On the Soul (Anima)
1 The order of our arrangement now requires us, after the discussion of the preceding subjects, to institute a general inquiry regarding the soul; and, beginning with points of inferior importance, to ascend to those that are of greater. Now, that there are souls in all living things, even in those which live in the waters, is, I suppose, doubted by no one. For the general opinion of all men maintains this; and confirmation from the authority of holy Scripture is added, when it is said that “God made great whales, and every living creature that moves which the waters brought forth after their kind.” It is confirmed also from the common intelligence of reason, by those who lay down in certain words a definition of soul. For soul is defined as follows: a substance φανταστική and ὁρμητική, which may be rendered into Latin, although not so appropriately, sensibilis et mobilis. This certainly may be said appropriately of all living beings, even of those which abide in the waters; and of winged creatures too, this same definition of animamay be shown to hold good. Scripture also has added its authority to a second opinion, when it says, “You shall not eat the blood, because the life of all flesh is its blood; and you shall not eat the life with the flesh;” in which it intimates most clearly that the blood of every animal is its life. And if any one now were to ask how it can be said with respect to bees, wasps, and ants, and those other things which are in the waters, oysters and cockles, and all others which are without blood, and are most clearly shown to be living things, that the “life of all flesh is the blood,” we must answer, that in living things of that sort the force which is exerted in other animals by the power of red blood is exerted in them by that liquid which is within them, although it be of a different colour; for colour is a thing of no importance, provided the substance be endowed with life. That beasts of burden or cattle of smaller size are endowed with souls, there is, by general assent, no doubt whatever. The opinion of holy Scripture, however, is manifest, when God says, “Let the earth bring forth the living creature after its kind, four-footed beasts, and creeping things, and beasts of the earth after their kind.” And now with respect to man, although no one entertains any doubt, or needs to inquire, yet holy Scripture declares that “God breathed into his countenance the breath of life, and man became a living soul.” It remains that we inquire respecting the angelic order whether they also have souls, or are souls; and also respecting the other divine and celestial powers, as well as those of an opposite kind. We nowhere, indeed, find any authority in holy Scripture for asserting that either the angels, or any other divine spirits that are ministers of God, either possess souls or are called souls, and yet they are felt by very many persons to be endowed with life. But with regard to God, we find it written as follows: “And I will put My soul upon that soul which has eaten blood, and I will root him out from among his people;” and also in another passage, “Your new moons, and sabbaths, and great days, I will not accept; your fasts, and holidays, and festal days, My soul hates.” And in the twenty-second Psalm, regarding Christ— for it is certain, as the Gospel bears witness, that this Psalm is spoken of Him— the following words occur: “O Lord, be not far from helping me; look to my defence: O God, deliver my soul from the sword, and my beloved one from the hand of the dog;” although there are also many other testimonies respecting the soul of Christ when He tabernacled in the flesh.
2. But the nature of the incarnation will render unnecessary any inquiry into the soul of Christ. For as He truly possessed flesh, so also He truly possessed a soul. It is difficult indeed both to feel and to state how that which is called in Scripture the soul of God is to be understood; for we acknowledge that nature to be simple, and without any intermixture or addition. In whatever way, however, it is to be understood, it seems, meanwhile, to be named the soul of God; whereas regarding Christ there is no doubt. And therefore there seems to me no absurdity in either understanding or asserting some such thing regarding the holy angels and the other heavenly powers, since that definition of soul appears applicable also to them. For who can rationally deny that they are “sensible and moveable?” But if that definition appear to be correct, according to which a soul is said to be a substance rationally “sensible and moveable,” the same definition would seem also to apply to angels. For what else is in them than rational feeling and motion? Now those beings who are comprehended under the same definition have undoubtedly the same substance. Paul indeed intimates that there is a kind of animal-man who, he says, cannot receive the things of the Spirit of God, but declares that the doctrine of the Holy Spirit seems to him foolish, and that he cannot understand what is to be spiritually discerned. In another passage he says it is sown an animal body, and arises a spiritual body, pointing out that in the resurrection of the just there will be nothing of an animal nature. And therefore we inquire whether there happen to be any substance which, in respect of its being anima, is imperfect. But whether it be imperfect because it falls away from perfection, or because it was so created by God, will form the subject of inquiry when each individual topic shall begin to be discussed in order. For if the animal man receive not the things of the Spirit of God, and because he is animal, is unable to admit the understanding of a better, i.e., of a divine nature, it is for this reason perhaps that Paul, wishing to teach us more plainly what that is by means of which we are able to comprehend those things which are of the Spirit, i.e., spiritual things, conjoins and associates with the Holy Spirit an understanding rather than a soul. For this, I think, he indicates when he says, “I will pray with the spirit, I will pray with the understanding also; I will sing with the spirit, I will sing with the understanding also.” And he does not say that “I will pray with the soul,” but with the spirit and the understanding. Nor does he say, “I will sing with the soul,” but with the spirit and the understanding.
