel the wicked man from among you.’”


What’s Happening in Deuteronomy 13

• Old-covenant Israel is a theocratic nation; idolatry is treason against the Lord who rescued them (Exodus 20:2–3).

• The command is civil and corporate: the whole city must be destroyed if it has turned to other gods.

• Capital punishment underscores the absolute holiness of God (Leviticus 20:2–3).

• The aim: purge evil so that covenant blessing continues (Deuteronomy 13:17).


What’s Happening in 1 Corinthians 5

• New-covenant believers form a spiritual body, not a political state (Philippians 3:20).

• The sin is flagrant sexual immorality that the church has tolerated.

• Discipline is ecclesiastical, not civil: remove fellowship, not take life (Matthew 18:15-17).

• Goal: protect the church’s purity, provoke repentance, and display God’s holiness (Galatians 6:1; 2 Corinthians 7:10).


Shared Themes That Never Change

• God’s holiness demands decisive action against persistent, public sin.

• The community bears responsibility to act, not merely the individual.

• Removing evil protects the wider body from contagion (1 Corinthians 5:6; Joshua 7).


Key Covenant Differences

" Old Covenant (Israel) " New Covenant (Church) "

" — " — "

" Nation under divine law " Spiritual family within many nations "

" Civil sword by state authority " Spiritual authority by church elders "

" Death of the impenitent " Exclusion and restoration aim "

" Typifies final judgment " Foreshadows eternal separation "


Consistent Principles for Today

• Treat sin seriously; delay invites deeper damage (James 1:15).

• Follow God-given procedures—evidence, witnesses, due process (Deuteronomy 13:14; 2 Corinthians 13:1).

• Exercise discipline with humility and love, seeking restoration (Galatians 6:1-2).

• Trust God’s final judgment; the church enforces purity, not vengeance (Romans 12:19).


Practical Steps for a Local Church

1. Investigate credibly reported sin promptly and fairly.

2. Confront privately first; widen the circle only if unrepentant (Matthew 18:15-17).

3. If stubborn rebellion persists, announce removal from membership and the Table (1 Corinthians 5:11).

4. Maintain hopeful contact, urging repentance (2 Thessalonians 3:14-15).

5. Rejoice in restoration when repentance appears (2 Corinthians 2:6-8).


Why It Matters

• Holiness safeguards gospel witness (1 Peter 2:12).

• Loving discipline displays God’s character—just and merciful (Hebrews 12:10-11).

• Obedience invites blessing and unity (Psalm 133; John 15:10-11).
