Gluttony (From Lat. gluttire, to swallow, to gulp down), the excessive indulgence in food and drink.
The moral deformity discernible in this vice lies in its defiance of the order postulated by reason, which prescribes necessity as the measure of indulgence in eating and drinking.
This deordination may happen in five ways which are set forth in the scholastic verse: too soon, too expensively, too much, too eagerly, too daintily.
Clearly one who uses food or drink in such a way as to injure his health or impair their mental equipment is guilty of the sin of gluttony.
To eat or drink for the mere pleasure of the experience, and for that exclusively, is likewise to commit the sin of gluttony.
Gluttony is in general a venial sin in so far forth as it is an undue indulgence in a thing which is in itself neither good nor bad.
Of course it is obvious that a different estimate would have to be given of one so wedded to the pleasures of the table as to absolutely and without qualification live merely to eat and drink, so minded as to be of the number of those, described by the Apostle St. Paul, “whose god is their belly” (Philippians 3:19).
Such a one would be guilty of mortal sin.
“Spiritual gluttony” is the disposition of those who, in prayer and other acts of religion, are always in search of sensible sweetness; they are those who “will feel and taste God, as if he were palpable and accessible to them not only in Communion but in all their other acts of devotion.”
This is a very great imperfection and productive of great evils.
I still say of all, Envy is the most deadly of all, it was the primary source of Communism, which killed over 100 million people last century.
Also Nazism was based on envy of the British Empire, and that Germany wanted her colonies as well.
Sushi and a half-pint of hot sake on Friday night during Lent, Confession on Saturday afternoon, a big champagne breakfast (with bacon) at Le Peep Sunday morning before Mass. Ten bucks in the collection basket. Go home, watch TV, express disgust at all the homos and queers ruining the comedy shows. Yep, that about sums it up.
