Prayer of Saint Ambrose
O God, I who presume to invoke Thy Holy Name, stand in the presence of Thy Divine Majesty: have mercy upon me, a man: a sinner smeared by the foulness of inherent impurity; forgive the unworthy priest in whose hand this oblation is seen offered: Spare O Lord one polluted by sins: in faults the foremost, in comparison to all others, and do not enter into judgment with Thy servant, for no one living is justified in Thy sight. It is true that we are weighed down in the faults and desires of our flesh: remember, O Lord, that we are flesh and there is no other source of help than Thee. Yeah, in Thy sight not even those in Heaven are much more cleansed than we earthly humans, of whom, as the Prophet said of all our righteous acts: we are in comparison as unworthy as a menstrual rag. O Jesus Christ, let us live. O Thou Who dost not will the death of a sinner: grant forgiveness unto us whom Thou hast established in flesh, so that by penitential acts we may come to enjoy eternal life in the Heavens, through our Lord Jesus Christ Who reigneth with Thee and the Holy Spirit throughout all ages of ages. Amen.
From the Lorrha ("Stowe") Missal used by Churches of Ireland, Scotland, Britain, France, Germany, Switzerland, and northern Italy.
