An act of perfect contrition

In the absence of access to our churches and the sacraments, here is a prayer of immense importance for the faithful in this time of trial. The prayer is reproduced in Latin with a translation and notes.

Cuius pedes lacrymis / Peccatrix irrigavit. J-J Tissot

Deus meus, ex toto corde poenitet me omnium meorum peccatorum, eaque detestor, quia peccando, non solum poenas a Te iuste statutas promeritus sum, sed præsertim quia offendi Te, summum bonum, ac dignum qui super omnia diligaris. Ideo firmiter propono, adiuvante gratia Tua, de cetero me non peccaturum peccandique occasiones proximas fugiturum. Amen.

Oh my God, from all my heart I am sorry for all my sins, and I detest them, not only because in sinning, I deserve the penalties that you have justly established, but especially because I have offended Thee, who art the greatest good, and worthy beyond all my love. Therefore I firmly purpose, with the help of Thy grace, from henceforth to sin no more and flee the next occasions of sinning. Amen.

My God, I am from the depths of my heart pained with sorrow for all my sins and I detest them; because in sinning, not only have I deserved the punishments justly instituted by Thee, but especially because I have offended Thee, the highest good and Who art worthy to be loved above all things. I firmly propose, with the help of Thy grace, henceforth to sin no more and to flee the next occasions of sinning.

Father, I have sinned against heaven, and before thee. J-J Tissot
