“I 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, and to all the saints that I have sinned exceedingly in thought, word, and deed, through my fault, through my fault, through my most grievous fault. Therefore, I beseech blessed Mary ever Virgin, blessed Michael the Archangel, blessed John the Baptist, the holy apostles Peter and Paul, and all the saints, to pray for me to the Lord our God. Amen.”
(from the Roman Missal) A Confiteor is a penitential prayer where we acknowledge our sinfulness and seek God’s mercy and forgiveness. Confiteors have been part of Christianity from the beginning. St. Augustine notes that it was traditionally recited while striking the breast as a sign of humility, such as is the custom we have today of doing so during Mass when it is recited. The prayer below is the traditional form of the prayer. It was partially composed in the 8th century and then added to the Mass in the 11th century.
