Origen teaches that Adam represents all men and Eve all women.

40. When he asserts that the narrative of Moses represents God most impiously, making Him into a weakling right from the beginning, and incapable of persuading even one man whom He had formed, to this also we will reply that his remark is much the same as if one were to object to the existence of evil because God has been unable to prevent even one man from committing sin in order that just one individual might be found who has had no experience of evil from the beginning. Just as in this matter those who are concerned to defend the doctrine of providence state their case at great length and with arguments of considerable cogency, so also the story of Adam and his sin will be interpreted philosophically by those who know that Adam means anthropos (man) in the Greek language, and that in what appears to be concerned with Adam Moses is speaking of the nature of man. For, as the Bible says, 'in Adam all die', and they were condemned in 'the likeness of Adam's transgression'. Here the divine Word says this not so much about an individual as of the whole race.
Moreover, in the sequence of sayings which seem to refer to one individual, the curse of Adam is shared by all men. There is also no woman to whom the curses pronounced against Eve do not apply. And the statement that the man who was cast out of the garden with the woman was clothed with 'coats of skins', which God made for those who had sinned on account of the transgression of mankind, has a certain secret and mysterious meaning, superior to the Platonic doctrine of the descent of the soul which loses its wings and is carried hither 'until it finds some firm resting-place'.
