Prayers Before and After Sacramental Penance

AND since I have so grievously insulted thee, O most tender and loving God, by my manifold sins and negligences, I am ready now to make perfect satisfaction to thy divine justice to the utmost of my ability. To this end I will faithfully and most reverently perform the penance appointed me by my confessor in thy name; and would that I could perform it with so great devotion and love as to give thee an honour and delight greater than the insult and outrage of my sins! And that this may be so, I unite and blend this my penance with all the works of satisfaction which thy beloved Son accomplished during the three-and-thirty years of his life on earth, and in union with his fastings, his watchings, and his prayers, I offer thee this my penance and my prayer. Look, therefore, O most loving Father, on me thy most bounden debtor, now prostrate at thy feet, desiring to make thee adequate satisfaction and reparation for all the insults and injuries I have done thee; and grant me strength and grace to say this prayer according to thy most holy will. Amen.

O MOST holy Father, I offer thee this my confession and my satisfaction in union with all the acts of penance which have ever been done to the glory of thy holy Name; beseeching thee that thou wouldst vouchsafe to accept it, and to render it availing through the merits of the passion of thy beloved Son, and through the intercession of the ever-blessed Virgin Mary, of all thy holy Apostles, Martyrs, Confessors, and Virgins. Whatever has been lacking to me in sincere and earnest preparation, in perfect contrition, in frank and clear confession, I commend to the sweetest Heart of thine only-begotten Son, that treasury of all good and of all grace, from whose overflowing abundance all debts to thee are fully acquitted; that through it all my negligences and defects in the reception of this holy Sacrament may be fully and perfectly supplied to thine everlasting praise and glory, and that thou mayest effectually absolve me in heaven, even as thy minister has with thy authority absolved me here on earth: through Jesus Christ our Lord, who liveth and reigneth with thee and the Holy Ghost, ever world without end. Amen.
