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.

Whether it's AI or us, it's OK to be ignorant

Our search for answers begins by recognising that we don’t have them.

When was the last time you admitted you didn’t know something? I don’t say it as much as I ought to. I’ve certainly felt the consequences of admitting ignorance – of being ridiculed for being entirely unaware of a pop culture reference, of being found out that I wasn’t paying as close attention to what my partner was saying as she expected. In a hyper-connected age when the wealth of human knowledge is at our fingertips, ignorance can hardly be viewed as a virtue. 

A recent study on the development of artificial intelligence holds out more hope for the value of admitting our ignorance than we might have previously imagined. Despite wide-spread hype and fearmongering about the perils of AI, our current models are in many ways developed in similar ways to how an animal is trained. An AI system such as ChatGPT might have access to unimaginable amounts of information, but it requires training by humans on what information is valuable or not, whether it has appropriately understood the request it has received, and whether its answer is correct. The idea is that human feedback helps the AI to hone its model through positive feedback for correct answers, and negative feedback for incorrect answers, so that it keeps whatever method led to positive feedback and changes whatever method led to negative feedback. It really isn’t that far away from how animals are trained. 

However, a problem has emerged. AI systems have become adept at giving coherent and convincing sounding answers that are entirely incorrect. How has this happened? 

This is a tool; it is good at some tasks, and less good at others. And, like all tools, it does not have an intrinsic morality. 

In digging into the training method for AI, the researchers found that the humans training the AI flagged answers of “I don’t know” as unsatisfactory. On one level this makes sense. The whole purpose of these systems is to provide answers, after all. But rather than causing the AI to return and rethink its data, it instead developed increasingly convincing answers that were not true whatsoever, to the point where the human supervisors didn’t flag sufficiently convincing answers as wrong because they themselves didn’t realise that they were wrong. The result is that “the more difficult the question and the more advanced model you use, the more likely you are to get well-packaged, plausible nonsense as your answer.” 

Uncovering some of what is going on in AI systems dispels both the fervent hype that artificial intelligence might be our saviour, and the deep fear that it might be our societal downfall. This is a tool; it is good at some tasks, and less good at others. And, like all tools, it does not have an intrinsic morality. Whether it is used for good or ill depends on the approach of the humans that use it. 

But this study also uncovers our strained relationship with ignorance. Problems arise in the answers given by systems like ChatGPT because a convincing answer is valued more than admitting ignorance, even if the convincing answer is not at all correct. Because the AI has been trained to avoid admitting it doesn’t know something, all of its answers are less reliable, even the ones that are actually correct.  

This is not a problem limited to artificial intelligence. I had a friend who seemed incapable of admitting that he didn’t know something, and whenever he was corrected by someone else, he would make it sound like his first answer was actually the correct one, rather than whatever he had said. I don’t know how aware he was that he did this, but the result was that I didn’t particularly trust whatever he said to be correct. Paradoxically, had he admitted his ignorance more readily, I would have believed him to be less ignorant. 

It is strange that admitting ignorance is so avoided. After all, it is in many ways our default state. No one faults a baby or a child for not knowing things. If anything, we expect ignorance to be a fuel for curiosity. Our search for answers begins in the recognition that we don’t have them. And in an age where approximately 500 hours of video is uploaded to YouTube every minute, the sum of what we don’t know must by necessity be vastly greater than all that we do know. What any one of us can know is only a small fraction of all there is to know. 

Crucially, admitting we do not know everything is not the same as saying that we do not know anything

One of the gifts of Christian theology is an ability to recognize what it is that makes us human. One of these things is the fact that any created thing is, by definition, limited. God alone is the only one who can be described by the ‘omnis’. He is omnipotent, omnipresent, and omniscient. There is no limit to his power, and presence, and knowledge. The distinction between creator and creation means that created things have limits to their power, presence, and knowledge. We cannot do whatever we want. We cannot be everywhere at the same time. And we cannot know everything there is to be known.  

Projecting infinite knowledge is essentially claiming to be God. Admitting our ignorance is therefore merely recognizing our nature as created beings, acknowledging to one another that we are not God and therefore cannot know everything. But, crucially, admitting we do not know everything is not the same as saying that we do not know anything. Our God-given nature is one of discovery and learning. I sometimes like to imagine God’s delight in our discovery of some previously unknown facet of his creation, as he gets to share with us in all that he has made. Perhaps what really matters is what we do with our ignorance. Will we simply remain satisfied not to know, or will it turn us outwards to delight in the new things that lie behind every corner? 

For the developers of ChatGPT and the like, there is also a reminder here that we ought not to expect AI to take on the attributes of God. AI used well in the hands of humans may yet do extraordinary things for us, but it will not truly be able to do anything, be everywhere, or know everything. Perhaps if it was trained to say ‘I don’t know’ a little more, we might all learn a little more about the nature of the world God has made.
