Something many Christians do not realize is that Pentecost (or Shavuot) is a Jewish holiday celebrated on the fiftieth day after the Feast of Unleavened Bread. Originally a time of thanksgiving for the wheat harvest, Shavuot also commemorates God’s giving of the Law to Moses.
On that day in the upper room the Apostles were devoting themselves to prayer according to their tradition. And, just as the Law of Moses unified Israel, the events of this particular Shavuot following the Ascension of Christ, when the apostles received the Holy Spirit, gave birth to the Christian Church.
Imagine the energy! The Apostles, Jesus’ mother, Mary, some women, and his brothers (Acts 1:12-14) were together in the upper room pouring themselves into prayer. They were afraid and confused. We can imagine their discussions as they expressed to one another all that they knew of recent events–what they knew to be true. They prayed together. And the Holy Spirit responded by igniting within them a holiness that manifested itself in language, a language which needs no translation. The Spirit becoming Word. The Word made flesh!
Then they left the safety of the upper room and went out into the streets and astonished everyone with their passion for sharing the Word.
When we speak of the mighty acts of God, we speak the same language.
It is that same Holy Spirit which drives each one of us to share the good news of Jesus Christ. Let us celebrate the fulfillment of Pentecost—the birth of the Church—by recalling the Shavuot, by devoting ourselves to prayer, contemplating the living Body of Christ in whom we dwell, and by allowing the Holy Spirit to ignite our passion for sowing the Gospel seeds!

I think you’re wrong by saying it was fulfilled completely.

Brandon, Thank you for reading and commenting. However, I don’t know what you are referring to. Where in this reflection do I say “it was fulfilled completely?” And what is the “it” that you are referring to?
