John Chrysostom
"As is the earthy, such also are the earthy"; they likewise perish and die. And, "as is the heavenly, such also are the heavenly"; they likewise remain immortal and radiant (1 Cor 15:48).
But did not the latter also die? He died, yet He not only suffered no harm from it, but by this very means destroyed death.
Do you see how here the Apostle confirms the teaching on the resurrection by death itself? When there is, as I said before, a firstfruit and a head, do not doubt concerning the whole body.
Moreover, here he offers an excellent exhortation to virtuous life. He sets forth models both of the lofty and philosophical life and of its opposite, and points to the firstfruits of each: the first in Christ, the second in Adam.
Therefore he did not simply say, from the earth, but "earthy," that is, fleshly and attached to the present.
