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.

Those unexpected angel stories

Shedding a strange light on a disenchanted world.

Unlike Robbie Williams, who sings about them, sometimes I preach about angels. When I do something always happens – people start telling me their own angel stories.

There was the one a soldier friend told me. During an army climbing expedition to Mount Kenya, one of his team had fallen to his death from a sheer rock face. Caught up in the drama of the moment, my friend found himself stuck on a ledge, unable to move up or down, paralyzed by fear and frustration. Suddenly, in an inaccessible part of the world, where they had seen no-one for days, on a mountain where they were the only registered group present, a climber appeared out of nowhere, moved onto the ledge where he was standing, tied a rope into his harness, lowered him down the rockface to safety before disappearing up the face never to be seen again.

Or the story of a pastor who got into trouble in an airport. A stranger walked by and asked if he could help, and remarkably fixed a seemingly intractable problem. The grateful passenger took a selfie of himself and the stranger, but when he looked at the phone later on, there was a picture of himself, grinning into the camera, with his arms around… nothing.

Why do so many stubbornly believe in angelic beings, when a materialist view of the world laughs scornfully at the idea as a bit of pre-modern superstition?

These are not just modern stories. In the second century, a young man called Justin from Asia Minor was working his way through the various schools of Greek philosophy. One day, he was walking along the beach at Ephesus, wondering, as young people have always done, about the meaning of life in general and his own life in particular, when a mysterious old man came alongside and joined him in conversation. As they walked together, the old man spoke about the philosophers and how none of them were quite able to answer the deepest mysteries of life. He advised Justin to read the Old Testament prophets, before disappearing into the distance. Justin did so, became a Christian and went on to become one of the greatest early theologians of the Church and one of its early martyrs for the faith – hence the name he is remembered by today - Justin Martyr.

Was it an angel? Or a real, yet mysterious old man? Are angels real? And if so, what is the point of them? Surveys tell us that 30 per cent of British people believe in angels. In the USA that figure rises to 70 per cent. Why do so many stubbornly believe in angelic beings, when a materialist view of the world laughs scornfully at the idea as a bit of pre-modern superstition? After all, the cynic might say all these stories can be explained - these were just ordinary people who turned up unexpectedly.

The encounter opened the eyes of the person in the story to another realm, a world unseen yet just as real as the seen.

The word angelos in Greek simply means messenger – and it can mean either a human or an angelic one. In the Bible, angels don’t usually appear with glowing white clothing and wings sprouting from their shoulder blades. When they come to people with a message, they often appear in the guise of ordinary people. In fact, it’s often hard to tell whether you have been visited by an angel or just another human.

The point, therefore, is not so much about the angels, but about the message that they bring. They tend to turn up when there is something particularly important to announce, something like the birth of Jesus, when an angel appears to the young Mary to tell her the news that she will give birth to the Son of God, her, and then quite a few of them turn up to sing to the shepherds, an indication that something big was happening.

In each of the stories above, the encounter opened the eyes of the person in the story to another realm, a world unseen yet just as real as the seen. An inexplicable encounter with what just might have been an angel has the capacity to open our eyes to the fact that the world is bigger than we often assume – that as Hamlet says to his dull, practically minded friend: “There are more things in heaven and earth, Horatio, than are dreamt of in your philosophy.”

The Nicene Creed, the classic summary of Christian faith, speaks of God as the ‘Creator of all things seen and unseen’. We are all used to what we can see, yet some of us only have space in our world for things that can be seen, touched or measured. Yet there are surely those unseen realities – things we cannot see or measure, like love, compassion, holiness, miracles, God and - yes – angels.

A random sermon on angels elicits hushed stories that people feel almost embarrassed to speak. Such mysterious experiences are far more common than we realise, as Dan Kim points out elsewhere on this site. Yet these experiences are not an end in themselves but are perhaps a way of God getting our attention when we refuse to listen to more ordinary approaches. These experiences open our eyes to a dimension of reality that is as real, if not as visible as the one we deal with every day – and become a gateway to a journey of discovery of an unseen world alongside the seen, that sheds a strange but welcoming new light onto a disenchanted world.
