On Pentecost Sunday (Year B), Fr. Anthony Ho explains to us the events surrounding the descent of the Holy Spirit on the apostles in the Acts of the Apostles and the Gospel of John. The Holy Spirit is the life and movement within the Church, bringing us wisdom and courage. Through the power of the Holy Spirit, we can be united in one heart and mind, like the apostles in giving witness to God, receiving a deep sense of joy and peace.
