If, however, they maintain that the shadow spoken of does not exist as being produced by the shade of [those above], but simply in this respect, that [the things below] are far separated from those [above], they will then charge the light of their Father with weakness and insufficiency, as if it cannot extend so far as these things, but fails to fill that which is empty, and to dispel the shadow, and that when no one is offering any hindrance. For, according to them, the light of their Father will be changed into darkness and buried in obscurity, and will come to an end in those places which are characterized by emptiness, since it cannot penetrate and fill all things. Let them then no longer declare that their Bythus is the fulness of all things, if indeed he has neither filled nor illuminated that which is vacuum and shadow; or, on the other hand, let them cease talking of vacuum and shadow, if the light of their Father does in truth fill all things.
