Apostolic Constitutions, Book VII 33

1Our eternal Saviour, the King of gods, who alone art almighty, and the Lord, the God of all beings, and the God of our holy and blameless fathers, and of those before us; the God of Abraham, and of Isaac, and of Jacob; who art merciful and compassionate, long-suffering, and abundant in mercy; to whom every heart is naked, and by whom every heart is seen, and to whom every secret thought is revealed: to You do the souls of the righteous cry aloud, upon You do the hopes of the godly trust, You Father of the blameless, You hearer of the supplication of those that call upon You with uprightness, and who know the supplications that are not uttered: for Your providence reaches as far as the inmost parts of mankind; and by Your knowledge You search the thoughts of every one, and in every region of the whole earth the incense of prayer and supplication is sent up to You. O You who hast appointed this present world as a place of combat to righteousness, and hast opened to all the gate of mercy, and hast demonstrated to every man by implanted knowledge, and natural judgment, and the admonitions of the law, how the possession of riches is not everlasting, the ornament of beauty is not perpetual, our strength and force are easily dissolved; and that all is vapour and vanity; and that only the good conscience of faith unfeigned passes through the midst of the heavens, and returning with truth, takes hold of the right hand of the joy which is to come. And withal, before the promise of the restoration of all things is accomplished, the soul itself exults in hope, and is joyful. For from that truth which was in our forefather Abraham, when he changed his way You guided him by a vision, and taught him what kind of state this world is; and knowledge went before his faith, and faith was the consequence of his knowledge; and the covenant did follow after his faith. For You said: I will make your seed as the stars of heaven, and as the sand which is by the seashore. Moreover, when You had given him Isaac, and knew him to be like him in his mode of life, You were then called his God, saying: I will be a God to you, and to your seed after you. And when our father Jacob was sent into Mesopotamia, You showed him Christ, and by him speak, saying: Behold, I am with you, and I will increase you, and multiply you exceedingly. And so You spoke to Moses, Your faithful and holy servant, at the vision of the bush: I am He that is; this is my name for ever, and my memorial for generations of generations. O You great protector of the posterity of Abraham, You are blessed forever.
