Bowing down, the Priest makes his confession to prepare himself to celebrate the Sacrifice. His prayer is answered by the server:
ONFITEOR Deo omnipotenti, beatae Mariae semper Virgini, beato Michaeli Archangelo, beato Joanni Baptistae, sanctis Apostolis Petro et Paulo, omnibus Sanctis, et vobis fratres, quia peccavi nimis cogitatione verbo, et opere: (Percutit sibi pectus ter, dicens) mea culpa, mea culpa, mea maxima culpa. Ideo precor beatam Mariam semper Virginem, beatum Michaelem Archangelum, beatum Joannem Baptistam, sanctos Apostolos Petrum et Paulum, omnes Sanctos, et vos fratres, orare pro me ad Dominum Deum nostrum.
V. Misereatur tui omnipotens Deus, et dimissis peccatis tuis, perducat te ad vitam aeternam.
CONFESS to Almighty God, to Blessed Mary ever Virgin, to Blessed Michael the Archangel, to Blessed John the Baptist, to the Holy Apostles Peter and Paul, to all the angels and Saints, and to you, brethren, that I have sinned exceedingly in thought, word and deed: (He strikes is breast three times) through my fault, through my fault, through my most grievous fault. Therefore I beseech the Blessed Mary ever Virgin, Blessed Michael the Archangel, Blessed John the Baptist, the Holy Apostles Peter and Paul, all the Saints, and you, brethren, to pray for me to the Lord our God.
V. Almighty God have mercy on you, and forgiving you your sins, bring you to life everlasting.
