Intermittent fasting? Try the 5th century playbook

Lent is upon us – those 40 days of voluntary masochism that we moderns have mercifully put behind us. Or have we?

Fasting, at least in the health world, is no longer a derogatory term but one in vogue. Particularly the merits of the restricted diet, in which you limit the amount of time you eat either to a day (e.g. to an eight-hour window) or a week (e.g. skip eating on two different days). The latter approach, maybe surprisingly, follows in the footsteps of our religious forebears, who fasted every Wednesday and Friday. Could it be that they’d figured out a practice we are just discovering? And what else were they trying to achieve?

To a medieval peasant in Britain, Lent ratcheted up the twice-weekly fast. It was 40 days of a vegan diet, that often increased in intensity as the body adjusted (though the pregnant, young, sick and old were exempt). Lent also issued in much cultural creativity. Who knew that Cathedral at Rouen was a Lenten by-product, as those desperate for butter could get a dispensation by contributing financially to the Butter Towers (as they became known)? And Britons may have Lent to thank for both black peas, a Lancastrian delicacy, and fish & chips, as cooks were challenged to keep Lenten menus interesting.

Despite our caricatures of Lent as a dour and draconian time, it was essential to the enjoyment of medieval life. The purpose of Lent was not the denial but the renewal of pleasure. Maybe it’s precisely that aspect that has echoed through the centuries, manifesting now in our punishing diets, Tough Mudder races, and endurance stunts. Isn’t that a bit part of why we (well, some of us) do them?

'One of the principal rhythms of medieval life was this move from feasting to fasting to feasting again.'

Our modern fascination with fasting can also receive wisdom from Lent, which is that fasting for its own sake will always lead to something unhealthy. It must be for the purpose of something greater. Our forebears worried that physical practices could become idolatry, when wrenched out of their context of repentance. As G. K. Chesterton remarked,

'Physical nature must not be made the direct object of obedience; it must be enjoyed, not worshipped.'

The Old Testament prophets were particularly grumpy about this, insisting that fasting would do no good if it did not also help you love your neighbour more. Or as the early third-century Christians who fled from Roman excess into the deserts remarked,

'If you fast regularly, do not be inflated with pride; if you think highly of yourself because of it, then you had better eat meat.'

Fasting on its own will not make us better people, though we might shed a few pounds. Fasting is to restore the pleasure not only to eating, but also to the soul in need of God. Interesting that one of the primary biblical metaphors for a lively spiritual life is that of feasting and eating. Fasting resets the soul with repentance. It is praying with our body. It is not a negation but a purgation of desire – not denying our desires but resetting them. C.S. Lewis wondered whether our desires are not too strong, but too weak.

'We are half-hearted creatures, fooling about with drink and sex and ambition when infinite joy is offered to us, like an ignorant child who wants to go on making mud pies in a slum because he cannot imagine what is meant by the offer of a holiday at the sea. We are far too easily pleased.'

So if you’ve considered intermittent fasting, or even if not but you feel you might need a more balanced perspective on pleasure, consider the Lenten playbook. Feast and fast cyclically. Do it for a greater purpose than just losing weight. Let it change and reset your true desires. And maybe, just maybe, you might discover God waiting for you at the root of all your desires.

Those unexpected angel stories

Shedding a strange light on a disenchanted world.

Unlike Robbie Williams, who sings about them, sometimes I preach about angels. When I do something always happens – people start telling me their own angel stories.

There was the one a soldier friend told me. During an army climbing expedition to Mount Kenya, one of his team had fallen to his death from a sheer rock face. Caught up in the drama of the moment, my friend found himself stuck on a ledge, unable to move up or down, paralyzed by fear and frustration. Suddenly, in an inaccessible part of the world, where they had seen no-one for days, on a mountain where they were the only registered group present, a climber appeared out of nowhere, moved onto the ledge where he was standing, tied a rope into his harness, lowered him down the rockface to safety before disappearing up the face never to be seen again.

Or the story of a pastor who got into trouble in an airport. A stranger walked by and asked if he could help, and remarkably fixed a seemingly intractable problem. The grateful passenger took a selfie of himself and the stranger, but when he looked at the phone later on, there was a picture of himself, grinning into the camera, with his arms around… nothing.

Why do so many stubbornly believe in angelic beings, when a materialist view of the world laughs scornfully at the idea as a bit of pre-modern superstition?

These are not just modern stories. In the second century, a young man called Justin from Asia Minor was working his way through the various schools of Greek philosophy. One day, he was walking along the beach at Ephesus, wondering, as young people have always done, about the meaning of life in general and his own life in particular, when a mysterious old man came alongside and joined him in conversation. As they walked together, the old man spoke about the philosophers and how none of them were quite able to answer the deepest mysteries of life. He advised Justin to read the Old Testament prophets, before disappearing into the distance. Justin did so, became a Christian and went on to become one of the greatest early theologians of the Church and one of its early martyrs for the faith – hence the name he is remembered by today - Justin Martyr.

Was it an angel? Or a real, yet mysterious old man? Are angels real? And if so, what is the point of them? Surveys tell us that 30 per cent of British people believe in angels. In the USA that figure rises to 70 per cent. Why do so many stubbornly believe in angelic beings, when a materialist view of the world laughs scornfully at the idea as a bit of pre-modern superstition? After all, the cynic might say all these stories can be explained - these were just ordinary people who turned up unexpectedly.

The encounter opened the eyes of the person in the story to another realm, a world unseen yet just as real as the seen.

The word angelos in Greek simply means messenger – and it can mean either a human or an angelic one. In the Bible, angels don’t usually appear with glowing white clothing and wings sprouting from their shoulder blades. When they come to people with a message, they often appear in the guise of ordinary people. In fact, it’s often hard to tell whether you have been visited by an angel or just another human.

The point, therefore, is not so much about the angels, but about the message that they bring. They tend to turn up when there is something particularly important to announce, something like the birth of Jesus, when an angel appears to the young Mary to tell her the news that she will give birth to the Son of God, her, and then quite a few of them turn up to sing to the shepherds, an indication that something big was happening.

In each of the stories above, the encounter opened the eyes of the person in the story to another realm, a world unseen yet just as real as the seen. An inexplicable encounter with what just might have been an angel has the capacity to open our eyes to the fact that the world is bigger than we often assume – that as Hamlet says to his dull, practically minded friend: “There are more things in heaven and earth, Horatio, than are dreamt of in your philosophy.”

The Nicene Creed, the classic summary of Christian faith, speaks of God as the ‘Creator of all things seen and unseen’. We are all used to what we can see, yet some of us only have space in our world for things that can be seen, touched or measured. Yet there are surely those unseen realities – things we cannot see or measure, like love, compassion, holiness, miracles, God and - yes – angels.

A random sermon on angels elicits hushed stories that people feel almost embarrassed to speak. Such mysterious experiences are far more common than we realise, as Dan Kim points out elsewhere on this site. Yet these experiences are not an end in themselves but are perhaps a way of God getting our attention when we refuse to listen to more ordinary approaches. These experiences open our eyes to a dimension of reality that is as real, if not as visible as the one we deal with every day – and become a gateway to a journey of discovery of an unseen world alongside the seen, that sheds a strange but welcoming new light onto a disenchanted world.
