“My mouth shall speak the praise of the Lord, of that Lord by whom all things were made and who was made flesh amid all the works of His hands; who is the Manifestor of His Father, the Creator of His mother; Son of God born of the Father without a mother, Son of Man born of a mother without a father; the great Day of the angels, small in the day of men; the Word as God existing before all time, the Word as flesh existing only for an allotted time; the Creator of the sun created under the light of the sun; ordering all ages from the bosom of of His Father, from the womb of His mother consecrating this day; remaining there, yet proceeding hither; Maker of heaven and earth brought forth on this earth overshadowed by the heavens; unspeakably wise, wisely speechless; filling the whole world, lying in a manger; guiding the stars, a nursling at the breast; though insignificant in the form of man, so great in the form of God that His greatness was not lessened by His insignificance nor was His smallness crushed by His might.
When He assumed human form He did not abandon His divine operations, nor did He cease to reach from end to end mightily and to order all things sweetly.
When clothed in the weakness of our flesh He was received, not imprisoned, in the Virgin’s womb so that without the food of wisdom being withdrawn from the angels we might taste how sweet is the Lord.”
