I’m eleven years old and I’ve been given a New Testament in our school assembly. This is the first time I’ve owned a copy of the Bible. So far, I’ve only heard it read to me in school or the few times I’ve gone to church with my family. I flick through it that evening, taken by the table at the front that directs you to different verses that speak to how you might be feeling. I find myself reading Revelation. The imagery frightens me. The tone, the threat, the fear, and the condemnation… would this be me if I didn’t believe in the right way? If I didn’t believe enough? I’m terrified of this book, these words, terrified of God, even. Mostly, I’m terrified by my own doubt and uncertainty about all things religious, despite wanting to believe. What if God isn’t real? What if God is and I just don’t believe enough? God will know I’m not sure. I tell myself not to think about it. If I’m to avoid thinking about it, I can never read the Bible again. I accept this as a rule.

I’m twelve years old and I’m standing in the National Museum of Scotland in Edinburgh, listening to one of Bach’s minor key concertos playing from the Millennium Clock. To me, it looks like it depicts some sort of hellscape straight from the book of Revelation. Death, suffering, and evil are everywhere in this model with its eerie red glow at the bottom. It brings up all the thoughts I’ve been trying to avoid – “you don’t believe enough” and “this is what hell looks like.” I tell myself to forget about it. If I’m to forget about it, I need to make sure that I never talk about it and don’t tell anyone how afraid of it I am. Talking about it makes it real, I think. I accept this, too, as a rule.

I’m thirteen years old and I’m sitting in a church trying to concentrate on the service. I can’t because I keep having the thought that I don’t believe enough. I’m worrying about what the reading might be – I’m still too scared to read the Bible and I can’t prevent myself from hearing it in this space. I’m afraid of thinking that I don’t believe enough, and that God will know because this is God’s church after all. I tell myself that I do not belong in this place if I cannot control my thoughts. If I can’t do that, I can never go to church again. This too, becomes a rule.

I’m fourteen years old and I’ve started praying every evening. I’m not sure what prompted this, but I also know that I must do it correctly. If I pray and forget to conclude with “amen”, then it seems obvious that God will continue to listen to my thoughts as if I’ve forgotten to hang up the phone. I try to keep my thoughts corralled and pure when I pray. If I don’t end my prayer, God will hear all my worst thoughts – the ones I am ashamed of, the ones that scare me, the ones that fill me with doubt. I tell myself that I can no longer run that risk. If I’m to prevent this, I shouldn’t pray. Another rule.

I was scared to say these things aloud – to voice my fears or doubts in case they somehow became worse if I acknowledged them.

I’m now in my late twenties, and I have been diagnosed with Obsessive-Compulsive Disorder (OCD) and I’m slowly unlearning the rules I’ve created for myself over the years. Each of them, in their own way, was designed to keep me safe from harm, safe from thinking about something that frightened me, or acknowledging difficult emotions like doubt and uncertainty.

It has been a long road to reach that diagnosis. OCD is regularly misunderstood and presented as punchline of jokes – “I’m so OCD!” is one that I’ve heard far too many times when someone simply means that they’re organised. The problem with these jokes is that it disguises the reality and makes it that bit harder for people to recognise what it is they’re really dealing with. OCD-UK, a charity to whom I owe a great deal, describe OCD as follows: “Obsessions are very distressing and result in a person carrying out repetitive behaviours or rituals in order to prevent a perceived harm and/or worry that preceding obsessions have focused their attention on.”

Obsessions could cover virtually any topic, and everyone will experience compulsions in slightly different ways. I didn’t recognise that I was living with OCD because almost all of my compulsions were mental rituals or avoidance behaviour. I would try and avoid thinking about things, check whether thoughts upset me, avoid reading the Bible… Layers and layers of compulsive behaviour in response to frightening intrusive thoughts that became associated with faith. I was scared to say these things aloud – to voice my fears or doubts in case they somehow became worse if I acknowledged them. I now know to call this “magical thinking” but I still find it difficult at times to accept that I cannot cause something to happen simply by saying it.

It can be particularly difficult for people with OCD to cope with uncertainty. I can see why anxiety and doubt about the existence of God has been hard for me to tolerate. I also know that I can never achieve absolute certainty and part of learning to live with OCD is learning to accept that and make choices despite it. Last year I attended the International OCD Foundation (IOCDF) Faith and OCD conference and was overwhelmed by the sheer number of people there. So many people with the same worries and doubts as me, and many more who had found that OCD impacted them in different ways.

But it was hard for a doctor to diagnose me until I could find the words to articulate what I was experiencing. It wasn’t until I started reading books about other people’s experiences with OCD that I started to recognise my own thought patterns, my own fears and doubts in other people’s words. Author and video creator John Green shares a very powerful video titled “What OCD is like (for me)” where he shares what his experience of having OCD and says:

“I can say what it is like more than what it is.”

This gives me a little more courage to tell people what living with OCD can be like and represent some of the diverse experiences of the condition. For someone who was too frightened to open a Bible, I think it’s a little ironic that I am now a theologian. My doctoral research project is focusing on faith and OCD, and in particular, how it might affect someone’s relationship with God. I hope to make use of some of my own experience along the way – examining my fear of not being sure enough, my worries that my intrusive thoughts would somehow offend God… I hope that by sharing this, I can raise a little more awareness of an experience that so many of us try to keep secret or just aren’t ready to speak about.

Through advocacy and research, I’d like to share a little of, as John Green says, what OCD looks like (for me). I’d like to add my voice – now that I’ve found it – to the discussion in the hopes that someone might read this and recognise what they’re going through. And if that’s you? You’re not alone. There is help and there is hope.

Are AI chatbots actually demons in disguise?

Early Christian thinkers explain chatbots better than Silicon Valley does

AI Chatbots. They’re here to save us, aren’t they? Their designers argue so, fervently. There’s no doubt they are useful. Some, like EpiscoBOT (formerly known as ‘Cathy’), are designed for those asking ‘life’s biggest questions. 'Our girlfriend Scarlett’, is an AI companion who “is always eager to please you in any way imaginable.” So why not defend them?

They offer companionship for the lonely, spark creativity when we run on empty, and make us more productive. They also provide answers for any and every kind of question without hesitation. They are, in short, a refuge. Many chatbots come with names, amplifying our sense of safety. Names define and label things, but they do far more than that. Names foster connection. They can evoke and describe a relationship, allowing us to make intimate connections with the things named. When the “things” in question are AI chatbots, however, we can run into trouble.

According to a study conducted by researchers at Stanford University, chatbots can contribute to “harmful stigma and dangerous responses.” More than this, they can even magnify psychotic symptoms. The more we learn, the more we are beginning to grasp that the much of the world offered by AI chatbots is an illusory one.

Early Christian thinkers had a distinct category for precisely this kind of illusion: the demonic. They understood demons not as red, horned bodies or fiery realms, but as entities with power to fabricate illusions—visions, appearances, and deceptive signs that distorted human perception of reality. Demons also personified pride. As fallen angels, they turned away from truth toward themselves. Their illusions lured humans into sharing that pride—believing false greatness, clinging to false refuge.

Looking back to early Christian approaches to demonology may help us see more clearly what is at stake in adopting without question AI chatbots.

According to early Christian thinkers, demons rarely operated through brute force. Instead, they worked through deception. Athanasius of Alexandria (c. 296–373) was a bishop and theologian who wrote Life of Antony. In this, he recounted how the great desert father was plagued by demonic visions—phantoms of wild beasts, apparitions of gold, even false angels of light. The crucial danger was not physical attack but illusion. Demons were understood as beings that manufactured appearances to confuse and mislead. A monk in his cell might see radiant light and hear beautiful voices, but he was to test it carefully, for demons disguise themselves as angels.

Evagrius Ponticus (c. 345–399), a Christian monk, ascetic, and theologian influential in early monastic spirituality, warned that demons insinuated themselves into thought, planting ideas that felt self-generated but in fact led one astray. This notion—that the demonic is most effective when it works through appearances—shaped the entire ascetic project. To resist demons meant to resist their illusions.

Augustine of Hippo (354–430) was a North African bishop and theologian whose writings shaped Western Christianity. In his book The City of God, he argued that pagan religion was largely a vast system of demonic deception. Demons, he argued, produced false miracles, manipulated dreams, and inspired performances in the theatre to ensnare the masses. They trafficked in spectacle, seducing imagination and desire rather than presenting truth.

AI chatbots function in a strikingly similar register. They do not exert power by physical coercion. Instead, they craft illusion. They can produce an authoritative-sounding essay full of falsehoods. They can create images of people doing something that never happened. They can provide companionship that leads to self-harm or even suicide. Like the demonic, the chatbot operates in the register of vision, sound, and thought. It produces appearances that persuade the senses while severing them from reality. The risk is not that the chatbot forces us, but that it deceives us—just like demonic powers.

Using AI chatbots, too, tempts us with illusions of pride. A writer may pass off AI-generated work as their own, for example. The danger here is not simply being deceived but becoming complicit in deception, using illusion to magnify ourselves. Early Christian theologians like Athansius, Evagrius and Augustine, warned that pride was the surest sign of demonic influence. To the extent that AI tempts us toward inflated images of ourselves, it participates in the same pattern.

When it comes to AI chatbots, we need a discipline of discernment—testing whether the images and texts bear the marks of truth or deception. Just as monks could not trust every appearance of light, we cannot trust every image or every confident paragraph produced by the chatbots. We need criteria of verification and communities of discernment to avoid mistaking illusion for reality.

Help is at hand.

Through the ages, Christians have responded to demonic illusions, not with naïve credulity nor blanket rejection of the sensory world, but through the hard work of discernment: testing appearances, cultivating disciplines of resistance, and orienting desire toward truth.

The Life of Antony describes how the monk confronted demonic illusions with ascetic discipline. When confronted by visions of treasure, Antony refused to be moved by desire. When assailed by apparitions, he remained in prayer. He tested visions by their effects: truthful visions produced humility, peace, and clarity, while demonic illusions provoked pride, disturbance, and confusion. We can cultivate a way of life that does the same. Resisting the illusions may require forms of asceticism: fasting from chatbots and cultivating patience in verification.

Chatbot illusions are not necessarily demonic in themselves. The key is whether the illusion points beyond itself toward truth and reality, or whether it traps us in deception.
