On the contrary, It is said (Gen. 1:1): "In the beginning God created heaven and earth." Now, this would not be true if anything had been created previously. Consequently the angels were not created before corporeal nature.
I answer that, There is a twofold opinion on this point to be found in the writings of the Fathers. The more probable one holds that the angels were created at the same time as corporeal creatures. For the angels are part of the universe: they do not constitute a universe of themselves; but both they and corporeal natures unite in constituting one universe. This stands in evidence from the relationship of creature to creature; because the mutual relationship of creatures makes up the good of the universe. But no part is perfect if separate from the whole. Consequently it is improbable that God, Whose "works are perfect," as it is said Deut. 32:4, should have created the angelic creature before other creatures. At the same time the contrary is not to be deemed erroneous; especially on account of the opinion of Gregory Nazianzen, "whose authority in Christian doctrine is of such weight that no one has ever raised objection to his teaching, as is also the case with the doctrine of Athanasius," as Jerome says.
Reply Obj. 1: Jerome is speaking according to the teaching of the Greek Fathers; all of whom hold the creation of the angels to have taken place previously to that of the corporeal world.
Reply Obj. 2: God is not a part of, but far above, the whole universe, possessing within Himself the entire perfection of the universe in a more eminent way. But an angel is a part of the universe. Hence the comparison does not hold.
Reply Obj. 3: All corporeal creatures are one in matter; while the angels do not agree with them in matter. Consequently the creation of the matter of the corporeal creature involves in a manner the creation of all things; but the creation of the angels does not involve creation of the universe.
If the contrary view be held, then in the text of Gen. 1, "In the beginning God created heaven and earth," the words, "In the beginning," must be interpreted, "In the Son," or "In the beginning of time": but not, "In the beginning, before which there was nothing," unless we say "Before which there was nothing of the nature of corporeal creatures." _______________________
FOURTH ARTICLE [I, Q. 61, Art. 4]
Whether the Angels Were Created in the Empyrean Heaven?
Objection 1: It would seem that the angels were not created in the empyrean heaven. For the angels are incorporeal substances. Now a substance which is incorporeal is not dependent upon a body for its existence; and as a consequence, neither is it for its creation. Therefore the angels were not created in any corporeal place.
Obj. 2: Further, Augustine remarks (Gen. ad lit. iii, 10), that the angels were created in the upper atmosphere: therefore not in the empyrean heaven.
