The Siddur liturgy succinctly summarizes the treasured place of the Sabbath in Jewish tradition with these words: “Last in creation, first in intention.” Shabbat is the crown of creation and the first thing made holy by the Creator. "Then God blessed the seventh day and sanctified it" (Genesis 2:3). The six days of creation are "good" but only the seventh day is "hallowed"
"Then celebrate the Feast of Weeks to the LORD your God ... "(Deuteronomy 16:10).
Scripture gives the festival of Shavuot three distinct names in relation to its agricultural settinj;l: "Feast of Harvest;' "Feast of Weeks;' and' Feast of First Fruits:' Though the festival is celebrated in this agricultural setting, the greater significance of Shavuot is as a celebration of God's gift of the Torah to the Israelites. He made its revelation for the following generations as real as the harvest around them.
The book of Acts reports the fulfillment of a universal covenant when the message of the God of Israel reached out to the Gentiles, "devout men from every nation under heaven'' (Acts 2:5), and even identifies some of them: Parthians and Medes and Elamites, those dwelling in Mesopotamia, Judea and Cappadocia, Pontus and Asia, Phrygia and Pamphylia, Egypt and the parts of Libya adjoining Cyrene, visitors from Rome, both Jews and proselytes, Cretans and Arabs-we hear them speaking in our own tongues the wonderful works of God. (Acts 2:9-11)
What is the value and the authority of the ancient law of Moses for the modern man, Jewish or Christian?
We do not understand the nature of law in the Bible if we reduce it to a chore which alienates human beings and deprives them of their freedom. This truth is affirmed in the Bible from the start.
The first steps of Adam just created from dust, as well as the first steps of the people of Israel just liberated from Egypt, are engaged on the rhythm of the law (Genesis 2:4, 16; Exodus 20). In the tradition of Israel, the law is in fact associated with liberty.
In the liturgical Christian churches that observe the traditional church year there is a festival called Pentecost. It is also called Whitsunday because it was customary for newly baptized persons to wear white robes on that Sunday. Churches were decorated with green branches and trees. It is regarded as the birthday of the Christian church and the festival of the Holy Spirit. This day has a fascinating back story that is rooted deep in the Tanakh and Jewish tradition.
The Feast of Shavuot (“Weeks”) is the second of three pilgrim festivals in the annual round of holy days described in Torah. In biblical times Shavuot was a one; day festival, occurring on the sixth day of the third Jewish month Sivan (in our modern calendar, late May or early June). In later Jewish practice a second day of the festival was added for those living in the Diaspora (outside the land of Israel).
