Whether the empyrean heaven was created at the same time as formless matter?

Objections

Objection 1 : It would seem that the empyrean heaven was not created at the same time as formless matter. For the empyrean, if it is anything at all, must be a sensible body. But all sensible bodies are movable, and the empyrean heaven is not movable. For if it were so, its movement would be ascertained by the movement of some visible body, which is not the case. The empyrean heaven, then, was not created contemporaneously with formless matter.
Objection 2 : Further, Augustine says (De Trin. iii, 4) that "the lower bodies are governed by the higher in a certain order." If, therefore, the empyrean heaven is the highest of bodies, it must necessarily exercise some influence on bodies below it. But this does not seem to be the case, especially as it is presumed to be without movement; for one body cannot move another unless itself also be moved. Therefore the empyrean heaven was not created together with formless matter.
Objection 3 : Further, if it is held that the empyrean heaven is the place of contemplation, and not ordained to natural effects; on the contrary, Augustine says (De Trin. iv, 20): "In so far as we mentally apprehend eternal things, so far are we not of this world"; from which it is clear that contemplation lifts the mind above the things of this world. Corporeal place, therefore, cannot be the seat of contemplation.
Objection 4 : Further, among the heavenly bodies exists a body, partly transparent and partly luminous, which we call the sidereal heaven. There exists also a heaven wholly transparent, called by some the aqueous or crystalline heaven. If, then, there exists a still higher heaven, it must be wholly luminous. But this cannot be, for then the air would be constantly illuminated, and there would be no night. Therefore the empyrean heaven was not created together with formless matter.
