the movement of the heavenly bodies, even though they be in them as
the movers in the thing moved, because the heavenly bodies do not
change place in their entirety; nor for the spirit which moves the
world is there any fixed locality according to any restricted part of
the world's substance, which now is in the east, and now in the west,
but according to a fixed quarter; because "the moving energy is
always in the east," as stated in Phys. viii, text 84.

Reply Obj. 4: Properly speaking, the angels do not talk through their
assumed bodies; yet there is a semblance of speech, in so far as they
fashion sounds in the air like to human voices.

Reply Obj. 5: Properly speaking, the angels cannot be said to eat,
because eating involves the taking of food convertible into the
substance of the eater.

Although after the Resurrection food was not converted into the
substance of Christ's body, but resolved into pre-existing matter;
nevertheless Christ had a body of such a true nature that food could
be changed into it; hence it was a true eating. But the food taken by
angels was neither changed into the assumed body, nor was the body of
such a nature that food could be changed into it; consequently, it was
not a true eating, but figurative of spiritual eating. This is what
the angel said to Tobias: "When I was with you, I seemed indeed to eat
and to drink; but I use an invisible meat and drink" (Tob. 12:19).

Abraham offered them food, deeming them to be men, in whom,
nevertheless, he worshipped God, as God is wont to be in the
prophets, as Augustine says (De Civ. Dei xvi).

Reply Obj. 6: As Augustine says (De Civ. Dei xv): "Many persons
affirm that they have had the experience, or have heard from such as
have experienced it, that the Satyrs and Fauns, whom the common folk
call incubi, have often presented themselves before women, and have
sought and procured intercourse with them. Hence it is folly to deny
it. But God's holy angels could not fall in such fashion before the
deluge. Hence by the sons of God are to be understood the sons of
Seth, who were good; while by the daughters of men the Scripture
designates those who sprang from the race of Cain. Nor is it to be
wondered at that giants should be born of them; for they were not all
giants, albeit there were many more before than after the deluge."
Still if some are occasionally begotten from demons, it is not from
the seed of such demons, nor from their assumed bodies
