If the flesh be the old man, when did it become so? From the beginning? But Adam was wholly a new man, and of that new man there could be no part an old man. And from that time, ever since the blessing which was pronounced upon man’s generation, the flesh and the soul have had a simultaneous birth, without any calculable difference in time; so that the two have been even generated together in the womb, as we have shown in our Treatise on the Soul.
Tertullian
On the Resurrection of the Flesh
Chapter XLV
