Gluttony’s unconscious self-image of emptiness

In the seventh of a series on the Seven Deadly Sins, Graham Tomlin digests gluttony’s distorting obsession with food.

Graham is the Director of the Centre for Cultural Witness and a former Bishop of Kensington.

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.   

Obsessive dieting can be just as much a sign of gluttony as overeating. 

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. 

Gluttony is trying to fill a spiritual vacuum with a physical remedy. It is like taking penicillin for a broken heart. 

But overeating is not the only way of abusing food. Obsessing about quantities is also a sign of bad soul health. Bulimia and Anorexia are not as common as obesity, but they still blight the lives of around 10 per cent of college-age girls in the USA, and in the UK, more young people than ever before are receiving treatment for eating disorders. Suffering from Anorexia, Bulimia or a Compulsive Eating Disorder are not sins, but they are an indicator of something that has gone wrong. Food is not a neutral thing, and in a complex way, our attitudes to food are all bound up with our spiritual and emotional health.  

This begins to point us to the reasons why Christianity has found gluttony a sin. Why do people overeat, or starve themselves? Many studies suggest that these disorders often emerge from a sense of lack of worth. We all know the pattern of comfort eating. When you feel a bit low, a slice of chocolate cake or apple pie can make you feel a whole lot better. Ten pints of lager or a couple of stiff whiskies can help you forget why you felt bad in the first place. Similarly, anorexia or bulimia often emerge out of patterns of unhappiness or self-dislike. The Eating Disorder Association says that such patterns of self-abuse are usually caused by such things as “low self-esteem, family relationships, problems with friends, the death of someone special, problems at work, college or at university, lack of confidence, sexual or emotional abuse. Many people talk about simply feeling ‘too fat’ or ‘not good enough’”. 

Now these of course are extreme cases. Yet they point to the ease with which we use food and drink to fill something missing in our lives, to comfort us when we feel lonely, to satisfy us when we are not just physically, but also spiritually hungry.  

The Ethicist Peter Kreeft puts it well:  

“The motivation for gluttony is the unconscious self-image of emptiness: I must fill myself because I am empty, ghostlike, worthless.”  

Gluttony is trying to fill a spiritual vacuum with a physical remedy. It is like taking penicillin for a broken heart – there’s nothing wrong with penicillin, but it doesn’t do much good for a restless soul, and too much of it can lead to all kinds of problems.  

Gluttony strikes when the connection between food and its proper purpose is broken. Food is given to sustain the body, to enrich our communal life and to give pleasure to the taste. It is not there to comfort the isolated and lonely, to bolster a fragile self-image or to substitute for mediation or prayer. If you begin to recognise that you are regularly eating alone for spurious reasons, for reasons that seem different from the purpose of food itself, that may be when you need to watch out for the place of food in your life, or to get some help.  

Gluttony rears its head when we begin to get food out of proportion. They key issue here is control. The overeater loses control over how much she eats. She is unable to stop herself taking the extra large Coke, the extra cream on the pudding, to finish off the packet of biscuits rather than stop at one. She believes the lie that it is impossible for her to control his eating. For the anorexic or bulimic, the issue is the other way round. For many sufferers from such diseases, or those who might have a tendency in that direction, the problem is too tight a control over what they eat, and their very identity becomes bound up with their illness. So here, the remedy is to learn to give up control, to re-form their identity around something other than eating habits, so that food can take its normal place as something to be enjoyed.  

If the abuse of food often comes from a deep sense of dis-ease, a loss of self-worth, then the Christian answer to finding a true sense of being worth something can come only from the source of life himself, the one described in the Bible as the ‘bread of life’ - the one who gives food for the soul. Speaking of the emptiness that gluttony tries to fill with food, Peter Kreeft goes on to give the Christian answer to that emptiness:  

“Only a knowledge of God’s love for me can fill that emptiness, make me a solid self, give me ultimate worth.”  

When our desperate search for love is met by the deepest and most satisfying love of all, the love of a God who is Love, these deepest hurts can begin to be healed.

Not just red in tooth and claw: biology's big debates

In the second of a series, biologist and priest, Andrew Davison, examines why it’s important to keep up with biology’s big debates.

Andrew works at the intersection of theology, science and philosophy. He is Canon and Regius Professor of Divinity at Christ Church, Oxford.

There’s hardly been a livelier time for evolutionary science than today; indeed, passions can run high. It’s not that Darwin’s vision of evolution is fundamentally in doubt: species adapt by natural selection, there’s variation between individuals, and those better adapted for their environment survive more often, passing on their genes to their children. In that, the theory of evolution stands, but many other parts of the evolutionary picture from the second half of the twentieth century are coming under criticism. That includes the following maxims:  

‘the only significant form of inheritance involves genetic code’, 

‘nothing that happens to an organism during its lifetime is passed on to its progeny’,  

‘we agree what we mean by “species”’,  

‘genes pass down the branches of the tree of life, not between them’,  

and ‘evolution is fundamentally all about competition, not cooperation’. 

Among the excellent crop of writers on these themes, Eva Jablonka and Marion Lamb stand out for their elegant prose, and a gift for communicating complex ideas clearly. As they recognise, the standard mid-twentieth century model of evolution might be worth criticising, but it’s also landed all sorts of important basic points. (They list ten.) The shortfall of the earlier, dominant theory was in being too narrow, with each insight too quickly eclipsing others.  

Here are two examples. First, the classic twentieth century picture saw inheritance in terms of DNA and genes, passed on by ‘germline’ cells, such sperm and pollen. That’s all true, but it shouldn’t restrict our wider view of inheritance to that. Today, writers such as Jablonka and Lamb stress that organisms inherit from their parents (or parent) in all sorts of ways.  

A second plank of the twentieth century picture is that evolution involves descent from a common ancestor. Again, that says something vital, even central, accepted by evolutionist old and new. The twentieth century position, however, added a restriction: that’s all that’s important on this score. The newer perspective recognises that while genes are – of course – central, and passed on from parent to child, organisms also swap genes between themselves (between branches of the tree of life, not just along those branches), even between very different species. 

If we’re not careful, what’s written and taught (not least by theologians), even with the best will in the world, will be thirty or even fifty years out of date. 

There’s a lot of excitement around these sorts of claims (and, remember, Jablonka and Lamb make eight more), and that can get quite noisy. Defenders of the older, narrower picture typically say that the newer themes are simply fuss over minor points. Advocates of the newer perspective disagree, saying that the twentieth century picture risks missing some important features of biology, which are now coming into better focus. 

Why such debates matters 

Why might this ferment among biologists matter for a site like this one, and for theologians, and discussions of religious matters? Well, for one thing, as I pointed out in my previous article, nothing quite dissolves the supposed animosity between science and religion (which is, after all, a relatively recent invention) like theologians and religious people getting excited about biology. It’s also important that any humanities scholar, the theologian among them, who’s engaging with science should keep up to date. If we’re not careful, what’s written and taught (not least by theologians), even with the best will in the world, will be thirty or even fifty years out of date. 

But there’s more at stake. As we have seen, the twentieth century picture, for all it brought an admirable clarity to evolutionary thought, was reductionistic. We see that in Jablonka and Lamb’s exhortation to scientists: ‘yes, stress x, but don’t think that means you have to deny y.’ A religious vision tends to be an expansive one. It wants to recognise the reality and value of all sorts of things. Yes, there’s matter, atoms, molecules, and genes, but there’s also organisms, agents, cultures, groups, economies, hopes, loves. They’re all real. We can’t reduce one to the other: not organisms to genes, or agents to economies. A turn from reduction is welcome. 

More than that, almost everything in the emerging twenty-first century view of evolution is fascinating from a theological perspective.  

Take convergence, for instance. It turns out that evolution isn’t just driven by randomness, or by the demands of the surroundings. Also important are various features of physics, or mathematics – the contours of reality – that throw up elegant solutions to evolutionary problems, which are adopted by evolution time and again. Wherever you need to sturdy and space-efficient packing of cells (as in a honey comb, or a a wasp’s nest), the hexagon is ready and waiting.  Wherever there’s water or air to navigate, the laws of fluid dynamics are bound to throw up wings, and bodies shaped like fish, dolphins, and penguins (which are all quite similar in shape).  

How do we know this? Because evolution has converged on wings and that body shape independently, many times, as also on eyes, and everything else that Simon Conway Morris lists in the nine closely printed columns of convergences in the index to his book Life’s Solution. Evolution certainly involves randomness and need, but alongside them is something more like Plato’s forms: timeless realities, there to be discovered and put to work. Among the more theological of these eternal verities, covered in Conway Morris’s book, are perception, intelligence, community, communication, cooperation, altruism, farming, or construction 

 Exceeding a zero-sum game 

Then there’s cooperation. Ever since Darwin’s Origin was published, and, even more, ever since Tennyson wrote about nature ‘red in tooth and claw’, theologians have been embarrassed about the place of cooperation in their vision of the world. Now, however, it turns out, competition isn’t the only force at work in biology or evolution after all. One of the features of reality that evolution discovers and puts to work again and again is cooperation, and ways to exceed a ‘zero-sum’ game. We see that in cooperation within a species, but also in cooperation between species, which is ubiquitous in nature: called mutualism, it’s found everywhere. As a rule, once two species stick around in proximity for the long run, down many generations, their relationship will turn to mutual benefit.  

Ethicists are often wary of the suggestion that we can look at the way things are, and read a moral code there (getting an ‘ought’ from an ‘is’), but it’s an unusual person whose vision of right and wrong isn’t shaped, to some degree, by a sense of what the world is like. Well, it turns out that nature bears witness to the enduring worth of cooperation, and not only to competition.   

In the first of these articles on biology, I pointed out the significance of ethics in thinking about biology, and about evolution in particular. For better or worse, and often for worse, thinking about evolution has been an ethical, social, political story. The evolutionary has been put to work for immoral, ends. It turns out to be wrong twice over to suppose evolution commends only competition. It’s wrong, first of all, because we are rational creatures, who can aspire to an understanding of good and evil that transcends the realm of nature. But also, as we now see, it’s wrong even to suppose the nature is only red in tooth and claw. There’s competition, but there’s also a lot of cooperation.
