Thomas Aquinas

“ Hence to be in one singular subject or in many is outside the idea of the nature of the species. So, given the idea of a species, it can be understood as existing in many. But the singular, from the fact that it is singular, is divided off from all others. Hence every name imposed to signify any singular thing is incommunicable both in reality and idea ”

“ I answer that, According to the preceding article, our knowledge of God is derived from the perfections which flow from Him to creatures, which perfections are in God in a more eminent way than in creatures. Now our intellect apprehends them as they are in creatures, and as it apprehends them it signifies them by names. Therefore as to the names applied to God---viz. the perfections which they signify, such as goodness, life and the like, and their mode of signification. ”

“ But no name belongs to God in the same sense that it belongs to creatures; for instance, wisdom in creatures is a quality, but not in God. Now a different genus changes an essence, since the genus is part of the definition; and the same applies to other things. Therefore whatever is said of God and of creatures is predicated equivocally.
Further, God is more distant from creatures than any creatures are from each other. But the distance of some creatures makes any univocal predication of them impossible, as in the case of those things which are not in the same genus. ”

“ But in propositions where one same thing is predicated of itself, the same rule in some way applies, inasmuch as the intellect draws to the "suppositum" what it places in the subject; and what it places in the predicate it draws to the nature of the form existing in the "suppositum"; according to the saying that "predicates are to be taken formally, and subjects materially." To this diversity in idea corresponds the plurality of predicate and subject, while the intellect signifies the identity of the thing by the composition itself. ”

“ In the same way, as said in the preceding article, all perfections existing in creatures divided and multiplied, pre-exist in God unitedly. Thus when any term expressing perfection is applied to a creature, it signifies that perfection distinct in idea from other perfections; as, for instance, by the term "wise" applied to man, we signify some perfection distinct from a man's essence, and distinct from his power and existence, and from all similar things; whereas when we apply to it God, we do not mean to signify anything distinct from His essence, or power, or existence. ”

“ For as "smiling" applied to a field means only that the field in the beauty of its flowering is like the beauty of the human smile by proportionate likeness, so the name of "lion" applied to God means only that God manifests strength in His works, as a lion in his. Thus it is clear that applied to God the signification of names can be defined only from what is said of creatures. But to other names not applied to God in a metaphorical sense, the same rule would apply if they were spoken of God as the cause only, as some have supposed. ”

“ Now it was shown above (Q [12] , AA [11] ,12) that in this life we cannot see the essence of God; but we know God from creatures as their principle, and also by way of excellence and remotion. In this way therefore He can be named by us from creatures, yet not so that the name which signifies Him expresses the divine essence in itself. Thus the name "man" expresses the essence of man in himself, since it signifies the definition of man by manifesting his essence; for the idea expressed by the name is the definition. ”

“ For instance this name "lion" is properly communicable to all things of the same nature as "lion"; by similitude it is communicable to those who participate in the nature of a lion, as for instance by courage, or strength, and those who thus participate are called lions metaphorically. To know, however, what names are properly communicable, we must consider that every form existing in the singular subject, by which it is individualized, is common to many either in reality, or in idea; as human nature is common to many in reality, and in idea ”

“ I answer that, Univocal predication is impossible between God and creatures. The reason of this is that every effect which is not an adequate result of the power of the efficient cause, receives the similitude of the agent not in its full degree, but in a measure that falls short, so that what is divided and multiplied in the effects resides in the agent simply, and in the same manner; as for example the sun by exercise of its one power produces manifold and various forms in all inferior things. ”

“ For when we name anyone god by participation, we understand by the name of god some likeness of the true God. Likewise, when we call an idol god, by this name god we understand and signify something which men think is God ”

“ Again, sometimes a relation in one extreme may be a reality, while in the other extreme it is an idea only; and this happens whenever two extremes are not of one order; as sense and science refer respectively to sensible things and to intellectual things; which, inasmuch as they are realities existing in nature, are outside the order of sensible and intellectual existence. Therefore in science and in sense a real relation exists, because they are ordered either to the knowledge or to the sensible perception of things ”

“ Neither a Catholic nor a pagan knows the very nature of God as it is in itself; but each one knows it according to some idea of causality, or excellence, or remotion (Q [12] , A [12] ) . So a pagan can take this name "God" in the same way when he says an idol is God, as the Catholic does in saying an idol is not God. But if anyone should be quite ignorant of God altogether, he could not even name Him, unless, perhaps, as we use names the meaning of which we know not.
Art. 11 - Whether this name, HE WHO IS, is the most proper name of God? ”

“ Art. 7 - Whether names which imply relation to creatures are predicated of God temporally? Objection 1: It seems that names which imply relation to creatures are not predicated of God temporally. For all such names signify the divine substance, as is universally held. Hence also Ambrose (De Fide i) that this name "Lord" is the name of power, which is the divine substance; and "Creator" signifies the action of God, which is His essence. Now the divine substance is not temporal, but eternal. ”

“ Any intellect which understands that the thing is otherwise than it is, is false. But this does not hold in the present case; because our intellect, when forming a proposition about God, does not affirm that He is composite, but that He is simple. But taken as referring to the one who understands, the proposition is false. For the mode of the intellect in understanding is different from the mode of the thing in its essence. Since it is clear that our intellect understands material things below itself in an immaterial manner ”

“ Now there are some univocal agents which agree with their effects in name and definition, as man generates man; and there are some agents which are equivocal, as the sun which causes heat, although the sun is hot only in an equivocal sense. Therefore it seems that the first agent to which all other agents are reduced, is an univocal agent: and thus what is said of God and creatures, is predicated univocally. ”

“ For if one in its idea includes another, and vice versa, then they are simultaneous by nature: as double and half, father and son, and the like. But if one in its idea includes another, and not vice versa, they are not simultaneous by nature. ”

“ Since therefore God is outside the whole order of creation, and all creatures are ordered to Him, and not conversely, it is manifest that creatures are really related to God Himself; whereas in God there is no real relation to creatures, but a relation only in idea, inasmuch as creatures are referred to Him. ”

“ Sometimes from both extremes it is an idea only, as when mutual order or habitude can only go between things in the apprehension of reason; as when we say a thing "the same as itself." For reason apprehending one thing twice regards it as two; thus it apprehends a certain habitude of a thing to itself. ”

“ Further, a thing which is one in reality and in idea, is more one than what is one in reality and many in idea. But God is supremely one. Therefore it seems that He is not one in reality and many in idea ”

“ God, however, as considered in Himself, is altogether one and simple, yet our intellect knows Him by different conceptions because it cannot see Him as He is in Himself. Nevertheless, although it understands Him under different conceptions, it knows that one and the same simple object corresponds to its conceptions. ”

“ For He is assuredly the cause of bodies in the same way as He is the cause of good things; therefore if the words "God is good," signified no more than, "God is the cause of good things," it might in like manner be said that God is a body, inasmuch as He is the cause of bodies. So also to say that He is a body implies that He is not a mere potentiality, as is primary matter. ”

“ This name "good" is the principal name of God in so far as He is a cause, but not absolutely; for existence considered absolutely comes before the idea of cause.
Reply to Objection 3: It is not necessary that all the divine names should import relation to creatures, but it suffices that they be imposed from some perfections flowing from God to creatures. ”

“ And this appears to be the case both in propositions which have an accidental predicate, and in those which have an essential predicate. For it is manifest that "man" and "white" are the same in subject, and different in idea; for the idea of man is one thing, and that of whiteness is another. The same applies when I say, "man is an animal"; since the same thing which is man is truly animal; for in the same "suppositum" there is sensible nature by reason of which he is called animal, and the rational nature by reason of which he is called man ”

“ Likewise, when it understands simple things above itself, it understands them according to its own mode, which is in a composite manner; yet not so as to understand them to be composite things. And thus our intellect is not false in forming composition in its ideas concerning God. ”

“ As therefore, to the different perfections of creatures, there corresponds one simple principle represented by different perfections of creatures in a various and manifold manner, so also to the various and multiplied conceptions of our intellect, there corresponds one altogether simple principle, according to these conceptions, imperfectly understood. ”

“ Such a view is against the philosophers, who proved many things about God, and also against what the Apostle says: "The invisible things of God are clearly seen being understood by the things that are made" (Rom. 1:20) . ”
