Summa Th. I EN Qu.36 a.2
Objection: 1. It would seem that the Holy Ghost does not proceed from the Son. For as Dionysius says (Div. Nom. i): "We must not dare to say anything concerning the substantial Divinity except what has been divinely expressed to us by the sacred oracles." But in the Sacred Scripture we are not told that the Holy Ghost proceeds from the Son; but only that He proceeds from the Father, as appears from Jn 15,26: "The Spirit of truth, Who proceeds from the Father." Therefore the Holy Ghost does not proceed from the Son.
2. Further, In the creed of the council of Constantinople (Can. vii) we read: "We believe in the Holy Ghost, the Lord and Life-giver, who proceeds from the Father; with the Father and the Son to be adored and glorified." Therefore it should not be added in our Creed that the Holy Ghost proceeds from the Son; and those who added such a thing appear to be worthy of anathema.
3. Further, Damascene says (De Fide Orth. i): "We say that the Holy Ghost is from the Father, and we name Him the spirit of the Father; but we do not say that the Holy Ghost is from the Son, yet we name Him the Spirit of the Son." Therefore the Holy Ghost does not proceed from the Son.
4. Further, Nothing proceeds from that wherein it rests. But the Holy Ghost rests in the Son; for it is said in the legend of St. Andrew: "Peace be to you and to all who believe in the one God the Father, and in His only Son our Lord Jesus Christ, and in the one Holy Ghost proceeding from the Father, and abiding in the Son." Therefore the Holy Ghost does not proceed from the Son.
5. Further, the Son proceeds as the Word. But our breath [spiritus] does not seem to proceed in ourselves from our word. Therefore the Holy Ghost does not proceed from the Son.
6. Further, the Holy Ghost proceeds perfectly from the Father. Therefore it is superfluous to say that He proceeds from the Son.
7. Further "the actual and the possible do not differ in things perpetual" (Phys. iii, text 32), and much less so in God. But it is possible for the Holy Ghost to be distinguished from the Son, even if He did not proceed from Him. For Anselm says (De Process. Spir. Sancti, ii): "The Son and the Holy Ghost have their Being from the Father; but each in a different way; one by Birth, the other by Procession, so that they are thus distinct from one another." And further on he says: "For even if for no other reason were the Son and the Holy Ghost distinct, this alone would suffice." Therefore the Holy Spirit is distinct from the Son, without proceeding from Him.
On the contrary Athanasius says: "The Holy Ghost is from the Father and the Son; not made, nor created, nor begotten, but proceeding."
I answer that It must be said that the Holy Ghost is from the Son. For if He were not from Him, He could in no wise be personally distinguished from Him; as appears from what has been said above (Question , Article ; Question , Article ). For it cannot be said that the divine Persons are distinguished from each other in any absolute sense; for it would follow that there would not be one essence of the three persons: since everything that is spoken of God in an absolute sense, belongs to the unity of essence. Therefore it must be said that the divine persons are distinguished from each other only by the relations. Now the relations cannot distinguish the persons except forasmuch as they are opposite relations; which appears from the fact that the Father has two relations, by one of which He is related to the Son, and by the other to the Holy Ghost; but these are not opposite relations, and therefore they do not make two persons, but belong only to the one person of the Father. If therefore in the Son and the Holy Ghost there were two relations only, whereby each of them were related to the Father, these relations would not be opposite to each other, as neither would be the two relations whereby the Father is related to them. Hence, as the person of the Father is one, it would follow that the person of the Son and of the Holy Ghost would be one, having two relations opposed to the two relations of the Father. But this is heretical since it destroys the Faith in the Trinity. Therefore the Son and the Holy Ghost must be related to each other by opposite relations. Now there cannot be in God any relations opposed to each other, except relations of origin, as proved above (Question , Article ). And opposite relations of origin are to be understood as of a "principle," and of what is "from the principle." Therefore we must conclude that it is necessary to say that either the Son is from the Holy Ghost; which no one says; or that the Holy Ghost is from the Son, as we confess.
Furthermore, the order of the procession of each one agrees with this conclusion. For it was said above (Question , Articles ,4; Question , Article ), that the Son proceeds by the way of the intellect as Word, and the Holy Ghost by way of the will as Love. Now love must proceed from a word. For we do not love anything unless we apprehend it by a mental conception. Hence also in this way it is manifest that the Holy Ghost proceeds from the Son.
We derive a knowledge of the same truth from the very order of nature itself. For we nowhere find that several things proceed from one without order except in those which differ only by their matter; as for instance one smith produces many knives distinct from each other materially, with no order to each other; whereas in things in which there is not only a material distinction we always find that some order exists in the multitude produced. Hence also in the order of creatures produced, the beauty of the divine wisdom is displayed. So if from the one Person of the Father, two persons proceed, the Son and the Holy Ghost, there must be some order between them. Nor can any other be assigned except the order of their nature, whereby one is from the other. Therefore it cannot be said that the Son and the Holy Ghost proceed from the Father in such a way as that neither of them proceeds from the other, unless we admit in them a material distinction; which is impossible.
Hence also the Greeks themselves recognize that the procession of the Holy Ghost has some order to the Son. For they grant that the Holy Ghost is the Spirit "of the Son"; and that He is from the Father "through the Son." Some of them are said also to concede that "He is from the Son"; or that "He flows from the Son," but not that He proceeds; which seems to come from ignorance or obstinacy. For a just consideration of the truth will convince anyone that the word procession is the one most commonly applied to all that denotes origin of any kind. For we use the term to describe any kind of origin; as when we say that a line proceeds from a point, a ray from the sun, a stream from a source, and likewise in everything else. Hence, granted that the Holy Ghost originates in any way from the Son, we can conclude that the Holy Ghost proceeds from the Son.
Reply to Objection: 1. We ought not to say about God anything which is not found in Holy Scripture either explicitly or implicitly. But although we do not find it verbally expressed in Holy Scripture that the Holy Ghost proceeds from the Son, still we do find it in the sense of Scripture, especially where the Son says, speaking of the Holy Ghost, "He will glorify Me, because He shall receive of Mine" (Jn 16,14). It is also a rule of Holy Scripture that whatever is said of the Father, applies to the Son, although there be added an exclusive term; except only as regards what belongs to the opposite relations, whereby the Father and the Son are distinguished from each other. For when the Lord says, "No one knoweth the Son, but the Father," the idea of the Son knowing Himself is not excluded. So therefore when we say that the Holy Ghost proceeds from the Father, even though it be added that He proceeds from the Father alone, the Son would not thereby be at all excluded; because as regards being the principle of the Holy Ghost, the Father and the Son are not opposed to each other, but only as regards the fact that one is the Father, and the other is the Son.
2. In every council of the Church a symbol of faith has been drawn up to meet some prevalent error condemned in the council at that time. Hence subsequent councils are not to be described as making a new symbol of faith; but what was implicitly contained in the first symbol was explained by some addition directed against rising heresies. Hence in the decision of the council of Chalcedon it is declared that those who were congregated together in the council of Constantinople, handed down the doctrine about the Holy Ghost, not implying that there was anything wanting in the doctrine of their predecessors who had gathered together at Nicaea, but explaining what those fathers had understood of the matter. Therefore, because at the time of the ancient councils the error of those who said that the Holy Ghost did not proceed from the Son had not arisen, it was not necessary to make any explicit declaration on that point; whereas, later on, when certain errors rose up, another council [*Council of Rome, under Pope Damasus] assembled in the west, the matter was explicitly defined by the authority of the Roman Pontiff, by whose authority also the ancient councils were summoned and confirmed. Nevertheless the truth was contained implicitly in the belief that the Holy Ghost proceeds from the Father.
3. The Nestorians were the first to introduce the error that the Holy Ghost did not proceed from the Son, as appears in a Nestorian creed condemned in the council of Ephesus. This error was embraced by Theodoric the Nestorian, and several others after him, among whom was also Damascene. Hence, in that point his opinion is not to be held. Although, too, it has been asserted by some that while Damascene did not confess that the Holy Ghost was from the Son, neither do those words of his express a denial thereof.
4. When the Holy Ghost is said to rest or abide in the Son, it does not mean that He does not proceed from Him; for the Son also is said to abide in the Father, although He proceeds from the Father. Also the Holy Ghost is said to rest in the Son as the love of the lover abides in the beloved; or in reference to the human nature of Christ, by reason of what is written: "On whom thou shalt see the Spirit descending and remaining upon Him, He it is who baptizes" (Jn 1,33).
5. The Word in God is not taken after the similitude of the vocal word, whence the breath [spiritus] does not proceed; for it would then be only metaphorical; but after the similitude of the mental word, whence proceeds love.
6. For the reason that the Holy Ghost proceeds from the Father perfectly, not only is it not superfluous to say He proceeds from the Son, but rather it is absolutely necessary. Forasmuch as one power belongs to the Father and the Son; and because whatever is from the Father, must be from the Son unless it be opposed to the property of filiation; for the Son is not from Himself, although He is from the Father.
7. The Holy Ghost is distinguished from the Son, inasmuch as the origin of one is distinguished from the origin of the other; but the difference itself of origin comes from the fact that the Son is only from the Father, whereas the Holy Ghost is from the Father and the Son; for otherwise the processions would not be distinguished from each other, as explained above, and in Question .
Objection: 1. It would seem that the Holy Ghost does not proceed from the Father through the Son. For whatever proceeds from one through another, does not proceed immediately. Therefore, if the Holy Ghost proceeds from the Father through the Son, He does not proceed immediately; which seems to be unfitting.
2. Further, if the Holy Ghost proceeds from the Father through the Son, He does not proceed from the Son, except on account of the Father. But "whatever causes a thing to be such is yet more so." Therefore He proceeds more from the Father than from the Son.
3. Further, the Son has His being by generation. Therefore if the Holy Ghost is from the Father through the Son, it follows that the Son is first generated and afterwards the Holy Ghost proceeds; and thus the procession of the Holy Ghost is not eternal, which is heretical.
4. Further, when anyone acts through another, the same may be said conversely. For as we say that the king acts through the bailiff, so it can be said conversely that the bailiff acts through the king. But we can never say that the Son spirates the Holy Ghost through the Father. Therefore it can never be said that the Father spirates the Holy Ghost through the Son.
On the contrary Hilary says (De Trin. xii): "Keep me, I pray, in this expression of my faith, that I may ever possess the Father---namely Thyself: that I may adore Thy Son together with Thee: and that I may deserve Thy Holy Spirit, who is through Thy Only Begotten."
I answer that Whenever one is said to act through another, this preposition "through" points out, in what is covered by it, some cause or principle of that act. But since action is a mean between the agent and the thing done, sometimes that which is covered by the preposition "through" is the cause of the action, as proceeding from the agent; and in that case it is the cause of why the agent acts, whether it be a final cause or a formal cause, whether it be effective or motive. It is a final cause when we say, for instance, that the artisan works through love of gain. It is a formal cause when we say that he works through his art. It is a motive cause when we say that he works through the command of another. Sometimes, however, that which is covered by this preposition "through" is the cause of the action regarded as terminated in the thing done; as, for instance, when we say, the artisan acts through the mallet, for this does not mean that the mallet is the cause why the artisan acts, but that it is the cause why the thing made proceeds from the artisan, and that it has even this effect from the artisan. This is why it is sometimes said that this preposition "through" sometimes denotes direct authority, as when we say, the king works through the bailiff; and sometimes indirect authority, as when we say, the bailiff works through the king.
Therefore, because the Son receives from the Father that the Holy Ghost proceeds from Him, it can be said that the Father spirates the Holy Ghost through the Son, or that the Holy Ghost proceeds from the Father through the Son, which has the same meaning.
Reply to Objection: 1. In every action two things are to be considered, the "suppositum" acting, and the power whereby it acts; as, for instance, fire heats through heat. So if we consider in the Father and the Son the power whereby they spirate the Holy Ghost, there is no mean, for this is one and the same power. But if we consider the persons themselves spirating, then, as the Holy Ghost proceeds both from the Father and from the Son, the Holy Ghost proceeds from the Father immediately, as from Him, and mediately, as from the Son; and thus He is said to proceed from the Father through the Son. So also did Abel proceed immediately from Adam, inasmuch as Adam was his father; and mediately, as Eve was his mother, who proceeded from Adam; although, indeed, this example of a material procession is inept to signify the immaterial procession of the divine persons.
2. If the Son received from the Father a numerically distinct power for the spiration of the Holy Ghost, it would follow that He would be a secondary and instrumental cause; and thus the Holy Ghost would proceed more from the Father than from the Son; whereas, on the contrary, the same spirative power belongs to the Father and to the Son; and therefore the Holy Ghost proceeds equally from both, although sometimes He is said to proceed principally or properly from the Father, because the Son has this power from the Father.
3. As the begetting of the Son is co-eternal with the begetter (and hence the Father does not exist before begetting the Son), so the procession of the Holy Ghost is co-eternal with His principle. Hence, the Son was not begotten before the Holy Ghost proceeded; but each of the operations is eternal.
4. When anyone is said to work through anything, the converse proposition is not always true. For we do not say that the mallet works through the carpenter; whereas we can say that the bailiff acts through the king, because it is the bailiff's place to act, since he is master of his own act, but it is not the mallet's place to act, but only to be made to act, and hence it is used only as an instrument. The bailiff is, however, said to act through the king, although this preposition "through" denotes a medium, for the more a "suppositum" is prior in action, so much the more is its power immediate as regards the effect, inasmuch as the power of the first cause joins the second cause to its effect. Hence also first principles are said to be immediate in the demonstrative sciences. Therefore, so far as the bailiff is a medium according to the order of the subject's acting, the king is said to work through the bailiff; but according to the order of powers, the bailiff is said to act through the king, forasmuch as the power of the king gives the bailiff's action its effect. Now there is no order of power between Father and Son, but only order of 'supposita'; and hence we say that the Father spirates through the Son; and not conversely.
Objection: 1. It would seem that the Father and the Son are not one principle of the Holy Ghost. For the Holy Ghost does not proceed from the Father and the Son as they are one; not as they are one in nature, for the Holy Ghost would in that way proceed from Himself, as He is one in nature with Them; nor again inasmuch as they are united in any one property, for it is clear that one property cannot belong to two subjects. Therefore the Holy Ghost proceeds from the Father and the Son as distinct from one another. Therefore the Father and the Son are not one principle of the Holy Ghost.
2. Further, in this proposition "the Father and the Son are one principle of the Holy Ghost," we do not designate personal unity, because in that case the Father and the Son would be one person; nor again do we designate the unity of property, because if one property were the reason of the Father and the Son being one principle of the Holy Ghost, similarly, on account of His two properties, the Father would be two principles of the Son and of the Holy Ghost, which cannot be admitted. Therefore the Father and the Son are not one principle of the Holy Ghost.
3. Further, the Son is not one with the Father more than is the Holy Ghost. But the Holy Ghost and the Father are not one principle as regards any other divine person. Therefore neither are the Father and the Son.
4. Further, if the Father and the Son are one principle of the Holy Ghost, this one is either the Father or it is not the Father. But we cannot assert either of these positions because if the one is the Father, it follows that the Son is the Father; and if the one is not the Father, it follows that the Father is not the Father. Therefore we cannot say that the Father and the Son are one principle of the Holy Ghost.
5. Further, if the Father and the Son are one principle of the Holy Ghost, it seems necessary to say, conversely, that the one principle of the Holy Ghost is the Father and the Son. But this seems to be false; for this word "principle" stands either for the person of the Father, or for the person of the Son; and in either sense it is false. Therefore this proposition also is false, that the Father and the Son are one principle of the Holy Ghost.
6. Further, unity in substance makes identity. So if the Father and the Son are the one principle of the Holy Ghost, it follows that they are the same principle; which is denied by many. Therefore we cannot grant that the Father and the Son are one principle of the Holy Ghost.
7. Further, the Father, Son and Holy Ghost are called one Creator, because they are the one principle of the creature. But the Father and the Son are not one, but two Spirators, as many assert; and this agrees also with what Hilary says (De Trin. ii) that "the Holy Ghost is to be confessed as proceeding from Father and Son as authors." Therefore the Father and the Son are not one principle of the Holy Ghost.
On the contrary Augustine says (De Trin. v, 14) that the Father and the Son are not two principles, but one principle of the Holy Ghost.
I answer that The Father and the Son are in everything one, wherever there is no distinction between them of opposite relation. Hence since there is no relative opposition between them as the principle of the Holy Ghost it follows that the Father and the Son are one principle of the Holy Ghost.
Some, however, assert that this proposition is incorrect: "The Father and the Son are one principle of the Holy Ghost," because, they declare, since the word "principle" in the singular number does not signify "person," but "property," it must be taken as an adjective; and forasmuch as an adjective cannot be modified by another adjective, it cannot properly be said that the Father and the Son are one principle of the Holy Ghost unless one be taken as an adverb, so that the meaning should be: They are one principle---that is, in one and the same way. But then it might be equally right to say that the Father is two principles of the Son and of the Holy Ghost---namely, in two ways. Therefore, we must say that, although this word "principle" signifies a property, it does so after the manner of a substantive, as do the words "father" and "son" even in things created. Hence it takes its number from the form it signifies, like other substantives. Therefore, as the Father and the Son are one God, by reason of the unity of the form that is signified by this word "God"; so they are one principle of the Holy Ghost by reason of the unity of the property that is signified in this word "principle."
Reply to Objection: 1. If we consider the spirative power, the Holy Ghost proceeds from the Father and the Son as they are one in the spirative power, which in a certain way signifies the nature with the property, as we shall see later (ad 7). Nor is there any reason against one property being in two "supposita" that possess one common nature. But if we consider the "supposita" of the spiration, then we may say that the Holy Ghost proceeds from the Father and the Son, as distinct; for He proceeds from them as the unitive love of both.
2. In the proposition "the Father and the Son are one principle of the Holy Ghost," one property is designated which is the form signified by the term. It does not thence follow that by reason of the several properties the Father can be called several principles, for this would imply in Him a plurality of subjects.
3. It is not by reason of relative properties that we speak of similitude or dissimilitude in God, but by reason of the essence. Hence, as the Father is not more like to Himself than He is to the Son; so likewise neither is the Son more like to the Father than is the Holy Ghost.
4. These two propositions, "The Father and the Son are one principle which is the Father," or, "one principle which is not the Father," are not mutually contradictory; and hence it is not necessary to assert one or other of them. For when we say the Father and the Son are one principle, this word "principle" has not determinate supposition but rather it stands indeterminately for two persons together. Hence there is a fallacy of "figure of speech" as the argument concludes from the indeterminate to the determinate.
5. This proposition is also true:---The one principle of the Holy Ghost is the Father and the Son; because the word "principle" does not stand for one person only, but indistinctly for the two persons as above explained.
6. There is no reason against saying that the Father and the Son are the same principle, because the word "principle" stands confusedly and indistinctly for the two Persons together.
7.: Some say that although the Father and the Son are one principle of the Holy Ghost, there are two spirators, by reason of the distinction of "supposita," as also there are two spirating, because acts refer to subjects. Yet this does not hold good as to the name "Creator"; because the Holy Ghost proceeds from the Father and the Son as from two distinct persons, as above explained; whereas the creature proceeds from the three persons not as distinct persons, but as united in essence. It seems, however, better to say that because spirating is an adjective, and spirator a substantive, we can say that the Father and the Son are two spirating, by reason of the plurality of the "supposita" but not two spirators by reason of the one spiration. For adjectival words derive their number from the "supposita" but substantives from themselves, according to the form signified. As to what Hilary says, that "the Holy ghost is from the Father and the Son as His authors," this is to be explained in the sense that the substantive here stands for the adjective.
We now inquire concerning the name "Love," on which arise two points of inquiry:
(1) Whether it is the proper name of the Holy Ghost?
(2) Whether the Father and the Son love each other by the Holy Ghost?
Objection: 1. It would seem that "Love" is not the proper name of the Holy Ghost. For Augustine says (De Trin. xv, 17): "As the Father, Son and Holy Ghost are called Wisdom, and are not three Wisdoms, but one; I know not why the Father, Son and Holy Ghost should not be called Charity, and all together one Charity." But no name which is predicated in the singular of each person and of all together, is a proper name of a person. Therefore this name, "Love," is not the proper name of the Holy Ghost.
2. Further, the Holy Ghost is a subsisting person, but love is not used to signify a subsisting person, but rather an action passing from the lover to the beloved. Therefore Love is not the proper name of the Holy Ghost.
3. Further, Love is the bond between lovers, for as Dionysius says (Div. Nom. iv): "Love is a unitive force." But a bond is a medium between what it joins together, not something proceeding from them. Therefore, since the Holy Ghost proceeds from the Father and the Son, as was shown above (Question , Article ), it seems that He is not the Love or bond of the Father and the Son.
4. Further, Love belongs to every lover. But the Holy Ghost is a lover: therefore He has love. So if the Holy Ghost is Love, He must be love of love, and spirit from spirit; which is not admissible.
On the contrary Gregory says (Hom. xxx, in Pentecost.): "The Holy Ghost Himself is Love."
I answer that The name Love in God can be taken essentially and personally. If taken personally it is the proper name of the Holy Ghost; as Word is the proper name of the Son.
To see this we must know that since as shown above (Question , Articles ,3,4,5), there are two processions in God, one by way of the intellect, which is the procession of the Word, and another by way of the will, which is the procession of Love; forasmuch as the former is the more known to us, we have been able to apply more suitable names to express our various considerations as regards that procession, but not as regards the procession of the will. Hence, we are obliged to employ circumlocution as regards the person Who proceeds, and the relations following from this procession which are called "procession" and "spiration," as stated above (Question , Article , ad 3), and yet express the origin rather than the relation in the strict sense of the term. Nevertheless we must consider them in respect of each procession simply. For as when a thing is understood by anyone, there results in the one who understands a conception of the object understood, which conception we call word; so when anyone loves an object, a certain impression results, so to speak, of the thing loved in the affection of the lover; by reason of which the object loved is said to be in the lover; as also the thing understood is in the one who understands; so that when anyone understands and loves himself he is in himself, not only by real identity, but also as the object understood is in the one who understands, and the thing loved is in the lover. As regards the intellect, however, words have been found to describe the mutual relation of the one who understands the object understood, as appears in the word "to understand"; and other words are used to express the procession of the intellectual conception---namely, "to speak," and "word." Hence in God, "to understand" is applied only to the essence; because it does not import relation to the Word that proceeds; whereas "Word" is said personally, because it signifies what proceeds; and the term "to speak" is a notional term as importing the relation of the principle of the Word to the Word Himself. On the other hand, on the part of the will, with the exception of the words "dilection" and "love," which express the relation of the lover to the object loved, there are no other terms in use, which express the relation of the impression or affection of the object loved, produced in the lover by fact that he loves---to the principle of that impression, or "vice versa." And therefore, on account of the poverty of our vocabulary, we express these relations by the words "love" and "dilection": just as if we were to call the Word "intelligence conceived," or "wisdom begotten."
It follows that so far as love means only the relation of the lover to the object loved, "love" and "to love" are said of the essence, as "understanding" and "to understand"; but, on the other hand, so far as these words are used to express the relation to its principle, of what proceeds by way of love, and "vice versa," so that by "love" is understood the "love proceeding," and by "to love" is understood "the spiration of the love proceeding," in that sense "love" is the name of the person and "to love" is a notional term, as "to speak" and "to beget."
Reply to Objection: 1. Augustine is there speaking of charity as it means the divine essence, as was said above (here and Question , Article , ad 4).
2. Although to understand, and to will, and to love signify actions passing on to their objects, nevertheless they are actions that remain in the agents, as stated above (Question , Article ), yet in such a way that in the agent itself they import a certain relation to their object. Hence, love also in ourselves is something that abides in the lover, and the word of the heart is something abiding in the speaker; yet with a relation to the thing expressed by word, or loved. But in God, in whom there is nothing accidental, there is more than this; because both Word and Love are subsistent. Therefore, when we say that the Holy Ghost is the Love of the Father for the Son, or for something else; we do not mean anything that passes into another, but only the relation of love to the beloved; as also in the Word is imported the relation of the Word to the thing expressed by the Word.
3. The Holy Ghost is said to be the bond of the Father and Son, inasmuch as He is Love; because, since the Father loves Himself and the Son with one Love, and conversely, there is expressed in the Holy Ghost, as Love, the relation of the Father to the Son, and conversely, as that of the lover to the beloved. But from the fact that the Father and the Son mutually love one another, it necessarily follows that this mutual Love, the Holy Ghost, proceeds from both. As regards origin, therefore, the Holy Ghost is not the medium, but the third person in the Trinity; whereas as regards the aforesaid relation He is the bond between the two persons, as proceeding from both.
4. As it does not belong to the Son, though He understands, to produce a word, for it belongs to Him to understand as the word proceeding; so in like manner, although the Holy Ghost loves, taking Love as an essential term, still it does not belong to Him to spirate love, which is to take love as a notional term; because He loves essentially as love proceeding; but not as the one whence love proceeds.
Summa Th. I EN Qu.36 a.2
