A recent report highlighted the problem of obesity in our society. The percentage of British adults who are overweight has risen by 11 per cent since 1993 to a whopping 64 per cent of the population, with almost one in four British adults classified as obese. In the USA it is even worse with 36 per cent of people classified as obese. And that has a knock-on effect on an already creaking NHS and healthcare systems elsewhere in the western world. The bill for the taxpayer for obesity is rising to unsustainable levels.  

There are many causes of obesity, some of them physiological, some genetic, some economic, with poverty often linked to poor diet. Eating healthily costs. Yet Christianity has always seen a spiritual side to the problem, relating to our relationship with food. As part of this diagnosis, Christian moralists have typically called out the sin of gluttony. 

Strange though it may seem, in the earliest lists of the deadly sins, gluttony used to head the list as the worst of them all. Pope Gregory in the sixth century wrote: “unless we first tame the enemy dwelling within us, namely our gluttonous appetite, we have not even stood up to engage in the spiritual combat.”  

Later assessment of the rank of gluttony in the list of deadly sins has taken a kinder view. Thomas Aquinas was easier on gluttons, because, for him, like lust, overeating mainly concerns the body rather than the soul, and as we have to feed ourselves anyway, it is understandable and less serious than the other sins. When Dante’s pilgrim arrives in hell, he finds the gluttons in the third circle of upper hell, not far from the top, tantalisingly within sight of the most succulent tree whose “crop of tempting fruit ambrosial odours spread”, but unable to climb to taste them. For him, gluttons are certainly better than the prideful, the envious, wrathful, slothful or covetous. The only sin that seems less harmful to him is lust.   

Our image-conscious society tends to look down on people who are overweight. Yet gluttony denies a simple rule that the fat are sinful and the thin are virtuous. When we think of gluttony, we maybe think of stuffing food into our mouths with no thought of tomorrow, over-indulgence to a huge degree. Yet the sin of gluttony has always been seen as wider than that, including that fastidiousness about food that obsesses over what you can and cannot eat. C.S. Lewis writes about the kind of old lady who simply asks for ‘a cup of tea, weak but not too weak, the teeniest, weeniest bit of really crisp toast’, adding, ‘Because what she wants is smaller and less costly than what has been set before her, she never recognises as gluttony her determination to get what she wants, however troublesome it is to others.’ Obsessive dieting can be just as much a sign of gluttony as overeating.  

Gluttony then is an inordinate obsession with food, drink or plain consumption. It is allowing food to take up a distorted place in our lives, just as lust is allowing sex to become an unhealthy obsession. 

We have a fascination with food. A TV advert lingers slowly over a picture of a chocolate sponge, soaked in brandy, with rich cream being poured over it, all with a soft, seductive voiceover describing the scene – a culinary striptease. The cookbook section of my local bookshop is far larger than the religious section – who had ever heard of celebrity chefs thirty years ago? Now they are everywhere. The politics of food is also an area of tricky choices and legislation. Fine food and wine costs both time and money, and poorer families tend to eat less healthily. Should they be banned from doing so for their own good? Should we replace chips and hamburgers with healthy salads in school canteens despite what the kids and their parents want? Where does the health of the nation override personal freedom to eat what you feel like?  

There is one story in the Bible that sheds some light on gluttony. It is the one where Jesus was tempted by the devil. During the temptations, Jesus deliberately goes without food. One of the enticements of the devil is to persuade Jesus to feed himself by the magic trick of turning the desert stones around him into bread. After all, that should be no problem to the Son of God, and it would of course demonstrate his true identity by a display of miraculous power. Jesus replies with some words from the Old Testament:  

“It is written: ‘Man does not live on bread alone, but on every word that comes from the mouth of God.’”  

The point is that when food becomes a god it becomes dangerous. Food, like sex, has the ability to skew things, and so it must be kept in its proper place, and the evidence of that is all around. The irony of our western problem with obesity is that it occurs at a time when still half the world, three billion people can't afford a healthy diet. one in ten people worldwide go to bed hungry at night and nearly half the deaths of children across the world under 5 are related to undernutrition. In 2006, for the first time, the number of overweight people in the world (1 billion) overtook the number of malnourished people (800 million). First world gluttony is anomalous when related to third world poverty and hunger.
