Word of God before all time, Word made flesh at the appropriate time; maker of the sun, made under the sun; disposing all the ages from his Fathers bosom, consecrating this day from his mothers womb; remaining there, coming forth here; the creator of heaven and earth born beneath heaven on earth; wise beyond words, wisely incapable of speech [ineffabiliter sapiens, sapienter infans]; filling the world, lying in a manger; ruling the stars, sucking at a breast; so great in the form of God, so small in the form of a slave, that the greatness was not diminished by the smallness, nor the smallness overwhelmed by the greatness. (Sermon 187, 1; PL 38, 1001)
