...........quote///CHRIST proceeded forth from the Virgin Mary,
as Adam had from the earth: Adam by the inbreathing of the Spirit of God—And breathed into him the breath of life;—and Christ by the coming of the
Holy Spirit—the Holy Spirit shall come upon thee—was said of the Virgin Mary. Thus Christ came forth according to the likeness of Adam (Gen 2:7;
But Christ also proceeded forth accordingly to the likeness of Eve: thus Eve came forth from a father without a mother ("from the rib"),
so Christ came forth from a mother without a father (she "knew not a husband").
Just as the first Adam brought forth from Eve without the participation of a woman,
so Mary brought forth Christ without the participation of a man.
Eve appeared only by the "seed" of a man,
and Christ appeared only by the "seed" of a woman.
The means whereby Eve and Christ came into being are identical: both received human nature by the power of God from one sex.
At first the woman (Eve) did so from a man,
and thereafter the man (Christ) did so from a woman.
Thus Christ received the nature of the first Adam,
the nature of all mankind,
or the whole Adam from Mary,
who gave Him this nature of Adam.
For this reason as Adam said of Eve so can we say of Mary, and through her even of Christ: This is now bone of my bones, and flesh of my flesh.
Through the Virgin Mary our nature exists in Christ, the Second Adam (Genesis 2:21, 23; Luke 1:34).
This is alot of info to copy down here..(i know its copy and paste .....but others get upset if its too long,....and I can see their point)
But to understand the meaning behind the Genesis 3:15 you do have to read the explanation it gives us......
