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

miracle is required that it be against the order of the whole created

nature. But God alone can do this, because, whatever an angel or any

other creature does by its own power, is according to the order of

created nature; and thus it is not a miracle. Hence God alone can

work miracles.

Reply Obj. 1: Some angels are said to work miracles; either because

God works miracles at their request, in the same way as holy men are

said to work miracles; or because they exercise a kind of ministry in

the miracles which take place; as in collecting the dust in the

general resurrection, or by doing something of that kind.

Reply Obj. 2: Properly speaking, as said above, miracles are those

things which are done outside the order of the whole created nature.

But as we do not know all the power of created nature, it follows

that when anything is done outside the order of created nature by a

power unknown to us, it is called a miracle as regards ourselves. So

when the demons do anything of their own natural power, these things

are called "miracles" not in an absolute sense, but in reference to

ourselves. In this way the magicians work miracles through the

demons; and these are said to be done by "private contracts,"

forasmuch as every power of the creature, in the universe, may be

compared to the power of a private person in a city. Hence when a

magician does anything by compact with the devil, this is done as it

were by private contract. On the other hand, the Divine justice is in

the whole universe as the public law is in the city. Therefore good

Christians, so far as they work miracles by Divine justice, are said

to work miracles by "public justice": but bad Christians by the

"signs of public justice," as by invoking the name of Christ, or by

making use of other sacred signs.

Reply Obj. 3: Spiritual powers are able to effect whatever happens in

this visible world, by employing corporeal seeds by local movement.

Reply Obj. 4: Although the angels can do something which is outside

the order of corporeal nature, yet they cannot do anything outside

the whole created order, which is essential to a miracle, as above

explained.
