12.17.24   For they say, "Though these things be true, yet did not Moses intend those two, when, by revelation of the Spirit, he said, In the beginning God created heaven and earth. He did not under the name of heaven, signify that spiritual or intellectual creature which always beholds the face of God; nor under the name of earth, that formless matter." "What then?" "That man of God," say they, "meant as we say, this declared he by those words." "What?" "By the name of heaven and earth would he first signify," say they, "universally and compendiously, all this visible world; so as afterwards by the enumeration of the several days, to arrange in detail, and, as it were, piece by piece, all those things, which it pleased the Holy Ghost thus to enounce. For such were that rude and carnal people to which he spake, that he thought them fit to be entrusted with the knowledge of such works of God only as were visible." They agree, however, that under the words earth invisible and without form, and that darksome deep (out of which it is subsequently shown, that all these visible things which we all know, were made and arranged during those "days") may, not incongruously, be understood of this formless first matter.
