1 Corinthians 6:15-16 — “Shall I then take the members of Christ and unite them with a prostitute? Never!”

Key Parallels to Deuteronomy 23:17

• Both Testaments forbid any form of prostitution or cultic sexuality.

• Sexual immorality is repeatedly tied to idolatry—body worship replaced worship of God.

• God claims ownership of His people’s bodies; misuse of the body profanes what is holy.

• Judgment is promised on persistent, unrepentant immorality, while purity marks covenant faithfulness.


Living Out the Consistent Biblical Standard

• Flee, don’t flirt, with sexual sin (1 Corinthians 6:18).

• Treat your body as God’s temple (1 Corinthians 6:19).

• Honor marriage and keep sexual expression inside that covenant (Hebrews 13:4).

• Guard your heart and mind, where impurity starts (Mark 7:21-23; Matthew 5:28).
