a had holds out a small wrapped Christmas present.

I came of age in the 2000s, a decade quite alien to us now. We saw ourselves as pioneers of technology, as the internet emerged in its prehistoric form. There was great optimism about the economy until it all went wrong in 2008. The New Atheism movement was roaring into public view, only to wane just as quickly the decade after. Growing up as a Christian, I remember spirited debates with my peers about whether science disproved Christianity and if God can be disproven. These questions have fallen out of view, just as many of its main proponents have too. Richard Dawkins rarely darkens the door of our TV screens anymore.

However, one such moment of conflict sticks out in my mind. A friend announced to me that he had disproved the origins of Christianity. The night before he had discovered that in the third century Roman Empire, before Christianity became legal and the official religion, there was already a festival celebrating a god on the 25th of December. Instead of the birth of the Son of God, the Romans celebrated the rebirth of the Unconquered Sun — Sol Invictus. Then, in 336 under the first Christian Emperor, Constantine, that date was first celebrated as the day of the birth of Christ. My friend considered the case to be closed; surely the birth of Christ was merely a repurposing of an existing festival?

Thankfully this shocking revelation did not pick away at the foundations of my faith. I continued, and still continue, to believe in and love the Christian God, as revealed in the Bible. Indeed, since that moment I have trained as a scholar in the history of the early Church, and have begun to see this question for what it is, a quirk of history.

We, therefore, celebrate Christ’s birth on the 25th December on account of a quirk of history, a result of the way that Romans mapped significant events on to the waxing and waning of the light.

The first claim that Christ was born on the 25th December appears in the third century. Sextus Julius Africanus, a Roman Christian historian, wrote an entire chronology of the world from creation to AD 221. He considered March 25th to be the date of creation, because it was the spring equinox in the Roman Calendar, a day which represents new life and new birth. For this reason, he likewise considered it to be the date of Christ’s conception in the womb. Crucially, nine months after that falls December 25th. Although I admire his logic, it is hardly a sound basis for establishing the date of our Lord’s birth. Indeed, other Christians didn’t accept this claim at the time either.

As already mentioned, December 25th was a significant date in the Roman calendar already. It was the winter solstice, the shortest day of the year, after which the days begin to lengthen. It also shortly followed the popular Roman festival of the Saturnalia. Already endowed with significance, it is unsurprising that the Romans began to celebrate the rebirth of Sol Invictus, and the birth of another god, Mithras, on that date.

At this time Christianity was an illegal religion, persecuted in some parts of the Roman Empire. However, in 312, the emperor Constantine converts to Christianity and in 313 makes it a legally tolerated religion. At this point he begins to invest the church and Christians with powers, wealth and privileges. Evidence from the Chronography of AD 354 suggests that Christmas was first celebrated on the 25th December in 336, during the reign of Constantine. Perhaps this was an attempt to dislodge existing pagan holidays, and replace it with a Christian one. Or, maybe the significance of the Winter solstice made that date most plausible. Indeed, it is easy to see how the commemoration of Christ coming into the world is particularly salient as the darkness begins to recede. The true answer is, of course, lost to history.

We, therefore, celebrate Christ’s birth on the 25th December on account of a quirk of history, a result of the way that Romans mapped significant events on to the waxing and waning of the light. The true lesson here though, is that it simply doesn’t matter what the actual date of Christ’s birth was. Our records, and those available in the early church were simply not good enough for us to ever know. What matters is that God loves us so much, that he became human to bring us back to his side in everlasting joy and peace. We have no idea on what date Christ was born. But, each year the 25th December presents a time for us to remember that God became man, so that we might have everlasting life.

What have Easter bunnies to do with the resurrection?

As we emerge from the Easter weekend, Graham Tomlin unpacks why Easter is more than an illustration of new life.

the first signs of Spring breaking through

Bunnies, chocolate eggs, crocuses. It’s that time of year again. The dark bleakness of winter is giving way to life and colour as the soil warms. We finally feel sun on the skin, wake up to early dawns and longer days.

Across the world, festivals celebrate the coming of Spring. The Qingming Festival is a traditional Chinese carnival, also known as Tomb-Sweeping Day, observed by ethnic Chinese people across the world as a celebration of the new season. In the festival of Holi, Hindus across the world douse each other in brightly coloured powder or water, as a celebration of burgeoning love, and a prayer for a good harvest from the new growth in the land. The turning of the year, bringing new life, seems one of the most elemental forces in the universe.

In 1890, the Scottish anthropologist James Frazer published a book that was to become famous: The Golden Bough. It was one of the first works of comparative religion in an age which was gradually becoming more knowledgeable about the religions of the world. In it, he identified a motif in many of the world’s religions: the concept of a dying-and-rising god. He saw the pattern repeated in fertility rites connected to the annual renewal of nature from the ‘death’ of winter. Gods like Osiris, Tammuz, Adonis and Attis, Dionysus - and Jesus - were examples of the same pattern.

The turning of the year, bringing new life, seems to be one of the most elemental forces in the universe.

These days, you often hear a similar version of this account. Christianity, we are told, is another form of the same story found in so many religions. Christians just took over and erased the earlier annual celebrations with their own version. Christmas was just a replacement for Yule, the ancient pagan winter festival. Easter recalls Eostre, a spring goddess from western Germanic lands, whose festival took place in April, connected to the spring equinox.

Today, we have lambs, daffodils, young rabbits and eggs. All of them emerge at this time of year and are, for us, signs of the rebirth of nature. It always seems miraculous, that from the deadness of winter, life is reborn. No wonder the ancient pagans, and religions all over the world, for that matter, found ways to celebrate new life, and to endue this season with mythical wonder.

It was tempting for James Frazer to bracket Jesus as just another of these myths of the death and rebirth of nature, the dying and rising god. Bunnies, eggs, Osiris and Jesus were all symbols, pointing to the same thing – the annually repeated miracle of new life in the Spring.

Yet this misses the point of what the early Christians said about the Resurrection. St Paul wrote: “Christ has indeed been raised from the dead, the firstfruits of those who have fallen asleep.” His point was precisely not that this event was another illustration of the annual renewal of nature, the cycle of death & rebirth. It was something new altogether. It was the once and for all breaking of the cycle, spelling the end of death and its repeated power over us. Christ breaks through the dark wall of death so that millions of other can follow him through the breach into the light beyond it.

It was not another annual temporary suspension of the inevitability of death, it was the breaking of the power of death once and for all, pointing to its final defeat one day.

The Resurrection of Jesus was the ‘firstfruits’, like the very first crocus of spring, the first apple on the tree. It was like a man breaking the four minute mile, a human being walking on the moon. A barrier had been broken that had always seemed impregnable and nothing would ever be the same again. It was the beginning of an entirely new creation that will one day come into fullness. It was not another annual temporary suspension of the inevitability of death, it was the breaking of the power of death once and for all, pointing to its final defeat one day. The endless cycle of rebirth is suddenly folded out into a linear trajectory, pointing forward to the day when all shall be made new.

CS Lewis attributed his conversion at least in part to a conversation with JRR Tolkien which persuaded him that the story of Jesus – his incarnation, descent into death and resurrection to new life - was not just another example of the ancient myth of the renewal of the world, but was the thing towards which all the myths pointed – it was, as he called it in a famous essay, ‘myth become fact’. It’s worth quoting him to get the point:

Christianity is a myth which is also a fact. The old myth of the Dying God, without ceasing to be myth, comes down from the heaven of legend and imagination to the earth of history. It happens—at a particular date, in a particular place, followed by definable historical consequences. We pass from a Balder or an Osiris, dying nobody knows when or where, to a historical Person crucified (it is all in order) under Pontius Pilate.

Of course, there will be echoes of resurrection in the other faiths of the world. Of course there will be pagan figures who look like Christ. Rabbits and eggs are to be enjoyed not frowned on as they point to the one great miracle. They are to be welcomed, not disowned. Lewis’ point is that the Resurrection is both myth and fact – myth become fact. The Resurrection doesn’t just point to the rebirth of the world. It is the rebirth of the world.

Now of course, Christians can’t prove it. They can, to be sure, point to evidence that the tomb was empty, that the profound, world-shattering effect on the disciples and even the rest of human history can only be explained by something truly extraordinary. But you can’t prove an event that by its very nature breaks the normal cycle of cause and event, death and rebirth, proof and disproof. You can only believe it and then re-build your whole view of the world around it. As theologian Lesslie Newbigin put it:

“At the heart of the Christian message was a new fact: God had acted in a way that, if believed, must henceforth determine all our ways of thinking. It could not merely fit into existing ways of understanding the world without fundamentally changing them. It provided a new arche, a new starting point for all human understanding of the world. It could not form part of any worldview except one of which it was the basis.”

So, no, we can’t prove it. But we can at least do the early Christians the justice of acknowledging what they were saying and what they weren’t.

Because this is the central Christian claim – that the Resurrection is not a metaphor for something else – for the rebirth of nature in the spring, or for the fertility of nature. In fact, it’s the other way round. The rebirth of nature is a metaphor for the Resurrection. The Resurrection of Jesus is not an illustration of something else. It is the one thing of which everything else is an illustration. In the light of the Resurrection, the renewal of nature in spring is not yet another round in the endlessly repeated cycle of death, rebirth and death again, but it points forward to the day when “the trumpet will sound, the dead will be raised imperishable, and we will all be changed.”
