(Note: The following is a presentation of the
classical Thomistic doctrine of philosophical
theology for those who are unacquainted with it.
Knowledge of the classical doctrine itself is
valuable for any student of philosophy. This branch
of philosophy is called Natural Theology or
Theodicy and discovers the First Efficient Cause
and the Last Final Cause of all things. This study
is a purely philosophical one, and draws no
arguments from revelation (although it makes
reference to Christian revelation at certain
points); it is a truly metaphysical study, for it
is a reasoned treatise on nonmaterial real Being,
from a traditional Christian perspective. Some of
this treatise is highly technical and an
acquaintance with Classical Thomistic ontology is
highly recommended before approaching this
subject.)

Part 2: The
Nature of God
A. Essence
and Nature
The essence of a thing is what
constitutes it. The essence of a thing is what is
expressed in a true definition of the thing.
A thing may be regarded in two ways:
- as an existible reality,
and
- as an understandable reality.
Hence, any reality may be defined in two
ways:
- either according to its being as an
existible thing, or
- according to its being as an understandable
thing.
Suppose we are define man. As an
existible thing man is a substantial compound of
body and soul; as a thing that can exist among
other things, man exists as body and soul. This is
a definition of man, and it is called a
physical definition. A definition
expresses an essence, and the physical
definition of man expresses the physical essence of
man, that is, "body and soul substantially
united."
But suppose we define man as an
understandable thing. We do not mean to
define him according to the mere viewpoint of the
mind; we mean to define him as a reality.
But we mean to make our definition of those
points of reality in man (not physical
parts like body and soul) which render him
intelligible. Now, how does an adequate mind or
understanding lay hold of the reality called
man?
- Well, first of all it knows man as some
thing.
- Further, it knows man as a substantial
thing, and as a complete substance; it knows man
as subsistent. The mind knows man as a
subsistent thing.
- But it knows him as distinct from such
subsistent things as pure spirits; for it knows
man as a bodily-subsistent-thing.
- And it knows man as other than mere bodies
like sticks and stones; for it knows man as a
living-bodily-subsistent-thing.
- And it knows man as something more than a
living substance such as a tree; for it knows
man as a
sentient-living-bodily-subsistent-thing.
- And it knows man as something more than a
sentient substance like a dog or cat; for it
knows man as endowed with intellect and will,
that is, it knows man as a
rational-sentient-living-bodily-subsistent-thing.
Notice that all the points the mind knows about
man as understandable are points of reality;
they are not points of the mind's view, they are
points of fact in man himself; yet they are not
physical parts. The six points of reality about man
that make him intelligible or understandable are:
thing, subsistent, bodily, living, sentient,
rational. And you may take any one of these as
predicate and say that man is such a thing:
man is subsistent; man is alive; man
is rational. Now the sum of all the points
of reality which render a thing understandable
constitutes the metaphysical essence of that
thing.
Thus the metaphysical essence of man is: "a
reality or thing that is subsistent, bodily,
living, sentient, and rational." Since the first
five of these points of reality in man (that is,
thing, subsistent, bodily,
living, sentient) make the
metaphysical essence of animal, we may
merely add the word rational to
animal, and we have, in shorter compass, the
metaphysical essence of man. The metaphysical
essence of man is expressed in the metaphysical
definition of man: "Man is a rational animal."
The physical essence of man is his
constitution as an existible thing; it is made up
of man's fundamental and indispensable physical
parts; it is constituted by man's body and
soul.
The metaphysical essence of man is the
sum of the points of reality about him that make
him understandable; the sum of points of reality
recognized by a mind that knows what man is;
this metaphysical essence of man is constituted of
animality and rationality.
Now, what we have said about the physical and
metaphysical essence of man is true of the physical
and metaphysical essence of anything. We
have used man only as an illustration. In
our present study we are to inquire into the
physical essence and the metaphysical essence of
God.
The nature of a thing is its essence
regarded as the root or source of its operations.
The nature of a thing is its working
essence. Thus, while we say that the
essence of a man is (physically considered)
his body and soul, we say that the nature of
man is his essence as operative. We say that
it is according to man's nature that he
thinks and wills; we say that it is natural
to man to walk and to speak, and so on.
Now, the items of perfection that belong to a
thing because it is of such a nature , are
called attributes of the thing. It is
essential (metaphysically) to man that he be
fundamentally equipped for reasoning and
willing; he has this fundamental equipment even as
a baby when he is unable to use it; he has this
equipment even if he be so mentally handicapped
that will never use it. But the actual ability to
use this fundamental equipment belongs only to man
when is sufficiently matured, when he is conscious,
when he is unprevented in its use.
But granted that a man is fully constituted in
being, that he is mature, awake, alert, unblocked
in the exercise of his powers, it will follow of
necessity that he is able actually to reason and
to use free will. This actual ability,
we say, belongs to his nature, his operative
essence; this ability follows upon that nature
because it is such a nature. Therefore this actual
ability is proper to man, it is to be
attributed to man: actual reasoning and
actual willing are attributes of man. An
attribute is, therefore, the normal and
necessary consequence of an essence fully
constituted in its working capacity, that is, of an
essence constituted as a nature. In brief, an
attribute is a perfection that belongs by natural
necessity to a nature.
We see, therefore, that an attribute (since it
belongs to a nature because this is such a
nature) is an index of the nature to which it
belongs. If we know the attributes of a thing, we
shall know by them the nature whence they flow, or
to which they necessarily belong. Therefore, in our
present study we shall investigate certain
attributes of God, so that we may know the
nature of God.
To sum up: Essence is that reality which
constitutes a thing as existible (physical
essence) or as understandable (metaphysical
essence). Nature is essence considered as the
source of operations. Attributes are perfections
that belong by necessity to a fully constituted and
unhampered nature.
B. The
Essence of God
1. The Physical Essence
of God
God is not a body; He is not made up of parts.
God is not a creature; He is not limited or
confined or in any way composed. Hence, the
physical essence of God is a unique physical
essence. We cannot illustrate it perfectly by
showing what the physical essence of some creature
is, and then drawing a comparison. But, since God
is "constituted" (to use an imperfect word) in His
being by Himself, and not as a sum of parts
or of distinct elements or perfections, it may
suffice to say that God's physical essence is his
infinite and indivisible being as pure
spirit. That is what God is an existing thing:
a Spirit infinitely perfect. More fully,
God's physical essence is defined as the one and
only infinite indivisible and all-perfect
Spirit.
Notice that we mention several
perfections in setting forth this physical
definition of God. We speak of the oneness
or unity of God; of His uniqueness
which which we indicate by the word "only"; of His
simplicity or indivisibility, for God
has no parts; of His full perfection; of His
infinity; of His spirituality.
Now, it must be always understood that in God
there is not only no distinction of parts (for He
has no parts), but there is no real distinction of
perfections; all that God has He is.
All these perfections are in reality one
with God and one with one another; all are one in
the Infinite Essence with which they are
identified, and of which they are but various
aspects taken by the finite mind.
2. The Metaphysical
Essence of God
That is called the metaphysical essence of God
which affords the mind its basic grasp of what
God means. Theologians have ever differed in
their opinion of what precisely is the point by
which a creatural mind lays hold of God as
understandable. Some had said that the fundamental
notion or idea which the mind grasps in knowing God
is His radical infinity; others have said
that it is His boundless knowing. But
others, with more show of reason, say that before
we think of God as infinite or as all-knowing, we
think of God as there. We think of Him as
existing. And we think of Him as existing
of Himself, or, in other words, we think of God
as Subsistent Being Itself. In this we
discern the metaphysical essence of God.
C. The
Attributes of God
An attribute, as we have learned, is a
perfection that belongs to a thing because the
thing is of such a nature. It belongs
to a nature. It flows from a nature fully
and perfectly constituted and unprevented in
function. Strictly speaking, God has no
attributes. What we call His attributes are
Himself regarded by our finite minds from
different angles. God is simple, indivisible, not
made of parts or elements. All that God has,
God is. But we must use such terms as we
can; we are finite and our language is not adequate
for expressing infinity with full perfection.
Therefore, as long as we know that what we call
God's attributes are not things other than God
which God merely possesses, we may use our
inadequate terminology as the only available
instrument for the expression of important
truths.
We have already mentioned many attributes of God
in this study. We have spoken of God's oneness or
unity, of His infinity, of His simplicity, of His
uniqueness, of His supreme intelligence, of His
supreme will, and of other divine perfections or
attributes. Here we mention these again, together
with some others. In studying the attributes of
God, we are directly studying the nature of
God.
1. Absolute Divine
Attributes
"Absolute" means "freed from all ifs, buts,
hows, whys, conditions." The absolute attributes of
God are those which belong to God as God, not to
God as Creator, or Preserver, or Governor, but to
God simply. Such are infinity, immensity,
immutability or changelessness, knowledge,
wisdom.
Absolute divine attributes are either positive
or negative.
- Positive divine attributes express
infinite perfection in God: life, wisdom,
understanding, will, etc.
- Negative divine attributes express
absence of imperfection in God: infinity
(which means that God is not limited);
indivisibility (which means that God is
not made up of parts); immutability
(which means that God is not changeable),
etc.
2. Relative Divine
Attributes
"Relative" means having a relation to, a
connection with, something else. Now, on the part
of God, who is infinite and self-sufficing,
there are no real relations whatever. But
creatures have essential relations with God, and
these are real. God's relative attributes
bring creatures into relation with Him; they do not
bring God into any real relations with creatures.
Relative attributes of God are, for example, His
power, as creating, preserving, providing,
governing the world and especially man; His
goodness to His creatures; His fidelity to His
word; His truthfulness, and so on.
In general, reason declares that since God is
the fulness of all perfection in infinite degree;
since He is Pure Actuality; since He is wholly
Self-sufficing; since He is without the shadow of
any imperfection, He has a attributes all pure
perfections in a way superior to that in which
perfections are possessed or can be possessed by
creatures. The technical way of expressing this
reasoned truth is this: God has all pure
perfections formally and eminently.
A pure or unmixed perfection is
one that involves no imperfection, such as life,
knowledge. A mixed perfection involves
imperfection, such as walking or reasoning. For it
is a perfection to be able to walk; but it is an
indication of limitation (hence an imperfection)
that a person must walk to reach another place and
cannot be there instantly without walking. So it is
a perfection to be able to reason out a truth; but
it is an imperfection that one must think it out
and cannot see it at once without mental labor. We
say that mixed perfections are in God
virtually; that is, the equivalent of all
that is perfect about them belongs to God
eminently. Thus, God who knows all things
comprehensively (in such a way as to perfectly
possess all possible knowledge about them) has no
need of reasoning, that is, of studying
things out; but He has all that such study or
reasoning could possibly give; he has all
knowledge; therefore we say that he has reasoning
virtually or equivalently.
Now, the proof of all the perfections which can
be listed as attributes of God rests upon the
perfection of God in His metaphysical essence as
Subsistent Being Itself. For such a Being is
unconferred, unreceived, and hence not limited.
Being that is received is received in a
measure, Being unreceived must be unlimited,
for only a cause can limit being as only a
cause can confer it. So Being unreceived,
unconferred, is being uncaused and unlimited. It is
Infinite Being.
Out of God's essence as Subsistent Being Itself
appears the fundamental attribute of
infinity. Upon infinity, as upon their
proximate foundation (and their proof) rest the
other divine attributes. Thus God is infinite or
unlimited in time; He is eternal; He has the
attribute of eternity; and this eternity is
not limited or measured by days or hours or
centuries; it has no succession (for this
would involve limitation); it is an everlasting
now, without past or future.
And God, as infinite, is unlimited by place; He
is immense or immeasurable, not having size,
which, however large, is a limitation. God thus has
the attribute of immensity, of not being
contained in limits of measurement or dimensions.
And similarly God has the attribute, on this score,
of omnipresence or ubiquity; God is
everywhere, for place cannot shut Him out
any more than it can enclose Him.
And infinity involves immutability or
changelessness in God, for any change means
a loss and a gain, and a loss means a limit now,
while a gain means a limit before the gain was
made. Infinity in God means that he is not limited
in knowledge, in wisdom, in
power, in any perfection. Thus, infinity in
God means simply that God is all-perfect.
And since personality (that is substantial
personality) is a high perfection, it must be in
God in eminent degree. Human reason thus concludes
inevitably that God is a personal God, not a
"Cosmic Force" or an "Unconscious Absolute."
