Whether one angel speaks to another?

❌ Objection 1 : It would seem that one angel does not speak to another. For Gregory says (Moral. xviii) that, in the state of the resurrection "each one's body will not hide his mind from his fellows." Much less, therefore, is one angel's mind hidden from another. But speech manifests to another what lies hidden in the mind. Therefore it is not necessary that one angel should speak to another.

❌ Objection 2 : Further, speech is twofold; interior, whereby one speaks to oneself; and exterior, whereby one speaks to another. But exterior speech takes place by some sensible sign, as by voice, or gesture, or some bodily member, as the tongue, or the fingers, and this cannot apply to the angels. Therefore one angel does not speak to another.

❌ Objection 3 : Further, the speaker incites the hearer to listen to what he says. But it does not appear that one angel incites another to listen; for this happens among us by some sensible sign. Therefore one angel does not speak to another.
