In a previous post we considered the Preface and Proper Preface in the Service of the Sacrament. We saw how these parts of the service fix our attention on what the Lord is about to do in the Sacrament, and introduce and express thanksgiving to God as the end of the Preface is followed by the Proper Preface. We noted that the Proper Preface gives thanks to God as it focuses on a particular part of God’s saving action that we meet in that season of the church year or particular feast day.
But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to innumerable angels in festal gathering, and to the assembly of the firstborn who are enrolled in heaven, and to God, the judge of all, and to the spirits of the righteous made perfect, and to Jesus, the mediator of a new covenant, and to the sprinkled blood that speaks a better word than the blood of Abel. (Hebrews 12:22-23)
In the year that King Uzziah died I saw the Lord sitting upon a throne, high and lifted up; and the train of his robe filled the temple. Above him stood the seraphim. Each had six wings: with two he covered his face, and with two he covered his feet, and with two he flew. And one called to another and said: "Holy, holy, holy is the LORD of hosts; the whole earth is full of his glory!"
Most of the crowd spread their cloaks on the road, and others cut branches from the trees and spread them on the road. And the crowds that went before him and that followed him were shouting, "Hosanna to the Son of David! Blessed is he who comes in the name of the Lord! Hosanna in the highest!" (Matthew 21:8-9)
The crowd was using words from Psalm 118:25-26. In the Old Testament, the Hebrew “Hosanna” meant “save indeed” or “save now.” However, by the time of the New Testament it had become a shout of praise.
The crowd used these words to praise and welcome Jesus as He entered Jerusalem. We now sing them in the Sanctus to greet Jesus Christ as He comes to us in His body and blood in the Sacrament. They prepare us for the miracle that is about to occur in the Sacrament.
