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.

(strike your breast three times with the following:)
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.
