SUMMA THEOLOGICA. Thomas Aquinas
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 to Objection 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, but from the seed of men taken for the purpose; as when the demon assumes first the form of a woman, and afterwards of a man; just as they take the seed of other things for other generating purposes, as Augustine says (De Trin. iii), so that the person born is not the child of a demon, but of a man.
OF THE ANGELS IN RELATION TO PLACE (THREE ARTICLES)
We now inquire into the place of the angels. Touching this there are three subjects of inquiry:
(1) Is the angel in a place?
(2) Can he be in several places at once?
(3) Can several angels be in the same place?
Whether an angel is in a place?
Objection 1: It would seem that an angel is not in a place. For Boethius says (De Hebdom.): "The common opinion of the learned is that things incorporeal are not in a place." And again, Aristotle observes (Phys. iv, text 48,57) that "it is not everything existing which is in a place, but only a movable body." But an angel is not a body, as was shown above ( Question [50]). Therefore an angel is not in a place.
Objection 2: Further, place is a "quantity having position." But everything which is in a place has some position. Now to have a position cannot benefit an angel, since his substance is devoid of quantity, the proper difference of which is to have a position. Therefore an angel is not in a place.
Objection 3: Further, to be in a place is to be measured and to be contained by such place, as is evident from the Philosopher (Phys. iv, text 14,119). But an angel can neither be measured nor contained by a place, because the container is more formal than the contained; as air with regard to water (Phys. iv, text 35,49). Therefore an angel is not in a place.
On the contrary, It is said in the Collect [*Prayer at Compline, Dominican Breviary]: "Let Thy holy angels who dwell herein, keep us in peace."
I answer that, It is befitting an angel to be in a place; yet an angel and a body are said to be in a place in quite a different sense. A body is said to be in a place in such a way that it is applied to such place according to the contact of dimensive quantity; but there is no such quantity in the angels, for theirs is a virtual one. Consequently an angel is said to be in a corporeal place by application of the angelic power in any manner whatever to any place.
Accordingly there is no need for saying that an angel can be deemed commensurate with a place, or that he occupies a space in the continuous; for this is proper to a located body which is endowed with dimensive quantity. In similar fashion it is not necessary on this account for the angel to be contained by a place; because an incorporeal substance virtually contains the thing with which it comes into contact, and is not contained by it: for the soul is in the body as containing it, not as contained by it. In the same way an angel is said to be in a place which is corporeal, not as the thing contained, but as somehow containing it.
And hereby we have the answers to the objections.
Whether an angel can be in several places at once?
Objection 1: It would seem that an angel can be in several places at once. For an angel is not less endowed with power than the soul. But the soul is in several places at once, for it is entirely in every part of the body, as Augustine says (De Trin. vi). Therefore an angel can be in several places at once.
Objection 2: Further, an angel is in the body which he assumes; and, since the body which he assumes is continuous, it would appear that he is in every part thereof. But according to the various parts there are various places. Therefore the angel is at one time in various places.
Objection 3: Further, Damascene says (De Fide Orth. ii) that "where the angel operates, there he is." But occasionally he operates in several places at one time, as is evident from the angel destroying Sodom (Gn. 19:25). Therefore an angel can be in several places at the one time.
On the contrary, Damascene says (De Fide Orth. ii) that "while the angels are in heaven, they are not on earth."
I answer that, An angel's power and nature are finite, whereas the Divine power and essence, which is the universal cause of all things, is infinite: consequently God through His power touches all things, and is not merely present in some places, but is everywhere. Now since the angel's power is finite, it does not extend to all things, but to one determined thing. For whatever is compared with one power must be compared therewith as one determined thing. Consequently since all being is compared as one thing to God's universal power, so is one particular being compared as one with the angelic power. Hence, since the angel is in a place by the application of his power to the place, it follows that he is not everywhere, nor 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,
