Thomas Aquinas - Summa Theologica, Part I (Prima Pars)

Reply Obj. 1: All that Damascene says refers to providence; which is the source of the signification of the name "God."

Reply Obj. 2: We can name a thing according to the knowledge we have of its nature from its properties and effects. Hence because we can know what stone is in itself from its property, this name "stone" signifies the nature of the stone itself; for it signifies the definition of stone, by which we know what it is, for the idea which the name signifies is the definition, as is said in Metaph. iv. Now from the divine effects we cannot know the divine nature in itself, so as to know what it is; but only by way of eminence, and by way of causality, and of negation as stated above (Q. 12, A. 12). Thus the name "God" signifies the divine nature, for this name was imposed to signify something existing above all things, the principle of all things and removed from all things; for those who name God intend to signify all this. _______________________

NINTH ARTICLE [I, Q. 13, Art. 9]

Whether This Name "God" Is Communicable?

Objection 1: It seems that this name "God" is communicable. For whosoever shares in the thing signified by a name shares in the name itself. But this name "God" signifies the divine nature, which is communicable to others, according to the words, "He hath given us great [Vulg.: 'most great'] and precious promises, that by these we [Vulg.: 'ye'] may be made partakers of the divine nature" (2 Pet. 1:4). Therefore this name "God" can be communicated to others.

Obj. 2: Further, only proper names are not communicable. Now this name "God" is not a proper, but an appellative noun; which appears from the fact that it has a plural, according to the text, "I have said, You are gods" (Ps. 81:6). Therefore this name "God" is communicable.

Obj. 3: Further, this name "God" comes from operation, as explained.

But other names given to God from His operations or effects are

communicable; as "good," "wise," and the like. Therefore this name

"God" is communicable.

On the contrary, It is written: "They gave the incommunicable name to wood and stones" (Wis. 14:21), in reference to the divine name. Therefore this name "God" is incommunicable.

I answer that, A name is communicable in two ways: properly, and by similitude. It is properly communicable in the sense that its whole signification can be given to many; by similitude it is communicable according to some part of the signification of the name. 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; whereas the nature of the sun is not common to many in reality, but only in idea; for the nature of the sun can be understood as existing in many subjects; and the reason is because the mind understands the nature of every species by abstraction from the singular. 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; for the plurality of this individual thing cannot be; nor can it be conceived in idea. Hence no name signifying any individual thing is properly communicable to many, but only by way of similitude; as for instance a person can be called "Achilles" metaphorically, forasmuch as he may possess something of the properties of Achilles, such as strength. On the other hand, forms which are individualized not by any suppositum, but by and of themselves, as being subsisting forms, if understood as they are in themselves, could not be communicable either in reality or in idea; but only perhaps by way of similitude, as was said of individuals. Forasmuch as we are unable to understand simple self-subsisting forms as they really are, we understand them as compound things having forms in matter; therefore, as was said in the first article, we give them concrete names signifying a nature existing in some suppositum. Hence, so far as concerns images, the same rules apply to names we impose to signify the nature of compound things as to names given to us to signify simple subsisting natures.

Since, then, this name "God" is given to signify the divine nature as stated above (A. 8), and since the divine nature cannot be multiplied as shown above (Q. 11, A. 3), it follows that this name "God" is incommunicable in reality, but communicable in opinion; just in the same way as this name "sun" would be communicable according to the opinion of those who say there are many suns. Therefore, it is written: "You served them who by nature are not gods," (Gal. 4:8), and a gloss adds, "Gods not in nature, but in human opinion." Nevertheless this name "God" is communicable, not in its whole signification, but in some part of it by way of similitude; so that those are called gods who share in divinity by likeness, according to the text, "I have said, You are gods" (Ps. 81:6).

But if any name were given to signify God not as to His nature but as to His suppositum, accordingly as He is considered as "this something," that name would be absolutely incommunicable; as, for instance, perhaps the Tetragrammaton among the Hebrew; and this is like giving a name to the sun as signifying this individual thing.

Reply Obj. 1: The divine nature is only communicable according to the participation of some similitude.

Reply Obj. 2: This name "God" is an appellative name, and not a proper name, for it signifies the divine nature in the possessor; although God Himself in reality is neither universal nor particular. For names do not follow upon the mode of being in things, but upon the mode of being as it is in our mind. And yet it is incommunicable according to the truth of the thing, as was said above concerning the name "sun."

Reply Obj. 3: These names "good," "wise," and the like, are imposed from the perfections proceeding from God to creatures; but they do not signify the divine nature, but rather signify the perfections themselves absolutely; and therefore they are in truth communicable to many. But this name "God" is given to God from His own proper operation, which we experience continually, to signify the divine nature. _______________________

TENTH ARTICLE [I, Q. 13, Art. 10]

Whether This Name "God" Is Applied to God Univocally by Nature, by Participation, and According to Opinion?

Objection 1: It seems that this name "God" is applied to God univocally by nature, by participation, and according to opinion. For where a diverse signification exists, there is no contradiction of affirmation and negation; for equivocation prevents contradiction. But a Catholic who says: "An idol is not God," contradicts a pagan who says: "An idol is God." Therefore "God" in both senses is spoken of univocally.

Obj. 2: Further, as an idol is God in opinion, and not in truth, so the enjoyment of carnal pleasures is called happiness in opinion, and not in truth. But this name "beatitude" is applied univocally to this supposed happiness, and also to true happiness. Therefore also this name "God" is applied univocally to the true God, and to God also in opinion.

Obj. 3: Further, names are called univocal because they contain one idea. Now when a Catholic says: "There is one God," he understands by the name God an omnipotent being, and one venerated above all; while the heathen understands the same when he says: "An idol is God." Therefore this name "God" is applied univocally to both.
