Taken from a writing of St. Peter's -
And so Christ is born that by his birth he might restore our nature. He became a child, was fed, and grew that he might inaugurate the one perfect age to remain for ever as he had created it. He supports man that man might no longer fall. And the creature he had formed of earth he now makes heavenly; and what he had endowed with a human soul he now vivifies to become a heavenly spirit. In this way he fully raised man to God, and left in him neither sin, nor death, nor travail, nor pain, nor anything earthly, with the grace of our Lord Christ Jesus, who lives and reigns with the Father in the unity of the Holy Spirit, now and for ever, for all the ages of eternity. Amen.
