Christmas makes no sense without Easter.

In Jesus of Nazareth, the Creator himself entered his creation to live among us. This is what Christians call the Incarnation. But why? What was the point of this identification with humanity? You might have expected these sorts of answers: he came to found the Christian religion, to teach us how to live and to gather a community of followers. These are true enough but look inside any church building or read any part of the New Testament, and you’ll find that another thing is the focus, something that makes Jesus different to any other founder of a religion. He came to die.

Jesus’ death is the climax of all four gospel stories. It is evident that the point of the narrative is there. The rest of the Bible’s New Testament spends more time describing the machinations that led to Jesus’ death than outlining what he taught. Does that mean it doesn’t matter what Jesus taught? Of course not: Jesus’ teachings matter tremendously to Christians. But his death matters still more.

No doubt you knew that. The first thing anyone learns about Christianity is its symbol, the cross on which Jesus was executed. One of the cruellest forms of capital punishment that has ever been legal, those executed on the cross were called ‘crucified’ – a word which still has its shuddering power even today. Crucifixion was a death reserved for the lowest of the low: common thieves, runaway slaves, rebels, and lawbreakers. Yet this particular death was the ultimate goal of Jesus’ life.

Why? What’s it all about? For Christians, Jesus’ crucifixion strikes at the very root of all that is wrong with the world. To understand it, first we have to understand what Christians believe about that.

If you fall into a pit you can’t climb out of, then lack of information is not your problem. Nor does it matter how many other people are in the pit with you: nobody down there can pull you or themselves out.

Everyone agrees the world in its current state is, to put it mildly, less than ideal. Most put it down to a lack of education, or to the stubborn foolishness of a few isolated individuals.

If you believe that people behave badly because they are ill-informed, then you might think the solution is to teach people what is right. You will put great faith in education: give people the information they need and they will change their ways.

Alternatively, if you believe ‘other’ people are the problem, you can focus your attention on opposing them, imprisoning them, or stripping them of power somehow. But Christians believe that the root of the problem is far deeper, such that these efforts only scratch the surface and will never be effective in the long run.

Christians believe that the whole of humanity has been damaged, cut off from its relationship to what matters by a primordial catastrophe that we call ‘the Fall’. Human beings are not simply ignorant, and the problem does not lie in lack of information, or education. The problem lies in our will, the part of us that chooses what is wrong even when we know full-well that it is wrong. And the problem is not just some people ‘over there’, conveniently set apart from me. Every single human being has been impacted. Including you. And me. Every one of us is part of the problem, which is why no one of us, however smart or well-informed we are, can be the solution. If you fall into a pit you can’t climb out of, then lack of information is not your problem. Nor does it matter how many other people are in the pit with you: nobody down there can pull you or themselves out. You need someone outside the pit who can reach down and grab hold of you.

That is why Christianity is more than a moral programme for self-improvement, or a set of spiritual practices comparable to those of other religions. According to Christians, the human race does not need another set of rules about how to live, or a formula to cultivate mindfulness and inner peace. We need a saviour: someone who does not share our fallen condition, but who can reach down and lift us to safety.

How far down did Jesus have to go? All the way to the bottom, which means death. Even the worst kind of death.

How did Jesus’ death save us? Christians have various theories about that. You may have heard the most common which uses law court imagery: we were guilty and sentenced capital punishment, but Jesus was punished instead so we don’t have to. Some people love this theory and live by it; others find it morally problematic and offensive. But the point is not the theory: the point is the reality to which it points. One way or another, by dying Jesus reconnected us to God and restored the broken relationship.

But it’s stranger still than that, because Jesus’ death is not the end. It was only the preliminary to something far more wonderful and transformative, a sign of a promise beyond our wildest hopes. By dying, Jesus defeated death itself and came back to life. If Christmas makes no sense without the cross, then the cross makes no sense without the resurrection. But more on that in my next article.

It's our mistakes that make us human

What we learn distinguishes us from tech.

The distinction between technology and human beings has become blurry: AI seems to be able to listen, answer our questions, even respond to our feelings. It becomes increasingly easy to confuse machines with humans. In this situation, it is increasingly important to ask: What makes us human, in distinction from machines? There are many answers to this question, but for now I would like to focus on just one aspect of what I think is distinctively human: As human beings, we live and learn in time.

To be human means to be intrinsically temporal. We live in time and are oriented towards a future good. We are learning animals, and our learning is bound up with the taking of time. When we learn to know or to do something, we necessarily make mistakes, and we take practice. But keeping in view something we desire – a future good – we keep going.

Let’s take the example of language. We acquire language in community over time. Toddlers make all sorts of hilarious mistakes when they first try to talk, and it takes them a long time even to get single words right, let alone to try and form sentences. But they keep trying, and they eventually learn. The same goes with love: Knowing how to love our family or our neighbours near and far is not something we are good at instantly. It is not the sort of learning where you absorb a piece of information and then you ‘get’ it. No, we learn it over time, we imitate others, we practice and even when we have learned, in the abstract, what it is to be loving, we keep getting it wrong.

This, too, is part of what it means to be human: to make mistakes. Not the sort of mistakes machines make, when they classify some information wrongly, for instance, but the very human mistake of falling short of your own ideal. Of striving towards something you desire – happiness, in the broadest of terms – and yet falling short, in your actions, of that very goal. But there’s another very human thing right here: Human beings can also change. They – we – can have a change of heart, be transformed, and at some point in time, actually start to do the right thing – even against all the odds. Statistics of past behaviours, do not always correctly predict future outcomes. Part of being human means that we can be transformed.

Transformation sometimes comes suddenly, when an overwhelming, awe-inspiring experience changes somebody’s life as by a bolt of lightning. Much more commonly, though, such transformation takes time. Through taking up small practices, we can form new habits, gradually acquire virtue, and do the right thing more often than not. This is so human: We are anything but perfect. As Christians would say: We have a tendency to entangle ourselves in the mess of sin and guilt. But we also bear the image of the Holy One who made us, and by the grace and favour of that One, we are not forever stuck in the mess. We are redeemed: are given the strength to keep trying, despite the mistakes we make, and given the grace to acquire virtue and become better people over time. All of this to say that being human means to live in time, and to learn in time.

So, this is a real difference between human beings and machines: Human beings can, and do strive toward a future good.

Now compare this to the most complex of machines. We say that AI is able to “learn”. But what does it mean to learn, for AI? Machine learning is usually categorized into supervised learning, unsupervised and self-supervised learning. Supervised learning means that a model is trained for a specific task based on correctly labelled data. For instance, if a model is to predict whether a mammogram image contains a cancerous tumour, it is given many example images which are correctly classed as ‘contains cancer’ or ‘does not contain cancer’. That way, it is “taught” to recognise cancer in unlabelled mammograms. Unsupervised learning is different. Here, the system looks for patterns in the dataset it is given. It clusters and groups data without relying on predefined labels. Self-supervised learning uses both methods: Here, the system uses parts of the data itself as a kind of label – such as, for instance, predicting the upper half of an image from its lower half, or the next word in a given text. This is the predominant paradigm for how contemporary large-scale AI models “learn”.

In each case, AI’s learning is necessarily based on data sets. Learning happens with reference to pre-given data, and in that sense with reference to the past. It may look like such models can consider the future, and have future goals, but only insofar as they have picked up patterns in past data, which they use to predict future patterns – as if the future was nothing but a repetition of the past.

So this is a real difference between human beings and machines: Human beings can, and do strive toward a future good. Machines, by contrast, are always oriented towards the past of the data that was fed to them. Human beings are intrinsically temporal beings, whereas machines are defined by temporality only in a very limited sense: it takes time to upload data, and for the data to be processed, for instance. Time, for machines, is nothing but an extension of the past, whereas for human beings, it is an invitation to and the possibility for being transformed for the sake of a future good. We, human beings, are intrinsically temporal, living in time towards a future good – which machines do not.

In the face of new technologies we need a sharpened sense for the strange and awe-inspiring species that is the human race, and cultivate a new sense of wonder about humanity itself.
