YOUCAT Question n. 214 - Part I. How is the Mass structured?

Youcat answer:

Holy Mass begins with the gathering of the faithful and the entrance of the priest and the others who serve in the sanctuary (altar servers, lectors, cantors, and so on). 

After the greeting comes the Penitential Rite, which oncludes with the Kyrie. On Sundays (outside of Advent and Lent) and feast days, the Gloria is then sung or recited. 

The prayer of the day introduces one or two readings from the Old and New Testament, followed by the responsorial psalm. Before the Gospel is read, there is an Alleluia, or acclamation. 

After the proclamation of the Gospel on Sundays and feast days, the Priest or Deacon gives a Homily at least on Sundays and feast days. Then, again only on Sundays and feast days, the congregation professes its common faith in the Creed, followed by the intercessions. 

The second part of Holy Mass begins with the preparation of the gifts, which concludes with the Offertory prayer. The high point of the Eucharistic celebration is the Eucharistic Prayer, which is introduced by the Preface and the Sanctus. Now the gifts of bread and wine are transformed into the Body and Blood of Christ. The Eucharistic Prayer concludes, finally, in the Doxology, which makes the transition to the Lord’s Prayer. 

Then comes the prayer for peace, the Agnus Dei, the breaking of the bread, and the distribution of the holy Gifts to the faithful, which often is done only under the form of the Body of Christ. Holy Mass ends with meditation, thanksgiving, a concluding prayer, and a blessing by the priest. [1348-1355]

The Sanctus: Holy, Holy, Holy Lord God of hosts. Heaven and earth are full of your glory. Hosanna in the highest. Blessed is he who comes in the name of the Lord. Hosanna in the highest. Latin: Sanctus, Sanctus, Sanctus Dominus Deus Sabaoth. Pleni sunt caeli et terra gloria tua. Hosanna in excelsis. Benedictus qui venit in nomine Domini. Hosanna in excelsis.
