om to those who suffer.

Obj. 2: Further, a martyr is a kind of witness. But witness is borne
to the truth alone. Now one is not called a martyr for bearing
witness to any truth, but only for witnessing to the Divine truth,
otherwise a man would be a martyr if he were to die for confessing a
truth of geometry or some other speculative science, which seems
ridiculous. Therefore faith alone is the cause of martyrdom.

Obj. 3: Further, those virtuous deeds would seem to be of most
account which are directed to the common good, since "the good of the
nation is better than the good of the individual," according to the
Philosopher (Ethic. i, 2). If, then, some other good were the cause
of martyrdom, it would seem that before all those would be martyrs
who die for the defense of their country. Yet this is not consistent
with Church observance, for we do not celebrate the martyrdom of
those who die in a just war. Therefore faith alone is the cause of
martyrdom.

_On the contrary,_ It is written (Matt. 5:10): "Blessed are they that
suffer persecution for justice' sake," which pertains to martyrdom,
according to a gloss, as well as Jerome's commentary on this passage.
Now not only faith but also the other virtues pertain to justice.
Therefore other virtues can be the cause of martyrdom.

_I answer that,_ As stated above (A. 4), martyrs are so called as
being witnesses, because by suffering in body unto death they bear
witness to the truth; not indeed to any truth, but to the truth which
is in accordance with godliness, and was made known to us by Christ:
wherefore Christ's martyrs are His witnesses. Now this truth is the
truth of faith. Wherefore the cause of all martyrdom is the truth of
faith.

But the truth of faith includes not only inward belief, but also
outward profession, which is expressed not only by words, whereby one
confesses the faith, but also by deeds, whereby a person shows that
he has faith, according to James 2:18, "I will show thee, by works,
my faith." Hence it is written of certain people (Titus 1:16): "They
profess that they know God but in their works they deny Him." Thus
all virtuous deeds, inasmuch as they are referred to God, are
professions of the faith whereby we come to know that God requires
these works of us, and rewards us for them: and in this way they can
be the cause of martyrdom. For this reason the Church celebrates the
martyrdom of Blessed John the Baptist, who suffered death, not for
