De Posteritate Caini

Again, if any person goes out from any place, that which he leaves behind him is in a different place from that in which he now is, but if this be true it must follow that there are some portions of the universe deprived of the presence of God, who never leaves any place empty or destitute of himself, but who fills up all things for all time;
