Star of wonder and beyond

From the Christmas star, humankind has been fascinated by astronomical possibilities.

The James Webb Space Telescope was launched on Christmas Day 2021. After hair-raising maneuvers to unfurl its tennis-court-sized mirrors, it has been sending back breathtaking images of the cosmos since July of last year.   

Christmas was a good day for the launch, given its astronomical connections. ‘Glory to God in the highest heaven’, the angels sang to the shepherds, ‘and peace to his people on Earth.’ Meanwhile, the wise men were above all diligent observers of the heavens. ‘Where is the child who has been born king of the Jews?’, they ask, ‘For we observed his start at its rising, and have come to pay him homage.’  

Quite what that ‘star’ might mean there is open to debate. Comets have been popular with artists. Giotto painted one, for instance, in his Adoration of the Magi in the Scrovegni Chapel in Padua. It is almost certainly Halley’s Comet, which had appeared just a few years before, in October 1301. But why would anything in the heavens be interpreted as a birth in Judea? It would probably involve something in a constellation associated with the nation of the Hebrews. Pisces seems to be favoured, for some reason. A nova of some kind is one possibility: what would look like a temporary new star because, in fact, a previously invisible star was undergoing a spectacular death. Chinese records suggest a nova in 5 BC, which fits the likely date for for Christ’s birth of 7–2 BC. 

The problem with both comets and novae is that they were more likely seen as harbingers of doom than good news. The better candidate for suggesting something joyful is a planetary conjunction, and there would have been a rather spectacular conjunction of Jupiter, Saturn, and Mars at the right time. None of that, admittedly, explains what it means for the star then to have led the wise men. Coming up against that challenge, we might think that looking into the astronomical detail is the wrong way to approach the story. Nonetheless, Matthew had something in mind when he wrote about a start in his gospel, and it’s worthwhile to ask what that might have been. 

It might be fitting for God to deal with other species as intimately as God has dealt with us, so that they might see ‘God made visible’ in their own nature, as we see God made visible in ours. 

More recently, the Christmas story has intersected with astronomy in questions about how to think about Christian theology now that we are aware quite how big the universe is, especially if it may contain a great deal of other life. We don’t know whether that’s true, of course, but given we now know that planets common around stars, and there are billions of billions of stars in the universe, the probabilities seem to tilt towards other life, at least as I see it. 

Suggestions surfaces from time to time that the world’s religions have arrived late to the party, when it comes to thinking about life beyond Earth. The astronomer and broadcaster Carl Sagan made that claim, for instance, in his best-selling book Pale Blue Dot. In fact, the earliest discussions of life beyond Earth I know about from Christian writers come from the mid-fifteenth century (and they stretch even further back in Judaism and Islam, to give two other examples). Christian writers have written on the subject ever since. If few gave us more than a paragraph here or a page there, that’s usually because the prospect of other life did not worry them enough to warrant more. They noted the prospect cheerfully, and moved on.   

Until the twentieth century, the prospect of parallel Nativities on other planets was rarely in view. In a sense, it didn’t need to be. It’s a consistent Christian position to say that God joined his life to all creation in joining it to one species of rational animal on Earth, just as God joined his life to all humanity in being born in a stable, in a wayside town, in a backwater province of the Roman Empire.  

One erudite early exploration of multiple Incarnations comes in a poem from the 1920s by the Roman Catholic poet Alice Meynell, entitled ‘Christ in the Universe’. More recently, Meynell’s topic has become perhaps the central theme in thinking theologically about life beyond Earth. My own book (Astrobiology and Christian Doctrine, 2023) looks at the prospect of life beyond Earth from the perspective of all of central topics in Christian doctrine (creation, sin, redemption, revelation, the Trinity, and so on), but the largest section is on Christmas and possible parallels. I am sympathetic to the idea that God would also unite himself to another natures, alongside the human nature he took up in Christ: not because I think that would be necessary, but because it might be fitting. It might be fitting for God to deal with other species as intimately as God has dealt with us, so that they might see ‘God made visible’ in their own nature, as we see God made visible in ours. 

Hiding in plain sight in the Nativity stories is another key to Christian thinking about life beyond, namely the angels. It’s not that I think that angels are aliens, or that alien life is angelic. In fact, being a disciple of St Thomas Aquinas, I’m inclined to view angels as entirely immaterial, and so very much not examples of biological life. But angels are useful for thinking about other biological life beyond Earth nonetheless, because of what they mean for the Christian imagination. The angels show that there’s always been space in that imagination for rational creatures other than human beings. They show that Christianity has never imagined that we’re the sole object of God’s love, or even the most glorious of species.  

The Christmas story has its cosmic elements: the star, glory in the highest heavens, and the angels, reminding us that wonderful though humanity is, it has no monopoly on rational life. My hunch, as much as my hunch matters, is that if there is other life then they too may see God face-to-face in their own Incarnation. Even if we find evidence of life beyond Earth, however, it’s not going give us much detail. The balance of gases in the atmosphere of a planet around another star might indicate life, but not much else about it. The prospects for interplanetary comparative religion are far off indeed. Alice Meynell had the right idea, when she recognised that one of the joys of the life of the world to come will be learning the stories of God’s dealings elsewhere: 

  

But in the eternities, 

Doubtless we shall compare together, hear 

A million alien Gospels, in what guise 

He trod the Pleiades, the Lyre, the Bear. 

  

O, be prepared, my soul! 

To read the inconceivable, to scan 

The myriad forms of God those stars unroll 

When, in our turn, we show to them a Man.

How to have a philosophically happy Christmas

Raise a glass to the invasion of history by the author of history.

Professor Charles Foster is a Fellow of Exeter College, Oxford, and a member of the Oxford Law Faculty.

A few years ago, I had dinner with a well-known philosopher. Knowing that he is no friend of religion, and curious how he’d respond, I set about mocking the credulity of Christians and parroting the lines I’d so often heard: superstition degrades and obfuscates; let’s act and think like grown-ups, not craven children; we’re free to write our own rules, and we can write better rules than barbarous Levantine goat-herders; we’re brave enough to say that when we die we rot. And so on. The standard fare.  

He looked at me over the top of his glass. ‘Have you never been taught’, he said acidly, ‘that if you destroy the premises of an argument, the argument collapses? The same is true of history.’ 

I’ve slowly learned that he was right.  

‘What have the Romans ever done for us?’, asked John Cleese, as the leader of the People’s Front of Judea. He’s famously answered by his troops. The modern version of the question, which is just as embarrassing, is ‘What have the Christians ever done for us?’  The historian Tom Holland, not (as far as we know) himself a professed Christian, has made a good living by providing a long and meticulously documented list. I’m not going to review it here.  My own personal list would include Chartres Cathedral, Paul’s tectonic notion that there is ‘neither Jew nor Greek, slave nor free, male nor female’ (and hence universal human dignity and suffrage), and Christmas

The Christians say that Christmas is the commemoration of a historical fact: an invasion of history by the author of history; of creation by the creator.  

This is too much for many to swallow.  If that’s true for you, is it dishonest to celebrate Christmas? 

A mathematician friend works on imaginary numbers. An imaginary number is a real number multiplied by the ‘imaginary unit’, i. i2 = -1, and so i = √-1. Think about it. It’s an impossibility. It’s absurd. Descartes talked about ‘imaginary numbers’ only to laugh at the idea. But they are enormously useful in real life. You are reading this on a phone or computer screen courtesy of imaginary numbers. Sometimes it’s worth suppressing, or at least muting, a contemptuous laugh. Tom Holland’s list, and mine, depend on theological and historical numbers that might (or might not) be imaginary. You don’t have to stop dubbing the numbers ‘imaginary’ – don’t stop having to call them ludicrous – to carry on reading your screen.  

Christmas, for me, is a celebration not only of family, gluttony and intoxication, but of four facts (if the Christians are historically correct) and four principles which are generated by those facts - whether the facts are real or imaginary. The principles work, just as my computer screen does. 

First: human agency is cosmically colossal. The invasion I mentioned above was invited (so preventing it from being rape) by a Palestinian Jewish girl. She could have said ‘No’, and so scuppered the whole project.  

Second: Christmas drafts a completely new account of power. In the Christian story of Easter, all the powers of darkness are disarmed by one broken man dying on a piece of wood between dying criminals. It was a continuation of the story that began at Christmas: the birth, in a shitty stable, to a teenage mother accused of fornication, of a child soon to be a refugee, driven to another country to escape the murderous authorities. It’s all about the subversion of political and military power by the irresistible power of the powerless.  

Third: the universe is surprising. Nobody predicted the invasion. Yes, I know the Christians say, with the confidence given by the retrospectocope, that there were hints in the Hebrew scriptures, but they weren’t seen at the time, and the most learned Jews today, even with the retrospectoscope, still don’t see them. Yes, I know that the ancient world was awash with tales of the impregnation of mortals by gods, and with virgin births (think of Dionysos, Attis, Romulus and Remus and many others). But they didn’t look remotely like this. Those tales were told to prop up conventional claims to power, not explode them. Bethlehem burst onto the blind side of history, injecting unforeseen possibility. The virgin conception smashed pre-conceptions. A new way of being had gestated. If that was possible, what wasn’t?   

Fourth: The most revolutionary thing about Christmas, perhaps, is that it shows that mythos is real – part of the web and weave of reality.  

After dinner at Magdalen College, Oxford, on 20 September 1931, J.R.R. Tolkien, C.S. Lewis and Hugo Dyson walked together along Addison’s Walk, part of Magdalen’s grounds. They were discussing the resurrection of Jesus. Lewis knew all about the ubiquitous tales of dying and rising gods. The Christian resurrection stories were no different, he said. They were poetically resonant, no doubt, but essentially ‘lies and therefore worthless, even though breathed through silver.’ 

‘No’, said Tolkien. ‘They are not lies,’ There was a sudden rush of wind in the still night. In Lewis’s rooms the conversation continued into the early hours. The stories were indeed myths, Tolkien contended, but true myths.  

This conversation propelled Lewis finally into Christianity.   

The Christmas story suggests that Tolkien was right (and those notoriously mystical quantum physicists – some of the most adept handlers of imaginary numbers, by the way - are right): there is no robust boundary between history and legend, between physics and metaphysics, between matter and spirit. This, in fact, is our working assumption, whether we’re explicitly religious or not. However icy our reductionism, we think that we matter, that there is more than matter, and that whatever that ‘more’ is, it is heavier and more enduring than matter, and matters more than matter. We love our children far more than reciprocal altruism or kin selection suggests we should. However sturdy our atheism we dab our eyes at the St Matthew Passion and put flowers on our parents’ graves.  

It is reassuring to have a festival which enjoins us to lift our glasses and toast the way we live when we’re being the kind of people we urge our children, our friends and our politicians to be. It commands us to admit mystery to the dining table, and to celebrate being as mysterious as we know we are.  

Christmas, authentically celebrated, is part of the foundation on which rest Chartres cathedral, freedom, suffrage, dignity and many things we innocently and dangerously take for granted. Like it or not, that foundation, as the austere philosopher observed, is the premise of the argument for the civilization that until recently succoured us before we replaced it with – well, with what?
