O Jesus, great High Priest of the new and eternal Testament, who sittest at the right hand of the Father as our perpetual Advocate and who art pleased to abide here below all days from age to age with Thy beloved Spouse the Church, and with Thy Vicar who governs it, Thou, O divine Prince of the pastors of Thy flock, hast deigned to glorify upon the seat of Peter Thy servant and Pontiff Eugene, and in the midst of the wickedness of his times to make him a model for us, meek under the assaults of his enemies, invincible in his defence of the faith, a kindly father and a avigilant teacher in his pastoral office; oh! through his merits, which are Thy grace and glory, lend a gracious ear to his intercession with Thee and hear our prayer. May Thy kingdom come, O immortal King of Ages; may Thy truth reach the ends of the earth, that truth which Thou didst bring down to us from Heaven, and may it enkindle in all hearts that fire which Thou desirest should be enkindled upon the earth. This is the earnest desire which constrains the paternal heart of Thy Vicar; a desire for reconciliation between Thee and men; a desire for truth and goodness in the souls of men; a desire to comfort the tears of so many mothers and so many children, a desire for concord and forgiveness among the nations of the earth, a desire for justice and peace. Enlighten Thy Vicar dear Jesus, consol him in his sorrows and in his universal solicitude; renew in him the spirit of the holy Pontiff, who intercedes for him before Thee. Speak, O Lord, that powerful word that will transform the spirits of men; change hatred into love; restrain the fury of human passions; assuage the sufferings and dry the tears of the unfortunate; give an increase of virtue and mutual resignation in families; give peace to the nations and the peoples; so that the Church, founded by Thee upon the rock that is Peter in order to unite all mankind around Thy altar of life and salvation, may invoke Thee in tranquility, may worship Thee and exalt Thee for ever and ever. Amen.
