1 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 Pt. 1, 4). Therefore this name God can be communicated to others.
1 Ad nonum sic proceditur. Videtur quod hoc nomen Deus sit communicabile. Cuicumque enim communicatur res significata per nomen, communicatur et nomen ipsum. Sed hoc nomen Deus, ut dictum est, significat divinam naturam, quae est communicabilis aliis, secundum illud II Pet. I, magna et pretiosa promissa nobis donavit, ut per hoc efficiamur divinae consortes naturae. Ergo hoc nomen Deus est communicabile.
2 Objection 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.
2 Praeterea, sola nomina propria non sunt communicabilia. Sed hoc nomen Deus non est nomen proprium, sed appellativum, quod patet ex hoc quod habet plurale, secundum illud Psalmi LXXXI, ego dixi, dii estis. Ergo hoc nomen Deus est communicabile.
3 Objection 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.
3 Praeterea, hoc nomen Deus imponitur ab operatione, ut dictum est. Sed alia nomina quae imponuntur Deo ab operationibus, sive ab effectibus, sunt communicabilia, ut bonus, sapiens et huiusmodi. Ergo et hoc nomen Deus est communicabile.
4 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.
4 Sed contra est quod dicitur Sap. XIV, incommunicabile nomen lignis et lapidibus imposuerunt; et loquitur de nomine deitatis. Ergo hoc nomen Deus est nomen incommunicabile.
5 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 Article 8), and since the divine nature cannot be multiplied as shown above Question 11, Article 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.
5 Respondeo dicendum quod aliquod nomen potest esse communicabile dupliciter, uno modo, proprie; alio modo, per similitudinem. Proprie quidem communicabile est, quod secundum totam significationem nominis, est communicabile multis. Per similitudinem autem communicabile est, quod est communicabile secundum aliquid eorum quae includuntur in nominis significatione. Hoc enim nomen leo proprie communicatur omnibus illis in quibus invenitur natura quam significat hoc nomen leo, per similitudinem vero communicabile est illis qui participant aliquid leoninum, ut puta audaciam vel fortitudinem, qui metaphorice leones dicuntur.
Ad sciendum autem quae nomina proprie sunt communicabilia, considerandum est quod omnis forma in supposito singulari existens, per quod individuatur, communis est multis, vel secundum rem vel secundum rationem saltem, sicut natura humana communis est multis secundum rem et rationem, natura autem solis non est communis multis secundum rem, sed secundum rationem tantum; potest enim natura solis intelligi ut in pluribus suppositis existens. Et hoc ideo, quia intellectus intelligit naturam cuiuslibet speciei per abstractionem a singulari, unde esse in uno supposito singulari vel in pluribus, est praeter intellectum naturae speciei, unde, servato intellectu naturae speciei, potest intelligi ut in pluribus existens.
Sed singulare, ex hoc ipso quod est singulare, est divisum ab omnibus aliis. Unde omne nomen impositum ad significandum aliquod singulare, est incommunicabile et re et ratione, non enim potest nec in apprehensione cadere pluralitas huius individui. Unde nullum nomen significans aliquod individuum, est communicabile multis proprie, sed solum secundum similitudinem; sicut aliquis metaphorice potest dici Achilles, inquantum habet aliquid de proprietatibus Achillis, scilicet fortitudinem. Formae vero quae non individuantur per aliquod suppositum, sed per seipsas quia scilicet sunt formae subsistentes), si intelligerentur secundum quod sunt in seipsis, non possent communicari nec re neque ratione; sed forte per similitudinem, sicut dictum est de individuis.
Sed quia formas simplices per se subsistentes non possumus intelligere secundum quod sunt, sed intelligimus eas ad modum rerum compositarum habentium formas in materia; ideo, ut dictum est, imponimus eis nomina concreta significantia naturam in aliquo supposito. Unde, quantum pertinet ad rationem nominum, eadem ratio est de nominibus quae a nobis imponuntur ad significandum naturas rerum compositarum, et de nominibus quae a nobis imponuntur ad significandum naturas simplices subsistentes. Unde, cum hoc nomen Deus impositum sit ad significandum naturam divinam, ut dictum est; natura autem divina multiplicabilis non est, ut supra ostensum est, sequitur quod hoc nomen Deus incommunicabile quidem sit secundum rem, sed communicabile sit secundum opinionem, quemadmodum hoc nomen sol esset communicabile secundum opinionem ponentium multos soles.
Et secundum hoc dicitur Gal. IV, his qui natura non sunt dii, serviebatis; Glossa, non sunt dii natura, sed opinione hominum. Est nihilominus communicabile hoc nomen Deus, non secundum suam totam significationem, sed secundum aliquid eius, per quandam similitudinem, ut dii dicantur, qui participant aliquid divinum per similitudinem, secundum illud, ego dixi, dii estis. Si vero esset aliquod nomen impositum ad significandum Deum non ex parte naturae, sed ex parte suppositi, secundum quod consideratur ut hoc aliquid, illud nomen esset omnibus modis incommunicabile, sicut forte est nomen tetragrammaton apud Hebraeos. Et est simile si quis imponeret nomen soli designans hoc individuum.
6 Reply to Objection 1: The divine nature is only communicable according to the participation of some similitude.
6 Ad primum ergo dicendum quod natura divina non est communicabilis nisi secundum similitudinis participationem.
7 Reply to Objection 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.
7 Ad secundum dicendum quod hoc nomen Deus est nomen appellativum, et non proprium, quia significat naturam divinam ut in habente; licet ipse Deus, secundum rem, non sit nec universalis nec particularis. Nomina enim non sequuntur modum essendi qui est in rebus, sed modum essendi secundum quod in cognitione nostra est. Et tamen, secundum rei veritatem, est incommunicabile, secundum quod dictum est de hoc nomine sol.
8 Reply to Objection 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.
8 Ad tertium dicendum quod haec nomina bonus, sapiens, et similia, imposita quidem sunt a perfectionibus procedentibus a Deo in creaturas, non tamen sunt imposita ad significandum divinam naturam, sed ad significandum ipsas perfectiones absolute. Et ideo etiam secundum rei veritatem sunt communicabilia multis. Sed hoc nomen Deus impositum est ab operatione propria Deo, quam experimur continue, ad significandum divinam naturam.
