Who cited the prophecy of Joel during his message on the Day of Pentecost?

The citation of the prophecy of Joel during the Day of Pentecost is attributed to Peter. In the Book of Acts, particularly Acts 2, Peter delivers a powerful message following the outpouring of the Holy Spirit. He references the prophecy from the Book of Joel, which speaks about the outpouring of the Spirit upon all people as a sign of the last days. This inclusion is significant because it helps validate the transformative event of Pentecost as a fulfillment of scripture, emphasizing that the movement of the Holy Spirit is rooted in the prophetic tradition of the Hebrew Scriptures.

Peter's use of the Joel prophecy not only demonstrates his understanding of the scriptures but also positions the events of Pentecost within the broader narrative of salvation history. This moment marks a pivotal shift in the early church as it affirms the role of Jesus Christ as the Messiah and the empowerment of believers through the Holy Spirit for the mission of spreading the gospel.
