definition of pentecost: 7 Essential Surprising Facts in 2026

Introduction

The definition of pentecost is layered, historical, and still meaningful for millions around the world. It names a festival, a theological moment, and a story that links Jewish and Christian calendars. A short word, big history.

What Does definition of pentecost Mean?

At its simplest, the definition of pentecost describes a festival that takes place on the fiftieth day after Easter in Christianity, and the fiftieth day after Passover in Judaism. In Christian use it often refers to the event recorded in Acts 2 where the Holy Spirit descended on the apostles. That event is commonly called the birth of the Christian church.

So the phrase covers both the liturgical feast and the theological claim that God empowered the early followers of Jesus in a decisive way. The term is used in sermons, calendars, and everyday conversation in churches of many traditions.

Etymology and Origin of definition of pentecost

The word pentecost comes from the Greek pentekoste, meaning fiftieth. That Greek term translated a Hebrew festival name, Shavuot, the festival of weeks. Both mark a day count: fifty days after an earlier holiday.

In the New Testament pentecost appears as the stage for a dramatic story in the book of Acts. Luke borrows the term from Jewish practice and uses it to date the arrival of the Spirit. Over centuries, that single narrative helped the word move from calendar label to theological symbol.
