Background

The day of Pentecost was already a well-established Jewish festival — Shavuot, the Feast of Weeks — celebrated fifty days after Passover to commemorate the giving of the Torah at Sinai and the first fruits of the wheat harvest. Jerusalem at Pentecost was packed with diaspora Jews from across the known world: Parthia, Media, Elam, Mesopotamia, Egypt, Libya, Rome, Crete, and Arabia. Approximately 120 followers of Jesus had remained in Jerusalem as he commanded (Acts 1:4), gathered in continual prayer following his ascension. The prophet Joel had promised that in the last days God would pour out his Spirit on all flesh — sons and daughters, old men and young men, servants and free (Joel 2:28–32). Jesus himself had promised the Father would send another Advocate to be with his disciples forever (John 14:16–17).

The Event

At nine in the morning, a sound like a violent rushing wind filled the house where the disciples were gathered. Tongues of flame appeared and rested on each individual. They were all filled with the Holy Spirit and began speaking in other languages as the Spirit enabled them (Acts 2:4). The multilingual crowd in Jerusalem heard — each in their own native tongue — the disciples declaring the mighty acts of God. Some were astonished; others mocked, accusing them of drunkenness. Peter stood with the eleven and preached. He anchored the event in Joel's prophecy, narrated the life, death, and resurrection of Jesus as the climax of Israel's story, and declared him both Lord and Christ. When the crowd cried out, "What should we do?" Peter called them to repentance and baptism in the name of Jesus Christ. About three thousand people were baptized that day and devoted themselves to apostolic teaching, fellowship, breaking of bread, and prayer.

Theological Significance

Pentecost is the founding event of the Christian church. What had been promised through the prophets, inaugurated in Jesus' ministry, and secured through his death and resurrection was now applied to human hearts by the poured-out Spirit. The reversal of Babel — one Spirit enabling proclamation across every language barrier — signaled the beginning of the gathering of the nations. Joel's "last days" had arrived; the age of the Spirit had begun. The three thousand added on that day would carry the Gospel back to their home regions across the empire. Pentecost also marks the transition from the disciples as a group of followers to the church as a community of witnesses empowered for mission — the body of Christ in the world, indwelt by the same Spirit who raised Jesus from the dead (Romans 8:11).
