e fear is not a
mortal sin.

Obj. 3: Further, mortal sin is a lapse not only from perfection but
also from a precept. But fear does not make one lapse from a precept,
but only from perfection; for a gloss on Deut. 20:8, "What man is
there that is fearful and fainthearted?" says: "We learn from this
that no man can take up the profession of contemplation or spiritual
warfare, if he still fears to be despoiled of earthly riches."
Therefore fear is not a mortal sin.

_On the contrary,_ For mortal sin alone is the pain of hell due: and
yet this is due to the fearful, according to Apoc. 21:8, "But the
fearful and unbelieving and the abominable," etc., "shall have their
portion in the pool burning with fire and brimstone which is the
second death." Therefore fear is a mortal sin.

_I answer that,_ As stated above (A. 1), fear is a sin through being
inordinate, that is to say, through shunning what ought not to be
shunned according to reason. Now sometimes this inordinateness of
fear is confined to the sensitive appetites, without the accession of
the rational appetite's consent: and then it cannot be a mortal, but
only a venial sin. But sometimes this inordinateness of fear reaches
to the rational appetite which is called the will, which deliberately
shuns something against the dictate of reason: and this
inordinateness of fear is sometimes a mortal, sometimes a venial sin.
For if a man through fear of the danger of death or of any other
temporal evil is so disposed as to do what is forbidden, or to omit
what is commanded by the Divine law, such fear is a mortal sin:
otherwise it is a venial sin.

Reply Obj. 1: This argument considers fear as confined to the
sensuality.

Reply Obj. 2: This gloss also can be understood as referring to the
fear that is confined within the sensuality. Or better still we may
reply that a man is terrified with his whole heart when fear banishes
his courage beyond remedy. Now even when fear is a mortal sin, it may
happen nevertheless that one is not so wilfully terrified that one
cannot be persuaded to put fear aside: thus sometimes a man sins
mortally by consenting to concupiscence, and is turned aside from
accomplishing what he purposed doing.

Reply Obj. 3: This gloss speaks of the fear that turns man aside from
a good that is necessary, not for the fulfilment of a precept, but
for the perfection of a counsel. Such like fear is not a mortal sin,
but is sometimes venial: and sometimes it
