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.

I wrote Jesus was a child refugee, I got called crazy

Digging into history uncovers uncomfortable truths.

As a historian of Jesus, I have sometimes been asked to comment on the question 'what would Jesus do today?'. I have sometimes responded. In September 2015 I wrote a guest post for the Jesus Blog, titled Jesus was a Refugee. It was on the story of baby Jesus’ escape to Egypt with his parents, as written in the Gospel of Matthew, which I conclude is historically true. It is interesting to me, because I want to understand what informed Jesus’ teaching as an adult.

I am not a theologian, a priest or a pastor. I have spent my academic career carefully working out what is true or false in terms of the many stories of the ancient past. So, when I discuss anything, it is after years of study, collegial discussion and discernment. Historians like me know that our ancient accounts come from particular people at different times, telling things with particular points of view. They don’t seek to tell the whole truth, but they shine a light on what is important to them. They can tweak, spin, modify or drop what is not essential to them, and we see this process unfold in retellings. In what I do, I am as analytical about biblical stories as I am about anything else, recognising that I too am located in a particular time and place, with my own capacity to see or not see. With biblical stories this is both rewarding and challenging because to me they are also Scripture, in that they inform my faith, spirituality and practice.

But this is a world in which sharing of expertise can go up in a puff of public pushback.

I wrote at the height of scaremongering about Syrian refugees who were fleeing to Europe to escape the dangers and devastation in their country and, given its relevance, the post was picked up on other sites. On Bible History Daily, there was a furious reaction in comments. People asked whether – even if Jesus was a refugee – his experience could be mapped on to issues of the contemporary world, which are so very different. Some commenters insisted that Jesus and his family could not be aligned with economic refugees like Mexicans or bogus refugees who were actually Muslim terrorists. More stingingly, I was told I was crazy, a professor of b******t and I was blaspheming for even suggesting that Jesus was a refugee.

That Jesus was a refugee has actually been recognised as part of his life from the very beginning of Christian tradition, and contemporary theologians like Barnabas Asprey can well explore what this means for faith. But it seems that some people were alarmed that I was diminishing Jesus by associating him with people they considered reprehensible.

My job is to understand Jesus in his own world. If I do it properly, people may well find resonances with today. But I do also understand that it is a tricky thing to map Jesus onto contemporary circumstances, especially contentious ones. Over a hundred years ago the philosopher and physician Albert Schweitzer critiqued the 'quest of the historical Jesus' as a whole as covertly creating a liberal model of Jesus. He commented that the 'historical Jesus will be to our time a stranger and an enigma'. If we met Jesus today, he would seem completely alien to us. So, we do have to be careful when we look to him in our arguments concerning current issues. Yet, Schweitzer also put a lot of trust in the words of Jesus, because his 'spirit, which lies hidden in his words, is known in simplicity, and its influence is direct. Every saying contains in its own way the whole Jesus.'

So where do we go with this? What did Jesus say? Frankly, Jesus’ ethos was utterly uncompromising. "Woe to you who are rich … woe to you who are well-fed now" (Luke 6:24-25), he said. There are a decent number of Jesus’ statements that suggest people who were economically struggling should be fed and welcomed, and those with wealth should share what they have with the have-nots. Jesus said to a rich man that he should "go, sell all that you have and give to the poor, and you will have treasure in heaven, and come, follow me" (Mark 10:21). Following Jesus was not about becoming destitute, but about joining a community of disciples who saw each other as one big family of siblings. In this group resources were shared (Acts 2:44-45 and 4:32-37). This is beyond philanthropy. And Jesus didn’t talk about the worthiness of the poor; the problem was not with the poor, it was with the rich.

There’s a big question then in how to use Jesus as a model for ethics. To use Jesus as a model, you have to see the bigger picture of the whole movement he created, within an ancient context, a movement that does not exist any longer in its original form. Was Jesus a refugee? By calling anyone a refugee, in antiquity, I mean someone who flees their home to a place of refuge, to escape danger or disaster. As for my particular 'blasphemy', I reiterate it. Jesus was a child refugee: Jesus’ family fled from the danger of the Roman client king in Judaea, Herod, and escaped to Egypt. In classical Christian doctrine, this is not at all thought of as diminishing Jesus. It made Jesus one of us, in all our human hardships.

I think he turns things around, radically, so that the life of the wandering refugee is actually a paradigm for action.

Curiously, the fears expressed by the commenters on my post mirror ancient attitudes to poor, foreign people. Later apocryphal stories of the holy family in Egypt present them facing continual hostility from Egyptian townsfolk and attacks by robbers. These tales reflect an actual situation in which incoming foreigners, for whatever reason, were not welcome. For refugees, it could be a life of vulnerability. In the second century, the anti-Christian writer Celsus scoffs that child Jesus in Egypt worked for hire because of his poverty (Origen, Contra Celsum 1:28).

Egypt itself was not a totally safe place to be Jewish. Under the Roman prefect Flaccus (38-39 CE), soon after Jesus, there were riots and pogroms against the Jewish population of Alexandria, as the historian Josephus records (War 2:487-98; Ant. 18:257-60). In 41 CE the Roman emperor Claudius cautioned the long-settled Jewish population of Alexandria that they lived in 'a city not their own', and they were 'not to bring in or invite Jews who sail down to Alexandria from Syria[-Palestine]' (CPJ I:151). Later in the first century (70-73 CE), there were many Jewish refugees fleeing dangers in Judaea by going to Egypt (War 7: 407–419). Hundreds of these men, identified as troublemakers by the Romans, were killed, along with their families. I explore this and much more in my new book, Boy Jesus: Growing Up Judean in Turbulent Times. The life of a refugee was hard, and Jesus would have been told his parents’ stories about what they endured.

This is what is so interesting to me, because we know from contemporary studies of trauma that this would have had an impact on Jesus. There is received trauma resulting from the suffering, persecutions, hardships and distresses of parents and grandparents.

So how are these experiences reflected in Jesus’ sayings? I think he turns things around, radically, so that the life of the wandering refugee is actually a paradigm for action. Jesus, in his mission as a teacher and healer, identified himself as a displaced person: "Foxes have holes and the birds of the air have nests, but the son of humanity has nowhere to lay his head" (Matt. 8:20), he said. Jesus was itinerant, and he entered villages with nothing, offering healing and looking for kindness (food, shelter). He asked those who acted in his stead to go out without money or extra clothing, essentially to walk along the road like destitute refugees who had suddenly fled from home, relying on the generosity and hospitality of the ordinary people whose villages they entered (Mark 6.8-11). And it was precisely the villagers’ welcome or not to such people that showed what side they were on when it came to divine justice: "And if any place will not receive you and refuse to hear you, shake off the dust on your feet when you leave, for a testimony to them" (Mark 6.11).

If the sayings of Jesus show his spirit, time and again this spirit rests with the experience of the marginalised, the displaced, the persecuted, the sick and the poor. I say this as a historian, thinking of Jesus in his own time. How that sits with contemporary issues remains a question. To what extent can people of modern times, with all our baggage of private ownership, debts and anxieties about our jobs and livelihoods, share in Jesus’ ethos? In answering it, I suspect few of us will feel comfortable, whatever side we think we are on. But taking out the logs in our own eyes, rather than the specks in someone else’s, has never been easy.
