1 Corinthians 1: Called, United, and Boasting in the Lord

Short answer: Paul writes to the church in Corinth, thanking God for their gifts while urging them to be united in mind and judgment. He confronts their divisions over favorite leaders and shows that God saves through the foolish message of the cross, choosing the weak and lowly so no one can boast before him.

What 1 Corinthians 1 says

Paul opens with his calling as an apostle and addresses the assembly in Corinth as those sanctified in Christ and called saints, together with all who call on the name of the Lord everywhere. He speaks grace and peace from God the Father and the Lord Jesus Christ. He then gives thanks for the grace given to them in Christ, noting how they were enriched in all speech and knowledge as the testimony of Christ was confirmed among them. They do not lack any gift as they wait for the revelation of the Lord Jesus, who will confirm them to the end, blameless in the day of the Lord. God is faithful, and it is he who called them into fellowship with his Son.

Paul moves from thanksgiving to a strong appeal. He begs them, through the name of the Lord Jesus Christ, that they all speak the same thing and that there be no divisions among them, but that they be perfected together in the same mind and judgment. He explains that Chloe's household has reported contentions among them. Each one claims loyalty to Paul, Apollos, Cephas, or Christ. Paul asks if Christ is divided, if Paul was crucified for them, or if they were baptized into Paul's name. He is thankful he baptized only Crispus, Gaius, and the household of Stephanas, so no one can say he baptized into his own name. Christ sent him not to baptize but to preach the good news, not with wisdom of words, so the cross would not be made void.

Paul then explains why the message of the cross cannot be dressed up in human eloquence. The word of the cross is foolishness to those who are dying, but to those being saved it is the power of God. He cites the writing that God will destroy the wisdom of the wise and bring the discernment of the discerning to nothing. He asks where the wise, the scribe, and the lawyer of this world are, and declares that God has made foolish the wisdom of this world. Since the world through its wisdom did not know God, it pleased God through the foolishness of preaching to save those who believe. Jews ask for signs and Greeks seek wisdom, but the apostles preach Christ crucified, a stumbling block to Jews and foolishness to Greeks. Yet to those who are called, both Jews and Greeks, Christ is the power of God and the wisdom of God, because the foolishness of God is wiser than men and the weakness of God is stronger than men.

Paul applies this to the Corinthians' own calling. He reminds them that not many were wise according to the flesh, not many mighty, not many noble. But God chose the foolish things of the world to shame the wise, the weak things to shame the strong, and the lowly and despised things, even things that do not exist, to bring to nothing the things that exist. The purpose is that no flesh should boast before God. Because of God, they are in Christ Jesus, who became for them wisdom from God, and righteousness, sanctification, and redemption. The chapter ends with the written word that whoever boasts should boast in the Lord.

Verses that carry the chapter

• “God is faithful, through whom you were called into the fellowship of his Son, Jesus Christ, our Lord.” (1 Corinthians 1:9) — This verse grounds the entire letter in God's faithfulness and the believers' calling into fellowship with his Son, a foundation for the unity Paul will urge.
• “Now I beg you, brothers, through the name of our Lord, Jesus Christ, that you all speak the same thing, and that there be no divisions among you, but that you be perfected together in the same mind and in the same judgment.” (1 Corinthians 1:10) — Here Paul makes his central appeal for unity, asking the church to speak the same thing and be perfected together in the same mind and judgment.
• “For the word of the cross is foolishness to those who are dying, but to us who are being saved it is the power of God.” (1 Corinthians 1:18) — This verse states the paradox that the word of the cross is foolishness to the dying but the power of God to those being saved, setting up the whole argument about wisdom.
• “that, as it is written, “He who boasts, let him boast in the Lord.” (1 Corinthians 1:31)” (1 Corinthians 1:31) — The chapter's conclusion gives the proper response to God's choosing: any boasting must be in the Lord, not in human wisdom, status, or leaders.

Gospel connection

The chapter connects to the wider biblical story by showing that God's saving work has always run counter to human expectations. From the beginning, God has chosen unlikely people and worked through weakness, but here the cross becomes the decisive revelation of that pattern. The message of Christ crucified is not an afterthought; it is the power and wisdom of God for salvation. This fulfills the pattern seen in Israel's history, where God repeatedly chose the least and the overlooked. It also anticipates the final day when Christ will confirm believers blameless, as verse 8 says. The cross is the center of the gospel, and it humbles every claim of human wisdom or status, directing all glory to the Lord.

Application

This chapter asks the reader to examine where their identity and boasting lie. It calls for unity in the church, not around favorite leaders or styles, but around the crucified Christ. It invites believers to stop measuring themselves or others by worldly wisdom, power, or nobility, and to embrace the foolishness of the cross as God's saving power. Practically, this means refusing to divide over personalities, speaking the same thing in love, and finding confidence not in gifts or knowledge but in the Lord. It also means accepting that God often works through what the world considers weak and despised, so no one has grounds to boast except in him.

Biblical fidelity check

The chapter does not claim that Paul founded the church in Corinth, nor does it give details about Chloe, Apollos, Cephas, or the households mentioned beyond their names. It does not say that baptism is unimportant, only that Paul's primary calling was to preach the good news. It does not explain exactly what the contentions were or who started them. It does not claim that wisdom itself is evil, but that the wisdom of this world cannot know God. It does not say that no wise, mighty, or noble person is called, only that not many are. The text is silent on the outcome of the divisions and on the specific false teachings in Corinth.

FAQ

Why does Paul thank God for the Corinthians if he is about to correct them?

Paul begins with genuine gratitude for God's grace at work in them, noting their enrichment in speech and knowledge and God's faithfulness. This thanksgiving prepares the way for his correction, showing that he addresses them as fellow believers.

What does Paul mean when he says the word of the cross is foolishness?

He means that to those who are perishing, the message of a crucified Messiah seems like nonsense. But to those being saved, that same message is the power of God, because God chose to save through what the world considers weak and foolish.

Does this chapter teach that Christians should not seek wisdom or knowledge?

No, it teaches that the wisdom of this world cannot know God and that human wisdom must not become a source of pride or division. Christ himself is made to us wisdom from God, so true wisdom is found in him, not in worldly status or cleverness.
