Isaias 51:6

1. Again, as to their malignantly asserting that if heaven is indeed the throne of God, and earth His footstool, and if it is declared that the heaven and earth shall pass away, then when these pass away the God who sitteth above must also pass away, and therefore He cannot be the God who is over all; in the first place, they are ignorant what the expression means, that heaven is [His] throne and earth [His] footstool. For they do not know what God is, but they imagine that He sits after the fashion of a man, and is contained within bounds, but does not contain. …

IX. But if our opponents say, How then is it, if the universe be not destroyed, that the Lord says that “heaven and earth shall pass away;” and the prophet, that “the heaven shall perish as smoke, and the earth shall grow old as a garment;” we answer, because it is usual for the Scriptures to call the change of the world from its present condition to a better and more glorious one, destruction; as its earlier form is lost in the change of all things to a state of greater splendour; for there is no contradiction nor absurdity in the Holy Scriptures. …

And the meaning is something of this kind. The creation itself is in the midst of its pangs, waiting for and expecting these good things whereof we have just now spoken. For “earnest expectation” ( ἀποκαραδοκία , looking out) implies expecting intensely. And so his discourse becomes more emphatic, and he personifies this whole world as the prophets also do, when they introduce the floods clapping their hands, and little hills leaping, and mountains skipping, not that we are to fancy them alive, or ascribe any reasoning power to them, but that we may learn the greatness of the blessings, so great as to reach even to things without sense also. …

8. “In the beginning God created the heaven and the earth.” If we were to wish to discover the essence of each of the beings which are offered for our contemplation, or come under our senses, we should be drawn away into long digressions, and the solution of the problem would require more words than I possess, to examine fully the matter. To spend time on such points would not prove to be to the edification of the Church. Upon the essence of the heavens we are contented with what Isaiah says, for, in simple language, he gives us sufficient idea of their nature, “The heaven was made like smoke,” that is to say, He created a subtle substance, without solidity or density, from which to form the heavens. …

24. My beloved, men who are inferior in understanding, dispute about this that I write to thee, and say: “What is the place in which the righteous shall receive a good reward; and what is the place in which are torments, in which the wicked shall receive the punishments of their works?” O man that thinkest thus, I will ask thee, and tell thou me, why is death called death, and why is Sheol called Sheol? For it is written that when Korah and his companions made a schism against Moses, the earth opened her mouth and swallowed them up, and they went down alive into Sheol . Therefore that was the mouth of Sheol that was opened in the wilderness. David also said, The wicked shall turn back to Sheol. We say that to Sheol, in which Korah and his companions were swallowed up, thither shall the wicked be turned back. …
