God is everywhere by essence, power, and presence?

(4) Whether to be everywhere belongs to God alone?

FIRST ARTICLE [I, Q. 8, Art. 1]

Whether God Is in All Things?

Objection 1: It seems that God is not in all things. For what is above
all things is not in all things. But God is above all, according to
the Psalm (Ps. 112:4), "The Lord is high above all nations," etc.
Therefore God is not in all things.

Obj. 2: Further, what is in anything is thereby contained. Now
God is not contained by things, but rather does He contain them.
Therefore God is not in things but things are rather in Him. Hence
Augustine says (Octog. Tri. Quaest. qu. 20), that "in Him things are,
rather than He is in any place."

Obj. 3: Further, the more powerful an agent is, the more extended
is its action. But God is the most powerful of all agents. Therefore
His action can extend to things which are far removed from Him; nor is
it necessary that He should be in all things.

Obj. 4: Further, the demons are beings. But God is not in the
demons; for there is no fellowship between light and darkness (2 Cor.
6:14). Therefore God is not in all things.

_On the contrary,_ A thing is wherever it operates. But God operates in
all things, according to Isa. 26:12, "Lord . . . Thou hast wrought all
our works in [Vulg.: 'for'] us." Therefore God is in all things.

_I answer that,_ God is in all things; not, indeed, as part of their
essence, nor as an accident, but as an agent is present to that upon
which it works. For an agent must be joined to that wherein it acts
immediately and touch it by its power; hence it is proved in Phys. vii
that the thing moved and the mover must be joined together. Now since
God is very being by His own essence, created being must be His proper
effect; as to ignite is the proper effect of fire. Now God causes this
effect in things not only when they first begin to be, but as long as
they are preserved in being; as light is caused in the air by the sun
as long as the air remains illuminated. Therefore as long as a thing
has being, God must be present to it, according to its mode of being.
But being is innermost in each thing and most fundamentally inherent
in all things since it is formal in respect of everything found in a
thing, as was shown above (Q. 7, A. 1). Hence it must be that God
is in all things, and innermostly.

Reply Obj. 1: God is above all things by the excellence of His
nature;
