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.

The Rest is Luther

Did 'The Rest is History' get Luther right? Graham Tomlin gives his verdict

Graham Tomlin

Graham is the Director of the Centre for Cultural Witness and a former Bishop of Kensington.

Two podcast hosts in different rooms appear on a split screen talking to each other

Tom Holland and Dominic Sandbrook rank Luther's influence.

I have to confess, I don't listen to every episode of The Rest is History - does anyone do that with the astonishing volume of material they produce? Yet when I see something that interests me – 1970s Britain, the Lost Library of Alexandria, the Easter Rising of 1916, I’m in. So, when I saw they were doing a series on Martin Luther, I just had to listen.

With much of what they cover - take the Lost Library of Alexandria for example - I wouldn’t really know whether they were telling the truth or not, having a passing interest and only a vague knowledge of the topic. Yet this one was different, because, without wanting to blow any trumpets, I do know a fair bit about Luther. I’ve written a doctorate, a biography and a couple of other books on him, lectured on Luther at Oxford University for many years, and spent a lot of time in libraries, poring over his commentaries and treatises, wading my way through dense books by German scholars picking apart the most minute aspects of his theology.

Very often when you hear something on the TV or radio that you know something about, you realise the journalists are winging it. They get away with it because no-one knows any better. So, I wondered this time, would I see through the boys on the podcast, and realise they were winging it too?

They made the Reformation sound and feel the dramatic and earth-shaking movement that it was.

Well, my admiration for Dominic Sandbrook and Tom Holland went up massively. It was brilliant. I once asked Tom whether they had an army of researchers doing their work for them and he told me they didn’t - they read most of the stuff themselves. So, to have them do five episodes on a topic that is not necessarily their specialist subject and get pretty much all of the story not just right, but really interesting, is quite an achievement. They made the Reformation sound and feel the dramatic and earth-shaking movement that it was.

They normally recount history with a good dose of humour, drama and colour. That is taken for granted. They know how to tell a good story. However, they also really know their stuff. Tom led the way, and I must say, told the story with a level of detail, accuracy and sympathy that was quite remarkable. They clearly enjoyed it too – they loved his earthiness, his preoccupation with the devil and excrement that is so distinctively Luther.

Martin Luther, as they said at the end, was no saint. He was a man of extremes. He could inspire devoted loyalty from his friends, and fury from his enemies in equal measure. He was never dull. He always said his besetting sin was anger – he claimed to write best when he was furious. That explains the vituperative language, the skill at invective, his genius for insults. He said terrible things about the peasants and even worse things about the Jews. Yet he also launched a movement that brought fresh dignity and purpose to countless people across Europe and beyond – he can be said to have touched the lives of the one billion Protestants in the world today. He literally changed the world. And Tom and Dominic helped us understand why.

Definitely a nine out of ten.

But why not ten?

Well, I did have one small quibble. Luther was portrayed as someone who struggled to know that God loved him. So far, so good. His great breakthrough was described by the excellent Tom Holland as “a personal experience of God”, whereby Luther found “a feeling of being washed in the love of God.” Luther’s new discovery was that “If God loves you, you exist in a state of grace… which is a feeling that Christ is present in you, in your secretmost heart, and the certainty of that grace gives you a peace of conscience.”

Now there is something of that in Luther, and it was close, but it’s not quite the way he would have put it.

Luther is really not that interested in experiences of God. In fact, he distrusts them. in 1521, a group of prophets arrived in Wittenberg from a small town called Zwickau claiming experiences of God, but Luther was having none of it. He asked about their experience – but not whether they had experienced the love of God, but whether they had experienced his absence. Had they experienced what Luther called Anfechtung – the experience of feeling God is against you, when you struggle with temptation, are driven to despair, when God doesn’t answer your prayers, and when all you know is your own shame, sin, and disgrace? What do you do then?

And that’s why the Bible was important to him – as an existential anchor when the storms of life hit.

The reason he asked about this was that such experiences so often are the things that help bring faith to birth, because they press the question of who you listen to, or trust, in such times – your own feelings of inadequacy and shame? Or God’s word that tells you something different?

Luther found peace of conscience, not in a mystical experience of the love of God, but in hearing again and again the Word which God had spoken to the human race in Jesus Christ. Against all the odds, and despite his frequent experience of God’s absence rather than his presence, he recalled that God had sent his Son, as a pledge once and for all, that God’s heart was full of love and kindness. In sending Christ, God had given himself (or technical language, his ‘righteousness’) to us in Christ, and the only fitting response, was simply to believe and trust that this is true, whereby that ‘righteousness’ becomes ours, and we are, to use Luther's language, 'justified'. Christians are therefore, in Luther’s classic and paradoxical phrase, ‘both righteous and sinful’ at the same time.

This was indeed profoundly emotional for him. It brought a flood of joy and relief. Yet that joy was the result of faith in faith in the Word, which was the main thing. The emotions followed faith, not the other way round.

He once put it like this: “God achieves his purposes through suffering, pain and anxiety. Yet of course these are not the things in which you expect to find God. As a result, most people do not recognise this as God’s work, because they expect God only to be revealed in glory, grandeur and splendour. The way God works confounds human expectations and so, faith is needed to see past the appearance of things to their true reality.”

This was the doctrine of justification by faith – not trying to be extra religious or having ecstatic experiences of God but simply betting your life on the notion that Jesus is God’s great gift to the world, a gift that tells us he is, despite everything that may point in the other direction, full of love and goodness – and not just to the human race in general, but to you, to me. And that’s why the Bible was so important to Luther – as an existential anchor when the storms of life hit.

Tom and Dominic did a fantastic job in their series on Luther. I really recommend you listen to it – you won’t regret it. Only remember, Luther relied more on faith in the Word of God than the fleeting feelings of his heart:

“Faith is a living, bold trust in God’s grace, so certain of God’s favour that it would risk death a thousand times trusting in it. Such confidence and knowledge of God's grace makes you happy, joyful and bold.”
