Accompany the priest to the altar. When he goes up the steps, kneel at the side and begin the Confiteor bowing:
CONFITEOR

PETRO ET PAULO, OMNIBUS SANCTIS, (Without turning) ET TIBI PATER, QUIA PECCAVI NIMIS COGITATIONE, VERBO ET OPERE, (Strike your breast three times)

SANCTOS APOSTOLOS PETRUM ET PAULUM, OMNES SANCTOS, (Without turning) ET TE, PATER, ORARE PRO ME AD DOMINUM DEUM NOSTRUM.
Remain bowing:
P. Misereatur vestri, omnipotens Deus; et dimissis peccatis vestris perducat vos ad vitam aeternam.
S. AMEN.
Upright. Sign of the Cross.
P. Indulgentiam,
absolutionem, et remissionem peccatorum nostrorum tribuat nobis
omnipotens et misericors Dominus.
S. AMEN.
Take the Communion Plate to the communicants. During Communion pray to Our Lord in your own words. Or repeat over and over again:
O Sacrament most holy, O
Sacrament divine, All praise and all thanksgiving be every moment
Thine. Praised be Jesus Christ, praised forevermore be Jesus in the
most adorable Sacrament of the altar.
On returning to the Altar the Priest says this prayer:
O sacred Banquet, wherein Christ is received; the memory of His Passion renewed;
the mind filled with grace; and the pledge of future glory given to us. (Alleluia).
P. Panem de caelo praestitisti eis, (Alleluia).
S. OMNE DELECTAMENTUM IN SE HABENTEM (ALLELUIA).
P. Domine, exaudi orationem meam.
S. ET CLAMOR MEUS AD TE VENIAT.
P. Dominus vobiscum.
S. ET CUM SPIRITU TUO.
P. Oremus.
O
God, Who dost remind us of Thy Sacred Passion by this mystery of Thy
Body and Blood, grant that we may so love this sacrament that we
receive abundantly the graces of redemption.
P. Per omnia saecula saeculorum.
S. AMEN.
P. Benedictio Dei omnipotentis, (Sign of the Cross) Patris, et Filii, et Spiritus Sancti, descendat super vos et maneat semper.
S. AMEN.
