1 Corinthians 6:17 · KJV

Holy Spirit

Context

15

Know ye not that your bodies are the members of Christ? shall I then take the members of Christ, and make them the members of an harlot? God forbid .

16

What? know ye not that he which is joined to an harlot is one body? for two, saith he, shall be one flesh.

17

But he that is joined unto the Lord is one spirit.

18

Flee fornication. Every sin that a man doeth is without the body; but he that committeth fornication sinneth against his own body.

19

What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own?

Commentary

KJV Study Commentary
But he that is joined unto the Lord is one spirit. The contrast to verse 16: ho de kollamenos tō kyriō hen pneuma estin (ὁ δὲ κολλώμενος τῷ κυρίῳ ἓν πνεῦμα ἐστίν). Kollaō (κολλάω) again—'joined, united'—but now to the Lord (tō kyriō), resulting in one spirit (hen pneuma, ἓν πνεῦμα). While sexual union creates one-flesh entity, union with Christ creates one-spirit entity.

This doesn't disparage bodies (Paul just emphasized their importance!) but highlights the spiritual dimension of salvation: the Holy Spirit unites believers to Christ (Romans 8:9-11). Pneuma here is likely the shared Spirit—Christ's Spirit indwelling believers (Galatians 2:20). Paul's argument: you can't be one-spirit with Christ and one-flesh with a prostitute simultaneously. Competing unions fracture identity. Loyalty to Christ requires sexual fidelity.

Historical & Cultural Context

Mystical union language permeates Paul (Galatians 2:20, Philippians 1:21, Colossians 3:3). This isn't abstract doctrine but lived reality: the Spirit's presence reorients desires, identity, ethics. Corinthians pursued pneumatic experiences (tongues, prophecy) while tolerating porneia—Paul says: the Spirit who unites you to Christ demands holiness, not just charismatic manifestations. True spirituality is cruciform, not just ecstatic. Union with Christ reshapes sexuality, finances (vv. 1-8), and all behavior.

Reflection Questions

  1. How does being 'one spirit' with Christ inform your identity more fundamentally than any other relationship or experience?
  2. What competing 'unions' or loyalties (addictions, relationships, ambitions) fracture your singular devotion to Christ?
  3. How can you cultivate awareness of the Spirit's indwelling presence as motivation for sexual purity?
