Whether the inferior angel speaks to the superior?

Objections

Objection 1 : It would seem that the inferior angel does not speak to the superior. For on the text (1 Cor. 13:1), "If I speak with the tongues of men and of angels," a gloss remarks that the speech of the angels is an enlightenment whereby the superior enlightens the inferior. But the inferior never enlightens the superior, as was above explained (Question [106], Article [3]). Therefore neither do the inferior speak to the superior.
Objection 2 : Further, as was said above (Question [106], Article [1]), to enlighten means merely to acquaint one man of what is known to another; and this is to speak. Therefore to speak and to enlighten are the same; so the same conclusion follows.
Objection 3 : Further, Gregory says (Moral. ii): "God speaks to the angels by the very fact that He shows to their hearts His hidden and invisible things." But this is to enlighten them. Therefore, whenever God speaks, He enlightens. In the same way every angelic speech is an enlightening. Therefore an inferior angel can in no way speak to a superior angel.
