The Divine Names in St. Thomas and in the Pseudo-Denys

Et tamen deus, cum de illo nihil digne dici possit, admisit humanae vocis obsequium, et verbis nostris in laude sua gaudere nos voluit.

—Augustine, de Doct. Christ. I.vi

St. Thomas Aquinas, the Angelic Doctor, was obviously one of the most inno-

vative theological thinkers of the medieval period. But what is equally obvious is

that, perhaps unlike the majority of modern theologians, he had no desire to be

seen as innovative, and in fact saw innovation as something to avoid. For St.

Thomas, the project of theology must always be conducted within the boundaries

established by the church’s doctrinal tradition; any innovation, then—any attempt

to move beyond those boundaries or to decisively break with the past—would be

something very close to heresy. Continuity with the tradition, or at least a pretense

of such continuity, was and is the hallmark of catholic theology. And in the case of

St. Thomas, the theological importance of establishing continuity with the past, of

smoothing over potential contradictions, and of avoiding conspicuous innovation

was only strengthened by his own personal humility: he was a saint, after all, as

well as a professor, and by all accounts he was not motivated by any desire to make

a name for himself or to make a splash in the world of Catholic theology. But be-

cause of the value St. Thomas placed on theological continuity, it is often difficult to

detect exactly where his thought departs from his predecessors in the catholic theo-

logical tradition. If possible, he generally attempts to demonstrate why apparent

contradictions between his doctrines and theirs are actually no contradictions at all

(most of the responses to objections in the Summa Theologiae play this sort of con-

ciliatory role), and he is absolutely unwilling to score rhetorical points by striking an

antagonistic pose against figures who have taught otherwise (he dispatches the on-

tological argument, for example, without mentioning Anselm in connection with it1).

In his doctrine on language about God, therefore, one can expect that St. Thomas

will make no effort to criticize the position laid out in the pseudo-Dionysian treatise

On the Divine Names. For St. Thomas, the prestige of this work, and what was for

him the barely subapostolic authority of its writer, demand that any subsequent dis-

cussion of the subject take seriously what the pseudo-Denys had to say. It is a text

that may be wrestled with, but not rejected. That St. Thomas recognized the author-

ity of this text is clear, if only from the number of times he cites it in his own theo-

logical writing. But without directly criticizing the pseudo-Denys, or at least while

avoiding the appearance of such criticism, St. Thomas in fact proposes a doctrine

very different from that of the pseudo-Areopagite. St. Thomas does not announce

this, and I believe that he would say the pseudo-Dionysian position is not incorrect,

if properly understood—such irenic thinking is St. Thomas’s modus operandi. But

even if the difference between St. Thomas and the pseudo-Denys is no more than a

difference of emphasis, it is not a difference without consequence for theology. If

one wants to say that St. Thomas’s project is to establish a grammar for theology,

then one could say that he wants that grammar to allow us to say things which the

pseudo-Denys would not.

Before considering St. Thomas’s divergences from the pseudo-Dionysian

teaching, we should consider that teaching in itself, which, as a very ancient and

very prestigious teaching, would always have been in the back of St. Thomas’s mind

as he wrote about the names of God.

The pseudo-Denys’s position is heavily Platonic, or rather Plotinian. God is in-

finite, beyond our proper understanding, and so properly nameless. We can name

God from created things, he says, because God and the world are connected in a

double motion: the exitus by which things are created by God, and the reditus by

which they ever yearn to return to him. The things of this world, caused by God, re-

tain something of the Cause by which they came to be; as all things yearn for him,

they hint to us at their final goal. God is simultaneously the essential and final

cause of all that exists.2 But since creation is something God does, and since every-

thing God does must be an essential part of his nature (as a good Platonist, and a

good Christian, the pseudo-Denys believes in the simplicity of the Godhead), then it

would be impossible if creation did not reveal to us something about the Godhead

who is its origin and goal. And so the pseudo-Denys writes that

as Cause of all and transcending all, he is rightly nameless and yet has the names of everything that is. […] Certainly he is to be praised as being of all things the creator and originator, the one who brings them to completion, their preserver, their protector, and their home, the power which returns them to itself, and all this in the one single, irrepressible, and supreme act.3

In a word: what we know about God is what we know about how God relates to crea-

tures. Due to the finite and imperfect nature of all fallen things, this means that we

necessarily see through a glass darkly: the pseudo-Denys describes the image of

God in creation in overtly Platonic language, as a seal impression that does not per-

fectly represent the seal due to the imperfection of the wax.4

But for the pseudo-Denys, our knowledge about God from created things falls

short not only because these impressions are faulty. It is not that our knowledge

2 See, e.g., de Div. Nom. I.5 593d: Providence “is the Cause of everything,” and “everything has it for a destiny.” Translated in Colm Luibheid, Pseudo-Dionysius: The Complete Works (Mahwah, NJ: Paulist Press, 1987).3 ibid. I.7, 596cd4 ibid. II.6, cf. Plat. Timaeus 50c.

fails in spite of its basis in impressions of the divine nature; it fails precisely because

it is based merely in impressions of the divine nature. We know about God from

what we know about his relation to created things, but all we know about that rela-

tion is what we know about it in the created things. The pseudo-Denys is quite clear

that this knowledge does not “reveal” anything about God, who remains perfectly

hidden, but merely discloses something about God’s processions or emanations. Ul-

timately, the most that created things can tell us about God is that they are related

somehow to him:

When, for instance, we give the name of “God” to that transcen-dent hiddenness [adumbrated to us in our knowledge of created things], when we call it “life” or “being” or “light” or “Word,” what our minds lay hold of is in fact nothing other than certain activities apparent to us, activities which deify, cause being, bear life, and give wisdom.5

The full implications of this are quite far-reaching: to call God “God” means only “he

deifies”; to call God “being” means only “he causes to be,” &c. We know God as the

cause of things, but we know him only as the cause of things. One could say that,

according to the pseudo-Denys, no man may see the living God, though we may see

his signs of life. Or, to adopt an idiom well-suited to the pseudo-Denys, we could say

that we sit on the floor of Plato’s Cave, seeing only the shadows and never the fire,

and by the word “fire,” signifying nothing more than “that which casts shadow.”

God is unknown not only in that he is greater than anything we might know about

him, but also in that he is other than anything we might know about him. There is,

so to speak, a sort of phenomena/noumena distinction in the thought of the pseudo-

Areopagite: even if we can see manifestations or emanations of the divine myster-

ies, nevertheless “their actual nature, what they are ultimately in their own source

and ground, is beyond all intellect and all being and all knowledge.”6

Page 5: de Divinis Nominibus

Gallagher 5

In this light, it makes perfect sense that the pseudo-Denys considers the

Good, more so than Being or Truth or Wisdom or any other name, to be the preemi-

nent name of God. The Good, he argues, is diffusivum sui,7 constantly giving out

more of itself, and never so perfectly communicated that there is not more of it to

be received. The good diffuses itself without limit, and constantly makes itself more

manifest; it is, therefore, the best name we can have for a God whom we know only

through the manifestation of his activities, a God whom we know only “phenome-

nally,” and never “noumenally” (if it is permitted to abuse Kantian language to

make a point). For the pseudo-Denys, since the emanations of the Godhead tell us

nothing about the Godhead who emanates (except that he emanates), the name of

the self-emanating Good is obviously the most appropriate one our minds can con-

ceive of. Accordingly, the pseudo-Denys gives Goodness priority even over Being.8

Being, as something which is manifested to us, must, for him, be inferior to the in-

finitely unknowable Godhead that manifests it. Thus the Good, the “first name” of

God, “tells of the universal Providence of the one God, while the other names [“Be-

ing,” “Life,” “Wisdom,” &c.] reveal general ways in which he acts providentially.”9

But ultimately, these names are names not of God himself, but of his Providence, of

his action: we name God from what we know of what he does outside himself.

For the pseudo-Denys, God as he is in himself is utterly secret. The one who

would truly know God, he says, must cast away all knowledge about God, and finally

7 ibid., IV.1, 693b, about the Good: “It sends the rays of its undivided goodness to everything with the capacity, such as this may be, to receive it.”8 see ibid., V.5, 820a: “He originated being, I mean absolute being, and with that as instru-ment he founded every type of existent.” (emphasis added). Also V.6, 820c: “The first gift therefore of the absolutely transcendent Goodness is the gift of being.” For the pseudo-Denys, the first principle of Being is something other than God; Being itself is not, as in St. Thomas, the essence of God’s life, but rather one of the first (and admittedly, one of the best and most important) of his emanations or “gifts.” Thus the pseudo-Denys, with nega-tive theologians everywhere, says in the first chapter of the Mystical Theology not only that God is “higher than any being,” but also that he is “beyond all being.” 9 de Div. Nom. V.2, 817a.

abandon knowing itself, before God will be truly known to him. And as regards this

knowledge of the “noumenal” God, beyond all knowledge of God’s “phenomenal”

processions and emanations, the pseudo-Denys’s language, never entirely sober,

becomes an absolute riot of paradox. One only knows God, he says, when “one is

united to the completely unknown by an inactivity of all knowledge, and knows be-

yond the mind by knowing nothing.”10 “The most divine knowledge of God,” and the

only knowledge of God which is knowledge of God himself, is “that which comes

through unknowing.”11 Just as our language is unequal to the task of describing God

as he is, so also is our knowledge unequal to the task of knowing God as he is. And

thus the pseudo-Dionysian account of language about God must always end with a

deafening apophatic silence.

And with this silence on the part of the pseudo-Denys, we also will fall silent

about the Dionysian doctrine of the divine names. This very brief account has been

enough to make clear the parts of his teaching where St. Thomas Aquinas diverges

from him. But first of all, one must not assume that St. Thomas intends explicitly or

implicitly to reject the pseudo-Denys’s account completely. He also believes, after

all, that “it is impossible for any created intellect to comprehend God,”12 and he ap-

provingly quotes the pseudo-Denys to the effect that through grace we come to

know God quasi ignoto, “as if something unknown.”13 Though St. Thomas is not fa-

mous as a negative theologian, he, like the Christian tradition generally, has no in-

tention of stating that God can ever be completely unmysterious. Whatever the dif-

English Dominicans, (New York: Benziger Brothers, 1947), vol. 1.13 ibid., q12.a13, ad 1um. Interestingly, he uses this quote both in the objection and in the re-ply thereto. This is, perhaps, a suggestion of the extent to which he sees the straightforward Dionysian teaching as something in need of further explanation. At any rate, as will become clear, St. Thomas quotes these words in a slightly different sense from that in which they were written.

Gallagher 7

ference is between St. Thomas and the pseudo-Denys, it’s something subtler than

that. Like the pseudo-Denys, he insists that we name God from creatures; 14 unlike

the pseudo-Denys, he believes the knowledge of God expressed in these names ap-

plies not only to God’s progressions or to his relations to the created world, but also

to his substance. St. Thomas argues that we name God from creatures, and thereby

name God as he is in himself.

This Thomistic position, like most Thomistic positions, is based on a series of

distinctions, in this case among the names that can without error be ascribed to

God. The first of these distinctions that Thomas makes is between the names of God

that are applied to him metaphorically, and those that are applied to him literally.

The metaphorical names of God, like all metaphors, are constructions which are un-

derstood to be literally false, although illustrative in some way. If I say that God is

my rock, I have not stated that God is actually a stone, but that some of the perfec-

tions of a rock—its durability, its strength, &c.—are also qualities I wish to predicate

of God. By the same token, there are some qualities of the rock—its material na-

ture, its dimensions—which could not be predicated of God without absurdity. In

contradistinction to these metaphorical names, there are names of God which St.

Thomas calls literal, which according to him involve nothing which would result in

absurdity when applied to God.15 Though our overview of the Dionysian account

above should make it clear that the pseudo-Denys would be reluctant to apply any

name literally to God himself, this Thomistic distinction between metaphorical and

literal names is paralleled by a Dionysian distinction between the names based on

14 ibid., q13.a1, corpus: “In this life we cannot know the essence of God, but we know him from creatures as their principle.” This formulation is more than superficially indebted to the pseudo-Denys, but as we will see, St. Thomas is here using the word “principle” in a way the pseudo-Denys would be unlikely to countenance.15 This distinction, and St. Thomas’s grounds for it, can be found succinctly in Summ. Theol. Ia.q13.a3.ad1um.

Gallagher 8

sense perception, discussion of which the pseudo-Denys postpones to his perhaps

nonexistent but at any rate missing Symbolic Theology, and so-called conceptual

names of God,” which seem to be the same as those of the divine names that St.

Thomas calls “literal.”16 This distinction, of course, is nothing to be surprised at. It is

obviously something else to call the Lord a “fighting man” (Ex. 15:3) than to refer to

him as the Almighty.

But if St. Thomas here establishes a distinction with which the pseudo-Denys

would most likely agree, he does it while making an argument that subtly distances

himself from the Dionysian position. St. Thomas, in raising an objection to the possi-

bility of naming god literally, cites the pseudo-Dionysian Celestial Hierarchy to the

effect that all names “are more truly withheld from God than given to him,” includ-

ing names such as “good, wise, and the like” that we might be most inclined to as-

cribe unambiguously to God.17 If this is the case (and this, of course, is why St.

Thomas raises it as an objection), not only can there be no literal names for God,

but metaphorical names for God are also rendered problematic; in accordance with

the pseudo-Denys’s thought as outlined above, we might metaphorically or even lit-

erally name a progression or emanation of God, but we may never presume to ap-

ply such a name to God in his own nature. St. Thomas, naturally, does not believe

that this objection cannot be overcome, but what is interesting is that he refers

again to the pseudo-Denys in his response, where he argues that

such [literal] names as these, as Dionysius shows, are denied of God [by the pseudo-Denys] for the reason that what the name signifies does not belong to him in the ordinary sense of its sig-nification, but in a more eminent way. Hence Dionysius also says that God is above substance and all life.18

16 de Div. Nom. I.8, 597b. This is also very like the distinction the pseudo-Denys makes else-where between “dissimilar similitudes” and “similar similitudes.”17 Summ. Theol. Ia.q13.a3, obj.2.18 ibid, q13.a3, ad 2um.

Page 9: de Divinis Nominibus

Gallagher 9

St. Thomas, that is, will allow the pseudo-Denys to deny the goodness or wisdom of

God only inasmuch as he argues that the pseudo-Denys actually means to say that

God’s goodness or wisdom is so much better or wiser than ours that it barely de-

serves the same name; that in refusing to predicate life and substance of God we

mean to indicate that God is actually more perfectly substantial and more wholly

living than we. This is true, and certainly ad mentem Thomae, as far as that goes,

but it seems like a very weak idea on which to base a thoroughgoing negative theol-

ogy like the pseudo-Denys’s: it reminds me of a time years ago when my young

brother, newly confident in his verbal skills, used to entertain himself by telling my

mother that her cooking was not good—since it was, after all, great. Such a denial,

at least as it seems to me, is just a backhanded affirmation: my mother’s cooking is

pretty good, however you want to say it. But we need not be concerned with such

cases here, since that kind of denial is manifestly not what the pseudo-Denys advo-

cates, at least not in On the Divine Names. The pseudo-Denys, as we have seen, ar-

gues not only that God is greater than what our language can handle, but also that

he is other than what our language can handle. He calls for silence, apophaticism,

and unknowing, not because language cannot say enough, but because language,

as far as he is concerned, ultimately leads in the wrong direction. It is for this rea-

son that the pseudo-Denys insists, in the very chapter of the Celestial Hierarchies

that St. Thomas quoted in the above objection, that metaphorical images “are actu-

ally no less defective than” conceptual names for God.19 Language, for the pseudo-

Denys, falls so short of God that there is very little point in comparing the value of

utterances about God. In his response to that Dionysian objection, however, St.

Thomas reinterprets the pseudo-Denys in such a way that the pseudo-Denys seems

to support St. Thomas’s own view of the question, a view that forms the basis for a

19 Coel. Hier. II.3, 140c. Also in Luibheid.

Page 10: de Divinis Nominibus

Gallagher 10

confident affirmative theology that seems to be completely at odds with the

pseudo-Dionysian theological project.

For reasons of theological continuity, St. Thomas tries to make it appear as if

the pseudo-Denys might support his argument. Even if the prospect of appropriat-

ing the Areopagite’s authority to St. Thomas’s arguments seems less admirable to a

modern than it would have to a medieval reader, the question still remains: since

St. Thomas’s doctrine on the divine names evidently does not come out of the

pseudo-Denys, where actually does it come from? On what grounds does St.

Thomas bridge the gap between what we see in creation and what we can say

about the divine essence in itself?

It should be emphasized, first of all, that St. Thomas believes that language

can bridge this gap, but not that the gap is thereby closed, or that created language

can be applied to the divine nature unproblematically. Indeed, the difference be-

tween their positions is very small. The pseudo-Denys argues that no name can sig-

nify the divine substance, because all names fall short of a full representation of

God. St. Thomas, on the other hand, argues that “these names signify the divine

substance, although they fall short of a full representation of him.”20 St. Thomas

makes this claim with full awareness that he goes against the pseudo-Denys. In the

article of his Summa treating on these substantial names of God, St. Thomas raises

an objection by citing the pseudo-Denys to the effect that the names of God are

named “according to the divine processions,” and “what expresses the procession

of anything does not signify its essence.”21 St. Thomas also seems to be referencing

the pseudo-Denys when he briefly considers an opinion that the names of God de-

20 Summ. Theol. Ia.q13.a2, corpus.21 ibid, q13.a2, obj. 2. This is what we have inadvisedly called the “phenomenal/noumenal” distinction in Denys’s thought.

Page 11: de Divinis Nominibus

Gallagher 11

rive merely from his causal and other relationships with his creatures.22 St. Thomas

rejects these reasons, on grounds that (like so much in his thought) have to do with

his understanding of the relation of creature to creator. For the pseudo-Denys, as

we have seen, to be created is to proceed from God, or to be emanated; that is, cre-

ation is understood primarily as separation from God.23 This understanding is com-

pletely in line with the thematic of creative exitus and erotic reditus that predomi-

nate in the pseudo-Denys’s thought, and for that matter can be found in some form

or another in any number of Christian thinkers. But this separation explains why for

the pseudo-Denys, though created things can certainly point in the direction of God,

they cannot actually lead us to him. But, in the context of his discussion of the di-

vine names, St. Thomas rejects this understanding of the relation between creator

and created, and offers an alternative:

God possesses in himself all the perfections of creatures, being Himself simply and universally perfect. Hence every creature represents him and is like him so far as it possesses some per-fection, yet it represents him not as something of the same species or genus, but as the excelling principle of whose form the effects fall short.24

This is not a narrative of emanation but of participation. Perfections, here, are not

like Platonic forms stamped upon recalcitrant matter, but rather more like Aris-

totelian forms, in which matter takes part. And so the perfections of God—the per-

fections that are God, since St. Thomas is also a believer in the simplicity of the

Godhead—are perfections that can also occur in creatures. The perfections of God,

22 ibid, q13.a2., corpus.23 N.B. This is not, in the pseudo-Denys, anything close to a Manichean view. He does not think that the world is evil or abandoned by God, but rather that creation exists as an ema-nation into time of a primal and eschatological unity. He emphasizes absolutely that cre-ation, though coming from God, is not God; and God, though before and behind everything in creation, is not creation. It probably would be better to call this something other than “creation’s separation from God,” but I can’t think of happier language that wouldn’t spoil the real (erotic) tension between procession and return that strikes me as such a prominent theme in his thought.24 Summ. Theol. Ia.q13.a2, corpus.

Page 12: de Divinis Nominibus

Gallagher 12

according to St. Thomas, are more, infinitely more, than any creaturely perfections.

But the way in which he understands the relation of creator and created allows him

to say that creaturely justice is a participation in divine justice, creaturely beauty is

a participation in divine beauty, and creaturely being is a participation in the pure

esse of God. Of course creatures represent their creator imperfectly, but inasmuch

as there are any perfections in creatures, it is correct, for St. Thomas, to say that

they are also the perfections of God. For “whatever good we attribute to creatures,

preexists in God.”25 For this reason, it is not a problem to name God from creaturely

perfections; the “processions” of God, inasmuch as Thomas thinks in such terms, do

in fact represent his essence, since every perfection he communicates into creation

is also a perfection that exists essentially in him. St. Thomas, then, believes in a

theological language which can never speak completely, but which can speak cor-

rectly. Unlike the pseudo-Denys, he believes human language is (or at least can

sometimes be) on the right track.

At this point, however, St. Thomas seems to have come dangerously close to

a very serious theological problem. In the article cited above, he argued not only

that the perfections of creatures can represent the perfections of God, but he also

argued that this representation does not happen according to “the same species or

genus.” But in this case, when the same words are not applied according to the

same species or genus, it would seem that they are applied equivocally. This would

not be a problem for metaphor, or for the always self-undermining theological lan-

guage of the pseudo-Denys, but it does seem to seriously threaten St. Thomas’s

project to defend a theological language capable of speaking literally about God.

And yet one can see why he needs to add this qualification; for if God and creatures

were described according to the same species and genus—that is, univocally—then

25 ibid., loc. cit.

Page 13: de Divinis Nominibus

Gallagher 13

the absolute distinction that St. Thomas (and almost all theological authorities)

placed between creature and Creator seems to have broken down. Confronted with

this dilemma, the pseudo-Denys chose equivocal language, and the consequent dis-

connection of all God-talk from God, rather than language that would blasphe-

mously reduce God to a being among beings. Confronted with the same dilemma,

St. Thomas’s response is to deny that it is a dilemma, and to argue for the existence

of a tertium quid—analogical language.26 Simply put, it means that though God is

not good in the same way that creatures are good, there is nonetheless a notion of

goodness that is somehow common to them both. The difference has to do with di-

vine simplicity and created complexity; the commonality, with participation. God

possesses his excellences simply, and so his goodness, his mercy, his justice, &c.

are all the same thing in his essence. Creatures, on the other hand, which are not

simple, possess their excellences in a complex way. And yet because of the partici-

pation of creatures in divine excellence, the same excellences are possessed (under

different metaphysical conditions) by God and creatures alike.

But the metaphysics of analogy are not really our concern here: it is paradox-

ical to advance the claim that creatures can take part in the life of a God in whom

there are no parts, but what Christian would dare to deny it? Our main concern here

is what analogical language allows St. Thomas to accomplish theologically. And it is

no small thing. We have seen that St. Thomas agrees with the pseudo-Denys that

all language about God is first creaturely language, which we then apply to God

with a greater or lesser degree of justification. But the crux of St. Thomas’s teach-

ing about analogical language is that some of the language we first learn about

creatures is actually already language about God.27 If the pseudo-Denys has pro-

26 ibid., q13.a527 ibid. q13.a6

Page 14: de Divinis Nominibus

Gallagher 14

posed for us a ladder of theological ascent, by which we ascend to less and less

concrete talk about God until we abandon the ladder, our language exhausted—if

that is a fair simile for the pseudo-Denys’s theology, then St. Thomas has given us a

ladder more like Jacob’s ladder, on which the angels both ascend and descend. By

metaphor, we use earthly things to point up to God; in analogy, we discover that the

divine perfections are already somehow present in and among creatures. When St.

Thomas, then, writes that through faith we are united to God as if to something un-

known (quasi ignoto), he adds that “we know him more fully according as many and

more excellent of His effects are demonstrated in us.”28 In principle, the pseudo-

Denys could agree with this; he believes, after all, that we can only know God

through his effects in creation. He could not, however, agree with it—in fact, he

would probably worry that what St. Thomas means by it is outright blasphemous.

For the pseudo-Denys, the quasi ignoto is the summary of our knowledge of God;

for St. Thomas it’s a kind of condition superadded to his description of the way in

which we know God. St. Thomas insists that God is knowable (even if not perfectly

comprehendible); he insists that the heavens declare the glory of God, and that the

invisible things of God are clearly known from the things that are made, and that

our human language is not inadequate to speaking of these.

And though the roots of this divergence in St. Thomas’s and the pseudo-

Denys’s theology, or in their theological styles, can be found in a small difference of

opinion regarding the relation of creation to Creator, the end results are extremely

different. Parvus error in principio magnus est in fine, as St. Thomas might point

out. And so St. Thomas produces a theological textbook, filled with precise defini-

tions and neat distinctions, while the pseudo-Denys tries to get us to understand

how the divine essence “is neither one nor oneness, divinity nor goodness,” and

28 ibid. q12.a13, ad 1um.

Page 15: de Divinis Nominibus

Gallagher 15

“falls neither within the predicate of nonbeing nor of being.”29 For his part, St.

Thomas considers the pseudo-Dionysian critique of affirmative theology, and con-

cludes that it is based on nothing more than a failure to properly understand the

modes of signification according to which a statement about God may be univocally

false and analogically true;30 he treats the critique as another problem to be solved

by an intellectual distinction within the affirmative system of his thought. A negative

theologian might see this style of theology as a very disappointing thing, a far cry

from the passionate yearning of the soul for God in unknowing. But to be fair, one

cannot say that St. Thomas is opposed to negative theology, or to mystic contem-

plation; at least at the end of his life, he knew something about divine mysteries

greater than language’s power to express. But for St. Thomas, it was no denigration

of mysticism to claim that that “true affirmative propositions can be formed about

God.”31

Although St. Thomas’s theology leaves room for mysticism, its style and its

affirmative nature were largely determined by the unmystical nature of his theologi-

cal project. For a monk like pseudo-Denys, devoted to a life of asceticism and to

yearning after the inexhaustible bliss of God, a theology which, cut off from crea-

turely references, strains in vain to capture mystic exaltation within the constraints

of language is the most suitable theology that could be imagined. Even St. Thomas

admits that the contemplative life is best, and he admits, most importantly of all,

that his teaching work is but “milk” when compared to the true “meat” of the Chris-

tian life.32 There is much more to know about God than can be revealed by an intel-

lectual edifice built of Aristotelian metaphysics and neat distinctions and analogies.

But St. Thomas was not a monk. He was a Dominican: if a monk’s duty is to weep, a

Dominican’s is to use language for the glory of God, to pray, to bless, and to preach,

and to teach others to do likewise. Language that can correctly be used of God is

among the basic prerequisites of these responsibilities. And for those of us who are

not monks, who are not prepared to yearn for God in silence, who want to know

what to say about God and how to pray to him, language something like St.

Thomas’s is absolutely necessary. To borrow another culinary metaphor,33 if our the-

ological diet might be blander without the paradoxical pastries of the pseudo-Denys

or even of Meister Eckhart, we would be seriously malnourished without healthy

portions of Thomistic brown bread.
