What makes a genius different? I used to think a genius was someone who excelled at everything. With an IQ of around 150, whatever a genius does will be brilliant.  

In fact, most of the people we call geniuses excel at just one main thing, and it’s how they excel at it that makes them different. The German composer Johann Sebastian Bach (1685-1750) is a good example.  

In all sorts of ways, Bach was unexceptional. He didn’t lead an especially dramatic life. He was a working musician, with a stint as a court musician, and much longer stints as a church music director, latterly in Leipzig. In this respect, there were many like him at the time.  

He travelled very little. Socially, he was fairly conventional and conformist for his day, certainly not the sort to rock any political boats. He produced a huge quantity of music, certainly, but then so did many of his contemporaries. He was a Lutheran Christian. That is, he belonged to a wing of Christianity that followed the teachings of Martin Luther, the reformer who ignited the Protestant Reformation. And as a Luthern he was devout, but not exceptionally so for this time. He knew his Bible well, but so did hundreds of others in his day.  

He wasn’t a great writer of words. Like many musicians, he could be grumpy. He didn’t suffer fools gladly and was a hard taskmaster: he hated it when people tried to get out of doing hard work. He was not particularly well known during his lifetime, certainly not an international celebrity.  

In short, if we had met him socially, I doubt if we would have found it a memorable experience.   

And yet he changed the face of Western music, not simply “classical” music but every musical style from concert to folk, jazz to bebop, early pop (Lennon and McCartney were huge fans) to hard rock. Nothing was the same after Bach. Over the last 300 years, there is hardly a single musician who has not been impacted by him in one way or another, even if they might not know it. 

So in what does Bach excel? Why is he the most revered musician in history? People answer this in different ways, but for me, it comes down to something very simple: he turns the Christian life into sound to a degree no one before or after has come close to matching. This is not to say he is always preaching at you. He does proclaim, certainly, but the musical sounds he generates do not generally send “messages”. Rather, they help you feel what it’s like to live in this world—and understand the world—as a Christian.  

Take for example his mammoth masterpiece that tells the story of the suffering and death of Jesus as told by Matthew in the New Testament: the St Matthew Passion

 Right from the start, you do not simply hear about or observe the drama; you are taken inside it. In the opening scene Jesus trudges on the via dolorosa to his crucifixion. String basses and cellos pound away on one note in a faltering, dragging rhythm; other instruments tug away from each other in fierce dissonance. All this is in a dark minor key. We are made to feel in our bodies the slow, lumbering, doom-laden march of this man to his execution. But that is not all. On top of this, two choirs enter, singing to each other: the one asks puzzled questions (who is this?) and the other replies by unfolding the meaning of this strange procession: the condemned man is carrying the weight of the world’s human guilt. But that is not all. Over this, a third choir enters (usually a boy choir in today’s performances). These are the singers of the heavenly Jerusalem, far above the action, intoning an ancient hymn (“Lamb of God...”). Fittingly, they sing in a secure rhythm, and in a positive (major) key. Here God is winning back, healing his broken world, our world. Bach piles all these layers on top of each other so we hear them all at once—something only music can pull off (it is impossible with words alone). We trudge with Jesus as he identifies with us at our worst, yet at the same time we are surrounded by an eternal assurance that here God is doing his climactic work.  

Listen to St Matthew Passion

Another especially pointed example of Bach’s “inside” view comes when Bach tackles one the most famous scenes in Matthew’s story. Peter, supposedly Jesus’ most loyal follower, has just publicly denied he ever knew him. And this despite pledges of unswerving loyalty. He retches inside as his beloved leader is led away to his trial and death. A tenor soloist sings Matthew’s simple sentence: “And Peter went out and wept bitterly.” That is about as terse as you can get. But Bach strings these words out over a tortured, tormented melody—close to the sound of a person wailing with grief. When we reach the word “out” (as in “Peter went out”), Bach has the tenor sing a top B, the highest note he sings in the entire work. A musical “going out” is linked to a physical and metaphorical “going out”. And all this happens over the most anguished, dissonant, harsh harmony. It’s painful to listen to—which is, of course, the point. Again, Bach is not depicting something at a distance. He doesn’t even want us to feel sorry for Peter, for this is not about someone else. It’s about us. He wants us to us to feel something on the inside: that we have betrayed the One who more than anyone else has been prepared to die for us. 

Listen to Peter's story

Two glimpses of a Christian mind in action. But just as remarkable is what Bach can do without any words at all. He gave birth to hundreds of instrumental pieces, and he seems to have believed these were just as important as his vocal works. That’s because he believed musical notes—melodies, chords, motifs, riffs, harmonies—carried their own power to help us sense what it feels like to live in a world brought into being by the Christian God.    

From the most unpromising motifs, the most unremarkable clusters of notes, he can weave music of astounding richness. 

A lot of Bach’s music for instruments comes alive when heard in this light. It is as if we are being invited to listen to a cosmos in sound. A towering example is his famous Chaconne from the Partita in D minor for solo violin. Most scholars recognise that more than any other musician before or since, Bach knows how to get the most out of the least. From utterly unpromising motifs, unremarkable clusters of notes, he can weave sounds of astounding richness. In this piece he weaves fifteen minutes of music from a simple four-bar chord pattern, a seemingly endless series of variations of every mood and colour. The impression is of an infinity of possibilities, a boundless abundance. Even when he does eventually draw things to a close, as many scholars have noted, we are left with the impression this could have gone on ad infinitum

Listen to Chaconne, played by Itzhak Perlman

Very much the same applies to the even longer Goldberg Variations for keyboard, whose breathtaking overflow is evoked well in words from the distinguished Bach scholar, John Butt:  

“There is something utterly radical in the way that Bach’s uncompromising exploration of musical possibility opens up potentials that seem to multiply as soon as the music begins. By the joining up of the links in a seemingly closed universe of musical mechanism, a sense of infinity seems unwittingly to be evoked.” 

Bach is, in effect, giving us a musical imagination of something basic to Christian faith: that we live in a world in which the Creator God is constantly at work, drawing a potentially infinite number of options out of even the most unpromising material: which of course, we should take to include ourselves—ordinary, frail, and stumbling human beings.    

Not only that, Bach invites us to hear the interweaving of radical consistency and radical openness. Listen to a minute or two of the Chaconne and press pause at almost any point; it’s very hard to predict what will happen next, even if you know the style well. And yet what does happen makes perfect sense. In other words, it sounds as if it’s being improvised. This is why jazz musicians are so intrigued by Bach’s music. There is nothing deterministic about it: we are not inside a machine, or something that must unfold in the way it does. And yet it is anything but arbitrary or absurd-sounding. Bach seems to have sensed what many contemporary physicists will confirm: we don’t live a fixed universe in which the future is simply the unwinding of the past, and yet the world has a regularity to it, a dependability—it makes sense. In Bach’s imagination—as in the Bible itself—God is not arbitrary or fickle. God is the improvisor, we might say: faithful and surprising at the same time. 

Finally, we mention one other striking feature of Bach’s sound world that is hard to miss: the way it can encompass extreme joy and extreme pain. Bach was no stranger to grief and death. Both his parents died before he was ten years old. He fathered twenty children, but seven of those died immediately after birth or in infancy. He was out of town when his first wife, Maria Barbara, died; he was never able to say his farewells.  

To hear Bach at his most dissonant, taking us to the very edge of coherence, listen to Variation 25 from the Goldberg Variations (used in Ingmar Bergman’s 1963 film “The Silence”).    

Listen to Variation 25

We do not know if he was thinking of the crucifixion of Jesus here (he openly tackled this theme elsewhere in music of extraordinary sorrow) but in this piece he plumbs such dark depths it is hard to believe there is no connection at all. For Lutherans, the death of Jesus was the very centre of God’s engagement with the world, the point where God identified most intensely with us in our darkest depths.  

And yet, even in pieces of this kind, as Bach scholars have often noted, and as we hinted above, Bach will often “overreach”, spill out of the parameters he sets for himself. The ecstasy you will hear in the "Et Resurrexit " of the Mass in B Minor is a good example: where the raising of the crucified Jesus from the dead is translated into music that might well be called hyper-energetic. Again, Bach doesn’t allow us to observe and contemplate things from a safe distance. He is trying to catch us up into a life that by its very nature is uncontainable. As with so much of Bach's music, dance is the fundamental dynamic here: it is hard to keep still when surrounded by the cascading momentum. With a twinkle in his eye, he adds an orchestral postlude that by the conventions of his time was wholly unnecessary, gratuitous, excessive—a fitting testimony to the superabundant character of what he believed happened on Easter Day. In the midst of a society surrounded by the brute physical reality of death, including the deaths of members of his own family, Bach carries us into an overspill of energy that pulls against the downward, contracting “running down” of the physical world, evoking a “running up”—in his imagination, the life of the resurrection body to come.

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.
