FOURTH ARTICLE [I-II, Q. 51, Art. 4]

Whether Any Habits Are Infused in Man by God?

Objection 1: It would seem that no habit is infused in man by God.

For God treats all equally. If therefore He infuses habits into some,

He would infuse them into all: which is clearly untrue.

Obj. 2: Further, God works in all things according to the mode which

is suitable to their nature: for "it belongs to Divine providence to

preserve nature," as Dionysius says (Div. Nom. iv). But habits are

naturally caused in man by acts, as we have said above (A. 2).

Therefore God does not cause habits to be in man except by acts.

Obj. 3: Further, if any habit be infused into man by God, man can by

that habit perform many acts. But "from those acts a like habit is

caused" (Ethic. ii, 1, 2). Consequently there will be two habits of

the same species in the same man, one acquired, the other infused.

Now this seems impossible: for the two forms of the same species

cannot be in the same subject. Therefore a habit is not infused into

man by God.

_On the contrary,_ it is written (Ecclus. 15:5): "God filled him with

the spirit of wisdom and understanding." Now wisdom and understanding

are habits. Therefore some habits are infused into man by God.

_I answer that,_ Some habits are infused by God into man, for two

reasons.

The first reason is because there are some habits by which man is

disposed to an end which exceeds the proportion of human nature,

namely, the ultimate and perfect happiness of man, as stated above

(Q. 5, A. 5). And since habits need to be in proportion with that to

which man is disposed by them, therefore is it necessary that those

habits, which dispose to this end, exceed the proportion of human

nature. Wherefore such habits can never be in man except by Divine

infusion, as is the case with all gratuitous virtues.

The other reason is, because God can produce the effects of second

causes, without these second causes, as we have said in the First

Part (Q. 105, A. 6). Just as, therefore, sometimes, in order to show

His power, He causes health, without its natural cause, but which

nature could have caused, so also, at times, for the manifestation of

His power, He infuses into man even those habits which can be caused

by a natural power. Thus He gave to the apostles the science of the

Scriptures and of all tongues, which men can acquire by study or by

custom, but not so perfectly.

Reply Obj. 1: God, in respect of His Nature, is the same to all, but

in respect of the order of His Wisdom, for some fixed motive, gives

certain things to some, which He does not give to others.

Reply Obj. 2: That God works in all according to their mode, does not

hinder God from doing what nature cannot do: but it follows from this

that He does nothing contrary to that which is suitable to nature.

Reply Obj. 3: Acts produced by an infused habit, do not cause a

habit, but strengthen the already existing habit; just as the

remedies of medicine given to a man who is naturally health, do not

cause a kind of health, but give new strength to the health he had

before.
