Prayer of the Confiteor Before Holy Mass
I know, O my God, that I am unworthy to be admitted so closely to the Holy of holies, or to be here during the celebration of the sacred mysteries: I am unworthy on account of my many sins. O my God, I beg pardon for them, and I am sure that I will receive forgiveness. I resolve to live a good life so that, purified, I may look up to the sacred mountain, where resides the God Who renews my youth. Yes, I have sinned against Thee, and against heaven. I am not worthy to be called Thy child. Amen.
