Act of Penitence, Form A (Confiteor)

I confess to almighty God, and to you, my brothers and sisters that I have greatly sinned, in my thoughts and in my words, in what I have done, and in what I have failed to do, through my fault, through my fault, through my most grievous fault; therefore I ask blessed Mary, ever virgin, all the Angels and Saints, and you, my brothers and sisters, to pray for me to the Lord, our God.

Confiteor
Confiteor Deo omnipotenti, beatae Mariae semper Virgini, beato Michaeli Archangelo, beato Joanni Baptistae, sanctis Apostolis Petro et Paulo, omnibus Sanctis, et vobis, fratres (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 vos, fratres (et te, pater), orare pro me ad Dominum Deum nostrum. Amen.
