1 Objection 1: It would seem that the exclusive word alone solus) is not to be added to an essential term in God. For, according to the Philosopher Elench. ii, 3), He is alone who is not with another. But God is with the angels and the souls of the saints. Therefore we cannot say that God is alone.
1 Ad tertium sic proceditur. Videtur quod dictio exclusiva solus non sit addenda termino essentiali in divinis. Quia secundum philosophum, in II Elench., solus est qui cum alio non est. Sed Deus est cum Angelis et sanctis animabus. Ergo non possumus dicere Deum solum.
2 Objection 2: Further, whatever is joined to the essential term in God can be predicated of every person per se, and of all the persons together; for, as we can properly say that God is wise, we can say the Father is a wise God; and the Trinity is a wise God. But Augustine says De Trin. vi, 9): We must consider the opinion that the Father is not true God alone. Therefore God cannot be said to be alone.
2 Praeterea, quidquid adiungitur termino essentiali in divinis, potest praedicari de qualibet persona per se, et de omnibus simul, quia enim convenienter dicitur sapiens Deus, possumus dicere, pater est sapiens Deus, et Trinitas est sapiens Deus. Sed Augustinus, in VI de Trin., dicit, consideranda est illa sententia, qua dicitur non esse patrem verum Deum solum. Ergo non potest dici solus Deus.
3 Objection 3: Further if this expression alone is joined to an essential term, it would be so joined as regards either the personal predicate or the essential predicate. But it cannot be the former, as it is false to say, God alone is Father, since man also is a father; nor, again, can it be applied as regards the latter, for, if this saying were true, God alone creates, it would follow that the Father alone creates, as whatever is said of God can be said of the Father; and it would be false, as the Son also creates. Therefore this expression alone cannot be joined to an essential term in God.
3 Praeterea, si haec dictio solus adiungitur termino essentiali, aut hoc erit respectu praedicati personalis, aut respectu praedicati essentialis. Sed non respectu praedicati personalis, quia haec est falsa, solus Deus est pater, cum etiam homo sit pater. Neque etiam respectu praedicati essentialis. Quia si haec esset vera, solus Deus creat, videtur sequi quod haec esset vera, solus pater creat, quia quidquid dicitur de Deo, potest dici de patre. Haec autem est falsa, quia etiam filius est creator. Non ergo haec dictio solus potest in divinis adiungi termino essentiali.
4 On the contrary, It is said, To the King of ages, immortal, invisible, the only God 1 Tim. 1, 17).
4 Sed contra est quod dicitur I ad Tim. I, regi saeculorum immortali, invisibili, soli Deo.
5 I answer that, This term alone can be taken as a categorematical term, or as a syncategorematical term. A categorematical term is one which ascribes absolutely its meaning to a given suppositum; as, for instance, white to man, as when we say a white man. If the term alone is taken in this sense, it cannot in any way be joined to any term in God; for it would mean solitude in the term to which it is joined; and it would follow that God was solitary, against what is above stated Article 2). A syncategorematical term imports the order of the predicate to the subject; as this expression every one or no one; and likewise the term alone, as excluding every other suppositum from the predicate. Thus, when we say, Socrates alone writes, we do not mean that Socrates is solitary, but that he has no companion in writing, though many others may be with him. In this way nothing prevents the term alone being joined to any essential term in God, as excluding the predicate from all things but God; as if we said God alone is eternal, because nothing but God is eternal.
5 Respondeo dicendum quod haec dictio solus potest accipi ut categorematica vel syncategorematica. Dicitur autem dictio categorematica, quae absolute ponit rem significatam circa aliquod suppositum; ut albus circa hominem, cum dicitur homo albus. Si ergo sic accipiatur haec dictio solus, nullo modo potest adiungi alicui termino in divinis, quia poneret solitudinem circa terminum cui adiungeretur, et sic sequeretur Deum esse solitarium; quod est contra praedicta. Dictio vero syncategorematica dicitur, quae importat ordinem praedicati ad subiectum, sicut haec dictio omnis, vel nullus. Et similiter haec dictio solus, quia excludit omne aliud suppositum a consortio praedicati. Sicut, cum dicitur, solus Socrates scribit, non datur intelligi quod Socrates sit solitarius; sed quod nullus sit ei consors in scribendo, quamvis cum eo multis existentibus. Et per hunc modum nihil prohibet hanc dictionem solus adiungere alicui essentiali termino in divinis, inquantum excluduntur omnia alia a Deo a consortio praedicati, ut si dicamus, solus Deus est aeternus, quia nihil praeter Deum est aeternum.
6 Reply to Objection 1: Although the angels and the souls of the saints are always with God, nevertheless, if plurality of persons did not exist in God, He would be alone or solitary. For solitude is not removed by association with anything that is extraneous in nature; thus anyone is said to be alone in a garden, though many plants and animals are with him in the garden. Likewise, God would be alone or solitary, though angels and men were with Him, supposing that several persons were not within Him. Therefore the society of angels and of souls does not take away absolute solitude from God; much less does it remove respective solitude, in reference to a predicate.
6 Ad primum ergo dicendum quod, licet Angeli et animae sanctae semper sint cum Deo, tamen, si non esset pluralitas personarum in divinis, sequeretur, quod Deus esset solus vel solitarius. Non enim tollitur solitudo per associationem alicuius quod est extraneae naturae, dicitur enim aliquis solus esse in horto, quamvis sint ibi multae plantae et animalia. Et similiter diceretur Deus esse solus vel solitarius, Angelis et hominibus cum eo existentibus, si non essent in divinis personae plures. Consociatio igitur Angelorum et animarum non excludit solitudinem absolutam a divinis, et multo minus solitudinem respectivam, per comparationem ad aliquod praedicatum.
7 Reply to Objection 2: This expression alone, properly speaking, does not affect the predicate, which is taken formally, for it refers to the suppositum, as excluding any other suppositum from the one which it qualifies. But the adverb only, being exclusive, can be applied either to subject or predicate. For we can say, Only Socrates, that is, no one else, runs: and Socrates runs only, that is, he does nothing else. Hence it is not properly said that the Father is God alone, or the Trinity is God alone, unless some implied meaning be assumed in the predicate, as, for instance, The Trinity is God Who alone is God. In that sense it can be true to say that the Father is that God Who alone is God, if the relative be referred to the predicate, and not to the suppositum. So, when Augustine says that the Father is not God alone, but that the Trinity is God alone, he speaks expositively, as he might explain the words, To the King of ages, invisible, the only God, as applying not to the Father, but to the Trinity alone.
7 Ad secundum dicendum quod haec dictio solus, proprie loquendo, non ponitur ex parte praedicati, quod sumitur formaliter, respicit enim suppositum, inquantum excludit aliud suppositum ab eo cui adiungitur. Sed hoc adverbium tantum, cum sit exclusivum, potest poni ex parte subiecti, et ex parte praedicati, possumus enim dicere, tantum Socrates currit, idest nullus alius; et, Socrates currit tantum, idest nihil aliud facit. Unde non proprie dici potest, pater est solus Deus, vel, Trinitas est solus Deus, nisi forte ex parte praedicati intelligatur aliqua implicatio, ut dicatur, Trinitas est Deus qui est solus Deus. Et secundum hoc etiam posset esse vera ista, pater est Deus qui est solus Deus, si relativum referret praedicatum, et non suppositum. Augustinus autem, cum dicit patrem non esse solum Deum, sed Trinitatem esse solum Deum, loquitur expositive, ac si diceret, cum dicitur, regi saeculorum, invisibili, soli Deo, non est exponendum de persona patris, sed de sola Trinitate.
8 Reply to Objection 3: In both ways can the term alone be joined to an essential term. For this proposition, God alone is Father, can mean two things, because the word Father can signify the person of the Father; and then it is true; for no man is that person: or it can signify that relation only; and thus it is false, because the relation of paternity is found also in others, though not in a univocal sense. Likewise it is true to say God alone creates; nor, does it follow, therefore the Father alone creates, because, as logicians say, an exclusive diction so fixes the term to which it is joined that what is said exclusively of that term cannot be said exclusively of an individual contained in that term: for instance, from the premiss, Man alone is a mortal rational animal, we cannot conclude, therefore Socrates alone is such.
8 Ad tertium dicendum quod utroque modo potest haec dictio solus adiungi termino essentiali. Haec enim propositio, solus Deus est pater, est duplex. Quia ly pater potest praedicare personam patris, et sic est vera, non enim homo est illa persona. Vel potest praedicare relationem tantum, et sic est falsa, quia relatio paternitatis etiam in aliis invenitur, licet non univoce. Similiter haec est vera, solus Deus creat. Nec tamen sequitur, ergo solus pater, quia, ut sophistae dicunt, dictio exclusiva immobilitat terminum cui adiungitur, ut non possit fieri sub eo descensus pro aliquo suppositorum; non enim sequitur, solus homo est animal rationale mortale, ergo solus Socrates.
