Reply Obj. 2: The angels, by causing local motion, as the first
motion, can thereby cause other movements; that is, by employing
corporeal agents to produce these effects, as a workman employs fire
to soften iron.

Reply Obj. 3: The power of an angel is not so limited as is the power
of the soul. Hence the motive power of the soul is limited to the
body united to it, which is vivified by it, and by which it can move
other things. But an angel's power is not limited to any body; hence
it can move locally bodies not joined to it.

FOURTH ARTICLE [I, Q. 110, Art. 4]

Whether Angels Can Work Miracles?

Objection 1: It would seem that the angels can work miracles. For
Gregory says (Hom. xxxiv in Evang.): "Those spirits are called virtues
by whom signs and miracles are usually done."

Obj. 2: Further, Augustine says (QQ. 83, qu. 79) that "magicians work
miracles by private contracts; good Christians by public justice, bad
Christians by the signs of public justice." But magicians work
miracles because they are "heard by the demons," as he says elsewhere
in the same work [*Cf. Liber xxi, Sentent., sent. 4: among the
supposititious works of St. Augustine]. Therefore the demons can work
miracles. Therefore much more can the good angels.

Obj. 3: Further, Augustine says in the same work [*Cf. Liber xxi,
Sentent., sent. 4: among the supposititious works of St. Augustine]
that "it is not absurd to believe that all the things we see happen
may be brought about by the lower powers that dwell in our
atmosphere." But when an effect of natural causes is produced outside
the order of the natural cause, we call it a miracle, as, for
instance, when anyone is cured of a fever without the operation of
nature. Therefore the angels and demons can work miracles.

Obj. 4: Further, superior power is not subject to the order of an
inferior cause. But corporeal nature is inferior to an angel.
Therefore an angel can work outside the order of corporeal agents;
which is to work miracles.

_On the contrary,_ It is written of God (Ps. 135:4): "Who alone doth
great wonders."

_I answer that,_ A miracle properly so called is when something is
done outside the order of nature. But it is not enough for a miracle
if something is done outside the order of any particular nature; for
otherwise anyone would perform a miracle by throwing a stone upwards,
as such a thing is outside the order of the stone's nature. So for a
