Whether Gluttony Is a Mortal Sin?
Objection 1: It would seem that gluttony is not a mortal sin. For
every mortal sin is contrary to a precept of the Decalogue: and this,
apparently, does not apply to gluttony. Therefore gluttony is not a
mortal sin.
Obj. 2: Further, every mortal sin is contrary to charity, as stated
above (Q. 132, A. 3). But gluttony is not opposed to charity, neither
as regards the love of God, nor as regards the love of one's
neighbor. Therefore gluttony is never a mortal sin.
Obj. 3: Further, Augustine says in a sermon on Purgatory [*Cf.
Append. to St. Augustine's works: Serm. civ (xli, de sanctis)]:
"Whenever a man takes more meat and drink than is necessary, he
should know that this is one of the lesser sins." But this pertains
to gluttony. Therefore gluttony is accounted among the lesser, that
is to say venial, sins.
Obj. 4: _On the contrary,_ Gregory says (Moral. xxx, 18): "As long as
the vice of gluttony has a hold on a man, all that he has done
valiantly is forfeited by him: and as long as the belly is
unrestrained, all virtue comes to naught." But virtue is not done
away save by mortal sin. Therefore gluttony is a mortal sin.
_I answer that,_ As stated above (A. 1), the vice of gluttony
properly consists in inordinate concupiscence. Now the order of
reason in regulating the concupiscence may be considered from two
points of view. First, with regard to things directed to the end,
inasmuch as they may be incommensurate and consequently
improportionate to the end; secondly, with regard to the end itself,
inasmuch as concupiscence turns man away from his due end.
Accordingly, if the inordinate concupiscence in gluttony be found to
turn man away from the last end, gluttony will be a mortal sin. This
is the case when he adheres to the pleasure of gluttony as his end,
for the sake of which he contemns God, being ready to disobey God's
commandments, in order to obtain those pleasures. On the other hand,
if the inordinate concupiscence in the vice of gluttony be found to
affect only such things as are directed to the end, for instance when
a man has too great a desire for the pleasures of the palate, yet
would not for their sake do anything contrary to God's law, it is a
venial sin.
Reply Obj. 1: The vice of gluttony becomes a mortal sin by turning
man away from his last end: and accordingly, by a kind of reduction,
it is opposed to the precept of hallowing the sabbath, which commands
us to rest in our last end. For mortal sins are not all directly
opposed to the precepts of the Decalogue, but only those which
contain injustice: because the precepts of the Decalogue pertain
specially to justice and its parts, as stated above (Q. 122, A. 1).
Reply Obj. 2: In so far as it turns man away from his last end,
gluttony is opposed to the love of God, who is to be loved, as our
last end, above all things: and only in this respect is gluttony a
mortal sin.
Reply Obj. 3: This saying of Augustine refers to gluttony as denoting
inordinate concupiscence merely in regard of things directed to the
end.
Reply Obj. 4: Gluttony is said to bring virtue to naught, not so much
on its own account, as on account of the vices which arise from it.
For Gregory says (Pastor. iii, 19): "When the belly is distended by
gluttony, the virtues of the soul are destroyed by lust."
