Alister McGrath’s new book: Why We Believe: Finding Meaning in Uncertain Times will be published by Oneworld, in January 2025. He gives us a sneak preview of the theme of the book here – look out for it when it comes out.

Who can we trust? What can we trust? These are among the most difficult and cognitively demanding tasks that we face in everyday life. We look for friends who are smart, honest and dependable – just as we seek beliefs that are trustworthy and enable us to flourish. My argument in this book is that belief is natural, reasonable and has the potential for good. To deny it, to suggest that faith is only for those not willing to deal in facts, is simply to diminish us as human beings.

It is perhaps the greatest paradox that we face as human beings: we only seem to be able to prove shallow truths, but not the great truths of meaning, goodness and significance that lie at the heart of our existence and give order and meaning to our lives.

During my period as Professor of Science and Religion at Oxford University, I was able to reflect extensively on the scientific study of beliefs, which calls into question the cultural oversimplifications of recent polemics – such as those of the now-defunct ‘New Atheism,’ with its litany of unacknowledged beliefs. For some epistemic Puritans, we ought only to believe what we can prove. Logic and mathematics thus provide us with the norms that we should apply to everything in life. I share their admiration for these glittering peaks of human knowledge production. Yet these are singularities, areas of knowledge in which a degree of certainty is possible which distinguishes them from other domains of human understanding, rather than being representative of them.

The ideas I have been exploring in these past years and that you’ll find in this book are not new; in fact, they have a distinguished history in the long tradition of philosophical reflection and religious faith, which are deeply attuned to the problem of uncertainty.

My position is this: believing is not only intellectually defensible but existentially necessary. It’s time to move on from movements and individuals who offer facile solutions in the face of life’s endless ambiguities, and face up to the critical importance of beliefs in shaping and sustaining meaningful human existence. Believing is a human stance to be embraced, not a liability that is to be eradicated.

In the end, we are all believers, whether we like it or not, whether we are religious or secular, in that our lives and knowledge are grounded and shaped by assumptions and beliefs that lie beyond comprehensive empirical verification or rational proof. Living in this vast space of ambiguity and uncertainty is an art, a skill that we have to learn.

Happily, as this book will show, it can be done.

Why We Believe will be published on 25 January 2025, By OneWorld.

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.”
