Since these things [humanity’s fallen condition; JW] required a greater help, they also obtained
something greater. It was the Word of God himself, the one who is before the ages, the invisible, the ungraspable, the incorporeal, the Principle from the Principle, the light from the light, the source of life and immortality, the imprint of the archetypal beauty, the immutable seal, the undistorted image, the definition and explanation of his Father. He approaches his own image and bears flesh because of my flesh and mingles himself with a rational soul because of my soul, purifying like by like. And in all things he becomes a human being, except sin. He was conceived by the Virgin, who was purified beforehand in both soul and flesh by the Spirit, for it was necessary that procreation be honored and that virginity be honored more. He comes forth, God with what he has assumed, one from two opposites, flesh and spirit, the one deifying and the other deified. O the new mixture! O the paradoxical blending! He who is comes into being, and the uncreated is created, and the uncontained is contained, through the intervention of the rational soul, which mediates between the divinity and the coarseness of flesh. The one who enriches becomes poor; he is made poor in my flesh, that I might be enriched through his divinity. The full one empties himself; for he empties himself of his own glory for a short time, that I may participate in his fullness. What is the wealth of his goodness? What is this mystery concerning me? I participated in the [divine] image, and I did not keep it; he participates in my flesh both to save the image and to make the flesh immortal. He shares with us a second communion, much more paradoxical than the first [the creation; JW]; then he gave us a share in what is superior, now he shares in what is inferior. This is more godlike than the first; this, to those who can understand, is more exalted....
Now welcome for me his conception and leap for joy, if not indeed like John in the womb, then like David when the ark came to rest. Be awed at the census record through which you have been recorded in heaven, and revere the birth through which you have been released from the bonds of birth, and honor little Bethlehem, which has brought you back to paradise, and bow before the manger through which you who were without reason have been fed by the Word. Know, like the ox, your owner—Isaiah exhorts you—and like the donkey know your master’s crib, whether you are among those who are pure and under the law and chew the cud of the Word and are prepared for sacrifice, or whether up to now you are among the impure and unfit for food or sacrifice and belong to the Gentiles. Run after the star, and bring gifts with the magi, gold and frankincense and myrrh, as to a king and a God and one dead for your sake. With the shepherds give glory, with the angels sing hymns, with the archangels dance. Let there be a common celebration of the heavenly and earthly powers. For I am persuaded that they rejoice and celebrate with us today, if indeed they love humankind and love God, just as David represents them ascending with Christ after his Passion as they come to meet him and exhort each other to lift up the gates.
