Entry practice of repentance, baptism, and receiving the Holy Spirit

The entry practice of repentance, baptism, and receiving the Holy Spirit is Luke-Acts’ account of how people respond to the Realm of God and join its movement. Repentance turns people from the old age toward God and the coming Realm; baptism signifies forgiveness and incorporates them into the community; the gift of the Spirit empowers that community to witness. Together, these practices describe a change of allegiance and a shared way of life, not simply a set of rites for individuals.

The pattern and its meaning

Peter’s Pentecost audience asks what it should do in response to his preaching. Luke’s answer is a full-bodied response: repent, be baptized, and receive the Holy Spirit. Each element marks a different but connected dimension of entry into the Realm’s community. Repentance means turning away from the old age and turning toward God and the coming Realm. In Luke’s account, sin is complicity with the old age; forgiveness means that a person is no longer determined by that order.

Baptism, understood as immersion, assures people that God has forgiven their sins and initiates them into the community of the Realm. It is therefore both a sign of release from the old age and a passage into a communal life ordered by a different future. The Holy Spirit is not an optional addition to this account of entry: the Spirit equips the community for its witness. Repentance, baptism, and reception of the Spirit together make the response bodily, communal, and directed toward mission.

Pentecost and the community’s mission

The practice belongs within Luke’s wider understanding of mission. Acts 1:4 and 8, read with Luke 24:46 and Acts 2:38, offer a compact account of a community called to witness to the Realm and invite people into the movement toward it. Repentance, baptism, and receiving the Spirit are joined to witness through the life of the community. They are not an end in themselves: they form people for participation in a community whose existence makes the Realm visible.

The lectionary’s reading of Acts 2:1–21 on Pentecost captures the event, its manifestation and initial response, and the beginning of Peter’s sermon, but stops before the sermon’s conclusion. Reading or summarizing Acts 2:22–36 and continuing with 2:37–39 makes the movement clearer: the hearers’ response is bound to the claim that they belong to an eschatological community empowered by the Spirit. Through repentance, baptism, and the gift of the Spirit, God prepares that community to bear witness.

A promise that crosses boundaries

The promise is not restricted to the immediate Jewish audience. Peter’s proclamation extends it to those who are far away, understood in the discussion as Gentiles. This outward reach fits the larger witness that moves from Jerusalem and Judea through Samaria toward the ends of the earth. Luke presents faithful witness as enlarging the community: as its boundaries expand, the church becomes more inclusive.

That expansion does not mean that Jewish listeners are urged to leave Judaism and convert to a separate religion. In Luke’s historical and theological framing, Christianity had not yet separated from Judaism as a distinct religion. The church does not replace Judaism; it is a community with Jewish roots and a distinctive Jewish end-time perception. Peter’s invitation is to join a community whose witness remains Jewish in its origins and orientation, while also carrying the promise outward. The entry practice thus serves inclusion without erasing the tradition from which the movement comes.

The life that follows entry

Acts 2:42 describes the communal life that follows this response through four interrelated practices. The community follows the apostles’ teaching, Luke’s interpretation of the story of Jesus and of the church. It shares fellowship, or koinonia, which includes mutual support and may include financial assistance. Its members break bread, continuing to participate in the eschatological banquet associated with Jesus’ final meal. They also pray for the coming of the Realm. The practices of entry open into teaching, mutual care, shared table, and prayer rather than ending at baptism.

The same communal standard appears in the account of the community’s care for widows. Acts 6:1–7 depicts a developing movement whose internal life had not yet embodied the Realm’s concern that all people live together in mutual support. The community responds by organizing care and appointing seven people as mission team leaders, not simply establishing permanent offices in a formal institutional structure. The episode gives the entry practice a social consequence: belonging to the Realm’s community calls for arrangements that make mutual support real.

A continuing measure of the church

Because Luke writes for an established congregation, the pattern also functions as a measure for examining communal life. The relevant questions are not only whether people have repented, been baptized, or received the Spirit, but whether the congregation lives in a way that befits repentance, embodies its baptism, lives in the Spirit, and communicates the promise to those who are far away. Entry is therefore both a beginning and an ongoing test of the community’s conduct and mission.

The pattern also resists treating evangelism as the recruitment of people who are already Christian. Luke’s account offers a starting point for considering how congregations might extend repentance, baptism, and the gift of the Spirit to people who have never belonged to a church. Its measure of success is not simply membership growth: the church’s witness should cross literal and symbolic distances, enlarge the circle of belonging, and form a community whose shared life points toward the Realm.
