The Christian celebration of the outpouring of the Holy Spirit upon Mary and the disciples of Jesus is celebrated at Pentecost, that is, on the fiftieth day of Easter. We read in the Acts of the Apostles: “When the day of Pentecost came, they were all together in one place. Suddenly a sound like the blowing of a violent wind came from heaven and filled the whole house where they were sitting. They saw what seemed to be tongues of fire that separated and came to rest on each of them. All of them were filled with the Holy Spirit and began to speak in other tongues as the Spirit enabled them.” (Acts 2:1-4).
Chiara Lubich wrote when referring to the charism of unity: “The Holy Spirit is the gift that Jesus gave to us so that we might be one as He and the Father are one. Of course, the Holy Spirit was in us to begin with, since we were Christians; but here there was a new illumination, a new manifestation of the Spirit among us, which made us participants and actors in a new Pentecost, along with those ecclesial Movements renew the face of the Church.”
