1 Objection 1: It would seem that the notional acts are not to be attributed to the persons. For Boethius says De Trin.): Whatever is predicated of God, of whatever genus it be, becomes the divine substance, except what pertains to the relation. But action is one of the ten genera. Therefore any action attributed to God belongs to His essence, and not to a notion.
1 Ad primum sic proceditur. Videtur quod actus notionales non sint personis attribuendi. Dicit enim Boetius, in libro de Trin., quod omnia genera, cum quis in divinam vertit praedicationem, in divinam mutantur substantiam, exceptis relativis. Sed actio est unum de decem generibus. Si igitur actio aliqua Deo attribuitur, ad eius essentiam pertinebit, et non ad notionem.
2 Objection 2: Further, Augustine says De Trin. v, 4, 5) that, everything which is said of God, is said of Him as regards either His substance, or relation. But whatever belongs to the substance is signified by the essential attributes; and whatever belongs to the relations, by the names of the persons, or by the names of the properties. Therefore, in addition to these, notional acts are not to be attributed to the persons.
2 Praeterea, Augustinus dicit, V de Trin., omne quod de Deo dicitur, aut dicitur secundum substantiam, aut secundum relationem. Sed ea quae ad substantiam pertinent, significantur per essentialia attributa, quae vero ad relationem, per nomina personarum et per nomina proprietatum. Non sunt ergo, praeter haec, attribuendi personis notionales actus.
3 Objection 3: Further, the nature of action is of itself to cause passion. But we do not place passions in God. Therefore neither are notional acts to be placed in God.
3 Praeterea, proprium actionis est ex se passionem inferre. Sed in divinis non ponimus passiones. Ergo neque actus notionales ibi ponendi sunt.
4 On the contrary, Augustine Fulgentius, De Fide ad Petrum ii) says: It is a property of the Father to beget the Son. Therefore notional acts are to be placed in God.
4 Sed contra est quod Augustinus dicit, in libro de fide ad Petrum, proprium patris est, quod filium genuit. Sed generatio actus quidam est. Ergo actus notionales ponendi sunt in divinis.
5 I answer that, In the divine persons distinction is founded on origin. But origin can be properly designated only by certain acts. Wherefore, to signify the order of origin in the divine persons, we must attribute notional acts to the persons.
5 Respondeo dicendum quod in divinis personis attenditur distinctio secundum originem. Origo autem convenienter designari non potest nisi per aliquos actus. Ad designandum igitur ordinem originis in divinis personis, necessarium fuit attribuere personis actus notionales.
6 Reply to Objection 1: Every origin is designated by an act. In God there is a twofold order of origin: one, inasmuch as the creature proceeds from Him, and this is common to the three persons; and so those actions which are attributed to God to designate the proceeding of creatures from Him, belong to His essence. Another order of origin in God regards the procession of person from person; wherefore the acts which designate the order of this origin are called notional; because the notions of the persons are the mutual relations of the persons, as is clear from what was above explained Question 32, Article 2).
6 Ad primum ergo dicendum quod omnis origo designatur per aliquem actum. Duplex autem ordo originis attribui Deo potest. Unus quidem, secundum quod creatura ab eo progreditur, et hoc commune est tribus personis. Et ideo actiones quae attribuuntur Deo ad designandum processum creaturarum ab ipso, ad essentiam pertinent. Alius autem ordo originis in divinis attenditur secundum processionem personae a persona. Unde actus designantes huius originis ordinem, notionales dicuntur, quia notiones personarum sunt personarum habitudines ad invicem, ut ex dictis patet.
7 Reply to Objection 2: The notional acts differ from the relations of the persons only in their mode of signification; and in reality are altogether the same. Whence the Master says that generation and nativity in other words are paternity and filiation Sent. i, D, xxvi). To see this, we must consider that the origin of one thing from another is firstly inferred from movement: for that anything be changed from its disposition by movement evidently arises from some cause.
Hence action, in its primary sense, means origin of movement; for, as movement derived from another into a mobile object, is called passion, so the origin of movement itself as beginning from another and terminating in what is moved, is called action. Hence, if we take away movement, action implies nothing more than order of origin, in so far as action proceeds from some cause or principle to what is from that principle. Consequently, since in God no movement exists, the personal action of the one producing a person is only the habitude of the principle to the person who is from the principle; which habitudes are the relations, or the notions.
Nevertheless we cannot speak of divine and intelligible things except after the manner of sensible things, whence we derive our knowledge, and wherein actions and passions, so far as these imply movement, differ from the relations which result from action and passion, and therefore it was necessary to signify the habitudes of the persons separately after the manner of act, and separately after the manner of relations. Thus it is evident that they are really the same, differing only in their mode of signification.
7 Ad secundum dicendum quod actus notionales secundum modum significandi tantum differunt a relationibus personarum; sed re sunt omnino idem. Unde Magister dicit, in I Sent., XXVI dist., quod generatio et nativitas aliis nominibus dicuntur paternitas et filiatio. Ad cuius evidentiam, attendendum est quod primo coniicere potuimus originem alicuius ab alio, ex motu, quod enim aliqua res a sua dispositione removeretur per motum, manifestum fuit hoc ab aliqua causa accidere. Et ideo actio, secundum primam nominis impositionem, importat originem motus, sicut enim motus, prout est in mobili ab aliquo, dicitur passio; ita origo ipsius motus, secundum quod incipit ab alio et terminatur in id quod movetur, vocatur actio. Remoto igitur motu, actio nihil aliud importat quam ordinem originis, secundum quod a causa aliqua vel principio procedit in id quod est a principio. Unde, cum in divinis non sit motus, actio personalis producentis personam, nihil aliud est quam habitudo principii ad personam quae est a principio. Quae quidem habitudines sunt ipsae relationes vel notiones. Quia tamen de divinis et intelligibilibus rebus loqui non possumus nisi secundum modum rerum sensibilium, a quibus cognitionem accipimus; et in quibus actiones et passiones, inquantum motum implicant, aliud sunt a relationibus quae ex actionibus et passionibus consequuntur, oportuit seorsum significari habitudines personarum per modum actus, et seorsum per modum relationum. Et sic patet quod sunt idem secundum rem, sed differunt solum secundum modum significandi.
8 Reply to Objection 3: Action, so far as it means origin of movement, naturally involves passion; but action in that sense is not attributed to God. Whence, passions are attributed to Him only from a grammatical standpoint, and in accordance with our manner of speaking, as we attribute to beget with the Father, and to the Son to be begotten.
8 Ad tertium dicendum quod actio, secundum quod importat originem motus, infert ex se passionem, sic autem non ponitur actio in divinis personis. Unde non ponuntur ibi passiones, nisi solum grammatice loquendo, quantum ad modum significandi; sicut patri attribuimus generare, et filio generari.
