The Benedictine Confiteor
If you ever find yourself serving mass for a Benedictine priest, then you will need to pray a slightly altered (no pun intended!) Confiteor. The two changes, which are actually additions, are bolded in the text below.
Confiteor Deo omnipotenti, beatæ Mariæ semper Virgini, beato Michaeli Archangelo, beato Ioanni Baptistæ, sanctis Apostolis Petro et Paulo, beati Patri nostro Benedicto, 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 Ioannem Baptistam, sanctos Apostolos Petrum et Paulum, beatum Patrem nostrum Benedictum, omnes Sanctos, et te Pater, orare pro me ad Dominum Deum nostrum. Amen.
