r. Now the object
of faith is a good, which is the First Truth, while the object of
fear is an evil, as stated above (I-II, Q. 42, A. 1). Again, acts
take their species from the object, according to what was stated
above (I-II, Q. 18, A. 2). Therefore faith is not a cause of fear.

_On the contrary,_ It is written (James 2:19): "The devils . . .
believe and tremble."

_I answer that,_ Fear is a movement of the appetitive power, as
stated above (I-II, Q. 41, A. 1). Now the principle of all appetitive
movements is the good or evil apprehended: and consequently the
principle of fear and of every appetitive movement must be an
apprehension. Again, through faith there arises in us an apprehension
of certain penal evils, which are inflicted in accordance with the
Divine judgment. In this way, then, faith is a cause of the fear
whereby one dreads to be punished by God; and this is servile fear.

It is also the cause of filial fear, whereby one dreads to be
separated from God, or whereby one shrinks from equalling oneself to
Him, and holds Him in reverence, inasmuch as faith makes us appreciate
God as an unfathomable and supreme good, separation from which is the
greatest evil, and to which it is wicked to wish to be equalled. Of
the first fear, viz. servile fear, lifeless faith is the cause, while
living faith is the cause of the second, viz. filial fear, because it
makes man adhere to God and to be subject to Him by charity.

Reply Obj. 1: Fear of God cannot altogether precede faith, because if
we knew nothing at all about Him, with regard to rewards and
punishments, concerning which faith teaches us, we should nowise fear
Him. If, however, faith be presupposed in reference to certain
articles of faith, for example the Divine excellence, then
reverential fear follows, the result of which is that man submits his
intellect to God, so as to believe in all the Divine promises. Hence
the text quoted continues: "And your reward shall not be made void."

Reply Obj. 2: The same thing in respect of contraries can be the
cause of contraries, but not under the same aspect. Now faith begets
hope, in so far as it enables us to appreciate the prize which God
awards to the just, while it is the cause of fear, in so far as it
makes us appreciate the punishments which He intends to inflict on
sinners.

Reply Obj. 3: The primary and formal object of faith is the good
which is the First Truth; but the material object of faith includes
a
