ode of knowledge.

Reply Obj. 2: The Master's words are not to be understood as if the
inferior angels were entirely ignorant of the Mystery of the
Incarnation but that they did not know it as fully as the superior
angels; and that they progressed in the knowledge of it afterwards
when the Mystery was accomplished.

Reply Obj. 3: Till the Judgment Day some new things are always being
revealed by God to the highest angels, concerning the course of the
world, and especially the salvation of the elect. Hence there is
always something for the superior angels to make known to the
inferior.

QUESTION 107

THE SPEECH OF THE ANGELS
(In Five Articles)

We next consider the speech of the angels. Here there are five points
of inquiry:

(1) Whether one angel speaks to another?

(2) Whether the inferior speaks to the superior?

(3) Whether an angel speaks to God?

(4) Whether the angelic speech is subject to local distance?

(5) Whether all the speech of one angel to another is known to all?

FIRST ARTICLE [I, Q. 107, Art. 1]

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.

Obj. 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.

Obj. 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.

_On the contrary,_ The Apostle says (1 Cor. 13:1): "If I speak with
the tongues of men and of angels."

_I answer that,_ The angels speak in a certain way. But, as Gregory
says (Moral. ii): "It is fitting that our mind, rising above the
properties of bodily speech, should be lifted to the sublime and
unknown methods of interior speech."
