What is the context?
The message about the crucified and risen Jesus cuts the listeners to the heart. They ask Peter and the other apostles what they should do. Peter calls them to repent and be baptized in Jesus Christ’s name, speaks of forgiveness, and promises the gift of the Holy Spirit.
The promise reaches the listeners, their children and those far off, all whom the Lord calls. Peter continues to warn and urge them. Luke’s summary is brief; it is not a transcript of every word spoken that day.
Those who receive the message are baptized, and about three thousand people are added. The response becomes a shared life, described in the next passage. The crowd is being called to turn toward the Jesus Peter has proclaimed, not simply to have an emotional reaction to the signs.
How is this passage commonly understood?
Christians agree that repentance, baptism, forgiveness and the Spirit belong closely together in this response. They differ over how baptism brings God’s grace and who should receive it.
The Catholic Church’s Catechism, paragraphs 1226–1228, directly cites Peter’s words and describes baptism as a life-giving sacrament joined to faith, purification and communion with Christ’s death and resurrection. Paragraphs 1257–1259 also recognize that God is not bound by the sacraments and discuss baptism of blood and the desire for baptism. This teaching should not be reduced to a claim that water works independently of God or faith.
The Reformed Westminster Confession, chapter 28, calls baptism a sign and seal of God’s covenant, including forgiveness of sins. It teaches that the Spirit truly confers the promised grace according to God’s purpose, while denying that every baptized person is necessarily given new life or that salvation is inseparably tied to the time of the water rite. It includes the infants of believers among those to be baptized.
The 1689 Baptist Confession, chapter 29, also describes baptism as a sign of fellowship with Christ, forgiveness of sins and new life. It limits those baptized to people who profess repentance, faith and obedience, and requires immersion. That differs from Westminster’s inclusion of believers’ infants and its acceptance of pouring or sprinkling.
Wesley on verse 38 emphasizes repentance, belief in Jesus and the Spirit’s continuing fruits. He does not identify the promised gift here simply with everyone receiving the power to speak in tongues. The different readings need to keep the whole call to respond in view, rather than treating one word as if it supplied the entire teaching by itself.
Where does this fit in God's plan?
Peter’s invitation carries forward the promise at the end of the Joel quotation: the Lord calls people to salvation, and they are to respond to Him. The address includes children and those far away without giving us a complete timetable for every community that will later hear.
Acts 10:44–48 will show Gentiles receiving the Spirit and then being baptized. That later event belongs to the same expanding story of God’s gift. Reading the accounts together helps us hear the continuing mission without assuming every conversion scene must follow an identical sequence.
What is our position?
Baptism reads Acts 2:38 as describing the whole response to the gospel: repentance, forgiveness, baptism and the Spirit belong together. It rejects a fixed formula in which nothing spiritual can happen before the water rite, pointing to the Gentiles receiving the Spirit before baptism in Acts 10. Baptism is the expected response of faith; this conclusion does not make it something to neglect.
