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.

The Wild God we can't coerce

Weird and increasingly encountered beyond the wilderness.

Christianity is a wild thing.

I say this, even while only half-understanding what I’m saying. It’s something that I’m learning. Or perhaps it’s more appropriate to say that it’s something that I’m unlearning. Because, admittedly, I’m far more familiar with a somewhat domesticated view of my own faith tradition. The kind that allows me to fashion fences out of my expectations; to put parameters around God’s presence and boundaries upon his behaviour. Both of which are a farce, of course - but a comforting farce, none the less.

You see, there is nothing ‘comfortable’ about a God who cannot be wholly predicted or comprehended, let alone controlled or contained. A wild God is always going to be a challenge to a culture that has enthroned comfort. We’re too easily spooked and too unused to the sensation of being cosmically baffled.

But, affronting as it may be, I am trying my best to sit in the knowledge that the God I believe in is a wild God. And I’m finding this wildness increasingly hard to ignore. Perhaps it’s all the Rowan Williams I’ve been reading, or my newfound interest in the Romantics (as in, the eighteenth and nineteenth century poets, not the 1970’s American rock band). Or maybe it has more to do with Nick Cave and the Bad Seeds’ new album, which I have been listening to relentlessly over the last week.

In this musical offering, Nick Cave introduces us to his ‘Wild God’, who I think is my God too. It’s just that ‘wild’ has never been the first adjective I reach for when describing him.

Until now, I suppose.

Let me clarify what I mean by wild, because what I’m not saying is that God is inherently chaotic, unruly, reckless or irrational. Wild Gods, as we know them from the myths and legends, act on tempestuous whims, and are more than a little havoc prone. They are perilous, largely because one can never truly know where they stand with them. That couldn’t be further from what I mean. The entire Old Testament - as complex, nuanced and masterful as it is - can be understood as a collection of ways in which the God at its centre is saying – this is who I am, this is what I desire, this is what I’m going to do, this is where you stand with me. If you were to read the Bible, it would become pretty clear pretty quickly: God is insistent that those who seek to know him will never have to second guess him. God’s wildness does not mean that we cannot know the essence of who he is or how he feels towards us. I like to think that we can endeavour to know him accurately, but never exhaustively.

Rather, what I’m trying to get my head and heart around is the knowledge that God, and therefore Christianity, cannot be wholly domesticated. Despite my best efforts, it cannot be made into an entirely comfortable and cozy thing. To make it so, one would have to dilute it, shrink it, bleed any truth out of it. In his poem - Sometimes a Wild God -Tom Hirons writes,

Oh, limitless space.
Oh, eternal mystery.
Oh, endless cycles of death and birth.
Oh, miracle of life.
Oh, the wondrous dance of it all’.

There’s an innate weirdness to the Christian worldview, a pure wildness at the heart of it. It’s brimming with mystery and mysticism. As Hirons hints, it’s bigger and more consequential than our comfort-zones would like it to be. And, what’s more, much of it is communicated through the natural world. Biblical narratives and poetry are endlessly pointing us toward the places and spaces that are outside human cultivation – the stars, the mountains, the oceans – the things that pre-date and will outlive us.

Christianity is wild in that there’s an alluring organic-ness about it. Its truth sits beyond human manipulation and coercion.

For millennia, whole lives have been given over to this truly wild and, I believe, wildly true story. Can I give you just two recent examples? Two people who have (utterly unexpectedly) adventured their way into this wild and wonderful way of seeing the world? Two people I’ve had the joy of learning from over the past year?

First up is Paul Kingsnorth.

Paul is an award-winning poet and a best-selling author of both fiction (including the Buckmaster Trilogy: Wake, Beast and Alexandria) and non-fiction (including Real England, Confessions of a Recovering Environmentalist and his ongoing Sub-Stack series: Abbey of Misrule). He is, and always has been, an advocate for treating the natural world as if it were far more than a machine to be used or a resource to be obtained. Such behaviour is, according to Paul, nothing short of sacrilegious. As well as an enchantment with what he can see and sense in the natural world, he also has a long-standing fascination with all things mystical.

Buddhism, Witchcraft – you name it, he’s tried it.

He told Justin Brierley and I the story of how he his adventures have led him to arrive at the wildest possible destination: Christianity.  

And then there’s the renowned mythologist, Dr Martin Shaw, who decided to do a 101-day wild vigil in Dartmoor. Despite not being a Christian, on the very last night, he prayed. While praying, he looked up and saw something utterly unexplainable, something ‘properly Old Testament’. And that was it – after a night of dancing, several other ‘odd’ experiences, and eighteen months of deep pondering – he was able to say, ‘I went into the forest expected to be wedded to the wild and I came out wedded to Christ’.

Thinking about it, it’s probably no accident that ‘Christianity’ began on the margins, and from there, worked its way into the cities. There was a time where the prediction of Jesus’ arrival was being yelled out into the countryside, so loudly that people were emptying the surrounding towns to come and hear more. A time when rumours of redemption were being whispered in the rural hills. A time when its chief messenger was an inexplicably weird man named John the Baptist; who shunned his prestigious priestly heritage to live in the wilds, to dress in camel skins, to eat honey and insects and insist upon the imminent coming of the long-awaited Messiah. This Messiah, by the way, who would be born where animals are kept, sleep on mountains, retreat into deserts, walk on water, speak to storms, and break people (including himself) out of stone graves.

You see what I mean, Christianity is a wild story to believe and live in accordance with.

It’s the story that drove the ‘Desert Mothers and Fathers’ of the Third Century AD to reject civilisation and all its comforts, in order to seek God in the silence and solitude of the desert. It’s the story that is still inspiring people to live in caves on Mount Athos, secluded islands just off the coast of Wales and forests in the heart of Ireland. An uncontainable message has, since its inception, been lived out in uncontainable places.

Honestly, you want weird? Christianity can darn-well give you weird.

Don’t be fooled by over-familiarity or be swayed by that pesky left-side of your brain, the part that wants to convince you that you know all that there is to know. Christianity is a story that I, myself, had forgotten was quite this wild.
