...the Incarnation derives from the First Principle who redeems in an all-embracing way -- for through the Word made flesh the fall of both humankind and the angels is repaired, of both those in heaven and those on earth. Furthermore, the fall of human beings is repaired in both sexes. Hence, if the cure was to be universal, it was most fitting that an angel, a woman, and a man should concur in the mystery of the Incarnation: an angel announcing, a virgin woman conceiving, and a man as the conceived offspring. And so the angel Gabriel was the herald of the eternal Father, the immaculate Virgin was the temple of the Holy Spirit, and the conceived offspring was the very person of the Word.
Thus the representatives of all three hierarchies -- divine, angelic, and human -- concurred in this way in the universal restoration, suggesting not only the Trinity of God, but also the universality of the benefit bestowed and the generosity of the supreme Redeemer.
