FOURTH ARTICLE [I, Q. 44, Art. 4]

Whether God Is the Final Cause of All Things?

Objection 1: It would seem that God is not the final cause of all

things. For to act for an end seems to imply need of the end. But God

needs nothing. Therefore it does not become Him to act for an end.

Obj. 2: Further, the end of generation, and the form of the thing

generated, and the agent cannot be identical (Phys. ii, text 70),

because the end of generation is the form of the thing generated. But

God is the first agent producing all things. Therefore He is not the

final cause of all things.

Obj. 3: Further, all things desire their end. But all things do not

desire God, for all do not even know Him. Therefore God is not the

end of all things.

Obj. 4: Further, the final cause is the first of causes. If,

therefore, God is the efficient cause and the final cause, it

follows that before and after exist in Him; which is impossible.

_On the contrary,_ It is said (Prov. 16:4): "The Lord has made all

things for Himself."

_I answer that,_ Every agent acts for an end: otherwise one thing would

not follow more than another from the action of the agent, unless it

were by chance. Now the end of the agent and of the patient considered

as such is the same, but in a different way respectively. For the

impression which the agent intends to produce, and which the patient

intends to receive, are one and the same. Some things, however, are

both agent and patient at the same time: these are imperfect agents,

and to these it belongs to intend, even while acting, the acquisition

of something. But it does not belong to the First Agent, Who is agent

only, to act for the acquisition of some end; He intends only to

communicate His perfection, which is His goodness; while every

creature intends to acquire its own perfection, which is the likeness

of the divine perfection and goodness. Therefore the divine goodness

is the end of all things.

Reply Obj. 1: To act from need belongs only to an imperfect agent,

which by its nature is both agent and patient. But this does not

belong to God, and therefore He alone is the most perfectly liberal

giver, because He does not act for His own profit, but only for His

own goodness.

Reply Obj. 2: The form of the thing generated is not the end of

generation, except inasmuch as it is the likeness of the form of the

generator, which intends to communicate its own likeness; otherwise

the form of the thing generated would be more noble than the

generator, since the end is more noble than the means to the end.

Reply Obj. 3: All things desire God as their end, when they desire

some good thing, whether this desire be intellectual or sensible, or

natural, i.e. without knowledge; because nothing is good and

desirable except forasmuch as it participates in the likeness to God.

Reply Obj. 4: Since God is the efficient, the exemplar and the final

cause of all things, and since primary matter is from Him, it follows

that the first principle of all things is one in reality. But this

does not prevent us from mentally considering many things in Him,

some of which come into our mind before others.
