Prayer from the Raccolta (favored by Pope Pius IX)
O Eternal God, Creator of all things, remember that the souls of infidels have been created by Thee out of nothing, and formed after Thine image and likeness.
Behold, O Lord, to the dishonour of Thy name, Hell is being filled with these souls. Remember that Jesus Christ, Thy only Son, for their salvation suffered a most cruel death.
Do not permit, O Lord, I beseech Thee, that Thy Divine Son be any longer despised by infidels but rather, being appeased by the prayers of Thy Saints and of the Church, the most holy Spouse of Thy Son, vouchsafe to be mindful of Thy mercy; and forgetting their idolatry and their infidelity, bring them also to know Him whom Thou didst send, Jesus Christ, Thy Son, Our Lord, Who is our health, life and resurrection, through Whom we have been saved and redeemed to whom be all glory forever.
