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.

What makes us human?

We've more in common with our ancient ancestors than we might like to think

I recently caught up on iPlayer with the excellent BBC series Human. In it, the paleoanthropologist Ella Al-Shamahi explores 300,000 years of human evolution over five beautifully shot, evocatively presented episodes. I was transfixed by the story of these ancient human societies - of Homo habilis; Homo erectus; the hobbit-like Homo floresiensis - and of the ways that paleoanthropologists and archaeologists study the multiple human species. They walk barefoot in deep pits with what look like tiny paint brushes to dust off their finds. They are endlessly patient, and delighted at tiny scraps that I would overlook as rubbish. They see in these fragments stories of ancient lives that lived, ate, loved and died so long ago.

Take a set of footsteps fossilised into the ground in White Sands, New Mexico, discernible through their impact and weight distribution. They are thought to be those of a woman walking at speed, probably, scholars think, carrying a child. Now and again these footsteps appear to stop and stand, and in-between the right and the left foot are a small set of footprints. The mother appears to have put down the child for a moment before picking him or her back up and starting again.

This was so familiar to me, a mother of four. It reminded me of all the times I’d carried toddlers around on my hip before giving up, plonking them on the floor and then switching sides. This very human urge to care for our children, and to get tired by them, echoed through time. Although luckily for me I did not have a giant sloth chasing me, as this ancient mother seems to have done.

But the flip side of the ability to love is the ability to also reject. And the series highlighted that this less pleasant human habit – the exclusion of others – appears to be an equally core part of our existence.

Al-Shamahi asks,

‘what must it have been like to have been a hybrid child... Did these children feel like they belonged or were they teased and ostracised?’

Behind her question is a sense of deep concern about the hybrid children’s welfare all those millenia ago.

Fast forward thousands of years. Most of us went to school and know what it feels like to either be different or see someone else who is different. Imagine if a modern-day Homo sapien/neanderthalensis hybrid turned up the local primary school, would it be okay? Unlikely. We don’t look after difference particularly well. The question Al-Shamahi posed seems pertinent today as well as in palaeoanthropology terms, what would it be like to grow up a hybrid? For us today the question is similar, how do we judge what is human? Is our human status founded in the horror and aversion to difference?

The drive to surround ourselves with similarity and force others to fit is sometimes called ‘the cult of normalcy’. This behaviour only tolerates people who look, act, and represent what is familiar to you. I experience this as a neurodivergent person struggling at times to feel ‘normal’. That is why the story of hybrid children is affectively impactful. Their struggle is easy to imagine, how do they fit in?. What makes them and us human?

The little story of a mother and a child being carried (minus the sloth part) is enchanting. Is it this love for children that makes the ancient people count as human? Is it the presence of a relationship and the assumed communication between individuals that makes them human?

The risk here is to say that all people who are in families, who are parents, are the prime example of humanity and that does not fit with many lives that we would want to count as human. Love may be essential, but it cannot be a prescriptive type or circumstance. Nevertheless, the allure of love and community is strong in Human and my response to it. That familiarity with the feeling of exclusion of the hybrid child and the story of the mother and child are common. They are experiences that we can relate to concerning community and care. The series shows these human species in relationship groups, with evidence of successful community and unsuccessful community (again a familiar trait). So far, that ability to love is also the same ability to reject, to cast out the hybrid or the different human. That is unsatisfactory as the trait of what is core to humans despite the likelihood of it being at the heart of the human story.

What, then of religion? These ancient peoples who lived before language and writing yet still worshipped – their practices evident from paintings found on the walls of caves. Is this what it means to be finally human? Was it, I thought, when they demonstrated language? Was it the early signs of religion and worship? Was it to do with thinking and rationalising, deciding upon a set of gods and the rules about them? However, this cannot be. For there are people today who do not speak through choice or disability. There are those who cannot demonstrate their ability to worship, for the same reasons. Rationalising cannot be the way in which we determine humanity, for then are children, or the intellectually disabled not human? If awareness of the sacred is what makes us human, then that limits those whose cognitive abilities are different.

Christians believe that what makes us human is the image of God in us. But what is that image? It is given to humans when God made them right at the beginning of things. It is the divine something that sets us apart from trees and plants, even animals. It is a quality that God gives to humans in the creative act of making them. It is not something that humans do for themselves but something they receive from God. Could it be applied to Neanderthals or early human species? I think so. Although these early species were very different in some respects to us, they had the features of humanity that count. They had relationships, the capacity to experience awe and wonder and they loved one another (like the mother and child). The image of God could be many things but one thing is certain, it a gift from God because of his love for humans. The need for love, community and worship that is in all of us points back to this. We love one another because we are first loved by God and that is what makes us human.
