5 They conceive, then, of three kinds of men, spiritual, material, and animal, represented by Cain, Abel, and Seth. These three natures are no longer found in one person, but constitute various kinds [of men]. The material goes, as a matter of course, into corruption. The animal, if it make choice of the better part, finds repose in the intermediate place; but if the worse, it too shall pass into destruction. But they assert that the spiritual principles which have been sown by Achamoth, being disciplined and nourished here from that time until now in righteous souls (because when given forth by her they were yet but weak), at last attaining to perfection, shall be given as brides to the angels of the Saviour, while their animal souls of necessity rest for ever with the Demiurge in the intermediate place. And again subdividing the animal souls themselves, they say that some are by nature good, and others by nature evil. The good are those who become capable of receiving the [spiritual] seed; the evil by nature are those who are never able to receive that seed.
