12.17.26   It yet remains for a man to say, if he will, that "the already perfected and formed natures, visible and invisible, are not signified under the name of heaven and earth, when we read, In the beginning God made heaven and earth, but that the yet unformed commencement of things, the stuff apt to receive form and making, was called by these names, because therein were confusedly contained, not as yet distinguished by their qualities and forms, all those things which being now digested into order, are called Heaven and Earth, the one being the spiritual, the other the corporeal, creation."
