On the contrary, It is said (Prov. 8:22), in the person of begotten Wisdom: "The Lord possessed me in the beginning of His ways, before He made anything from the beginning." But, as was shown above (A. 1), the angels were made by God. Therefore at one time the angels were not.
I answer that, God alone, Father, Son and Holy Ghost, is from eternity. Catholic Faith holds this without doubt; and everything to the contrary must be rejected as heretical. For God so produced creatures that He made them "from nothing"; that is, after they had not been.
Reply Obj. 1: God's being is His will. So the fact that God produced the angels and other creatures by His being does not exclude that He made them also by His will. But, as was shown above (Q. 19, A. 3; Q. 46, A. 1), God's will does not act by necessity in producing creatures. Therefore He produced such as He willed, and when He willed.
Reply Obj. 2: An angel is above that time which is the measure of the movement of the heavens; because he is above every movement of a corporeal nature. Nevertheless he is not above time which is the measure of the succession of his existence after his non-existence, and which is also the measure of the succession which is in his operations. Hence Augustine says (Gen. ad lit. viii, 20,21) that "God moves the spiritual creature according to time."
Reply Obj. 3: Angels and intelligent souls are incorruptible by the very fact of their having a nature whereby they are capable of truth. But they did not possess this nature from eternity; it was bestowed upon them when God Himself willed it. Consequently it does not follow that the angels existed from eternity. _______________________
THIRD ARTICLE [I, Q. 61, Art. 3]
Whether the Angels Were Created Before the Corporeal World?
Objection 1: It would seem that the angels were created before the corporeal world. For Jerome says (In Ep. ad Tit. i, 2): "Six thousand years of our time have not yet elapsed; yet how shall we measure the time, how shall we count the ages, in which the Angels, Thrones, Dominations, and the other orders served God?" Damascene also says (De Fide Orth. ii): "Some say that the angels were begotten before all creation; as Gregory the Theologian declares, He first of all devised the angelic and heavenly powers, and the devising was the making thereof."
Obj. 2: Further, the angelic nature stands midway between the Divine and the corporeal natures. But the Divine nature is from eternity; while corporeal nature is from time. Therefore the angelic nature was produced ere time was made, and after eternity.
Obj. 3: Further, the angelic nature is more remote from the corporeal nature than one corporeal nature is from another. But one corporeal nature was made before another; hence the six days of the production of things are set forth in the opening of Genesis. Much more, therefore, was the angelic nature made before every corporeal nature.
