For one more year it is Pentecost 50 days after the celebrated Easter (Resurrection of Christ), we celebrate the feast that marked the birth of the Church as a Body of Christ that is binding all its members us the ordinary people who are baptized in the Name of The Father, The Son and The Holy Spirit.
Pentecost is a day of mystery that turned human history, as the same Spirit who was in Christ and has been in the Father in the Holy Trinity has descended from Heaven sent as a helper to each and every believer in Christ to strenghten and guide him in his narrow path to the Kingdom of Heaven and the Eternal salvation promised by the Savior Christ.
There is many books written about Pentecost but no book or intellectual thought is capable to transpond one's experience of receiving the Holy Spirit in the Soul and Heat of man. This glorious event is experienced by every Christian during baptism and the following Mystery of Chrismation when the Priest baptizes a new member in the name of God and is experienced, by us in the mystery of repentence when crying for our bad deeds and transgressions of the law of God, we cry in sorrow to God asking for forgiveness and renewal. The descent of the Holy Spirit over us is supernatural event that put the beginning of the contemporary understanding in our contemporary civillization of supernaturality and the realm of spirits as we understand them today where the Spirit of God is over all things.
On Pentecost it is the Holy Spirit who descended towards the Holy Apostles giving them the Super natural powers to Heal The Sick, Prophecise, speak in all human tongues, chase away evil spirits and do multitude of unseen wonderworks in human history that are continuing even to this day in the Church. The Holy Spirit has gifted all Church members with the gifts of the Spirit of Faith, Hope and Love, Endurance, Manhood, and all the virtues of man that were in Christ not because of a human effort but for the Love of God for man.
The abiding of the Holy Spirit in man is a never ending Heaven and a bliss granted for man for free. Saint Seraphim of Sarov has well described in his Conversation with Motovilov what is the experience to have the God the Holy Spirit in One's self.
A bit more on the facts around the Descent of the Holy Spirit to the Apostles is in my prior article here , though this is just a very basic attempt to transfer the meaning of the feast as definitely all the books on the earth and all the human knowledge put together is like a drop in the universe compared to Holy Spirit itself.
The Spirit of Truth which the world could not comprehend was sent by Jesus Christ first to the apostles and the desciples and then to each and every Christian member of the One Holy Eastern Orthodox Church throughout human history until the end of ages.
