1 Corinthians 1:1-9 - Called into the Fellowship of the Son

15 min read

Before Paul names a single Corinthian failure, he names what God has done. God called Paul. God sanctified the Corinthians in Christ. Grace was given, the testimony of Christ was established, gifts were received, and the Church was called into fellowship with the Son. The repeated emphasis is deliberate. Paul will expose pride, faction, sexual sin, contempt at the Lord’s Table, rivalry over gifts, and confusion about resurrection, but he begins with grace because repentance is a return to God’s gift, not an attempt to manufacture holiness through shame.

Acts 18 places this greeting inside a real pastoral history. Paul preached in Corinth, worked beside Aquila and Priscilla, saw people believe and receive Baptism, and remained for a year and six months teaching the word of God.1 Corinth was a Roman colony near the narrow isthmus that joined mainland Greece to the Peloponnese. Its mobility, commerce, public rhetoric, and concern for status help explain pressures that surface later in the letter, but the city should not be caricatured as uniquely depraved.2 Paul addresses a wounded local community as “the church of God.” That name becomes both consolation and summons.

Called and Sanctified in Christ (1 Corinthians 1:1-3)

1 Paul, called to be an apostle of Jesus Christ through the will of God, and Sosthenes our brother,

2 To the church of God which is at Corinth, to those who are sanctified in Christ Jesus, called to be saints, with all who in every place call on the name of Jesus Christ our Lord, both theirs and ours:

3 Grace to you and peace from God our Father and the Lord Jesus Christ.

Paul’s authority begins in a call he did not create. “Called to be an apostle” places his ministry under the will of God before he confronts a church tempted to measure teachers by eloquence, prestige, and personal loyalty. Apostolic authority is real, but it is received authority. Paul therefore cannot boast as the owner of the Church, and the Corinthians cannot use him as the badge of a party.

The address carries the same correction. Paul writes to “the church of God which is at Corinth.” The Church lives in a particular city and bears wounds formed there, yet she belongs to God. Her failures do not make sin harmless, and her failures do not transfer ownership away from Christ. Paul can speak plainly about what must change because he knows whose people they are.

“Sanctified in Christ Jesus” and “called to be saints” are astonishing words for the community described in the rest of the letter. Paul is not declaring every Corinthian spiritually mature. He is naming the consecrated life they received in Christ and must now learn to embody. Holiness is neither an achievement that earns grace nor a title that excuses contradiction. It is God’s gift becoming the shape of worship, sexuality, speech, discipline, service, and love.

Language insight

The Greek binds the opening together through the language of calling. Paul is klētos, a called apostle, in verse 1. The Corinthians are klētois hagiois, called saints or saints by calling, in verse 2. In verse 9, they were called, eklēthēte, into fellowship with the Son. The usual English wording “called to be” is clear, but the Greek does not express an infinitive “to be.” The emphasis falls on God’s summons: apostolic service, the Church’s holy identity, and communion with Christ begin in His initiative and require obedient response.3

The phrase “those who are sanctified” uses a perfect passive form of hagiazō, to sanctify or consecrate. It points to an action received from God whose effect continues. Paul will spend the letter calling their conduct into agreement with that gift. The grammar does not erase their responsibility; it makes responsibility a response to mercy rather than a bid for self-made holiness.4

Gems from the Fathers 💎

Saint John Chrysostom hears Paul’s first word as a cure for boasting. Because Paul is called, the ministry begins with the Caller. Chrysostom writes, “Now here of Him that calleth is everything: of him that is called, nothing, (so to speak,) but only to obey.”5 The parenthetical matters. Grace takes the initiative, while obedience is the human answer.

Chrysostom then reads the Corinthians’ sanctification baptismally: “But what is Sanctification? The Laver, the Purification.”6 “Laver” is his baptismal description of cleansing, not a dictionary definition of the Greek verb. Paul reminds the Corinthians that they have been washed by divine loving-kindness. Remembered rightly, this gives neither pride nor despair. It gives humility, gratitude, and a reason to repent.

Grace and peace complete the greeting. Grace names the divine gift from which the Christian life begins; peace is the reconciled life that gift is meant to form. A community divided around personalities will need both. Paul does not offer peace detached from truth. He gives grace and peace from the Father and the Lord Jesus Christ, then proceeds to bring the Church’s common life under that gift.

Enriched While Waiting for Christ (1 Corinthians 1:4-8)

4 I thank my God always concerning you for the grace of God which was given to you by Christ Jesus, 5 that you were enriched in everything by Him in all utterance and all knowledge, 6 even as the testimony of Christ was confirmed in you, 7 so that you come short in no gift, eagerly waiting for the revelation of our Lord Jesus Christ, 8 who will also confirm you to the end, that you may be blameless in the day of our Lord Jesus Christ.

Paul’s thanksgiving is neither flattery nor a soft introduction to unpleasant subjects. Grace has truly been given to this troubled Church. The Corinthians have truly been enriched in utterance and knowledge. The testimony concerning Christ has truly taken root among them, and their spiritual gifts are real. Paul refuses two easy errors: pretending that gifted people need no correction, and pretending that immature people possess no genuine grace.

Verse 5 says, “you were enriched.” The passive verb keeps the source of their abundance before them. Their speech and knowledge are gifts, not private possessions or proof of superiority. The Greek phrase translated “by Him” can also carry the sense “in Him,” keeping enrichment within union with Christ rather than making it a platform for self-display.7 Later chapters show what happens when speech seeks admiration, knowledge inflates the ego, and gifts become a contest. The answer is not contempt for speech, learning, or charisms. Their proper end is confession of Christ, love of the neighbor, and the building up of His Body.

A sober distinction follows: giftedness is not maturity. A person can speak persuasively, know theology, serve constantly, or exercise a visible gift while envy, resentment, appetite, and the need for recognition remain unhealed. The passage does not license suspicion toward every gifted servant. It forbids us from using usefulness as a substitute for repentance. Grace gives the gift; grace must also govern the heart that carries it.

Paul then turns their gaze forward. They “come short in no gift” while “eagerly waiting for the revelation of our Lord Jesus Christ.” A gifted Church is still an unfinished Church. Gifts are provisions for faithfulness while Christ is awaited, not trophies that make His coming unnecessary. His “revelation” is an unveiling. Christian expectation is therefore neither date speculation nor passive escape. It is the daily ordering of speech, desire, work, worship, and relationships toward the Lord who will appear.

Language insight

Verses 6 and 8 repeat the same Greek root, bebaioō. The testimony of Christ “was confirmed” among the Corinthians, and Christ “will also confirm” them to the end. The Gospel established among them becomes the ground of Christ’s promise to establish His people.8 Paul anchors hope in Christ’s faithfulness, yet the word “blameless” does not mean that their present conduct is sinless. It points toward standing without a charge in the day of the Lord. The promise draws them into perseverance and correction; it does not make either unnecessary.

Chrysostom catches this double edge. He explains that the promise consoles them while its wording also reveals their condition: “To say, ‘He shall confirm,’ and the word ‘unreprovable’ marks them out as still wavering, and liable to reproof.”9 Paul does not choose between assurance and repentance. Christ’s sustaining grace makes honest repentance possible, while the coming day keeps grace from being turned into presumption.

For the Christian who fears that weakness has placed holiness beyond reach, these verses offer firm consolation: Christ is able to sustain His people to the end. For the Christian who points to ministry, knowledge, or spiritual experiences to resist correction, the same verses issue a warning: every gift must be carried toward the day of Christ. God’s faithfulness comforts the humbled and unsettles the complacent.

Called into Fellowship with the Son (1 Corinthians 1:9)

9 God is faithful, by whom you were called into the fellowship of His Son, Jesus Christ our Lord.

Paul reaches the foundation beneath every earlier statement: “God is faithful.” The Church’s future does not rest on Corinthian steadiness. The faithful God who called, sanctified, enriched, and established the testimony will remain true to His work. This is why Paul can correct without despair. He is not trying to create a Church from nothing; he is serving the faithful God who is healing His Church.

The goal of that call is “the fellowship of His Son.” The Greek koinōnia can mean fellowship, communion, sharing, or participation.10 Paul means more than friendliness, social belonging, or attendance at Christian gatherings. The Corinthians have been summoned to share their life in relation to the Son. Later in the letter Paul will use the same word for communion in Christ’s Blood and Body in 1 Corinthians 10:16. The single noun in verse 9 should not be forced to carry the letter’s entire sacramental theology, but the letter itself reveals how deep this fellowship becomes: union with Christ creates communion among those who belong to Him.

This final sentence also prepares the rebuke that follows. A Church called into communion with the one Son cannot build its identity around possessive allegiance to Paul, Apollos, Cephas, or any other servant. Gratitude for a faithful teacher is good. Turning that teacher into a reason for rivalry contradicts the fellowship God has given.

Chrysostom places the contradiction in one sharp sentence: “Into the fellowship of the Only-Begotten have ye been called, and do ye addict yourselves unto men?”11 His older wording means attaching oneself possessively to human leaders. The cure for faction is not disdain for apostles, priests, teachers, or servants. It is the right ordering of love: every true servant belongs under Christ, and every gift of ministry must lead the Church more deeply into communion with Him.

The Coptic lectionary receives these verses within larger Pauline readings. On Epiphany Paramoune, Tubah 10, the reading extends through 1 Corinthians 1:17; on the Fourth Sunday of Amshir, it extends through 1 Corinthians 1:16.12 The passage is therefore heard liturgically together with Paul’s attack on division and boasting. The placements are established, but the available lectionary evidence does not give a detailed explanation for why these readings were appointed. The safe spiritual connection is the one the text itself supplies: a Church preparing to meet Christ must remember who called her, from whom her gifts came, and into whose fellowship she has been brought.

Spiritual Fruit 🍇

Receive correction from inside grace. Some people meet correction with immediate self-defense; others collapse into the thought that failure has erased every good thing God has done. Paul permits neither response. When a sin is exposed, begin where he begins: “I belong to God, I have received grace in Christ, and this wound must now be brought into the light.” In confession or private prayer, name one concrete contradiction between your calling and your conduct without excusing it and without declaring yourself beyond mercy.

Keep real gifts open to correction. Paul thanks God for the Corinthians’ utterance, knowledge, and gifts, then points them toward Christ’s revelation and day. A genuine gift can serve the Church while the person carrying it still needs repentance and formation. When correction exposes pride, impatience, control, careless speech, or harm in the way you use an ability, do not answer by listing how useful the gift has been. Receive the correction as part of learning to carry grace faithfully while the Church waits for Christ. Name what must change, make one concrete repair, and offer the gift again for the building up of His Body.

Let expectation of Christ order the present day. The Corinthians possess gifts while waiting for Christ’s unveiling. That waiting becomes practical whenever the coming day changes a present choice. Before a difficult conversation, ask whether your words could be carried into the presence of Christ. Before using knowledge to win, ask whether it builds His Body. Before postponing reconciliation, remember that the Lord we await is also the Judge who calls His people toward blamelessness.

Rest in God’s faithfulness without turning it into presumption. Fear says that perseverance depends entirely on your strength; presumption says that your response no longer matters. Verse 9 breaks both lies. God is faithful, so pray, repent, and endure with hope. When you fall, return quickly instead of hiding. When you stand, give thanks instead of boasting. The same grace that consoles you also teaches you to obey.

Let fellowship with the Son correct possessive belonging. The koinōnia of verse 9 names communion with Christ before Paul names division in verses 10-17. The heart becomes factional when gratitude for a servant or community hardens into an identity that makes another Christian’s gift feel threatening. When that reaction surfaces, refuse comparison, thank God for the good you received, and remember that the Church and every faithful ministry belong to Christ. Communion with one Son trains us to honor His servants without building our identity around them.
