Living sustainably doesn’t have to be a burden, here’s the case for action

The fundamental tenets of Christianity show why Christians are called to love not just one another but all created things.

1. God is love.

2. God created everything.

Therefore, God loves everything he created.

3. God appointed humanity as the guardians of creation.

Therefore, a fundamental part of our identity and calling as human beings is to protect and sustain all that God created.

This lies at the basis of everything Christians believe and do. But a case can be made that is more basic still because it appeals, not to anything distinctively Christian, but to natural human wisdom. The climate crisis is not a Christian crisis. It’s a crisis for everyone who cares about their future and that of our planet. The climate crisis may be something unprecedented in the history of humanity, but the principles that are needed to resolve it are not new at all. Sustainability is not a new or particularly abstruse idea. It is something everyone understands as basic common sense. If I cut down trees faster than they can grow, I won’t be able to do that forever. One day I will cut down the last tree and then there won’t be any more trees, ever again. If I catch fish faster than they can reproduce, then one day I will catch the last fish and then won’t be able to catch any more ever again.

But it’s not only about foresters and fishermen. Since the dawn of humanity, we have been living sustainably – wisely preserving resources and using only what we can replace, so that we and our descendants can continue to live. This applies to everyone regardless of their profession. All of us, if we spend more money than we earn, are living in a way that cannot last for long. If we use resources at a faster rate than we can replenish them, we will run into trouble at some point in the future. Every person possessed of reason and common sense knows this intuitively without having to be taught it. Only someone seriously deluded, foolish, or with some kind of mental health problem fails to understand the need for sustainability in order to have any kind of future at all, let alone a pleasant future.

The call to live sustainably can lead us to feel burdened by a permanent sense of guilt, a feeling that we ought to be doing more than we are...

We are burning fossil fuels at hundreds of times the rate they can be produced. We are producing plastics that cannot be recycled, meaning we have to dump them in landfills that are growing all the time. We are pouring carbon dioxide into the air faster than anyone can take it out. All of these things mean that there is a time limit on the kind of lifestyles we are all leading now. If we carry on in this way, then one day we will cross a line from which there is no returning. As Mark Scarlata has pointed out, the solution cannot be technological. Even if we find a way to balance carbon outputs with inputs, we are only kicking the can further down the road. Our inability to live within our means will simply resurface somewhere else later on. The problem is spiritual, not technical.

Everyone understands this at some level even if it’s the kind of truth from which we prefer to avert our eyes. The harder problem is to understand why this basic common sense isn’t proving effective. Why are we living collectively in a way that only a foolish or insane person would live, when most of us taken by ourselves are neither foolish or insane?

The problem, at least in part, is that we are all entangled in systems that make it very hard for us to live sustainably. If I am an ordinary Brit living in an ordinary town or city, and I need to buy toothbrushes or nappies or cucumbers or strawberries, I go to the local supermarket: and the only options available are made of plastic or wrapped in plastic that will not decompose for 500 years, and often brought here from the other side of the world using huge amounts of carbon emissions. Most of us are busy people with limited financial resources. We don’t have the time to find sustainable alternatives and often they are too expensive even if we can find them. The societal structures that we live in limit the choices we have. The call to live sustainably can lead us to feel burdened by a permanent sense of guilt, a feeling that we ought to be doing more than we are, but also an inability to see how we could be doing more given all the pressures, needs and constraints on our time and money.

Christians do not naively believe that God will sweep in and fix everything if we just wait. That would be to deny our responsibility, and it is not what hope means.

We are all culprits in part, since we all contribute to non-sustainable living. But we are also partly victims of forces beyond our control, large cultural forces that shape and determine our actions more than we can imagine. We have very little power over those structural forces and currently things do not look good. Common sense principles aren’t working. The climate crisis is only getting worse. So, what do we do?

It is at this point that Christianity has something special to offer to the problem.

First, Christians are never called to be defeatist or to throw in the towel. This is because we are called to an enormous hope, a hope that surpasses understanding, a hope that the world cannot understand because it stands over against all the odds and all the possibilities. This hope is rooted in the conviction that our God is God Almighty, that he has not abandoned his creation, and that he has power to save. He is a saviour. He is the God of our salvation. This is the God we believe in. The climate crisis may look bleak right now, but Christians need never despair or become indifferent. If we do our small part, we can trust that God is in control of what is out of our control.

Secondly, Christians believe that every human being is a free agent with the capacity to choose how he or she will act. Our freedom may be limited by the societal structures that shape and constrain our choices, but it is not destroyed. We can still make choices within those limits to buy and live more sustainably – anything from choosing a holiday destination within driving distance, to giving up beef (by far the worst food for carbon emissions). There is something all of us can do.

Thirdly, Christians believe in a God who transforms hearts and lives, winning them to the power of the gospel and to a new way of living that is free of the shackles that this world – the structures of society – puts on us. This transformation is slow – slower than we would like it to be sometimes. We feel the shackles still gripping us at times. We are not expected to change everything all at once, to become holy overnight. Nevertheless, God gives us the power to change our lives, and to become part of the solution rather than part of the problem. The way towards sustainable living is not to try to change everything at once, but to ask: what one thing can I change in my daily lifestyle that would make it more sustainable? And then once we’ve mastered that and integrated it so we no longer even think about it and it’s just a default, then we can ask: what’s the next thing I can do? All of a sudden what looks like an unimaginable height of transformation, when it is broken down, becomes a series of manageable steps.

Even if we do everything in our power, we cannot by ourselves avert a possible catastrophe. We are small players in a big game. Christians do not naively believe that God will sweep in and fix everything if we just wait. That would be to deny our responsibility, and it is not what hope means. Hope means the opposite: that we continue to fight to avert climate disaster even when it seems hopeless. Christians are called to be part of the solution rather than part of the problem. We are called to live in such a way that, if catastrophe comes, it won’t be because of us – to live in hope that our actions are meaningful and worthwhile and that we are in the hands of a God who is far more powerful than the most powerful forces in this world.

Why does the Pope matter today?

The personal, vivid link to the origins of the movement that changed the world.

Graham Tomlin

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

The author meeting the late Pope, 2024.

There is something about the way popes are elected that captures the imagination. Whoever dreamt up the idea of black smoke for ‘no decision’, and white smoke for ‘habemus papam’ – ‘we have a new pope’ - was a genius at marketing. So much better than a press release or a tweet from the Vatican X account.

The conclave was brought to our imagination so vividly by the recent film with Ralph Fiennes. We love the idea of secret debates, intrigue, people locked away from the world until they come to a decision with arcane ancient rituals and an uncertain outcome. Was there ever a film whose release was better timed?

There are also the sheer numbers involved. There are approximately 1.4 billion Catholics in the world today – roughly the same as the population of India and China, the world most populous nations. Yet the identity of the new pope is of matters to the rest of us too. The leader of China of India is of interest especially to people living in China or India, but maybe less so for those of us who don’t. The new pope is the head of churches round the corner from where you live, or of people with whom you work, or, if you are Catholic yourself, your own spiritual leader. This appointment matters.

Yet it’s not just the optics, the drama, the numbers. And it’s not just for Catholics either. I am an Anglican, and since the Reformation of the sixteenth century, we have had in our own 39 Articles the statement: “The Bishop of Rome hath no jurisdiction in this Realm of England.” That might seem to settle the matter that it’s of no interest to English Protestants. But that would be wrong.

I met Pope Francis once. It was at a gathering of Anglican Archbishops in Rome last year. We all were led through magnificent Vatican corridors into an imposing state room, adorned with fantastic frescoes, where the white-robed Holy Father was brought in on his wheelchair to deliver a brief 20-minute homily to us all.

It was a good talk, thoughtful, well-constructed, but in many ways unremarkable. It didn’t say anything much that I hadn’t heard from other sources. Yet somehow this was different. His words carried a weight, a gravity that went beyond the content of the lecture itself. It was as if, when he entered that room, he carried with him two thousand years of church history.

The line of Bishops of Rome goes back to St Peter, the gruff, unschooled fisherman who Jesus called from his mundane life to become an apostle, and who then on, was so captured by the person of Jesus that he gave his life in the cause. I left that room conscious of the weight of the office of the papacy, even if I don’t recognise him as my direct spiritual father.

Listening to this successor of St Peter felt like you were listening to one of the friends of Jesus – and this was not just the personal quality of the man himself, but something about the office he occupied. It was a personal, vivid link to the origins of the Christian movement, the first stirrings of the revolution.

The papacy is one of those unique things in modern life - an umbilical link to the past.

Of course, there have been some pretty terrible occupants of the papal see, whose personal lives showed scant evidence of any knowledge of, or relationship with Jesus. The sixteenth century Roderigo Borgia (Pope Alexander VI) comes to mind, who despite the rule on clerical celibacy, had several children from various mistresses, won the Papacy by bribing cardinals, and made his favourite son bishop of several lucrative sees at the age of eighteen, and a cardinal at nineteen. So, there is nothing automatic about this – which is why the Protestant Reformers denied the idea of any blanket automatic papal authority.

Yet when a person of evident holiness is combined with this notion of the weight of the office, the papacy becomes a gift to all of us, linking us back to the earliest followers of Jesus – even to Jesus himself.

The papacy is one of those unique things in modern life - an umbilical link to the past. Monarchies do something similar – linking us to the past through the long line of kings and queens of England, Denmark, Spain or wherever, yet more often than not, the events they lead us back to, the process by which those families took power, reveal murky politics, bribery and bloody battles.

This is a line in history that links us to the event that, if Tom Holland’s Dominion is to be believed, has had more impact in shaping western culture than any other – the remarkable life, death and resurrection of Jesus – a radical life full of love, self-giving and transformative power – for both individuals and whole civilisations. And for that, whether we are Catholic, Protestant, Orthodox, or even, perhaps, unbeliever, we might raise a prayer - or a glass - of thanksgiving.
