1 Corinthians 6:18-20

1Co 6:18 Escape from sexual sin. Every sin a person commits is outside the body, but the one committing sexual sin is actually bringing sin into his body.

1Co 6:19 Or do you not yet get it — the fact that your body is a temple housing the Holy Spirit inside you, which you all have been given from God, so you do not belong to yourselves?

1Co 6:20 You all were bought at a price, so bring glory to God with that body of yours.

singular body – plural you

Paul’s language in this section becomes especially delicate because the grammar of the passage carries a theological weight that is easy to miss in English. Every pronoun in verses 19–20 is plural. Paul is not speaking to individual Christians about their individual bodies. He is addressing the entire Corinthian fellowship as though they share one collective body. His concern is not merely personal morality but the purity of the whole community. The church, taken together, is the dwelling place of the Holy Spirit, and therefore the church, as a unified body, must remain faithful.

This matters because the Corinthians were treating sexual sin as a private matter—something one believer might do without affecting anyone else. Paul rejects that assumption. Sexual sin is not an isolated act. It fractures the unity of the body of Christ. When one member joins himself to a prostitute, the entire fellowship is implicated because the entire fellowship is spiritually joined to Christ. The sin of one becomes a wound in the whole. Paul’s plural pronouns underline this reality: the body that must remain pure is the shared body of believers, not merely the physical body of an individual.

Paul’s goal is to help the Corinthians see that their unity with Christ is not abstract or symbolic. It is a real spiritual union that binds them together as one people. Because of that, the temptation to porneia is not simply a personal struggle; it is a threat to the integrity of the whole church. The Spirit dwells within the community, and the community must therefore guard its holiness together. Faithfulness is a shared responsibility. Purity is a communal calling.

Paul’s argument is not meant to shame but to awaken. The Corinthians had been influenced by a worldview that separated spiritual identity from physical behavior. Paul counters that by reminding them that the Spirit inhabits the entire fellowship. What one member does with the body affects the whole body. What one member joins himself to, the whole body is dragged into. Therefore, the entire community must flee sexual sin—not only for individual well‑being but for the honor of the Spirit who dwells among them.

Paul’s plural pronouns preserve this truth: the church is one body, and that one body must remain faithful.

LORD, show us how to keep the whole body pure, so that our purity will give you glory.
