Whether God Is Composed of Matter and Form?
Objection 1: It seems that God is composed of matter and form. For
whatever has a soul is composed of matter and form; since the soul is
the form of the body. But Scripture attributes a soul to God; for it
is mentioned in Hebrews (Heb. 10:38), where God says: "But My just man
liveth by faith; but if he withdraw himself, he shall not please My
soul." Therefore God is composed of matter and form.
Obj. 2: Further, anger, joy and the like are passions of the
composite. But these are attributed to God in Scripture: "The Lord was
exceeding angry with His people" (Ps. 105:40). Therefore God is
composed of matter and form.
Obj. 3: Further, matter is the principle of individualization.
But God seems to be individual, for He cannot be predicated of many.
Therefore He is composed of matter and form.
_On the contrary,_ Whatever is composed of matter and form is a body;
for dimensive quantity is the first property of matter. But God is not
a body as proved in the preceding Article; therefore He is not
composed of matter and form.
_I answer that,_ It is impossible that matter should exist in God.
First, because matter is in potentiality. But we have shown (Q. 2, A. 3)
that God is pure act, without any potentiality. Hence it is
impossible that God should be composed of matter and form. Secondly,
because everything composed of matter and form owes its perfection and
goodness to its form; therefore its goodness is participated, inasmuch
as matter participates the form. Now the first good and the
best--viz. God--is not a participated good, because the essential
good is prior to the participated good. Hence it is impossible that
God should be composed of matter and form. Thirdly, because every
agent acts by its form; hence the manner in which it has its form is
the manner in which it is an agent. Therefore whatever is primarily
and essentially an agent must be primarily and essentially form. Now
God is the first agent, since He is the first efficient cause. He is
therefore of His essence a form; and not composed of matter and form.
Reply Obj. 1: A soul is attributed to God because His acts
resemble the acts of a soul; for, that we will anything, is due to our
soul. Hence what is pleasing to His will is said to be pleasing to His
soul.
Reply Obj. 2: Anger and the like are attributed to God on
account of a similitude of effect. Thus, because to punish is properly
the act of an angry man, God's punishment is metaphorically spoken of
as His anger.
Reply Obj. 3: Forms which can be received in matter are
individualized by matter, which cannot be in another as in a subject
since it is the first underlying subject; although form of itself,
unless something else prevents it, can be received by many. But that
form which cannot be received in matter, but is self-subsisting, is
individualized precisely because it cannot be received in a subject;
and such a form is God. Hence it does not follow that matter exists in
God.
