Pentecost is one of the most important Christian holidays in the calendar. It’s a joyous celebration that commemorates the descent of the Holy Spirit upon Jesus' disciples. Here's a look at the history and observance of Pentecost Sunday.

What is the Day of Pentecost?

The Day of Pentecost occurs on the seventh Sunday after Easter. As such, the actual date of Pentecost celebrations shifts from year to year. In 2022, it will occur on Sunday, June 5th.

The early church considered the entire period of the 50 days following Easter to be Pentecost, but in modern times, Pentecost is mostly understood to refer to a single day. This holiday was established to mark a crucial event in Christian history—the moment when God gave humanity His divine guidance through His spiritual representative on Earth: the Holy Spirit.

What Happened at Pentecost?

Pentecost commemorates the descent of the Holy Spirit upon the Apostles and other followers of Jesus Christ while they were in Jerusalem celebrating the Feast of Weeks, as written in the Acts of the Apostles (Acts 2:1–31).

On that day, as Jesus’ disciples were eating together, they received power from God described as "tongues of fire" and began speaking in foreign languages (Acts 2:4). This was considered proof that they had been filled with the Holy Spirit and thus were able to preach Christ's message to all nations as He had commanded them (Matthew 28:19). In addition to speaking in tongues as evidence of their baptism with the Holy Spirit, these Christians experienced miracles such as healing and even raising someone from the dead.

The day of Pentecost is significant because it marked the receipt of the Holy Spirit as well as the beginning of the Christian Church.

What Does Pentecost Mean?

"Pentecost'' is derived from the Greek word pentekostos, which means "fiftieth." This is a nod to the fact that it's celebrated 50 days after Easter. This number has also been interpreted by some as a reference to Jesus's age when he was crucified, or to the Jewish festival of Shavuot, which was held 50 days after Passover.

In the UK, Pentecost came to be known as Whitsunday or Whit Sunday, in reference to white garments worn by people who celebrated Pentecost at church. The Roman Catholic Church considers it to be the feast of Saint John the Baptist. Eastern Orthodox Churches observe this feast with other related events, while Protestant churches often observe it simply as "Pentecost."

Whatever name you know it by, Pentecost is a historic holiday that’s been celebrated for thousands of years and still endures today. It reminds us that the Holy Spirit is always with us to guide and direct our lives, and to help us with biblical understanding.

Here at the Massachusetts Bible Society, we’re dedicated to promoting biblical literacy. Biblical texts have been interpreted in diverse ways from generation to generation and are always filtered through the lens of the reader’s faith and life experiences. The Bible has authority for communities of faith who take time to study and prayerfully interpret its message, but it is also important for anyone who wants more fully to understand culture, religious thought, and the world in which we live. We believe that everyone should know the Bible, whether they accept it as their sacred text or not. To that end, we have created accessible and comprehensive resources for all who are curious.
