Pentecost is one of the great feasts of the Church based on Scriptural accounts of the descent of the Holy Spirit. The name comes from the Greek word "fifty." This title was applied to the Jewish "Feast of Weeks" which is the fiftieth day after Passover. Later, the Church assigned the commemoration to the fiftieth day after Easter. The other name, meaning "White Sunday," comes from the northern European custom of administering Baptism to white-robed candidates on this feast.
The Gospel for Pentecost (St. John 14: 15-31) continues the recent series from Christ's Farewell Discourses. For me, a key verse in the selection is this: But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsover I have said unto you (St. John 14: 26). In view of all the strange things that some Christians have attributed to the Spirit over the centuries, this verse provides important guidance. 1) The Holy Ghost comes from the Father in Christ's name: His work is inseparable from the saving work of the Father and the Son. 2) The work of the Spirit is not primarily emotional; the Spirit mainly comes to teach Christ's disciples. 3) As the Spirit teaches, there is not a distinct new revelation. Rather the Spirit brings to remembrance what has already been revealed in the words of Jesus. Thus, if Christians "feel" that the Holy Spirit is leading them in a certain direction, they need to examine their feelings in light of the truth of the whole Biblical revelation, especially in light of Christ's words in the Gospels.
