1 Objection 1: It seems that this name HE WHO IS is not the most proper name of God. For this name God is an incommunicable name. But this name HE WHO IS, is not an incommunicable name. Therefore this name HE WHO IS is not the most proper name of God.
1 Ad undecimum sic proceditur. Videtur quod hoc nomen qui est non sit maxime proprium nomen Dei. Hoc enim nomen Deus est nomen incommunicabile, ut dictum est. Sed hoc nomen qui est non est nomen incommunicabile. Ergo hoc nomen qui est non est maxime proprium nomen Dei.
2 Objection 2: Further, Dionysius says Div. Nom. iii) that the name of good excellently manifests all the processions of God. But it especially belongs to God to be the universal principle of all things. Therefore this name good is supremely proper to God, and not this name HE WHO IS.
2 Praeterea, Dionysius dicit, III cap. de Div. Nom., quod boni nominatio est manifestativa omnium Dei processionum. Sed hoc maxime Deo convenit, quod sit universale rerum principium. Ergo hoc nomen bonum est maxime proprium Dei, et non hoc nomen qui est.
3 Objection 3: Further, every divine name seems to imply relation to creatures, for God is known to us only through creatures. But this name HE WHO IS imports no relation to creatures. Therefore this name HE WHO IS is not the most applicable to God.
3 Praeterea, omne nomen divinum videtur importare relationem ad creaturas, cum Deus non cognoscatur a nobis nisi per creaturas. Sed hoc nomen qui est nullam importat habitudinem ad creaturas. Ergo hoc nomen qui est non est maxime proprium nomen Dei.
4 On the contrary, It is written that when Moses asked, If they should say to me, What is His name? what shall I say to them? The Lord answered him, Thus shalt thou say to them, HE WHO IS hath sent me to you Ex. 3, 13, 14). Therefor this name HE WHO IS most properly belongs to God.
4 Sed contra est quod dicitur Exod. III, quod Moysi quaerenti, si dixerint mihi, quod est nomen eius? Quid dicam eis? Et respondit ei dominus, sic dices eis, qui est misit me ad vos. Ergo hoc nomen qui est est maxime proprium nomen Dei.
5 I answer that, This name HE WHO IS is most properly applied to God, for three reasons: First, because of its signification. For it does not signify form, but simply existence itself. Hence since the existence of God is His essence itself, which can be said of no other Question 3, Article 4), it is clear that among other names this one specially denominates God, for everything is denominated by its form. Secondly, on account of its universality. For all other names are either less universal, or, if convertible with it, add something above it at least in idea; hence in a certain way they inform and determine it.
Now our intellect cannot know the essence of God itself in this life, as it is in itself, but whatever mode it applies in determining what it understands about God, it falls short of the mode of what God is in Himself. Therefore the less determinate the names are, and the more universal and absolute they are, the more properly they are applied to God. Hence Damascene says De Fide Orth. i) that, HE WHO IS, is the principal of all names applied to God; for comprehending all in itself, it contains existence itself as an infinite and indeterminate sea of substance.
Now by any other name some mode of substance is determined, whereas this name HE WHO IS, determines no mode of being, but is indeterminate to all; and therefore it denominates the infinite ocean of substance. Thirdly, from its consignification, for it signifies present existence; and this above all properly applies to God, whose existence knows not past or future, as Augustine says De Trin. v).
5 Respondeo dicendum quod hoc nomen qui est triplici ratione est maxime proprium nomen Dei. Primo quidem, propter sui significationem. Non enim significat formam aliquam, sed ipsum esse. Unde, cum esse Dei sit ipsa eius essentia, et hoc nulli alii conveniat, ut supra ostensum est, manifestum est quod inter alia nomina hoc maxime proprie nominat Deum, unumquodque enim denominatur a sua forma. Secundo, propter eius universalitatem. Omnia enim alia nomina vel sunt minus communia; vel, si convertantur cum ipso, tamen addunt aliqua supra ipsum secundum rationem; unde quodammodo informant et determinant ipsum. Intellectus autem noster non potest ipsam Dei essentiam cognoscere in statu viae, secundum quod in se est, sed quemcumque modum determinet circa id quod de Deo intelligit, deficit a modo quo Deus in se est. Et ideo, quanto aliqua nomina sunt minus determinata, et magis communia et absoluta, tanto magis proprie dicuntur de Deo a nobis. Unde et Damascenus dicit quod principalius omnibus quae de Deo dicuntur nominibus, est qui est, totum enim in seipso comprehendens, habet ipsum esse velut quoddam pelagus substantiae infinitum et indeterminatum. Quolibet enim alio nomine determinatur aliquis modus substantiae rei, sed hoc nomen qui est nullum modum essendi determinat, sed se habet indeterminate ad omnes; et ideo nominat ipsum pelagus substantiae infinitum. Tertio vero, ex eius consignificatione. Significat enim esse in praesenti, et hoc maxime proprie de Deo dicitur, cuius esse non novit praeteritum vel futurum, ut dicit Augustinus in V de Trin.
6 Reply to Objection 1: This name HE WHO IS is the name of God more properly than this name God, as regards its source, namely, existence; and as regards the mode of signification and consignification, as said above. But as regards the object intended by the name, this name God is more proper, as it is imposed to signify the divine nature; and still more proper is the Tetragrammaton, imposed to signify the substance of God itself, incommunicable and, if one may so speak, singular.
6 Ad primum ergo dicendum quod hoc nomen qui est est magis proprium nomen Dei quam hoc nomen Deus, quantum ad id a quo imponitur, scilicet ab esse, et quantum ad modum significandi et consignificandi, ut dictum est. Sed quantum ad id ad quod imponitur nomen ad significandum, est magis proprium hoc nomen Deus, quod imponitur ad significandum naturam divinam. Et adhuc magis proprium nomen est tetragrammaton, quod est impositum ad significandam ipsam Dei substantiam incommunicabilem, et, ut sic liceat loqui, singularem.
7 Reply to Objection 2: 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.
7 Ad secundum dicendum quod hoc nomen bonum est principale nomen Dei inquantum est causa, non tamen simpliciter, nam esse absolute praeintelligitur causae.
8 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. Among these the first is existence, from which comes this name, HE WHO IS.
8 Ad tertium dicendum quod non est necessarium quod omnia nomina divina importent habitudinem ad creaturas; sed sufficit quod imponantur ab aliquibus perfectionibus procedentibus a Deo in creaturas. Inter quas prima est ipsum esse, a qua sumitur hoc nomen qui est.
