The Outpouring of the Holy Spirit (Pentecost; May 25th, A.D. 33 ):

The Jewish festival of Pentecost (50 days after the festival of the Passover) is also know as Shavuot or the Festival of Weeks and it is one of the 3 mandatory Festivals of Pilgrimage for Jews, which required all the pious Jews living outside of the city of Jerusalem to travel to the temple in Jerusalem to observe the festival. Shavuot has a double significance for Jews. It marks the celebration for all-important wheat harvest in the Land of Israel(Exodus 34:22), to give thanks to God for the divinely granted providence of God for the sustenance to the people of Israel; and it also commemorates the anniversary of the day that God gave the Torah, i.e., the Law of Moses (the stone tablets of the Ten Commandments) to the nation of Israel who were assembled at Mount Sinai. The Torah is the providence of divine justice given to His people. Despite modern self centeredness and narcissistic, of the ruggedly individualistic ears which hear “the law” as God’s shackles upon the people, in fact in a lawful and obedient society “the law” is the divinely providential safe protective boundary for the people. Therefor Shavuot is the people of God thanking God for His providential protection of them. Shavuot occurs 50 days after the Festival of the Passover.
Ten days earlier, on May the 15th in A.D. 33 the Ascension of Christ, God’s Messiah to the right hand of the Father in heaven, had occurred, 40 days after His Resurrection from His saving and restorative death on the cross by which Jesus the Christ atoned for the sins of mankind and restored His fallen creation; He “trampled on death with death!”. Ascension Thursday is 10 days prior to Pentecost (counting inclusively). On Pentecost in A.D. 33, God’s Holy Spirit descended on the Apostles and other followers of Jesus Christ(Luke 22:12–13 & the Acts of the Apostles 2:1–31 ), and they became empowered by God’s Holy Spirit and they spoke in languages, which they did not know, in order to tell the many Jews and foreigners present in Jerusalem for the festival, that God’s promised Messiah had indeed come and that the kingdom of God was at hand.

It is not a coincidence that the day which the Jews set aside to remember God’s providence to them in giving them the Law became the day that Christians remember God giving us the Grace of the Holy Spirit !! The indwelling of God’s Holy Spirit became the mystical union Between God and His Holy Spirit and the faithful believers of Christ which is the basis by which the apostle Paul asserts that God’s Law is written on the hearts of his people(Romans 2:15).
This miraculous indwelling of the Holy Spirit is routinely repeated during the subsequent practice of the Sacrament of the Baptism of the believers who thereby become Christians, and members of God’s church, and for the first time personally experience the mystical union of the believer with the triune God, the Father, The Son, and the Holy Ghost.
