Ladder of Divine Ascent - Step Fourteen On Gluttony

We are all familiar enough with the urges of gluttony. But perhaps we have not stopped to fully consider the spiritual dangers of gluttony. This is something St. John spends a great deal of time discussing. His analysis is very helpful, for he opens up to us the interconnectedness of the spiritual life. St. John expresses the teaching of the Fathers in this way: "the belly is the cause of all human shipwreck."
Why? For two reasons: first, a gluttonous lifestyle feeds the passions which are inherent in man. Unrestrained eating habits spill over into an unrestrained lifestyle. The reason for this is clear: "Gluttony is the prince of the passions." St. John gives several examples. If you struggle with unclean thoughts, remember: "The mind of someone intemperate is filled with unclean longings." If you struggle with talking too much, remember: "The tongue flourishes where food is abundant." If you struggle with a lack of repentance, remember: "A full stomach dries up one's weeping." If you struggle with sexual sin, remember: "The man who looks after his belly and at the same time hopes to control the passion of fornication is like someone trying to put out a fire with oil." Of course, these are just a few examples of many. The point which St. John is making may be summarized as follows. The passions with which you struggle are energized by your gluttonous habits. Gluttony feeds your passions. Fasting takes away their nourishment.
The nature of the spiritual life is that all passion are interconnected. We cannot allow just one passion to be unrestrained. This is especially true of gluttony. If we are gluttonous we will be overwhelmed by other passions as well. And what is true in a negative way is also true in a positive way. If we struggle with gluttony and gain some victory, we also gain victory over our other passions.
But gluttony is not only dangerous because it unleashes our passions. The Fathers also teach that gluttony is dangerous because the demon of gluttony is the front man for other more dangerous demons. "You should remember," counsels St. John, "that frequently a demon can take up residence in your belly and keep a man from being satisfied, even after having devoured the whole of Egypt and after having drunk all of the Nile. After we have eaten, this demon goes off and sends the spirit of fornication against us, saying: `Get him now! Go after him. When his stomach is full, he will not put up much of a fight.' How seldom do we consider this when we are moved to eat. We have been taught to pamper our bodies and submit to their ever demand. Very few of us, however, question what spirit may be behind these desires.
