1 Objection 1: It seems that God is not truth. For truth consists in the intellect composing and dividing. But in God there is not composition and division. Therefore in Him there is not truth.
1 Ad quintum sic proceditur. Videtur quod Deus non sit veritas. Veritas enim consistit in compositione et divisione intellectus. Sed in Deo non est compositio et divisio. Ergo non est ibi veritas.
2 Objection 2: Further, truth, according to Augustine De Vera Relig. xxxvi) is a likeness to the principle. But in God there is no likeness to a principle. Therefore in God there is not truth.
2 Praeterea, veritas, secundum Augustinum, in libro de vera Relig., est similitudo principii. Sed Dei non est similitudo ad principium. Ergo in Deo non est veritas.
3 Objection 3: Further, whatever is said of God, is said of Him as of the first cause of all things; thus the being of God is the cause of all being; and His goodness the cause of all good. If therefore there is truth in God, all truth will be from Him. But it is true that someone sins. Therefore this will be from God; which is evidently false.
3 Praeterea, quidquid dicitur de Deo, dicitur de eo ut de prima causa omnium, sicut esse Dei est causa omnis esse, et bonitas eius est causa omnis boni. Si ergo in Deo sit veritas, ergo omne verum erit ab ipso. Sed aliquem peccare est verum. Ergo hoc erit a Deo. Quod patet esse falsum.
4 On the contrary, Our Lord says, I am the Way, the Truth, and the Life Jn. 14, 6).
4 Sed contra est quod dicit dominus, Ioan. XIV, ego sum via, veritas et vita.
5 I answer that, As said above Article 1), truth is found in the intellect according as it apprehends a thing as it is; and in things according as they have being conformable to an intellect. This is to the greatest degree found in God. For His being is not only conformed to His intellect, but it is the very act of His intellect; and His act of understanding is the measure and cause of every other being and of every other intellect, and He Himself is His own existence and act of understanding. Whence it follows not only that truth is in Him, but that He is truth itself, and the sovereign and first truth.
5 Respondeo dicendum quod, sicut dictum est, veritas invenitur in intellectu secundum quod apprehendit rem ut est, et in re secundum quod habet esse conformabile intellectui. Hoc autem maxime invenitur in Deo. Nam esse suum non solum est conforme suo intellectui, sed etiam est ipsum suum intelligere; et suum intelligere est mensura et causa omnis alterius esse, et omnis alterius intellectus; et ipse est suum esse et intelligere. Unde sequitur quod non solum in ipso sit veritas, sed quod ipse sit ipsa summa et prima veritas.
6 Reply to Objection 1: Although in the divine intellect there is neither composition nor division, yet in His simple act of intelligence He judges of all things and knows all things complex; and thus there is truth in His intellect.
6 Ad primum ergo dicendum quod, licet in intellectu divino non sit compositio et divisio, tamen secundum suam simplicem intelligentiam iudicat de omnibus, et cognoscit omnia complexa. Et sic in intellectu eius est veritas.
7 Reply to Objection 2: The truth of our intellect is according to its conformity with its principle, that is to say, to the things from which it receives knowledge. The truth also of things is according to their conformity with their principle, namely, the divine intellect. Now this cannot be said, properly speaking, of divine truth; unless perhaps in so far as truth is appropriated to the Son, Who has a principle. But if we speak of divine truth in its essence, we cannot understand this unless the affirmative must be resolved into the negative, as when one says: the Father is of Himself, because He is not from another. Similarly, the divine truth can be called a likeness to the principle, inasmuch as His existence is not dissimilar to His intellect.
7 Ad secundum dicendum quod verum intellectus nostri est secundum quod conformatur suo principio, scilicet rebus, a quibus cognitionem accipit. Veritas etiam rerum est secundum quod conformantur suo principio, scilicet intellectui divino. Sed hoc, proprie loquendo, non potest dici in veritate divina, nisi forte secundum quod veritas appropriatur filio, qui habet principium. Sed si de veritate essentialiter dicta loquamur, non potest intelligi, nisi resolvatur affirmativa in negativam, sicut cum dicitur, pater est a se, quia non est ab alio. Et similiter dici potest similitudo principii veritas divina, inquantum esse suum non est suo intellectui dissimile.
8 Reply to Objection 3: Not-being and privation have no truth of themselves, but only in the apprehension of the intellect. Now all apprehension of the intellect is from God. Hence all the truth that exists in the statement, that a person commits fornication is true, is entirely from God. But to argue, Therefore that this person fornicates is from God, is a fallacy of Accident.
8 Ad tertium dicendum quod non ens et privationes non habent ex seipsis veritatem, sed solum ex apprehensione intellectus. Omnis autem apprehensio intellectus a Deo est, unde quidquid est veritatis in hoc quod dico, istum fornicari est verum, totum est a Deo. Sed si arguatur, ergo istum fornicari est a Deo, est fallacia accidentis.
