he angel is
not a compound of different natures, so that the inclination of the
one thwarts or retards the tendency of the other; as happens in man,
in whom the movement of his intellective part is either retarded or
thwarted by the inclination of his sensitive part. But when there is
nothing to retard or thwart it, nature is moved with its whole energy.
So it is reasonable to suppose that the angels who had a higher
nature, were turned to God more mightily and efficaciously. The same
thing happens in men, since greater grace and glory are bestowed
according to the greater earnestness of their turning to God. Hence it
appears that the angels who had the greater natural powers, had the
more grace and glory.

Reply Obj. 1: As grace comes of God's will alone, so likewise does
the nature of the angel: and as God's will ordained nature for grace,
so did it ordain the various degrees of nature to the various degrees
of grace.

Reply Obj. 2: The acts of the rational creature are from the creature
itself; whereas nature is immediately from God. Accordingly it seems
rather that grace is bestowed according to degree of nature than
according to works.

Reply Obj. 3: Diversity of natural gifts is in one way in the angels,
who are themselves different specifically; and in quite another way
in men, who differ only numerically. For specific difference is on
account of the end; while numerical difference is because of the
matter. Furthermore, there is something in man which can thwart or
impede the movement of his intellective nature; but not in the
angels. Consequently the argument is not the same for both.

SEVENTH ARTICLE [I, Q. 62, Art. 7]

Whether Natural Knowledge and Love Remain in the Beatified Angels?

Objection 1: It would seem that natural knowledge and love do not
remain in the beatified angels. For it is said (1 Cor. 13:10): "When
that which is perfect is come, then that which is in part shall be
done away." But natural love and knowledge are imperfect in comparison
with beatified knowledge and love. Therefore, in beatitude, natural
knowledge and love cease.

Obj. 2: Further, where one suffices, another is superfluous. But the
knowledge and love of glory suffice for the beatified angels.
Therefore it would be superfluous for their natural knowledge and
love to remain.

Obj. 3: Further, the same faculty has not two simultaneous acts, as
the same line cannot, at the same end, be terminated
