Tertullian,
Ante-Nicene Fathers Vol. III, Anti-Marcion…
(1885)
“ We read in so many words: [8] “The first man is of the earth, earthy; the second man is the Lord from heaven.” [9] This passage, however, has nothing to do with any difference of substance; it only contrasts with the once [10] “earthy” substance of the flesh of the first man, Adam, the “heavenly” substance of the spirit of the second man, Christ. And so entirely does the passage refer the celestial man to the spirit and not to the flesh, that those whom it compares to Him evidently become celestial—by the Spirit, of course—even in this “earthy flesh.” ”
