"From Adam three natures were begotten. The first was the irrational, which was Cain's, the second the rational and just, which was Abel"s, the third the spiritual, which was Seth's. Now that which is earthly is "according to the image", that which is psychical according to the " likeness " of God, and that which is spiritual is according to the real nature; and with reference to these three, without the other children of Adam, it was said, "This is the book of the generation of men". And because Seth was spiritual he neither tends flocks nor tills the soil but produces a child, as spiritual things do. And him, who "hoped to call upon the name of the Lord" who looked upward and whose "citizenship is in heaven - him the world does not contain". (Theodotus, Criddle Collection.)
