From the letter to the Corinthians by Saint Clement I, pope
The Word of God on high, fountain of wisdom
For his chosen ones scattered throughout the world, we shall make our constant prayer to the Creator of the universe. May he allow none of them to fall away, but preserve them all through his beloved Son, Jesus Christ, through whom he called us out of darkness into light, out of ignorance to the knowledge of his glorious name.
Give us grace, Lord, to hope in your Name, to which all creatures owe their being. Open the eyes of our heart to know you alone, the Most High in the highest heavens, the holy One, whose dwelling is in the holy. You abase the arrogance of the proud, frustrate the designs of the godless, exalt the lowly and humble the lofty. You give men wealth and take it away; you slay them, save them and give them new life. Alone the Benefactor of spirits and God of all flesh, your gaze penetrates the depths, you observe the doings of men. Helper of those in peril, Savior of those in despair, you created and still keep watch over all that draws breath. You cause the peoples on the earth to multiply, and from them all choose those who love you through Jesus Christ, your beloved Son. Through him you have instructed us, sanctified us, honored us.
Lord, we entreat you to help us. Come to the aid of the afflicted, pity the lowly, raise up the fallen, show your face to the needy, heal the sick, convert the wayward, feed the hungry, deliver the captives, support the weak, encourage the fainthearted. Let all nations know that you alone are God; Jesus Christ is your Son, and we are your people and the sheep of your pasture.
Lord, you created the world according to the eternal decree now revealed in your works. Faithful throughout all generations, you are just in judgment, wonderful in power and majesty. You formed your creation with wisdom, established it with prudence. Everything we see proclaims your goodness. You are kind and compassionate, and never fail those who put their trust in you. Forgive us for our failings and for our sins.
Do not hold all the transgressions of your servants against them, but purify us by your truth, and so guide our footsteps that by walking in holiness and justice and simplicity of heart we may do what is good and pleasing in your sight and in the sight of our leaders.
Lord, let the light of your face shine upon us, so that we may enjoy your blessings in peace, protected by your strong hand, and freed from all sin by your outstretched arm; and deliver us from those who hate us unjustly.
Give peace and concord to us and to all mankind, even as you gave it to our ancestors when they devoutly called upon you in faith and truth. Lord, you alone are able to bestow these and even greater benefits upon us. We praise you through Jesus Christ, our high priest and the champion of our souls. Through him be glory and majesty to you now and throughout all generations, for ever and ever. Amen.
