Seven Deadly Sin: Gluttony
Derived from the Latin gluttire, meaning to gulp down or swallow, gluttony (Latin, gula) is the over-indulgence and over-consumption of anything to the point of waste.
In Christian religions, it is considered a sin because of the excessive desire for food, and its withholding from the needy. Because of these scripts, gluttony can be interpreted as selfishness; essentially placing concern with one's own interests above the well-being or interests of others.
Medieval church leaders like Thomas Aquinas took a more expansive view of gluttony, arguing that it could also include an obsessive anticipation of meals, and the constant eating of delicacies and excessively costly foods.
Gluttony seems to be a sin that Modern Christians like to ignore. We are often quick to label smoking and drinking as sins, but for some reason gluttony is accepted or at least tolerated. Many of the arguments used against smoking and drinking, such as health and addiction, apply equally to overeating. Many believers would not even consider having a glass of wine or smoking a cigarette but have no qualms about gorging themselves at the dinner table.
Whirlpool of Gluttony: Charybdis
Charybdis (or Kharybdis) was once a beautiful naiad and Goddess of the Tides. She is also the daughter of Poseidon and Gaia. She assumes the form of a huge bladder of a creature whose face is all mouth and whose arms and legs are flippers. She swallows a huge amount of water three times a day, before belching it back out again, creating large whirlpools capable of dragging a ship underwater.
Once a lovely maiden, Charybdis was loyal to her father, Poseidon the Ruler of the Sea, in his endless feud with Zeus. She rode the hungry tides after Poseidon stirred up a storm, directing them onto beaches, destroying entire villages, submerging fields and drowning forests, claiming all in her path for the sea. She claimed so much land for her father's kingdom that Zeus became enraged and changed her into a monster.
In mythology Charybdis lies on one side of a narrow channel. Opposite her is Scylla, another sea-monster. The sides of the strait are within an arrow shot of each other, and sailors attempting to avoid one of them will come in reach of the other. 'Between Scylla and Charybdis' thus means to have to choose between two dangers, either of which brings harm.
Not even the gods could save anyone who had approached near enough the devouring whirlpool that Charybdis' amazing activity formed.
Idioms such as "on the horns of a dilemma “,” between the devil and the deep blue sea and "between a rock and a hard place" express the same meaning of "having to choose between two evils".
One must indulge in some temptation one in while.
