ed by us as we know it. But the
divine nature is unknown to us. Therefore this name "God" does not
signify the divine nature.

_On the contrary,_ Ambrose says (De Fide i) that "God" is a name of the
nature.

_I answer that,_ Whence a name is imposed, and what the name signifies
are not always the same thing. For as we know substance from its
properties and operations, so we name substance sometimes for its
operation, or its property; e.g. we name the substance of a stone from
its act, as for instance that it hurts the foot [loedit pedem]; but
still this name is not meant to signify the particular action, but the
stone's substance. The things, on the other hand, known to us in
themselves, such as heat, cold, whiteness and the like, are not named
from other things. Hence as regards such things the meaning of the
name and its source are the same.

Because therefore God is not known to us in His nature, but is made
known to us from His operations or effects, we name Him from these, as
said in A. 1; hence this name "God" is a name of operation so far as
relates to the source of its meaning. For this name is imposed from
His universal providence over all things; since all who speak of God
intend to name God as exercising providence over all; hence Dionysius
says (Div. Nom. ii), "The Deity watches over all with perfect
providence and goodness." But taken from this operation, this name
"God" is imposed to signify the divine nature.

Reply Obj. 1: All that Damascene says refers to providence; which is
the source of the signification of the name "God."

Reply Obj. 2: We can name a thing according to the knowledge we have
of its nature from its properties and effects. Hence because we can
know what stone is in itself from its property, this name "stone"
signifies the nature of the stone itself; for it signifies the
definition of stone, by which we know what it is, for the idea which
the name signifies is the definition, as is said in _Metaph._ iv. Now
from the divine effects we cannot know the divine nature in itself,
so as to know what it is; but only by way of eminence, and by way of
causality, and of negation as stated above (Q. 12, A. 12). Thus the
name "God" signifies the divine nature, for this name was imposed to
signify something existing above all things, the principle of all
things and removed from all things; for those who name God intend to
signify all this.
