“Πεντηκοστή” (Pentēkostē), the fiftieth day from Easter is a unique and special day of celebration for the Church. This day represents the birth of Christianity and celebrates the permanent arrival of the Holy Spirit into the lives of Jesus’ followers. On this day, expressions of joy and worship flow from believers in celebration of the indwelling (fire) presence of the Spirit of God. Pentecost Sunday is a reminder for each of us that God’s Holy Spirit is now available to all who repent of their sins, are baptized, and continue to follow and obey Him.
