On the present great day He is born of the Virgin, having overcome the natural order of things. He is higher than wedlock and free from defilement. It sufficed that He the preceptor of purity should shine forth gloriously, to emerge from a pure and undefiled womb. For He — is That Same, Who in the beginning did create Adam from the virgin soil, and from Adam without wedlock did bring forth for him his wife Eve. And as Adam was without wife before that he had a wife, and the first woman then was brought into the world, so likewise on the present day the Virgin without man giveth birth to That One, about Whom spake the prophet: “He — is Man, who is he that doth know Him?” The Man Christ, clearly seen by mankind, born of God, is such that womankind was needed to perfect that of mankind, so that perfectly would be born man for woman. And just as from Adam was taken woman, without impairment and without diminishing of his masculine nature, so also from woman without man was needed to bring forth a man, similar to the bringing forth of Eve, so that Adam be not extolled in that without his means woman should bring forth woman. Therefore the Virgin without cohabitation with man gave birth to God the Word, made Man, so that in equal measure it was by the same miracle to bestow equal honour to both the one and the other half — man and woman. And just as from Adam was taken woman without his diminishing, so likewise from the Virgin was taken the body (Born of Her), wherein also the Virgin did not undergo diminishing, and Her virginity did not suffer harm. Adam dwelt well and unharmed, when the rib was taken from him: and so without defilement dwelt the Virgin, when from Her was brought forth God the Word. For this sort of reason particularly the word assumed of the Virgin Her flesh and Her (corporeal) garb, so that He be not accounted innocent of the sin of Adam. Since man stung by sin had become a vessel and instrument of evil, Christ took upon Himself this receptacle of sin into His Own flesh so that, the Creator having been co-united with the body, it should thus be freed from the foulness of the enemy, and man thus be clothed in an eternal body, which be neither perished nor destroyed for all eternity. Moreover, He that is become the God-Man is born, not as ordinarily man is born — He is born as God made Man, manifest of this by His Own Divine power, since if He were born according to the general laws of nature, the Word would seem something imperfect. Therefore, He was born of the Virgin and shone forth; therefore, having been born, He preserved unharmed the virginal womb, so that the hitherto unheard of manner of the Nativity should be for us a sign of great mystery.
