1 From Paul, called to be an apostle of Christ Jesus by the will of God, and Sosthenes, our brother,2 to the church of God that is in Corinth, to those who are sanctified in Christ Jesus, and called to be saints, with all those in every place who call on the name of our Lord Jesus Christ, their Lord and ours.3 Grace and peace to you from God our Father and the Lord Jesus Christ!4 I always thank my God for you because of the grace of God that was given to you in Christ Jesus.5 For you were made rich in every way in him, in all your speech and in every kind of knowledge -6 just as the testimony about Christ has been confirmed among you-7 so that you do not lack any spiritual gift as you wait for the revelation of our Lord Jesus Christ.8 He will also strengthen you to the end, so that you will be blameless on the day of our Lord Jesus Christ.9 God is faithful, by whom you were called into fellowship with his son, Jesus Christ our Lord.
- Paul immediately establishes his apostolic authority, grounding it in God's will, not human appointment (1 Cor 1:1).
- Sosthenes, possibly the former synagogue ruler mentioned in Acts 18:17, is co-sender, indicating his standing in the church.
- The letter is addressed to the "church of God in Corinth," reminding them of their divine identity despite their internal problems (1 Cor 1:2).
- Believers are described as "sanctified in Christ Jesus" (positional holiness) and "called to be holy" (practical living) (1 Cor 1:2).
- The greeting extends to "all those everywhere," highlighting the universality of the church and Christ's lordship (1 Cor 1:2).
- The standard Pauline greeting "Grace and peace" combines Greek and Hebrew salutations, rooted in God and Christ (1 Cor 1:3).
- Paul's thanksgiving focuses on God's grace already given to the Corinthians, particularly their giftedness in speech and knowledge (1 Cor 1:4-5) – areas later shown to be sources of pride and division.
- These gifts served as confirmation ("testimony... confirmed") of the gospel message they received (1 Cor 1:6).
- Paul affirms they lack no spiritual gift while awaiting Christ's return, setting a high standard against which their behavior will be measured (1 Cor 1:7).
- Assurance is given that God, through Christ, will sustain them blameless until the final judgment ("the day of our Lord Jesus Christ") (1 Cor 1:8).
- The foundation for this assurance is God's faithfulness, who initiated their relationship ("called into fellowship" - Greek *koinonia*) with Christ (1 Cor 1:9).
