1 Objection 1: It seems that the perfections of all things are not in God. For God is simple, as shown above Question 3, Article 7); whereas the perfections of things are many and diverse. Therefore the perfections of all things are not in God.
1 Ad secundum sic proceditur. Videtur quod in Deo non sint perfectiones omnium rerum. Deus enim simplex est, ut ostensum est. Sed perfectiones rerum sunt multae et diversae. Ergo in Deo non sunt omnes perfectiones rerum.
2 Objection 2: Further, opposites cannot coexist. Now the perfections of things are opposed to each other, for each thing is perfected by its specific difference. But the differences by which genera are divided, and species constituted, are opposed to each other. Therefore because opposites cannot coexist in the same subject, it seems that the perfections of all things are not in God.
2 Praeterea, opposita non possunt esse in eodem. Sed perfectiones rerum sunt oppositae, unaquaeque enim species perficitur per suam differentiam specificam; differentiae autem quibus dividitur genus et constituuntur species, sunt oppositae. Cum ergo opposita non possint simul esse in eodem, videtur quod non omnes rerum perfectiones sint in Deo.
3 Objection 3: Further, a living thing is more perfect than what merely exists; and an intelligent thing than what merely lives. Therefore life is more perfect than existence; and knowledge than life. But the essence of God is existence itself. Therefore He has not the perfections of life, and knowledge, and other similar perfections.
3 Praeterea, vivens est perfectius quam ens, et sapiens quam vivens, ergo et vivere est perfectius quam esse, et sapere quam vivere. Sed essentia Dei est ipsum esse. Ergo non habet in se perfectionem vitae et sapientiae, et alias huiusmodi perfectiones.
4 On the contrary, Dionysius says Div. Nom. v) that God in His one existence prepossesses all things.
4 Sed contra est quod dicit Dionysius, cap. V de Div. Nom., quod Deus in uno existentia omnia praehabet.
5 I answer that, All created perfections are in God. Hence He is spoken of as universally perfect, because He lacks not says the Commentator, Metaph. v) any excellence which may be found in any genus. This may be seen from two considerations. First, because whatever perfection exists in an effect must be found in the effective cause: either in the same formality, if it is a univocal agent, as when man reproduces man; or in a more eminent degree, if it is an equivocal agent, thus in the sun is the likeness of whatever is generated by the sun's power.
Now it is plain that the effect pre-exists virtually in the efficient cause: and although to pre-exist in the potentiality of a material cause is to pre-exist in a more imperfect way, since matter as such is imperfect, and an agent as such is perfect; still to pre-exist virtually in the efficient cause is to pre-exist not in a more imperfect, but in a more perfect way. Since therefore God is the first effective cause of things, the perfections of all things must pre-exist in God in a more eminent way.
Dionysius implies the same line of argument by saying of God Div. Nom. v): It is not that He is this and not that, but that He is all, as the cause of all. Secondly, from what has been already proved, God is existence itself, of itself subsistent Question 3, Article 4). Consequently, He must contain within Himself the whole perfection of being. For it is clear that if some hot thing has not the whole perfection of heat, this is because heat is not participated in its full perfection; but if this heat were self-subsisting, nothing of the virtue of heat would be wanting to it.
Since therefore God is subsisting being itself, nothing of the perfection of being can be wanting to Him. Now all created perfections are included in the perfection of being; for things are perfect, precisely so far as they have being after some fashion. It follows therefore that the perfection of no one thing is wanting to God. This line of argument, too, is implied by Dionysius Div. Nom. v), when he says that, God exists not in any single mode, but embraces all being within Himself, absolutely, without limitation, uniformly; and afterwards he adds that, He is the very existence to subsisting things.
5 Respondeo dicendum quod in Deo sunt perfectiones omnium rerum. Unde et dicitur universaliter perfectus, quia non deest ei aliqua nobilitas quae inveniatur in aliquo genere, ut dicit Commentator in V Metaphys. Et hoc quidem ex duobus considerari potest. Primo quidem, per hoc quod quidquid perfectionis est in effectu, oportet inveniri in causa effectiva, vel secundum eandem rationem, si sit agens univocum, ut homo generat hominem; vel eminentiori modo, si sit, agens aequivocum, sicut in sole est similitudo eorum quae generantur per virtutem solis.
Manifestum est enim quod effectus praeexistit virtute in causa agente, praeexistere autem in virtute causae agentis, non est praeexistere imperfectiori modo, sed perfectiori; licet praeexistere in potentia causae materialis, sit praeexistere imperfectiori modo, eo quod materia, inquantum huiusmodi, est imperfecta; agens vero, inquantum huiusmodi, est perfectum. Cum ergo Deus sit prima causa effectiva rerum, oportet omnium rerum perfectiones praeexistere in Deo secundum eminentiorem modum. Et hanc rationem tangit Dionysius, cap. V de Div. Nom., dicens de Deo quod non hoc quidem est, hoc autem non est, sed omnia est, ut omnium causa.
Secundo vero, ex hoc quod supra ostensum est, quod Deus est ipsum esse per se subsistens, ex quo oportet quod totam perfectionem essendi in se contineat. Manifestum est enim quod, si aliquod calidum non habeat totam perfectionem calidi, hoc ideo est, quia calor non participatur secundum perfectam rationem, sed si calor esset per se subsistens, non posset ei aliquid deesse de virtute caloris. Unde, cum Deus sit ipsum esse subsistens, nihil de perfectione essendi potest ei deesse. Omnium autem perfectiones pertinent ad perfectionem essendi, secundum hoc enim aliqua perfecta sunt, quod aliquo modo esse habent.
Unde sequitur quod nullius rei perfectio Deo desit. Et hanc etiam rationem tangit Dionysius, cap. V de Div. Nom., dicens quod Deus non quodammodo est existens, sed simpliciter et incircumscripte totum in seipso uniformiter esse praeaccipit, et postea subdit quod ipse est esse subsistentibus.
6 Reply to Objection 1: Even as the sun as Dionysius remarks, Div. Nom. v)), while remaining one and shining uniformly, contains within itself first and uniformly the substances of sensible things, and many and diverse qualities; a fortiori should all things in a kind of natural unity pre-exist in the cause of all things; and thus things diverse and in themselves opposed to each other, pre-exist in God as one, without injury to His simplicity. This suffices for the Reply to the Second Objection.
6 Ad primum ergo dicendum quod, sicut sol, ut dicit Dionysius, cap. V de Div. Nom., sensibilium substantias et qualitates multas et differentes, ipse unus existens et uniformiter lucendo, in seipso uniformiter praeaccipit; ita multo magis in causa omnium necesse est praeexistere omnia secundum naturalem unionem. Et sic, quae sunt diversa et opposita in seipsis, in Deo praeexistunt ut unum, absque detrimento simplicitatis ipsius. Et per hoc patet solutio ad secundum.
7 Reply to Objection 3: The same Dionysius says Div. Nom. v) that, although existence is more perfect than life, and life than wisdom, if they are considered as distinguished in idea; nevertheless, a living thing is more perfect than what merely exists, because living things also exist and intelligent things both exist and live. Although therefore existence does not include life and wisdom, because that which participates in existence need not participate in every mode of existence; nevertheless God's existence includes in itself life and wisdom, because nothing of the perfection of being can be wanting to Him who is subsisting being itself.
7 Ad tertium dicendum quod, sicut in eodem capite idem Dionysius dicit, licet ipsum esse sit perfectius quam vita, et ipsa vita quam ipsa sapientia, si considerentur secundum quod distinguuntur ratione, tamen vivens est perfectius quam ens tantum, quia vivens etiam est ens; et sapiens est ens et vivens. Licet igitur ens non includat in se vivens et sapiens, quia non oportet quod illud quod participat esse, participet ipsum secundum omnem modum essendi, tamen ipsum esse Dei includit in se vitam et sapientiam; quia nulla de perfectionibus essendi potest deesse ei quod est ipsum esse subsistens.
