Confiteor Deo omnipotenti, beatae Mariae semper virgini, beato Michaeli archangelo, beato Joanni Baptistae, sanctis Apostolis Petro et Paulo, omnibus Sanctis, et tibi, Pater, quia peccavi nimis cogitatione, verbo, et opere, 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 te, Pater, orare pro me ad Dominum Deum nostrum.
