Why do films portray Christians as crazy?

Exploring why films often portray the god-fearing as ‘always so god-damn weird’, psychologist Roger Bretherton recalls a first divine experience.

We knew we were in trouble when he started quoting the Bible. If there is one rule we should all follow in a zombie apocalypse it is not to trust the isolated community of believers huddled around a Bible-quoting preacher. You know the plotline. The one that never occurs in Star Trek: the crew of the USS Enterprise land on a paradise-like planet only to discover that everything is exactly as it seems. No. The rules of genre television must be upheld. If it seems too good to be true, it probably is. 

This was the strong suspicion my eldest child and I immediately leapt to while watching season one, episode eight of HBO’s The Last of Us. If you haven’t seen it, it’s a zombie apocalypse drama, a bit like The Walking Dead, but with more giraffes and fewer zombies. Is it a virus? Is it radiation? No, it is a fungus that has zombified the masses. Starting with a few isolated infections here and there it rapidly mushroomed (I guess) to turn the placid citizens of the world into manic flesh-eaters. All I’m saying is keep applying the anti-fungal toenail cream, it may be the only thing standing between us and the collapse of civilisation as we know it.  

So, when episode eight opened with a previously unknown character quoting the Bible to a fearful flock hiding in a diner, we knew things weren’t going to turn out well. The signs were all there. He was almost definitely a paedophile, possibly a murderer, and very likely a cannibal. As it turned out we’d hit a perfect straight: three for three. He was all of them. I probably should have issued a spoiler warning for that one, but to be honest if you didn’t see it coming The Last of Us probably isn’t for you. You’d probably be happier watching something more sedate. Silent Witness anyone?  

Needless to say, the episode provoked no small amount of theological commentary in our household, mainly querying why it is that anyone exhibiting even a modicum of Christian belief in shows like this, almost always turns out to be completely unhinged. Why do the righteous always have something wrong with them? Why are the god-fearing always so god-damn weird?  

Pray and take the pills 

Just to be clear, I’m not a murderer, nor a paedophile, nor a cannibal (and I have no plans), but somehow the prejudice that Christians must be crazy has come to influence how I view my own spiritual history. I have inadvertently imbibed the simple naturalistic logic that if I am a Christian then there is something wrong with me. Some part of me shakes hands with Freud and retrospectively attributes my conversion to neurosis, a coping strategy, a crutch. The assumption that the only reason I would believe something so unusual, so out of step with the people I spend most of my time with, is that I am weird. Quietly, without realising it that is how I have come to view it - I need God because I am weak. 

Of course, religion can and often is used as a coping strategy. Leading psychologists of religion, like Kenneth Pargament, have made entire careers out of studying this phenomenon. For several decades, he and his collaborators have demonstrated pretty conclusively that people use religion and spirituality as potent sources of coping with the pain of life. From this perspective, religious conversion can be viewed as a transformation of significance. When the things we previously relied on to give us a sense of meaning and stability fail us, when our adjustment to life falls apart and cannot be put back together, we give up trying to conserve what was previously meaningful and instead take a transformative leap toward a new view of what matters to us. When the going gets tough, the tough get going. When the going gets too tough, some people turn to Jesus.  

But there are many ways we can use religion to cope, and over the years Pargament and his collaborators have identified a few of them. Some people defer everything to God, they cope by thinking God will do everything for them, they plead for Him to intervene. Others are self-reliant, they may believe in God, but they don’t expect much from Him; for them prayer is more like therapeutic meditation than anything medically effective. Others cope in a collaborative way. They don’t leave it all to God, nor do they think everything centres on them. They take responsibility for their lives, but view God as a companion, a collaborator, a conversation partner through all the vicissitudes of life.  

It probably comes as no surprise that in studies of religious people dealing with chronic illness, these styles of coping significantly predict prognosis over time. There are many ways it can help us, and some of them are more admirable and effective than others. Those who leave it all to God usually do worse, those who think it’s all down to them do better, and those who pray and take the pills do best. Coping with a painful and bewildering world is undoubtedly one of the benefits of religious belief. It’s one of the things it does for us, but it is not what religion is at core. It may be a function of belief but not its essence.  

That first intimation of divine presence... It was the teaser trailer of a movie I was yet to see. A tiny taster from an infinite menu. 

As a twelve-year old boy, lurking at the back of an old Methodist church, waiting in silence for the possibility of something sacred to be unconcealed, I was not the kind of child anyone at school would ever admire: lonely, bullied, ignored. Relegated to the corner of the playground reserved for the outcasts and untouchables, the overly sensitive gay kid, the boorish tractor enthusiast, and the Dungeons and Dragons players. When I revisit the moment of my first truly transcendent and mystical experience of God, it’s tempting to write it off as an imaginative invention designed to anaesthetise the pain of social exclusion. I needed it to be true, so I made it up.  

Yet there is more to it than that. That first intimation of divine presence was the beginning of a lifelong quest to experience more. It was the teaser trailer of a movie I was yet to see. A tiny taster from an infinite menu. And in the years that followed I pursued it. To begin with, that strange sense of presence was elusive. I couldn’t generate it under my own steam but ran across it every few months, in a small group, a church service, a prayer meeting, a piece of music. Over time the frequency increased, as I learned patterns of prayer and spiritual practice. Eventually, decades later, it stabilised into an almost daily occurrence. I discovered the western mystical tradition, a historical lineage that made sense of what I was sensing, and to which I could belong. I made myself at home with Augustine of Hippo, Julian of Norwich, Ignatius of Loyola, Teresa of Avila, John of the Cross, Thomas Merton. My new extended family was large and varied. They became my friends and spiritual guides. I had a history. 

When I think of the creatives I know, the artists, writers, actors, and musicians I have spent time with, I notice that for many of them their art is a response to the tragedy of life. But I rarely judge their work on the loneliness and pain that drives their compulsion to create. All too often it is the aching that lingers just under the surface of their work that makes it poignant and affecting. It is not just the beauty of what they create that moves me to tears, it’s the heartbreak out of which it is composed.  

My spiritual journey seems somewhat similar, a creative enterprise launched and sustained by a new insight into the nature of the world. Faith is more like a new way of seeing, than a new set of propositions to believe. If I’d been happy and fitted seamlessly into the fabric of social life, I doubt I’d have been open to the experience or able to recognise it when it occurred. But just as we might hesitate to reduce an artist’s work to little more than psychological self-help, I find myself increasingly reluctant to view my spiritual history as just an expression of my own neurosis. There is another way to tell the story, one that emphasises not so much the problems that drove me to God, but the presence that drew me to Him. There is more to the story than my own neediness and, in the final analysis, when the zombie apocalypse comes, at least I have retained sufficient sanity to avoid the guy with the Bible.

Ethics needs to catch-up with genetic innovation

Are we morally obliged to genetically edit?

It makes me feel very old when I realise that Louise Brown, the first baby to be born via in vitro fertilisation (IVF), will be 47 years old on July 25th this year. Since her birth in 1978, over 10 million IVF-conceived babies have been born worldwide, of whom about 400,000 have been in the UK. Over that period, success rates have increased such that in some clinics, about 50 per cent of IVF cycles lead to a live birth. At the same time, there have also been significant advances in genetics, genomics and stem cell biology all of which, in relation to human embryos, raise interesting and sometimes challenging ethical issues. 

I start with a question: what is the ‘moral status’ of the early human embryo? Whether the embryo arises by normal fertilisation after sexual intercourse or by IVF, there is a phase of a few days during which the embryo is undergoing the earliest stages of development but has not yet implanted into the wall of the uterus; the prospective mother is not yet pregnant. In UK law, based on the Human Fertilisation and Embryology Act (1990), these early embryos are not regarded as human persons but nevertheless should be treated with some respect. Nevertheless, there are some who oppose this view and believe that from the ‘moment of conception’ (there actually isn’t such a thing – fertilisation takes several hours) embryos should be treated as persons. In ‘conventional’ IVF this debate is especially relevant to the spare embryos that are generated during each IVF cycle and which are stored, deep-frozen, in increasing numbers for possible use in the future.  

A further dimension was added to this area of debate when it became possible to test IVF embryos for the presence of genetic mutations that cause disease. This process is called pre-implantation genetic diagnosis and enables prospective parents who are at known risk of passing on a deleterious mutation to avoid having a child who possesses that mutation. But what about the embryos that are rejected? They are usually discarded or destroyed but some are used in research. However, those who hold a very conservative view of the status of the early embryo will ask what right we have to discard/destroy an embryo because it has the ‘wrong genes’. And even for the many who hold a less conservative view, there are still several questions which remain, including ‘which genetic variants we should be allowed to select against?; should we allow positive selection for genes known to promote health in some way?’; should we allow selection for non-therapeutic reasons, for example, sporting prowess?’ These questions will not go away and there are already indications that non-therapeutic selection is being offered in a small number of countries. 

Genetic modification 

This leads us on to think about altering human genes. Initially, the issue was genetic modification (GM) which in general involves adding genes. GM techniques have been used very successfully in curing several conditions, including congenital severe immune deficiency and as part of treatment programmes for certain very difficult childhood cancers. One key feature of these examples is that the genetic change is not passed on to the next generation – it just involves the body of someone who has already been born. Thus, we call them somatic genetic changes (from the Greek, sōmatikos, meaning ‘of the body’).  

Genetic modification which is passed on to the next generation is called germline GM which means that the genetic change must get into the ‘germ cells’, i.e., the sperm or egg. Currently, the only feasible way of doing this is to carry out the genetic modification on the very early embryo. At present however, with just one very specific exception, GM of human embryos is forbidden in all the countries where it would be possible to do it. There is firstly the question of deciding whether it is right to change the genetic makeup of a future human being in such a way that the change is passed to succeeding generations. Secondly, there are concerns about the long-term safety of the procedure. Although it would involve adding specific genes with known effects, the complexity of genetic regulation and gene interactions during human development means that scientist are concerned about the risks of unforeseen effects. And thirdly, germline GM emphasises dramatically the possibility of using GM for enhancement rather than for medical reasons.  

Genome editing 

This leads us to think about genome editing. In 2011, it was shown that a bacterial system which edits the genomes of invading viruses could also work in other organisms This opened up a large array of applications in research, agriculture and medicine. However, the ethical issues raised by genome editing are, in essence, the same as raised by GM and so there is still a universal prohibition of using the technique with human embryos: germline genome editing is forbidden. Despite this, a Chinese medical scientist, He Jiankui, announced in 2018 that he had edited the genomes of several embryos, making them resistant to HIV; two babies with edited genomes had already been born while several more were on the way. The announcement caused outrage across the world, including in China itself. He Jiankui was removed from his job and then, after a trial, was imprisoned for three years; his two colleagues who collaborated in this work received shorter sentences. 

At present the universal prohibition of human germline genome editing remains in place. However, the discussion has been re-opened in a paper by an Anglo-Australian group.  They suggest that we need to develop heritable (i.e. germline) polygenic genome editing in order to reduce significantly an individual's risk of developing degenerative diseases. These includecoronary artery disease, Alzheimer’s disease, major depressive disorder, diabetes and schizophrenia. I note in passing that one of the authors is Julian Savulescu at Oxford who is already well-known for his view that parents who are able to do so, are ‘morally obliged’ to seek to have genetically enhanced children, whether by PGD, GM or genome editing. The use of polygenic editing, which would, in all likelihood, be available only to the (wealthy) few, fits in well with his overall ethical position. Needless to say, the paper, published in the prestigious journal Nature, attracted a lot of attention in the world of medical genetics. It was not however, universally welcomed – far from it. Another international group of medical scientists and ethicists has stated that ‘Human embryo editing against disease is unsafe and unproven …’ and even go as far as to suggest that the technology is ‘… going to be taken up by people who are pushing a eugenics agenda …’ remain very pertinent. 

Harder still and harder 

I have no doubt that amongst different reader there will be a range of opinions about the topics discussed so far. For anyone who is Christian (or indeed an adherent of almost any religious faith), one of the difficulties is that modern science, technology and medicine have thrown up ethical questions that could not have even been dreamed of by the writers of the Bible (or of other religious texts). We just have to use our wisdom, knowledge and general moral compass (and for some, prayer) to try to reach a decision. And if what I have already written makes that difficult, some recent developments multiply that difficulty still more.  

In the early years of this century, scientists developed methods of transforming a range of human cells into ‘pluripotent’ stem cells, i.e., cells capable of growing into a wide range of cell types. It also became possible to get both induced stem cells and natural stem cells to develop into functional differentiated cells corresponding to specific body tissues. This has huge potential for repairing damaged organs. However, other applications are potentially much more controversial. In 2023, Cambridge scientists reported that they had used stem cells to create synthetic mouse embryos which progressed at least as far as brain and heart formation within the normal pattern of mouse embryo development. 

At about the same time, the Cambridge group used individual human embryonic stem cells (from the blastocyst stage of embryonic development), to ‘grow’ early human embryos in the lab. There is no intention to use these embryos to start a pregnancy – indeed, it would be illegal to do so – but instead to study a period of embryo development which is not permitted with ‘real’ human embryos (research must not continue past 14 days of development). But how should we regard synthetic embryos? What is their moral status? For those who hold a conservative view of the normal human embryo (see earlier), should we regard these synthetic embryos as persons? Neither does the law help us. The legal frameworks covering in vitro fertilisation and early embryos (Human Fertilisation and Embryology Acts, 1990, 2008) do not cover artificial embryos – they were unknown at the times the legislation was drawn up. Indeed, synthetic embryos/embryo models are, in law, not actually embryos, however much they look like/behave like early embryos. Earlier this month, the Human Fertilisation and Embryology Authority (HFEA) discussed these developments with a view to recommending new legislation, but this will not dispel an unease felt by some people, including the science correspondent of The Daily Telegraph, who wrote that this research is irresponsible.  

But there is more. In addition to synthetic embryos, the HFEA also discussed, the possible use of gametes – eggs and sperm – grown from somatic stem cells (e.g., from skin) in the lab. Some authors have suggested that the production of gametes in vitro is the ‘Holy Grail’ of fertility research. I am not so sure about that but it is clear that a lot of effort is going into this research. Success so far is limited to the birth of several baby mice, ‘conceived’ via lab-grown eggs and normal sperm. Nevertheless, it is predicted that lab-grown human eggs and sperm will be available within a decade. Indeed, several clinicians have suggested that these ‘IVGs’ (in vitro gametes) seem destined to become “a routine part of clinical practice”.  

The lab-grown gametes would be used in otherwise normal IVF procedures, the only novelty being the ‘history’ of the eggs and/or sperm. Clinicians have suggested that this could help couples in which one or both were unable to produce the relevant gamete, but who still wanted to have children. In this application, the use of IVGs poses no new ethical questions although we may be concerned about the possibility of the gametes carrying new genetic mutations. However, some of the more wide-ranging scenarios do at the least make us to stop and think. For example, it would be possible for a same-sex couple to have a child with both of them being a genetic parent (obviously for males, this would also involve a surrogate mother). More extremely, a person could have a child of which he or she was actually, in strictly genetic terms, both the ‘father’ and the ‘mother’. What are we to make of this? Where are our limits?  

Dr Christopher Wild, former director of International Agency for Research on Cancer, explores in depth many of the developments and issue I outlined above. His article on why a theology of embryos is needed, is clear, well-written, helpful and thought-provoking.
