What does 1 Corinthians 1:2 mean?
Paul's letters follow the general standard for introductions used in his era. He identified himself in the previous verse. Now he describes who the letter is for, adding to that some beautiful theology about all of us who are Christians.Paul is writing to God's church in Corinth. Corinth was a big city on a major trade route. Paul had introduced Christianity and planted a church there, staying for over a year and half to serve the people (Acts 18:1–18). He knew these Corinthians and their environment well.
Paul says he is writing to Christians, those who are sanctified in Christ Jesus. The word "sanctified" refers to something that has been "set apart" for special purposes. Every person who is a Christian has been marked by God, as His own possession, set apart from the rest of humanity for His own purposes. Christians are not hoping, by good behavior, to become sanctified someday. By God's grace through faith in Christ, that has already happened.
Paul next says these Christians in the church in Corinth are called to be saints, together with all the other Christians—those who call on Jesus' name—in all the other places in the world. Theologians sometimes call this group of all the saved people everywhere the "universal church."
Paul writes that one thing we all have in common is that Christ is our Lord. This is true for every Christian.
First Corinthians 1:1–3 follows Paul's normal pattern in the greeting for this letter to the Corinthians. He identifies himself and Sosthenes, who is with him in Ephesus. His recipient is God's church in Corinth. He describes his readers as those who are sanctified—set apart for a special purpose—in Christ Jesus. They are called to be saints with all Christians everywhere. Paul offers them grace and peace from God the Father and from Christ.
Paul's letter to the Christians in Corinth begins with thanks for the great and powerful gifts God has given to them by His grace and through their faith in Christ. They will stand blameless before God in the end. Right now, though, they must stop dividing themselves according to which Christian teacher they follow and become unified in and around Christ. The gospel message of Christ's death on the cross is weak and foolish to the world, but God has given faith in Christ to those who believe it and find God's power and wisdom.
