The central prayers of the Roman Catholic Mass include the Kyrie Eleison, Sanctus, Agnus Dei, and Gloria, each with its unique place and significance within the liturgy.
Step-by-step explanation:
The prayers central to the Roman Catholic Mass and their correct descriptions are:
A. Kyrie Eleison - A prayer for mercy, traditionally sung in Greek and translated as "Lord, have mercy." It is part of the Penitential Act, where the congregation acknowledges their sins and asks for God's mercy.
B. Sanctus - Also known as the "Holy, Holy, Holy," this prayer is part of the Preface of the Eucharistic Prayer, where the church joins the heavenly beings in praising God and saying, "Holy, Holy, Holy Lord, God of hosts..."
C. Agnus Dei - This is the "Lamb of God" prayer, recited during the breaking of the bread. It asks Jesus, the Lamb of God, to take away the sins of the world and grant us peace.
D. Gloria - The Glory to God in the highest, a hymn of praise to the Trinity. The Gloria is usually recited on Sundays and special feasts outside of the seasons of Advent and Lent.
