Because of Your Mercy
Lord God, omnipotent Father, creator of all things, you gave me a body and a soul, and created me in your image before time was. O Lord, my God, I confess my offences to you; I have sinned before you and before your angels, and my sins are as numerous as the sands on the seashore. Yet for your love have mercy on me, God, let me not perish. Do not turn your face from me since I do not seek your forgiveness because I think I deserve it, but because of your mercy. Look down on me, Lord, from the holy seat of your majesty, and illumine the shadows of my heart with the radiance of your splendor. Protect me, Lord, with the shield of your truth and faith, so that the glowing darts of the devil may not pierce me. Have mercy, Savior of the world, who live and reign for ever.
Latin - 10th century

The prayer asks forgiveness because of God’s mercy rather than any claim to deserve it. In The Name of God Is Mercy, Pope Francis speaks with Andrea Tornielli about repentance, forgiveness and the Church’s welcome to those seeking reconciliation.
