17. The blessed Apostle also perfectly describes this mystery of the ineffable birth of Christ’s body in the words, The first man was from the soil of the ground, the second man from heaven613 1 Cor. xv. 47. One copy reads de terra terrenus, of the earth, earth.. Calling Him ‘Man’ he expresses His birth from the Virgin, who in the exercise of her office as mother, performed the duties of her sex in the conception and birth of man. And when he says, The second man from heaven he testifies His origin from the Holy Ghost, Who came upon the Virgin614 Luke i. 35. “The Holy Ghost shall come upon thee, and the power of the Most High shall overshadow thee.”. As He is then man, and from heaven, this Man was born of the Virgin, and conceived of the Holy Ghost. So speaks the Apostle.
17. De terra est, ut ex Virgine; ut ex Verbo, de coelo.---Absolute autem beatus Apostolus etiam hujus inenarrandae corporeae nativitatis sacramentum locutus est, dicens: Primus homo de terrae limo, secundus homo de coelo (I Cor. XV, 47). Hominem enim dicens, nativitatem ex Virgine docuit: quae officio usa materno, sexus sui naturam in conceptu et partu hominis exsecuta est. Et cum ait secundum hominem de coelo, originem ejus ex supervenientis in Virginem sancti Spiritus aditu testatus est; atque ita cum et homo est, et de coelis est; hominis hujus et partus a Virgine est, et conceptus ex Spiritu est. Et haec quidem Apostolus ait.
