Topical Lexicon
Origin and Old Testament Background

Pentecost, literally “the fiftieth,” is the Greek designation for the Feast of Weeks (Hebrew Shavuot). Instituted in the Law (Leviticus 23:15-21; Deuteronomy 16:9-12), it fell fifty days after the first Sabbath following Passover and marked the completion of the grain harvest. Worshipers presented “a new grain offering to the LORD” and rejoiced before Him as a pilgrim festival (Exodus 23:16). The day therefore celebrated God’s faithful provision and pointed forward to a fuller harvest yet to come.

Fulfillment in Acts 2

“When the day of Pentecost came, they were all together in one place” (Acts 2:1). The risen Christ had promised the baptism of the Holy Spirit (Acts 1:5), and at precisely the divinely appointed feast the promise was realized. The Spirit was poured out with audible wind, visible tongues of fire, and multilingual praise (Acts 2:2-4). Peter linked the event to Joel’s prophecy, declaring, “In the last days, says God, I will pour out My Spirit on all people” (Acts 2:17). Three thousand were added that day, a firstfruits harvest of souls corresponding to the grain firstfruits offered under the Law. Thus Pentecost becomes the birthday of the Church and the inaugural sign that the New Covenant era had dawned.

Continuing Apostolic Practice

The remaining New Testament occurrences show Pentecost as a calendrical anchor for ministry planning:
Acts 20:16 — Paul hurried to reach Jerusalem “by the day of Pentecost,” honoring the feast’s significance and expecting a gathering of worshipers there.
1 Corinthians 16:8 — He told the Corinthians, “I will stay in Ephesus until Pentecost,” using the feast to mark a strategic season of effective service (verses 8-9). These notices indicate that the early Church, while liberated from Mosaic ritual obligation, still recognized the feast’s timing and evangelistic potential when pilgrims gathered.

Theological Themes

1. Harvest and Firstfruits: The agricultural imagery of the feast is fulfilled spiritually in the ingathering of believers (James 1:18).
2. Law and Spirit: Fifty days after Israel received the Law at Sinai, the Church received the Spirit in Jerusalem, highlighting the superiority of the New Covenant written on hearts (Jeremiah 31:33; 2 Corinthians 3:6).
3. Unity in Diversity: Languages once confused at Babel are harmonized in praise, showcasing the gospel’s reach “to every nation under heaven” (Acts 2:5).
4. Empowerment for Witness: Pentecost equips disciples for the Great Commission (Acts 1:8), confirming that gospel advance depends on the Spirit’s power, not human strength.

Practical Implications for the Church

• Reliance on the Spirit: Believers are to depend daily on the same empowering presence granted at Pentecost (Galatians 5:16-25).
• Expectation of Harvest: The festival’s firstfruits encourage confidence that a greater ingathering will follow; missions and evangelism flow naturally from Pentecost theology.
• Celebration of Unity: The Spirit creates one body from many nations (Ephesians 2:18-22), calling the Church to model reconciled community.
• Hope for Consummation: Just as Pentecost followed Passover, so the Spirit-firstfruits guarantee the full redemption awaiting Christ’s return (Romans 8:23).

Pentecost therefore stands at the intersection of Israel’s sacred calendar, Christ’s redemptive work, and the Church’s ongoing mission, testifying to God’s faithfulness from seedtime to final harvest.
