We complete the fifty-day celebration of Easter with the feast of Pentecost, the coming of the Holy Spirit upon the apostles. As the world was transformed when Christ was born, making God incarnate in our world, the world is transformed once more with God's gift of the Holy Spirit to all who are baptized, making God present continuously and forever in our world. Indeed, the Holy Spirit has gathered us together today to praise and worship our everlastingly generous God. It could be said the climax of all the readings we will hear today comes in the very first paragraph of the first reading. A strong driving wind ... tongues of fire ... speaking in tongues. The Holy Spirit made quite the entrance! But the special effects are only the beginning. With the Holy Spirit, the apostles could be understood by every foreigner, no matter their native language. With the Holy Spirit, we have God dwelling in us, uniting us as one. With the Holy Spirit, we have the fulfillment of Jesus' parting promise to his disciples, God's abiding gift to us. Let us be aware of the Holy Spirit within us as we listen to God's word.
