1 Objection 1: It would seem that in creatures there is not necessarily found a trace of the Trinity. For anything can be traced through its traces. But the trinity of persons cannot be traced from the creatures, as was above stated Question 32, Article 1). Therefore there is no trace of the Trinity in creatures.
1 Ad septimum sic proceditur. Videtur quod in creaturis non sit necesse inveniri vestigium Trinitatis. Per sua enim vestigia unumquodque investigari potest. Sed Trinitas personarum non potest investigari ex creaturis, ut supra habitum est. Ergo vestigia Trinitatis non sunt in creatura.
2 Objection 2: Further, whatever is in creatures is created. Therefore if the trace of the Trinity is found in creatures according to some of their properties, and if everything created has a trace of the Trinity, it follows that we can find a trace of the Trinity in each of these properties): and so on to infinitude.
2 Praeterea, quidquid in creatura est, creatum est. Si igitur vestigium Trinitatis invenitur in creatura secundum aliquas proprietates suas, et omne creatum habet vestigium Trinitatis, oportet in unaquaque illarum inveniri etiam vestigium Trinitatis, et sic in infinitum.
3 Objection 3: Further, the effect represents only its own cause. But the causality of creatures belongs to the common nature, and not to the relations whereby the Persons are distinguished and numbered. Therefore in the creature is to be found a trace not of the Trinity but of the unity of essence.
3 Praeterea, effectus non repraesentat nisi suam causam. Sed causalitas creaturarum pertinet ad naturam communem, non autem ad relationes, quibus personae distinguuntur et numerantur. Ergo in creatura non invenitur vestigium Trinitatis, sed solum unitatis essentiae.
4 On the contrary, Augustine says De Trin. vi, 10), that the trace of the Trinity appears in creatures.
4 Sed contra est quod Augustinus dicit, VI de Trin., quod Trinitatis vestigium in creatura apparet.
5 I answer that, Every effect in some degree represents its cause, but diversely. For some effects represent only the causality of the cause, but not its form; as smoke represents fire. Such a representation is called a trace: for a trace shows that someone has passed by but not who it is. Other effects represent the cause as regards the similitude of its form, as fire generated represents fire generating; and a statue of Mercury represents Mercury; and this is called the representation of image.
Now the processions of the divine Persons are referred to the acts of intellect and will, as was said above Question 27). For the Son proceeds as the word of the intellect; and the Holy Ghost proceeds as love of the will. Therefore in rational creatures, possessing intellect and will, there is found the representation of the Trinity by way of image, inasmuch as there is found in them the word conceived, and the love proceeding. But in all creatures there is found the trace of the Trinity, inasmuch as in every creature are found some things which are necessarily reduced to the divine Persons as to their cause.
For every creature subsists in its own being, and has a form, whereby it is determined to a species, and has relation to something else. Therefore as it is a created substance, it represents the cause and principle; and so in that manner it shows the Person of the Father, Who is the principle from no principle. According as it has a form and species, it represents the Word as the form of the thing made by art is from the conception of the craftsman.
According as it has relation of order, it represents the Holy Ghost, inasmuch as He is love, because the order of the effect to something else is from the will of the Creator. And therefore Augustine says De Trin. vi 10) that the trace of the Trinity is found in every creature, according as it is one individual, and according as it is formed by a species, and according as it has a certain relation of order. And to these also are reduced those three, number, weight, and measure, mentioned in the Book of Wisdom 9, 21).
For measure refers to the substance of the thing limited by its principles, number refers to the species, weight refers to the order. And to these three are reduced the other three mentioned by Augustine De Nat. Boni iii), mode, species, and order, and also those he mentions Questions. 83, qu. 18): that which exists; whereby it is distinguished; whereby it agrees. For a thing exists by its substance, is distinct by its form, and agrees by its order. Other similar expressions may be easily reduced to the above.
5 Respondeo dicendum quod omnis effectus aliqualiter repraesentat suam causam, sed diversimode. Nam aliquis effectus repraesentat solam causalitatem causae, non autem formam eius, sicut fumus repraesentat ignem, et talis repraesentatio dicitur esse repraesentatio vestigii; vestigium enim demonstrat motum alicuius transeuntis, sed non qualis sit. Aliquis autem effectus repraesentat causam quantum ad similitudinem formae eius, sicut ignis generatus ignem generantem, et statua Mercurii Mercurium, et haec est repraesentatio imaginis. Processiones autem divinarum personarum attenduntur secundum actus intellectus et voluntatis, sicut supra dictum est, nam filius procedit ut verbum intellectus, spiritus sanctus ut amor voluntatis.
In creaturis igitur rationalibus, in quibus est intellectus et voluntas, invenitur repraesentatio Trinitatis per modum imaginis, inquantum invenitur in eis verbum conceptum et amor procedens. Sed in creaturis omnibus invenitur repraesentatio Trinitatis per modum vestigii, inquantum in qualibet creatura inveniuntur aliqua quae necesse est reducere in divinas personas sicut in causam. Quaelibet enim creatura subsistit in suo esse, et habet formam per quam determinatur ad speciem, et habet ordinem ad aliquid aliud. Secundum igitur quod est quaedam substantia creata, repraesentat causam et principium, et sic demonstrat personam patris, qui est principium non de principio.
Secundum autem quod habet quandam formam et speciem, repraesentat verbum; secundum quod forma artificiati est ex conceptione artificis. Secundum autem quod habet ordinem, repraesentat spiritum sanctum, inquantum est amor, quia ordo effectus ad aliquid alterum est ex voluntate creantis. Et ideo dicit Augustinus, in VI Lib. de Trin., quod vestigium Trinitatis invenitur in unaquaque creatura, secundum quod unum aliquid est, et secundum quod aliqua specie formatur, et secundum quod quendam ordinem tenet. Et ad haec etiam reducuntur illa tria, numerus, pondus et mensura, quae ponuntur Sap.
XI, nam mensura refertur ad substantiam rei limitatam suis principiis, numerus ad speciem, pondus ad ordinem. Et ad haec etiam reducuntur alia tria quae ponit Augustinus, modus species et ordo. Et ea quae ponit in libro octoginta trium quaest. quod constat, quod discernitur, quod congruit, constat enim aliquid per suam substantiam, discernitur per formam, congruit per ordinem. Et in idem de facili reduci possunt quaecumque sic dicuntur.
6 Reply to Objection 1: The representation of the trace is to be referred to the appropriations: in which manner we are able to arrive at a knowledge of the trinity of the divine persons from creatures, as we have said Question 32, Article 1).
6 Ad primum ergo dicendum quod repraesentatio vestigii attenditur secundum appropriata, per quem modum ex creaturis in Trinitatem divinarum personarum veniri potest, ut dictum est.
7 Reply to Objection 2: A creature properly speaking is a thing self-subsisting; and in such are the three above-mentioned things to be found. Nor is it necessary that these three things should be found in all that exists in the creature; but only to a subsisting being is the trace ascribed in regard to those three things.
7 Ad secundum dicendum quod creatura est res proprie subsistens, in qua est praedicta tria invenire. Neque oportet quod in quolibet eorum quae ei insunt, haec tria inveniantur, sed secundum ea vestigium rei subsistenti attribuitur.
8 Reply to Objection 3: The processions of the persons are also in some way the cause and type of creation; as appears from the above Article 6).
8 Ad tertium dicendum quod etiam processiones personarum sunt causa et ratio creationis aliquo modo, ut dictum est.
