The Lighter Side

The church's birthday. Wear red. No cake, which seems like an oversight for a birthday.

The longer version

What it means

Pentecost is the day the church was born. Fifty days after Easter, ten after Jesus' ascension, His followers were gathered in Jerusalem when, as Acts 2 tells it, a sound like wind filled the house, tongues of fire rested on each of them, and they began speaking in languages they didn't know. Peter preached, three thousand believed, and the community that would become the church began. Christians celebrate it as the coming of the Holy Spirit — the moment Jesus' promise to send a Helper was kept — and as the day the gospel first went public.

Liturgical churches mark it with red vestments and decorations, readings of Acts 2 (sometimes in many languages at once), and, in some places, confirmations. It closes the Easter season.

Why people say it

Christians believe the Holy Spirit is God present in and among His people, and Pentecost is where that presence arrived in force. Without it, Jesus' followers were a frightened group in an upper room; after it, they were a movement. The day is a reminder that the church runs on God's power, not its own — and, for Pentecostals, a promise that the same power is available now.

How to respond

If you're at a liturgical church on Pentecost, expect red, Acts 2, and possibly the reading in multiple languages; it's a joyful day. If someone tells you it's the church's birthday, that's what they mean. If someone asks why the day matters, the short answer is: it's when the Spirit came and the church started. If you're wondering why Pentecostals are called that, now you know.

If you hear it in different churches

Catholic, Orthodox, Anglican, Lutheran, Methodist, and Presbyterian churches celebrate it as a major feast. Orthodox call it Holy Trinity Day and decorate with greenery. Pentecostal churches celebrate the day and see it as their charter — the Spirit's gifts are for now. Baptist and evangelical churches often preach Acts 2 on the Sunday but may not name the feast. "Whitsunday" (White Sunday, for the baptismal robes) is the old English name.

Where does “Pentecost” come from?

Pentecost was a Jewish harvest festival, Shavuot, fifty days after Passover (Leviticus 23), which is why Jerusalem was full of pilgrims "from every nation" in Acts 2. Peter interprets the events through Joel 2: "I will pour out My Spirit on all people." Christians celebrated the day from at least the 200s, and it became one of the three great feasts with Christmas and Easter. The modern Pentecostal movement took its name from the day after the Azusa Street Revival of 1906, whose participants believed the Acts 2 experience had returned.

Acts 2:1–41Joel 2:28–32John 14:16–17Leviticus 23:15–21John 20:22

Good to know

Pentecost is the third great feast of the church year after Christmas and Easter, and the least known outside the church. The color is red, for the tongues of fire; the readings are Acts 2. Pentecostal Christians take their name from the day, believing its events — the Spirit's coming with power and speaking in tongues — are a pattern for today. Non-Pentecostal churches celebrate the day without expecting a repeat.
