Whether angels can work miracles?

Objections

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."
Objection 2 : Further, Augustine says (Questions. 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.
Objection 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.
Objection 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.
