Today is the Feast of Pentecost. It is celebrated fifty days after Easter and ten days after the Ascension. Pentecost marks the coming of the Holy Spirit and the birthday of the Church. It is the third most important feast after Easter and Christmas. You can find the story in Acts 2:1-41. The dramatic entry of the Holy Spirit in wind and fire is reminiscent of the dedication of the tabernacle (Exodus 40) and of the temple (2 Chronicles 7). The suggestion is that the disciples of Jesus now embody the presence and glory of God.
