Paul could be arguing, as later Christians did, that Adam sinned and incurred death as a punishment, passing both sin and death on to his descendants, either as some sort of genetic inheritance or contagious disease, in the case of sin, or as a punishment in the case of death. Behind this lies the idea that his descendants were seminally in Adam, and were therefore as guilty as he was. The notion of guilt for which we have no responsibility is strange, and few hold it today, but conceivably Paul did see sin as an infection which Adam let loose on the world.
