From here:
The Word of the Father, through which time was made, became flesh and made his birthday in time, and willed a single day for his human birth, he without whose divine permission no day rolls round. With the Father he precedes all the spaces of ages; born this day of a mother, he inserted himself into the courses of the years.The maker of man was made man [homo factus hominis factor]so thatthe ruler of the stars might suck at breasts,bread might hunger,the fountain might thirst,light might sleep,the way might be wearied by a journey,truth might be accused by false witnesses,the judge of the living and the dead might be judged by a mortal judge,justice might be condemned by the unjust,discipline might be beaten with whips,the cluster of grapes might be crowned with thorns,the foundation might be hung from a tree,strength might be weakened,health [salus] might be wounded,life might die.He suffered these and like indignities [indigna] for us so that he might free the unworthy [indignos]. He who did no evil suffered such great evils for our sakes, while we who deserved nothing good through him have received such great goods. For the sake of all this, he who was the Son of God before all the ages, without a beginning of days, deigned to be a son of man in the last days, and the One who was born, not made, of the Father was made in the mother whom he had made, so that he might exist here and now, made from the mother, from the woman who except for him would never ever herself have been able to exist.”
(Sermon 191, 1; PL 38, 1010)
“…Man’s maker was made man that he, ruler of the Milky Way, might nurse at his mother’s breasts” is the translation quoted by Gary Wills in What the Gospels Meant (p.64).
