1 Corinthians 1:1-3

The church's identity and unity begin with God's calling through Christ, not human status or allegiance.

The church exists because of God's calling in Christ and lives under the authority, grace, and peace that come from God the Father and the Lord Jesus Christ.

1. 1:1-3 Paul opens with apostolic authority and addresses the Corinthians as sanctified in Christ Jesus, called saints, and part of the wider people of God who call on the name of the Lord Jesus Christ.
2. 1:4-9 He thanks God for grace already given to them, acknowledges their enrichment in speech and knowledge, affirms that they lack no gift, and anchors their future perseverance in the faithfulness of God.
3. 1:10-17 Paul confronts divisions, rebukes party spirit, and insists that Christ is not divided. He exposes the absurdity of attaching covenant identity to human leaders rather than to the crucified Lord.
4. 1:18-25 Paul contrasts the word of the cross with worldly wisdom. What appears foolish to the perishing is the saving power of God to those being saved. Christ crucified overturns Jewish sign-seeking and Greek wisdom-seeking.
5. 1:26-31 Paul points to the Corinthians’ own calling as evidence that God shames human pride by choosing the weak and lowly. Christ Himself becomes wisdom, righteousness, sanctification, and redemption for believers, so boasting is excluded except in the Lord.

• Paul's claim to apostleship should not be interpreted as self-appointed authority but as a calling rooted in God's will.
• Being sanctified in Christ does not imply moral perfection but a positional identity that calls believers to holy living.
• The phrase 'church of God' prevents the congregation from being viewed as belonging to personalities or factions.
• The greeting should not be dismissed as mere formality; it establishes the theological foundation for the entire letter.
• Grace and peace are not generic greetings but gospel realities grounded in God's saving work in Christ.
• Do not treat Paul's greeting as empty formality, it introduces the theological logic of the whole letter.
• Do not use 'called to be holy' as if holiness is self-generated moralism detached from being sanctified in Christ.
• Do not read apostolic authority here as personality-driven power, Paul roots it in God's will rather than self-promotion.
• Do not reduce the church to a merely local social club, Paul addresses Corinth as part of the wider people who belong to Christ everywhere.
• Do not separate grace and peace from the person and saving work of Jesus Christ.

• Church correction must begin with gospel identity before addressing practical disorder.
• Leaders must remember that authority in the church is derivative and accountable to the will of God and the lordship of Christ.
• Local churches are never isolated enclaves, they belong to the wider people of God who call on Christ's name.
• Holiness is not a later optional upgrade, it is bound up with the church's calling from the outset.
• Grace and peace are not sentimental greetings, they are covenant realities that sustain troubled congregations.

• Covenant Significance : The chapter presents the church as the sanctified covenant people of God in Christ, called into fellowship with His Son and marked by belonging to His name rather than to human mediators. Baptismal and ecclesial identity are implicitly tied to Christ’s redemptive work, not to apostolic personalities. God’s covenant pattern of humbling human pride and claiming a people for Himself continues in the calling of the Corinthians.
