Link 2 Cor 6:17 to OT holiness calls?
How does 2 Corinthians 6:17 connect with Old Testament calls for holiness?

2 Corinthians 6:17—Paul Echoes an Ancient Call

“Therefore, ‘Come out from among them and be separate, says the Lord. Touch no unclean thing, and I will receive you.’”


Direct Line to Isaiah 52:11

Paul is quoting Isaiah’s exodus-style appeal to the returning exiles:

• “Depart, depart, go out from there! Touch no unclean thing! Come out from her, purify yourselves, you who carry the vessels of the LORD.” (Isaiah 52:11)

• Both passages:

– Address God’s people living amid a corrupt culture.

– Command physical and moral separation.

– Tie purity to God’s acceptance and fellowship.


Leviticus—Where the Separation Principle Begins

God established holiness as the family trait of His covenant people:

Leviticus 11:44-45 “Consecrate yourselves…be holy, for I am holy.”

Leviticus 20:26 “I have set you apart from the peoples to be My own.”

Key observations:

1. Holiness is rooted in God’s own character (“for I am holy”).

2. Separation is not isolation but consecration—belonging exclusively to Him.

3. The clean/unclean laws trained Israel to make daily distinctions; Paul applies the same readiness to the Corinthians’ relationships and worship.


Prophetic Reinforcement of the Separation Theme

The prophets continually repeat the Levitical rhythm:

Jeremiah 51:45 “Come out of her, My people!” (from Babylon)

Ezekiel 20:41 “I will accept you…when I bring you out from the peoples.”

Zechariah 2:7 “Come, Zion! Escape, you who dwell with Daughter Babylon!”

These passages promise God’s welcome (“I will receive you”) the moment His people abandon idolatry and impurity.


A Single Thread Through Covenant History

• Exodus—God pulls Israel out of Egypt to be “a kingdom of priests and a holy nation” (Exodus 19:5-6).

• Exile—Isaiah urges another departure from unclean Babylon.

• Church Age—Paul lifts the same words for believers surrounded by paganism.

The unchanging pattern: deliverance ➜ separation ➜ holiness ➜ fellowship with God.


Practical Takeaways for Today

• Guard your heart from partnerships that dull affection for Christ (2 Corinthians 6:14-16).

• Refuse what Scripture defines as “unclean,” whether in entertainment, business, or worship.

• Remember separation is unto Someone: “I will be a Father to you” (2 Corinthians 6:18; cf. 2 Samuel 7:14).

• Pursue holiness not as legalism but as love—imitating the God who first set us apart.


Conclusion—From Sinai to Corinth to Us

2 Corinthians 6:17 is not a new idea; it is the consistent heartbeat of the Bible. The same holy God who spoke at Sinai, pleaded through Isaiah, and thundered through Jeremiah now speaks through Paul: “Come out…and be separate.” Separation remains the doorway into deeper communion with the One who promises, “I will receive you.”
