Summa Theologica I, q. 107: The Speech of the Angels
Article 4. Whether local distance influences the angelic speech?
Objection 1It would seem that local distance affects the angelic speech. For as Damascene says (De Fide Orth. i, 13): "An angel works where he is." But speech is an angelic operation. Therefore, as an angel is in a determinate place, it seems that an angel's speech is limited by the bounds of that place.
Objection 2Further, a speaker cries out on account of the distance of the hearer. But it is said of the Seraphim that "they cried one to another" (Is. 6:3). Therefore in the angelic speech local distance has some effect.
On the contraryIt is said that the rich man in hell spoke to Abraham, notwithstanding the local distance (Lk. 16:24). Much less therefore does local distance impede the speech of one angel to another.
I answer thatThe angelic speech consists in an intellectual operation, as explained above (AA[1],2,3). And the intellectual operation of an angel abstracts from the "here and now." For even our own intellectual operation takes place by abstraction from the "here and now," except accidentally on the part of the phantasms, which do not exist at all in an angel. But as regards whatever is abstracted from "here and now," neither difference of time nor local distance has any influence whatever. Hence in the angelic speech local distance is no impediment.
Reply to Objection 1The angelic speech, as above explained (A[1], ad 2), is interior; perceived, nevertheless, by another; and therefore it exists in the angel who speaks, and consequently where the angel is who speaks. But as local distance does not prevent one angel seeing another, so neither does it prevent an angel perceiving what is ordered to him on the part of another; and this is to perceive his speech.
Reply to Objection 2The cry mentioned is not a bodily voice raised by reason of the local distance; but is taken to signify the magnitude of what is said, or the intensity of the affection, according to what Gregory says (Moral. ii): "The less one desires, the less one cries out."
Article 5. Whether all the angels know what one speaks to another?
Objection 1It would seem that all the angels know what one speaks to another. For unequal local distance is the reason why all men do not know what one man says to another. But in the angelic speech local distance has no effect, as above explained (A[4]). Therefore all the angels know what one speaks to another.
Objection 2Further, all the angels have the intellectual power in common. So if the mental concept of one ordered to another is known by one, it is for the same reason known by all.
Objection 3Further, enlightenment is a kind of speech. But the enlightenment of one angel by another extends to all the angels, because, as Dionysius says (Coel. Hier. xv): "Each one of the heavenly beings communicates what he learns to the others." Therefore the speech of one angel to another extends to all.
On the contraryOne man can speak to another alone; much more can this be the case among the angels.
I answer thatAs above explained (AA[1],2), the mental concept of one angel can be perceived by another when the angel who possesses the concept refers it by his will to another. Now a thing can be ordered through some cause to one thing and not to another; consequently the concept of one (angel) may be known by one and not by another; and therefore an angel can perceive the speech of one angel to another; whereas others do not, not through the obstacle of local distance, but on account of the will so ordering, as explained above.
From this appear the replies to the first and second objections.
Reply to Objection 3Enlightenment is of those truths that emanate from the first rule of truth, which is the principle common to all the angels; and in that way all enlightenments are common to all. But speech may be of something ordered to the principle of the created will, which is proper to each angel; and in this way it is not necessary that these speeches should be common to all.
