Whether those miracles were fitting which Christ worked in spiritual substances?

❌ Objection 1 : It would seem that those miracles were unfitting which Christ worked in spiritual substances. For among spiritual substances the holy angels are above the demons; for, as Augustine says (De Trin. iii): "The treacherous and sinful rational spirit of life is ruled by the rational, pious, and just spirit of life." But we read of no miracles worked by Christ in the good angels. Therefore neither should He have worked miracles in the demons.

❌ Objection 2 : Further, Christ's miracles were ordained to make known His Godhead. But Christ's Godhead was not to be made known to the demons: since this would have hindered the mystery of His Passion, according to 1 Cor. 2:8: "If they had known it, they would never have crucified the Lord of glory." Therefore He should not have worked miracles in the demons.

❌ Objection 3 : Further, Christ's miracles were ordained to the glory of God: hence it is written (Mt. 9:8) that "the multitudes seeing" that the man sick of the palsy had been healed by Christ, "feared, and glorified God that gave such power to men." But the demons have no part in glorifying God; since "praise is not seemly in the mouth of a sinner" (Ecclus. 15:9). For which reason also "He suffered them not to speak" (Mk. 1:34; Lk. 4:41) those things which reflected glory on Him. Therefore it seems that it was unfitting for Him to work miracles in the demons.

❌ Objection 4 : Further, Christ's miracles are ordained to the salvation of mankind. But sometimes the casting out of demons from men was detrimental to man, in some cases to the body: thus it is related (Mk. 9:24,25) that a demon at Christ's command, "crying out and greatly tearing" the man, "went out of him; and he became as dead, so that many said: He is dead"; sometimes also to things: as when He sent the demons, at their own request, into the swine, which they cast headlong into the sea; wherefore the inhabitants of those parts "besought Him that He would depart from their coasts" (Mt. 8:31-34). Therefore it seems unfitting that He should have worked such like miracles.
