Paul’s opening words in 1 Corinthians 1:1–3 establish that the letter’s authority belongs to God, not to its human author. Paul identifies his apostleship as divinely called, not self-appointed, echoing Galatians 1:1 and Romans 1:1. He addresses believers already “sanctified in Christ Jesus,” meaning set apart by God’s declaration, not personal effort. His greeting—”grace and peace”—compresses the gospel into two words drawn from both Greek and Hebrew tradition. Those who explore further will find each phrase carrying more weight than it first appears.
God Called Paul to Write This: The Corinthians Didn’t Choose Him
When Paul wrote to the church at Corinth, the circumstances of the letter’s origin mattered from the very first line. Paul identified himself as “called” by God’s will, not appointed by the congregation. The Corinthians received the letter; they did not commission it.
This distinction carried real weight, because the church was already divided over which leaders to follow. Factions had formed around different figures, making apostolic authority a genuine tension.
Paul’s opening settled one question clearly: his instruction arrived through divine appointment, not personal ambition or congregational preference, and the church was expected to receive it accordingly. His co-sender, Sosthenes, was identified simply as a brother, grounding the letter in shared faith rather than competing credentials. Across multiple translations, Paul’s role is rendered with titles ranging from “apostle” to “emissary” to “messenger,” but the calling itself remains consistent—he was sent by divine will, not self-appointed. The Bible also affirms the legitimacy of governing authorities, which helps situate apostolic instruction within public life.
Paul’s Apostleship Was God’s Idea, Not His Own
Before Paul wrote a single letter or preached a single sermon, the question of where his authority came from was already answered.
Galatians 1:1 records his own claim plainly: his apostleship came “through Jesus Christ and God the Father, not from men nor through man.”
Paul did not appoint himself. His authority came through Jesus Christ and God the Father alone.
Romans 1:1 calls him “called to be an apostle,” linking the role to divine summons rather than personal ambition.
Acts 9 confirms this with the Damascus road encounter, where the risen Jesus commissions him directly.
Paul’s apostleship, then, was not his idea.
It was God’s appointment, extended by grace to an unlikely recipient. Notably, Paul was not one of the Twelve Apostles, yet he is regarded as one of the most important figures of the entire Apostolic Age.
Paul introduces himself as an apostle in nine of thirteen letters, a consistency that signals how foundational this identity was to everything he wrote and taught.
This understanding of apostolic authority also shaped how early Christians wrestled with issues like body markings and conscience in light of Scripture and culture.
What “Sanctified in Christ” Actually Means in 1 Corinthians 1:2
God’s appointment of Paul as an apostle was not the only declaration made at the opening of 1 Corinthians.
Paul also described the Corinthian believers as “sanctified in Christ Jesus.”
The Greek root means “set apart,” and the past tense indicates this already happened—it was not a future goal.
Scholars note this is positional sanctification, meaning God declared believers holy based on their union with Christ, not personal merit.
The entire congregation shared this status equally.
Yet this declared holiness also carried a forward-facing dimension, calling believers to live in practical conformity with the identity God had already granted them.
Paul extended this identity beyond Corinth, addressing the letter together with all who everywhere call on the name of our Lord Jesus Christ, grounding global Christian unity in this same sanctified status.
Theologians recognize three distinct categories of sanctification: positional, progressive, and ultimate, with positional sanctification understood as fixed and permanent from the moment of salvation.
Scripture repeatedly presents itself as divinely inspired and authoritative for teaching and correction, intended to shape belief and conduct.
Why the Corinthians Had to Receive This Letter as God’s Word
At the opening of 1 Corinthians, Paul describes a congregation already fractured by competing loyalties—some claiming to follow Paul, others Apollos, still others Cephas (1 Cor 1:12). Human opinions were multiplying; a steadier authority was needed.
Paul provides it directly. In 1 Corinthians 14:37–38, he states plainly that his written instructions are “a command of the Lord,” placing his letter above personal preference or rival teaching.
The Corinthians had already written him questions (1 Cor 7:1), acknowledging his role. Clement of Rome later quoted the letter as authoritative, confirming what divided Corinthians genuinely needed: reliable, God-sourced direction. The letter was written from Ephesus, near the end of Paul’s three-year ministry there.
Corinth itself was no quiet backwater—positioned on a narrow isthmus, it served as a major commerce hub connecting the Mediterranean world, drawing people of vastly different backgrounds into one restless, cosmopolitan city. This cultural mixture often produced diverse speech practices that challenged the church’s standards for truthful and edifying words.
Grace and Peace Are More Than a Polite Greeting
When Paul opens 1 Corinthians with the words “grace and peace to you from God our Father and the Lord Jesus Christ” (1 Cor 1:3), he is doing something far more deliberate than offering a customary hello.
Commentaries note that “grace,” from the Greek *charis*, refers to God’s unmerited favor made possible through Christ’s finished work.
Grace is not earned—it is given freely through Christ’s completed work on our behalf.
“Peace,” from *eirēnē*, carries the Hebrew idea of *shalom*—wholeness and restored relationship with God.
Together, these two words compress the entire gospel into a single phrase, signaling that reconciliation with God flows not from human effort but from divine initiative alone. Paul’s deliberate exchange of the standard Greek letter-writing word *charein*, meaning “rejoice,” for *charis*, meaning “grace,” reflects how central grace was to his experience and message.
Grace is not merely the starting point of salvation but an ongoing reality, for the same grace that saves also enables spiritual growth, cleanses after failure, and keeps believers connected to Christ day by day.
Prayer is integral to this relationship, functioning as communication with God that sustains the believer’s connection and dependence.
