O Sacred Lord of ancient Israel, who showed yourself to Moses in the burning bush, who gave him the holy law on Sinai mountain: Come, stretch out your mighty hand to set us free.
Adonai is “Lord.” It was the Hebrew word that the -- Jews used when they found the four-lettered word for God's name which they held to be too sacred to pronounce aloud. Christ is Lord of Creation. We sang this yesterday in the antiphon “O Sapientia”. Christ is also Lord of the Covenant with the People He chose.
The Lord made covenants with Noah, Abraham, and Moses. He guided them and all the People. He gave them Law. He protected and feed them. The Lord delivered them from bondage to Pharaoh and unending slavery. He went before them with arm outstretched.
This was all a pre-figuring of the great work of redemptions that Christ would work on the Cross. He redeemed us His People from Satan and the eternal damnation of hell. He once appeared clothed in the burning bush that was not consumed by fire. He is about to appear again clothed in flesh in our liturgical celebration of Christmas. He will appear again one day in the future to judge the living and the dead. Each day He appears to us in the person of our neighbor.
What amazing contrasts we find in our Lord! He came in thunder and lightning to give the Law on Mt. Sinai. He comes now in swaddling clothes. He will come again in glory. He comes humbly in the appearance of Bread and Wine.
He still goes before us with outstretched arm and our foes are put to flight at the sight of His banner.
