or in several places, but in
only one place.

Some, however, have been deceived in this matter. For some who were
unable to go beyond the reach of their imaginations supposed the
indivisibility of the angel to be like that of a point; consequently
they thought that an angel could be only in a place which is a point.
But they were manifestly deceived, because a point is something
indivisible, yet having its situation; whereas the angel is
indivisible, and beyond the genus of quantity and situation.
Consequently there is no occasion for determining in his regard one
indivisible place as to situation: any place which is either divisible
or indivisible, great or small suffices, according as to his own
free-will he applies his power to a great or to a small body. So the
entire body to which he is applied by his power, corresponds as one
place to him.

Neither, if any angel moves the heavens, is it necessary for him to
be everywhere. First of all, because his power is applied only to
what is first moved by him. Now there is one part of the heavens in
which there is movement first of all, namely, the part to the east:
hence the Philosopher (Phys. vii, text 84) attributes the power of
the heavenly mover to the part which is in the east. Secondly,
because philosophers do not hold that one separate substance moves
all the spheres immediately. Hence it need not be everywhere.

So, then, it is evident that to be in a place appertains quite
differently to a body, to an angel, and to God. For a body is in a
place in a circumscribed fashion, since it is measured by the place.
An angel, however, is not there in a circumscribed fashion, since he
is not measured by the place, but definitively, because he is in a
place in such a manner that he is not in another. But God is neither
circumscriptively nor definitively there, because He is everywhere.

From this we can easily gather an answer to the objections: because
the entire subject to which the angelic power is immediately applied,
is reputed as one place, even though it be continuous.

THIRD ARTICLE [I, Q. 52, Art. 3]

Whether Several Angels Can Be at the Same Time in the Same Place?

Objection 1: It would seem that several angels can be at the same
time in the same place. For several bodies cannot be at the same time
in the same place, because they fill the place. But the angels do not
fill a place, because only a body fills a place, so that it be not
