Standing at the middle of the altar, the priest forms a circle when he extends, elevates and then joins his hands to entone the Gloria. With this gesture we are reminded of God without beginning, without end.
From The Roman Catholic Daily Missal,1962: “Freed from preoccupation with his sinfulness and confident that God will heal his wretchedness, the Priest intones this cry of joy before the greatness of God’s absolute existence: ‘I am Who Am.’ “
The four ends of the Sacrifice of the Mass are to be found in the Gloria: Adoration, Thanksgiving, Atonement, Petition.
We may pray: “O Bread which came down from Heaven! My treasure, my happiness! What can he who lives by Thee want any more on earth?”
In the N.O. this prayer is rightly called a hymn of praise, but it is much more than just that. In both the TLM and in the N.O. this prayer is at times omitted.
