Whether heavenly bodies can act on the demons?

❌ Objection 1 : It would seem that heavenly bodies can act on the demons. For the demons, according to certain phases of the moon, can harass men, who on that account are called lunatics, as appears from Mt. 4:24 and 17:14. But this would not be if they were not subject to the heavenly bodies. Therefore the demons are subject to them.

❌ Objection 2 : Further, necromancers observe certain constellations in order to invoke the demons. But these would not be invoked through the heavenly bodies unless they were subject to them. Therefore they are subject to them.

❌ Objection 3 : Further, heavenly bodies are more powerful than inferior bodies. But the demons are confined to certain inferior bodies, namely, "herbs, stones, animals, and to certain sounds and words, forms and figures," as Porphyry says, quoted by Augustine (De Civ. Dei x, 11). Much more therefore are the demons subject to the action of heavenly bodies.
