In the blink of an eye

During the 24 hours of the earth's history, the 77 seconds of "humanity" include only 4 seconds of anatomically modern homo sapiens sapiens, 1 second of behaviourally modern homo sapiens, 0.23 seconds of agriculture and less than 0.04 seconds since Christ.

And in the last 0.001 seconds we have deforested half the world's tropical forests, dammed or diverted more than 80% of the world's major rivers, sent tens or hundreds of thousands of species extinct, killed more than one third of all wild vertebrates, altered the energy balance of the planet (melting more than 75% of summer Arctic sea ice), shifted the chemistry of the oceans (30% more acidic), removed roughly 90% of marine apex predators, dumped tens of millions of tonnes of plastic into the oceans, degraded more than 50% of coral reefs, introduced thousands of novel chemical compounds, disrupted the nitrogen cycle and caused dozens of other dramatic impacts.

Graphs can be terrifying: Getting a grip on CO2


H/T Gareth.
This soundless little presentation from NOAA's Carbon Tracker shows atmospheric carbon dioxide (CO2) concentrations over time. The first half of the video shows on the left hand side the yearly rise and fall of CO2 concentrations around the world since 1979. The various dots along the line each represent a different location around the globe, arranged by latitude, with the blue dot on the far left being the south pole and the dots at far right representing measurements in the Arctic. The dots rise and fall in a regular pattern as time passes. This is because trees "breathe in" CO2 during the northern spring/summer as leaves photosynthesise and then "breathe out" in autumn/winter as leaves decay, meaning that atmospheric concentrations rise and fall a little each year in a natural cycle. The annual variations are far more pronounced in the north hemisphere (the right end of the line that bounces up and down) since there is a much greater mass of land (and so trees) up here than in the southern hemisphere. So the concentration is never exactly the same at every point in the world or on every day of the year. And yet, along with the annual cycle there is something else happening. The overall movement is unmistakeable: up, up, up. If we look at the right hand side of the display, which shows the famous "Keeling curve" of average CO2 concentrations going back to 1958 when precise records first began to be kept (by Prof C. D. Keeling at Moana Loa in Hawaii), we can see that the annual rise and fall of the natural carbon cycle is superimposed on and ultimately dwarfed by a relentless upwards rise, which represents the human contribution to the situation. Each year we dig up literally billions of tonnes of carbon that had been safely stored for millions of years underground and burn it to power our lightbulbs and laptops, our concrete and cars, our fridges and flights.

Once the period 1979-2011 has been shown (up to about 1:40 in the video), we begin to zoom out, seeing further back in time. Initially, we are introduced to the earlier progress of the Keeling curve as it wobbles up and down back to 1958 (the green part of the cuve, spanning roughly 1:40-2:00 in the video). Then we suddenly begin zooming out much more quickly, and the green curve becomes a series of yellow dots spanning back to the time of Christ (2:00-2:20). Since the apostles were not measuring CO2, these measurements are "proxies", reconstructions of historical concentrations from a wide range of sources that have preserved a natural record of atmospheric concentrations. From 2:20-3:00, the blue curve represents a record of pre-historic CO2 concentrations going back 800,000 years (ka = thousand years; BCE = Before Common Era = BC) preserved in the ancient sheets of Greenland and Antarctica (Antarctica has the deepest ice and so the oldest records). The line here jumps up and down over many thousands of years as the world went into and out of glaciations (commonly, though incorrectly, known as "ice ages"). When CO2 concentrations were low (below 200 ppm), huge sheets of ice covered vast areas of land in the northern hemisphere. We have very good reasons for believing that CO2 concentrations played a crucial (though not exclusive) role in previous natural changes in climate.

The units used to measure CO2 concentrations are parts per million (ppm), that is, the the y-axis (vertical axis) represents the number for CO2 molecules for every million molecules of gas in the atmosphere, so 300 ppm means 0.03% of the atmosphere was CO2. These seem like tiny amounts and it is true that CO2 is a trace gas, but the effects of even small changes in some trace elements can be very large. If we were adding arsenic to a cup of coffee, then a mere 300 ppm would be sufficient to kill you. So don't be fooled by those who point to the "small" numbers involved. Changing the CO2 concentration from 280 ppm (as it was prior to the Industrial Revolution) to today's level of approximately 395 ppm represents the addition of more than a trillion tonnes of carbon dioxide.

So what does this all mean? This presentation very usefully shows the very large natural atmospheric changes in the earth's "recent" experience (recent by geological standards, since the earth itself is 4.5 billion years old). Notice that the difference between glaciers thousands of metres thick covering most of the UK and more temperate periods during which life can flourish on these isles was only about 100 parts per million.

Human agriculturally-based civilisation has only existed in the most recent 10,000 years (known as the "Holocene"), during which time CO2 concentrations (and so climate) have been fairly stable. Or had been.

So what we see (or is at least hinted at) in this video is (a) the ability of relatively "small" changes in a trace gas like CO2 to produce huge, world-changing effects on climate, (b) the relative stability (CO2 and climate-wise) of the period during which human civilisation has developed and (c) the dramatic and very sudden jump in CO2 concentrations during the last 150 years or so, accelerating rapidly over the last six decades. Compared to all previous changes, the rate of change we're seeing is off the charts. In comparison to even the steepest rises and falls during glaciations and de-glaciations, the last century or so has been basically a vertical rise, almost the equivalent of a de-glaciation in the blink of an eye. And we're already in uncharted waters, at concentrations not seen for at least 800,000 years (indeed other proxies that go back even further - albeit with lower levels of confidence - suggest that CO2 concentrations have not been this high for at least 20 million years). And if you look at the numbers on the y-axis, keep in mind that our current trajectory, in the absence of either global economic collapse or a massive energy and/or cultural revolution, will take us above 800, 900 or even 1,000 ppm during my daughter's expected lifetime. We ain't seen nothing yet.

And carbon, once removed from the stability and safety of underground storage, sticks around in the oceans, atmosphere and soils (the "active carbon cycle") for a very long time. We'll see elevated levels of carbon for hundreds and even thousands of years after we reduce human emissions to zero. It's important to keep clear in your mind the difference between emissions and concentrations. Emissions are like income going into your bank account, concentrations are like your account balance. So if we get to a concentration of, say, 700 ppm and decide to go on a crash diet of zero emissions, things won't return to "normal" for tens of thousands of years.
One recent study pointed out that CO2 released by pre-industrial deforestation continues to affect climate today, albeit on nothing like the scale of industrial activities.

Why is this a problem? Many serious and senior researchers believe that life as we know it is incompatible with CO2 concentrations above 450 ppm. In the long run, many think that anything over 350 ppm is too high since 450 ppm could well trigger the extinction of literally millions of species, perhaps a third of all those currently on the planet. Remember, we're currently at about 395 ppm and rising by more than 2 ppm each year.

Yet the insidious thing is that the effects of elevated CO2 concentrations are not immediately apparent. It can take decades for global temperatures to respond to shifts in atmospheric composition, centuries before the full effects are visible and millennia before sea levels will stabilise. So that means the crazy shifts we're already seeing are merely the result of where CO2 concentrations had reached back in about 1980 or so. Even with the best efforts, things are going to get worse for some time after we start taking this problem seriously. Thus any generation that chooses to forgo the seductive and wondrous benefits of fossil fuels will not immediately reap the rewards. We can always kick the can down the road for a few more years, but in doing so, we condemn our children (and their children and as many generation as we can imagine) to an increasingly hellish existence.

The difficulties of climate ethics: time

"[There is] a pronounced temporal dispersion of causes and effects. In the case of climate change, this is caused mainly by the long atmospheric lifetime of the main greenhouse gas, carbon dioxide, and by the fact that some of the basic physical systems influenced by the greenhouse effect (such as oceans) are subject to profound inertia, so that changes play out over centuries and even millennia. This is important because it suggests that whereas fossil fuel emissions have immediate and tangible benefits for present people, many of the most serious costs are likely to be substantially deferred to future generations."

- Stephen Gardiner, A Perfect Moral Storm:
The Ethical Tragedy of Climate Change (Oxford: OUP, 2011), 123.

This time lag is critical to grasping climate change (and, to a greater or lesser extent, many other ecological issues). Many people don't realise that the changes we are already experiencing (Arctic summer sea ice volume down by over 70%, shifts in timing of the seasons, more frequent heatwaves and intense precipitation events in some regions, poleward shift of ecosystems, thawing permafrost, rising sea levels and so on) are not the result of present greenhouse gas concentrations. We are merely reaping the start of the harvest of seeds sown decades ago. It will be decades more before the effects of today's levels begin to be visible, and centuries or even millennia before their full impact is known.

This temporal lag means that climate change occupies an intermediate position amongst future threats, too close to be safely ignored and too distant to avoid being perpetually trumped by the myopic focus on today's problem caused by the media and political cycle. Dangerous climate change is far more immediate than say, the heat death of the universe or even the death of our Sun (or the preceding gradual increase in solar radiation that will likely destroy all life on earth well before either of these), and yet not immediate enough to enter the horizon of political decision-making. That this is so can be seen in the frequent attempts to find proximate hooks of one disaster or another on which to hang the climate threat. Yet these are doomed to be of only ambiguous use since any single disaster always has multiple causes and climate change is about a shift in statistical distributions, rather than being the sole unambiguous "cause" of any given event. In this intermediate position, climate change is uncomfortably dangerous enough to be of real concern and yet always comfortably far enough away to ignore for one more day, lowering the chance that will anticipate with prudence such (slightly) distant futures.

Individually, we are frequently poor at responding to such delayed feedback. The causes of obesity, heart disease, lung disease, alcoholism and all kinds of other long term health problems are increasingly well-known and connected to various behaviours that are often deemed quite pleasant in the short term. Yet, despite the long term ill-effects frequently being catastrophic for our health, we continue to indulge.

And that is just for problems where the effects are on my own life a few decades in the future. But when we turn to issues where the worst effects are felt by others, separated from me by time, space, social distance and even species, then my ability to refrain from indulging in short-term pleasures becomes even more difficult.

And when we turn from individual responses to collective responses, yet another layer of complexity is added and the potential to pass the buck becomes even higher. And when these collective responses are required not only at communal, social and national levels, but also critically amongst all nations of any economic size, then the barriers can appear insurmountable. More on these issues in the days ahead as I begin this series looking at some of the reasons why climate change is a particularly knotty ethical issue.
As one illustration of the temporal lag, a new publication from NASA claims that, based on paleoclimate records, each degree Celsius of global temperature rise will, in the long run, be associated with something like a twenty metre sea level rise. For those who don't understand why it matters whether we rise two or three or four degrees, here is one example to clarify our thoughts. This is not saying that such rises will be immediate, but that we are committing our descendants to a very, very different world.

The end is nigh? Apocalyptic thought and our present distress

Apparently, the apocalypse has already come and gone. Did you miss it?

The relation of apocalyptic thought to our present and likely future distress is an interesting and complex question, not easily answered in a few sentences. I've recently been reading a book edited by Stefan Skrimshire titled Future Ethics: Climate Change and Apocalyptic Imagination, which I mentioned back here. As is usual in an edited collection of essays, quality and relevance vary considerably, but the theme is an important one. How do our images of "the end" shape our understanding (or misunderstanding, as the case may be) of climate change?

For some activists, the pace and scale of anthropogenic climate change on our current trajectory represents an existential threat to the present order of the biosphere, including the human order of a globalised industrial civilisation of almost seven billion and rising. The language of apocalyptic is borrowed in order to try to gain some traction with policy-makers and the public. It matters not whether this borrowing represents a reflexive reliance on a thread of thought with its roots in religious discourse or the deliberate appropriation of concepts and tropes that still inhabit our imagination and so which will resonate widely. The goal is to induce an emancipatory shock, a recognition of our situation as extreme, a justification for emergency measures that disrupt the usual flow of commercial, political and social life with a radical reordering.

Some Christians, noting the borrowing of apocalyptic language by activists, are inclined to ignore the whole thing as another human attempt to claim control of even how the world is going to end. Instead, affirming that the end is in God's hands alone, they argue that any claims of humanity bringing about the end by our own efforts (even inadvertently) must be treated with extreme suspicion.

Personally, while it is difficult to get a good grip on the magnitude of the threat represented by climate change without recourse to some very strong language, I think that it is best to remain agnostic about the relationship between our preset distress and threats and the divine promises relating to ultimate realities. It may be that there is some link, but there is no particular reason in my opinion to think so. Even if our actions lead to the downfall of our way of life and the utter transformation of our society into something so different that in hindsight it is appropriate to speak of industrial civilisation having experienced a self-induced collapse, this need not be the end of the world. To use a line that is growing increasingly common, the end of the world as we know it is not necessarily the end of the world.

And where this cuts the mustard for me is that sometimes apocalyptic thought can become a lazy way out of ethical deliberation. Apocalyptic becomes lazy where it is in the service of a fatalism that assumes our destiny is doomed by the greater power of nature (whether acting blindly, under its own authority as a personified (and angry) mother earth, or as the instrument of God's inexorable judgement) or which conversely rejects the possibility of social self-destruction in principle. In each case, the future is seen as closed and human actions as ultimately irrelevant, in which case, let us eat and drink for tomorrow we die. It can also be lazy where it is used to create panic and a desperate acceptance of whatever medicine is closest to hand. This is a kind of non-emancipatory shock that stuns the hearer into passive acceptance of the salvific social, economic and/or political solution that swiftly follows the apocalyptic account.

Denying knowledge of the relationship between our time and time's telos keeps open the space for neighbourly care. It does this not by rendering apocalyptic inscrutably distant ("since we can't know when the end will come, then let us ignore the coming of the end altogether"), but constantly relevant. In Christian apocalyptic, the hidden meaning of history is revealed to be the stage of divine action, not in competition with human action, but as the previously unknown judge and liberator of human action. Since the day of divine judgement approaches like a thief in the night, unbidden and unobserved, the wise servant knows that her actions are made more weighty, not less. Instead of paralysing fear or enervating schadenfreude, she is liberated to conduct her faithful service in reverent hope of divine vindication. By such acts, she is not heroically securing the future; saving the world (or the present world order) is not her motive or modus operandi. Instead, she trusts that because the hour of her vindication approaches, she has time to prepare, to reflect with prudence on her ability to be a blessing in the limited time she has received. Waiting patiently, she need not dread the outcome of history, but is free to love her neighbour as an instantiation of her wholehearted love for the master with what strength and wisdom she has received. It may be that the immediate future holds suffering, even vast suffering, but not yet the end of all things. In which case, her actions undertaken in hope are not in vain; they are secured by the promise of the resurrection, and thus they are freed from the impossible burden of having to deliver her own life or the continued existence of her society.

And so, there is a sense in which the apocalypse has indeed already come, in the sense that apocalypse means "revelation", an unveiling of what was hidden. After Christ's coming, Christian believers now see the world and its future in a new light. No longer do the dark shadows of anticipated difficulties leave us blindly stumbling along in denial, distraction, desperation or despair. Once relieved of the responsibility to pursue survival above all else, we see the future as a stage on which faithful words and deeds may witness to the redemption of history through the cross and resurrection, and to the coming renewal of all things.

Is catastrophe inevitable?

"[I]f we are to confront adequately the threat of (social or environmental) catastrophe, we need to break out of this "historical" notion of temporality: we have to introduce a new notion of time. Dupuy calls this the "time of a project", of a closed circuit between the past and the future: the future is causally produced by our acts in the past, while the way we act is determined by our anticipation of the future and our reaction to this anticipation:
The catastrophic event is inscribed into the future as destiny, for sure, but also as a contingent accident: it could not have taken place, even if, in futur antérieur [looking back from the future], it appears as necessary. ... if an outstanding event takes place, a catastrophe, for example, it could not not have taken place; nonetheless, insofar as it did not take place, it is not inevitable. It is thus the event's actualization - the fact that it takes place - which retroactively creates its necessity."
"If - accidentally - an event takes place, it creates the preceding chain which makes it appear inevitable: this, and not commonplaces on how underlying necessity expresses itself in and through the accidental play of appearances, is in nuce the Hegelian dialectic of contingency and necessity. In this sense, although we are determined by destiny, we are nonetheless free to choose our destiny. According to Dupuy, this is also how we should approach the ecological crisis: not to appraise "realistically" the possibilities of catastrophe, but to accept it as Destiny in the precise Hegelian sense - if the catastrophe happens, one can say that its occurrence was decided even before it took place. Destiny and free action (to block the "if") thus go hand in hand: at its most radical, freedom is the freedom to change one's Destiny.

"This, then, is how Dupuy proposes to confront the disaster: we should first perceive it as our fate, as unavoidable, and then, projecting ourselves into it, adopting its standpoint, we should retroactively insert into its past (the past of the future) counterfactual possibilities ("If we had done this and that, the calamity we are now experiencing would not have occurred!") upon which we then act today. We have to accept that, at the level of possibilities, our future is doomed, that the catastrophe will take place, that it is our destiny - and then, against the background of this acceptance, mobilize ourselves to perform the act which will change destiny itself and thereby insert a new possibility into the past. Paradoxically, the only way to prevent the disaster is to accept it as inevitable. For Badiou too, the time of the fidelity to an event is the futur antérieur: overtaking oneself vis-à-vis the future, one acts now as if the future one wants to bring about were already here.

"What this means is that one should fearlessly rehabilitate the idea of preventative action (the "pre-emptive strike"), much abused in the "war on terror": if we postpone our action until we have full knowledge of the catastrophe, we will have acquired that knowledge only when it is too late. That is to say, the certainty on which an act relies is not a matter of knowledge, but a matter of belief: a true act is never a strategic intervention in a transparent situation of which we have full knowledge; on the contrary, the true act fills in the gap in our knowledge."

- Slavoj Žižek, First as Tragedy, Then as Farce (London: Verso, 2009), 150-52.
Internal quote from Jean-Pierre Dupuy, Petite metaphysique des tsunami (Paris: Seuil, 2005), 19.

This somewhat dense passage is either nonsense, or very profound. It can be difficult to tell, and perhaps only hindsight will let us know for sure. But this is precisely Žižek's point: that we act (largely) in the dark, and certainly in the dark about whether future events are inevitable or not. A terminal diagnosis could prove to be wrong. But this doesn't mean we just write off such a diagnosis, no, we embrace it and feel the full weight of living under a death sentence, and then live as those who will be resurrected.

In praise of... short engagements

Prince William and Kate Middleton are to get married on Friday 29th April, within six months of announcing their engagement. For all else that will be written about this particular match, let me say that I'm a fan of short engagements (six months or less). Barring unusual circumstances (e.g. one partner being called off to war), short engagements have two great benefits. The first is relational, the second practical.

Relationally, engagement is an unstable time. Prior to engagement, only loose expectations form the relational bond. Both parties know that they can end the relationship for a variety of good reasons (there are, of course, also plenty of bad reasons, but the point is that good reasons exist). After marriage, lifelong promises bind the couple in a security that allows difficult issues to be faced with confidence that the other has publicly promised to keep holding and loving in whatever circumstances or difficulties arise. But during engagement, there exists the somewhat strange circumstance of a private promise that a public promise will be made. There exists during this period a rapidly closing door out of the relationship and this itself can bring added stress and uncertainty to the relationship. Limiting this stressful period to a definite (and relatively brief) period of time is healthy. Open-ended engagements seem either somewhat pointless or somewhat cruel. Once the decision to get married has been made, then all that is required is some time to prepare for the solemnity of the promises to be undertaken and to arrange the details of a wedding - which brings us to the second benefit of brief engagements.

Practically, the wedding preparation will expand to fill the time available. The longer that is given to this process, the more likely the celebration will grow into an all-consuming beast. Better to acknowledge that, while a day of great seriousness and great joy, a wedding is but another day that the Lord has made, and doesn't require great debts to be shouldered or unrealistic expectations (from whatever source) to be appeased. If present finances are insufficient to pay for the scale of expenses expected, then it is far better to humble one's expectations than delay the date. The point of the day is the making and celebrating of promises. All else is optional.

That said, I doubt the Prince and his family are accustomed to too much humbling of expectations. Yet humility befits even (perhaps especially) a future king.

How much do you love your employer?

"A survey has found that Australians are working more unpaid overtime than almost any other country in the world [...] according to the study, workers donate two billion hours of work worth $72 billion to employers each year. That's six per cent of GDP."

Phillip Lasker, "Australa World Leaders in Working Overtime", ABC Lateline Business.

"Did you know that in 2009 the majority of Australian employees did not take all their annual leave entitlements? Yet, only one in five of us are happy with the hours we work, with most of us expressing a desire to work less. This year's national Go Home On Time Day on November 24 is focusing on the notion of 'time poverty', something which what has been referred to as a 'modern malaise'. Our survey found that half of all Australians are suffering from time pressure, with overwork preventing us from keeping healthy and spending time with family. Half of all survey respondents wanted to work fewer hours than they had worked in the previous week. For those working overtime, four in five (81 per cent) wanted to work less."

Go home!

Ever find yourself strapped to your desk well after the end of your official hours? Does it happen often? When people ask you how you are, how often does your reply contain some variation on the answer "busy"?

Then stop reading blogs you might like to think about participating in Go Home On Time Day on 24th November in order to raise awareness of workaholism and overwork.

"Each year, Australians work more than 2 billion hours of unpaid overtime, worth an equivalent $72 billion.
For full-time workers, the average daily amount of unpaid work is 70 minutes which equates to six-and-a-half standard working weeks. Put another way, this is the equivalent of ‘donating’ more than your annual leave entitlement back to your employer.

"A consequence of overtime is ‘time poverty’ or not having enough time to do all the things you need or want to do. This can have negative consequences for your physical and mental health, your relationships with loved ones and your sense of what is important in life.

"One in four Australians report needing to go to the doctor but being ‘too busy’, while one in two don’t spend as much time as they would like with their family because of work. Work also prevents us from getting enough exercise, eating healthy meals, and other things that contribute to our wellbeing."

Spend less. Earn less. Work less.

“Sooner or later we spend what we earn. So if want to consume less we must earn less, and if we want to earn less we must work less. At least, we must perform less paid work. If that sounds shocking today, it is nothing more than a call to resume the great historical trend of declining working hours. Until the trend was disrupted in the 1980s, falling working hours were regarded as the surest sign of social progress. A return to the downward trend would mean a social choice to take less of the gain from productivity growth in money income and more in free time.”
- Clive Hamilton, Requiem for a Species: why we resist the truth about climate change (Sydney: Allen & Unwin, 2010), 86-87.
A while back, I suggested we make wealth history. This is more or less what I meant. The love of money is a root of all kinds of evil. And that is true both personally and as a society.

The goal is not simply less. The goal is more of the things that count: like time building and enjoying relationships of trust, time for reflection, time for rest, time to heal and dream and worship.

Of course, Hamilton has neglected two possibilities in this brief paragraph. The first is earning less through voluntary pay cuts. However, perhaps this can be regarded as agreeing to perform some of your paid work voluntarily. The second is generosity, in which money earned is not spent but rather given away to those in need. While this may increase the consumption levels of the recipient, this is a good thing if it means their basic needs are now met. However, if it simply means someone else consuming unnecessary luxuries, then while it may have other worthy beneficial outcomes, ecologically it just pushes down one lump in the carpet only for it to reappear elsewhere.

How time flies

In 56 seconds from now, the time will be twelve thirty-four and fifty-six seconds on the seventh of August 2009, or 12:34:56 7/8/9. Nice.

You'll never see that again, though for those of my generation or older, we've already enjoyed 01:23:45 6/7/89 and 12:34:56 7/8/90. I remember stopping my 6th grade class to announce the latter one. They very much appreciated my input, I'm sure.

And although I've more or less stopped offering points (they may come back again sometime, since there is nothing new under the sun), I wonder if anyone notices anything particularly apt about this image.

"Give me more time! Give me time!"

[...] to have time for another, although in the abstract this says little, is in reality to manifest in essence all the benefits which one man can show to another. When I really give anyone my time, I thereby give him the last and most personal thing that I have to give at all, namely myself.

- Karl Barth, Church Dogmatics I/2, 55.

This is how to be generous when you are rich. And of course, most importantly, God has time for us.

Ever feel like this?

I myself was exceedingly astonished as I anxiously reflected how long a time had elapsed since the nineteenth year of my life, when I began to burn with a zeal for wisdom, planning that when I had found it I would abandon all the empty hopes and lying follies of hollow ambitions. And here I was already thirty, and still mucking about in the same mire in a state of indecision, avid to enjoy present fugitive delights which were dispersing my concentration, while I was saying: 'Tomorrow I shall find it; see, it will become perfectly clear, and I shall have no more doubts.'

Heaven: not the end of the World XIII

Aliens and strangers
Augustine writes movingly of the civitas Dei peregrina, the pilgrim City of God. By this, he refers to that society of people scattered among the nations on earth who love God more than self, who glory in him, rather than seeking their own glory, who confess Christ and yearn for home, finding themselves homeless wanderers in this world. Indeed, the Latin term peregrina, often translated 'pilgrim' might perhaps be better rendered 'resident alien' or 'sojourner'. It is a word closer to the experience of Tom Hanks in The Terminal than the merry pilgrim-cum-tourists of Chaucer's Canterbury Tales.

To confess Christ is to put yourself on the wrong side of those powers that crucified him, and so to find oneself misunderstood as a rebel. Misunderstood, because just as Christ was a prophet calling the nation back to its true identity, calling humanity back to its Creator, so those who take up their cross and follow him are doing so out of faithfulness to that Creator and thus in solidarity with the groaning creation.

And like the creation, those with the Spirit - the firstfruits of the future presence of God - yearn for the redemption of our bodies, for a transformed world where death is no more, where Christ's gracious kingdom is unopposed, where the riches of God's kindness are poured out with unspeakable joy. We long for the day when the oppressor is no more and the earth is inherited by the meek.

Because of this, we can never feel at home in a world where the rich devour the poor, where unborn strangers are turned back at the borders of life, where Christ is crowned with thorns and anointed with spittle. We are aliens, citizens of the civitas Dei peregrina.

But this is not because our home is elsewhere. It is elsewhen.

And so I wonder whether when Christians are called 'aliens and strangers', this is less like the Jewish exiles in Babylon, who pined for Zion and could not sing for grief, and more like Abraham. Abraham and his immediate descendents are repeatedly called 'aliens' and 'strangers' (Gen 17.8; 21.23, 34; 23.4; 26.3; 28.4; 37.1), though they are already living in the land that God had promised them. Though strangers, the land belongs to them by promise.

For all things are yours, whether Paul or Apollos or Cephas or the world or life or death or the present or the future--all belong to you, and you belong to Christ, and Christ belongs to God.

Where When is home?

There are so many otherwise great hymns that lose it in the final verse, suggesting a gnostic flight from the world into a 'home' elsewhere, beyond the skies. Revelation speaks of a 'new heavens and a new earth', and pictures the heavenly Jerusalem coming down from heaven to earth (not the other way) - I take this (amongst other verses - this probably needs a series of its own) to mean that Christians are hoping for the resurrection of the dead onto a restored/renovated earth, not a flight off onto another world or into a disembodied 'spiritual' existence with God.

Compounding the error, many hymns seem to place this hope at the point of death, such that death becomes a doorway into this 'heavenly bliss'. While death for the believer is indeed accompanied by the promise that we will be 'with' Christ, this seems to be very much a sub-theme of the New Testament. More important is what happens after the 'afterlife' - namely, real life once more in a perfected body upon a liberated earth. Perhaps once again, there is a series of posts waiting to be done here.

For many hymns, perhaps a simple correction is available: simply replacing a locative reference with a temporal one. Instead of our hope being located elsewhere, it might be less confusing to sing of its being located elsewhen. I'd love to start compiling a list of hymns that could be improved on this point. Any suggestions?

Transience

If the solution to the human problem is a timeless eternity of changelessness,* then is our problem transience? No, because the world, the very good world, had transience built-in. The sun set before the fruit was picked. Transience is a feature of creation, not fall. Yet the fall is what makes transience deadly, what brings bitterness to old age and fear to the open horizon of the future. God created a world with a telos, a goal, a purpose, a project: be fruitful and multiply, extend the garden, serve the soil, enjoy. The world was made good, very good, not one that was utterly complete and with no more perfections to be reached.
*Is this true? Perhaps a subject for a future series...

Time for a change? Time & eternity II

My new-found Scandinavian friend Patrik has responded at length to my first post on time and eternity, which in turn was a response to some of his earlier posts (he's already done a good job of cataloging the history).

My own grip on patristics being somewhat slim, I nonetheless realise that the idea that God is somehow outside of time has a long and noble history reaching back into the first few centuries of the church. Yet I just don't buy it. Let me fly a kite and see what happens. Happy for it to be shot down...

Can God change? A fascinating question. The early fathers argued that change either means God's getting worse (and so is no longer perfect), or better (and so wasn't perfect before). However, I guess I find problematic the notion of perfection that lies behind the Greek fear of transience. I'm not sure that mathematical perfection is the most fruitful model for conceptualising divine perfections. And there's the key: perfections. God's perfections remain open-ended and so capable of growth and multiplication. For instance, although he was Father (and Son, and Spirit) without the world, he is now Creator, a new perfection. In a similar manner, the Incarnation brings about a new state of affairs for divine identity. There is more that can be said of him now. Not because he was deficient prior to the Incarnation, nor because he was already incarnate and we just didn't know it yet. But his perfections have been multiplied.

Does this threaten divine faithfulness? No, in fact, I sometimes wonder whether temporality is a condition of faithfulness. If God is outside time, then does his ability to stay true to himself constitute a virtue? Do we praise a triangle for its faithfulness - always, no matter what, having three sides?

Paul Ricoeur makes a very useful distinction between ipse and idem identity. Both are Latin words translated 'same', but with a slightly different spin. Am I the same person I was yesterday? Yes, and no. No, many of my atoms have changed, millions of cells have died, I have different memories, a slightly different outlook on life, a little less hair, a little more weight, a little more wisdom (I hope). But yes, it's still me - I'm still the same character in the story of my life. The former kind of identity (mathematically exactly totally the same) is idem identity - the same what-ness (unchanging substance). In this sense, I am not the same as yesterday. But the second, ipse identity, is the same who-ness. Self-same versus same self. I believe that God's faithfulness, his constancy, consists of ispe, rather than idem identity.

Time for eternity?

Years ago, a friend of mine said, 'at least we won't have to deal with time once the Last Day comes.'

Until that point, I'm not sure I'd ever really thought about time and eternity, or at least not in terms of time versus eternity. I'd always assumed there would still be time for time after the Last Day, after 'the end'. But apparently not. Apparently, "It is a firm belief of the Church that time will not be a part that existence," as a much-loved fellow blogger recently said. And then I looked, and behold, he was (more or less) right: for most of its history, much of the Church has been looking forward (or sideways, or upwards, or inwards, or something), for the dissolution of time, the defeat of transience through sneaking out of the whole equation into the realm of a timelessly eternal God.

Why is that? I've never felt the reason for it. Certainly Moltmann rejects any conception of a 'timeless eternity'. If time is part of God's good, very good creation (rather than part of the fall, as Augustine needs to end up saying, since he is the one who really introduced this time/eternity split), then won't it too be redeemed in the 'restoration of all things'? Moltmann develops the concept of 'the fullness of time' - at the end, every moment will be completed, summed up, gathered together, purified and transformed into redeemed time. God will have time for us, because he takes his time with us. Let's have a good time with God.
