Understanding the power of blood

From hospitals to hymn books, it's significant for a reason.

With one billion molecules of oxygen packed into each of your 30 trillion red blood cells, blood is sometimes known as the red river of life. Countless lives have been saved through blood transfusion, but why, throughout history, across continents and cultures, has there been a special interest in the blood of one man crucified 2,000 years ago, believing it alone to have “wonder-working power”?  

Whether you are a newborn baby with half a pint of blood, or an adult with nearer nine pints, “what is certain is that you are suffused with the stuff”, writes author Bill Bryson in his book, The Body.  

Once thought to ebb and flow in waves like the sea, from the liver to other organs, having been heated in the heart, blood in fact flows in a network of vessels measuring some 60,000 miles, with the heart acting as pump, not heater. Cleverly conserved through a complex system of blood-clotting in the case of injury, blood is a precious resource that needs replacing if lost in large amounts. Victims of road traffic accidents can require up to fifty units of blood; significant amounts are needed for organ transplantation, severe burns or heart surgery. 

The first human blood transfusion in Britain, using blood from a lamb, was performed by Dr Richard Lower in 1667, given not to replace blood loss but to change character: could the old be made young, the shy be made sociable through blood transfusion? Apparently not.  

Safe transfusion awaited the discovery of blood types by Dr Karl Landsteiner in the early 20th century. Today, NHS Blood and Transplant deliver 1.4 million units of red cells to 260 hospitals each year for transfusion; about 85 million units are transfused worldwide, given to replace blood loss after accident, surgery, ulcer, ectopic pregnancy or for anaemia in cancer. Also used to boost blood cell numbers in malaria, sepsis, HIV, leukaemia and sickle cell anaemia, blood transfusion is now amazingly safe. Fatal reactions are extremely rare, “occurring only in one out of nearly two million transfusions”, writes physician Dr Seth Lotterman. “For comparison, the lifetime odds of dying from a lightning strike are about 1 in 161,000,” he adds. The risk of HIV infection has dropped dramatically, to less than one in seven million. 

History tells though of the danger of transmitting disease from the blood donor during transfusion. The World Health Organization recognises risk of infection with HIV, hepatitis, syphilis, malaria, and Chagas disease. The Contaminated Blood Scandal saw an estimated 30,000 people in the UK given blood transfusions and blood products infected with hepatitis C, hepatitis B and HIV. More than 3,000 people died as a result, and thousands more live with on-going health complications. For my final Christmas article for Readers Digest, I wrote on Stephen Christmas, a tireless campaigner for blood safety who lived with haemophilia and died in 1993, having contracted HIV through contaminated blood. 

I was a blood donor. However, I am now unable to donate blood or organs for the rest of my life since there is a possibility that my blood is ‘stained’, possibly with prion disease, after adopting embryos. The Blood Transfusion Service will not accept donations from women who have had various fertility treatments. 

And there’s another uncomfortable truth about blood donation – the NHS does not have enough blood, organs, tissues, platelets, plasma or stem cells to treat everyone who needs it. As a nurse, I remember caring for a man dying of liver cancer. Suffering from sudden, massive melaena (blood loss in black, tarry stools as a result of internal bleeding), he received emergency blood transfusion, with bag after bag of blood being infused, until the consultant called for the treatment to stop, because the bleed was too big – and blood supplies too scarce.  

Struggling to accept the stark reality of stained blood and dangerous shortages, I kept coming back to an old Sunday School song about blood, where absolute abundance and ultimate cleansing are instead promised. 

There is a fountain filled with blood 
   Drawn from Immanuel’s veins; 
And sinners, plunged beneath that flood, 
   Lose all their guilty stains. 

Gruesome and graphic in its imagery, but full of deeper meaning. And as a nurse, I’m accustomed to blood, sometimes lots of it. I’ve seen that man bleed out on the ward that night; I’ve attended a road accident, where a boy lost his leg – but not his life, because towels stemmed the massive flow of blood. I’ve raced a patient to the operating theatre after her aortic aneurysm burst within; I’ve stemmed arterial bleeding from the groin by applying prolonged pressure to the site punctured by a catheter during cardiac stenting. According to the World Health Organization, severe bleeding after childbirth is the leading cause of maternal mortality world-wide. Each year, about 14 million women experience postpartum haemorrhage resulting in about 70,000 maternal deaths globally.  

In the Bible, and in hymns of praise like this one, there is also no getting away from blood. “Like it or not, the Bible is a bloody book,” writes  Kyle Winkler. It runs through the book like a crimson thread. There’s a story of a woman bleeding for twelve years, until she touched the hem of Jesus’ garment and was healed.    

Elsewhere the Bible keeps returning to the idea of blood, shed in sacrifice, used to cleanse, save, and heal in a spiritual sense. In the Old Testament, animal blood was painted on doorposts at Passover as a sign of protection from judgment, and sprinkled ritually on the altar as a sacrifice for human sin, restoring relationship with God.  

On Good Friday, Jesus himself shed (and sweat) his blood, sacrificing his life on the cross to “wash our souls” once and for all. Millions of Christians across the world take a sip of communion wine each Sunday in commemoration of this act. It’s a beautiful gift, coming with a promise that the shed blood will “preserve thy body and soul unto everlasting life”, through the forgiveness of sins. It’s no wonder then that churches love to sing about this blood. “Would you be free from the burden of sin? There's pow'r in the blood, pow'r in the blood,” goes one hymn, while another simply says, “Your blood has washed away my sin, Jesus, thank you”.  

“God’s intention for blood isn’t gory—it’s beautiful! And I’m certainly not offended or scared by it,” writes Kyle. “Rather than question how little blood I can get by with, I’d rather stand under the cross to be covered in all that I can get!” Thank God for the fountain of forgiveness that flows from Good Friday.

Our social problems need theology, here’s why

Taking the god’s-eye view develops critical skills

At secondary school level, Religious Studies continues to attract strong numbers. On the surface, this looks like a healthy sign for the subject. Yet, critics argue that appearances can be deceiving: many faith-based schools make the subject compulsory, artificially pushing up participation. The result is a stark disconnect when students progress to higher education. Here interest appears to drop off sharply, and several universities have been forced to close their single-honours degrees in Theology and Religious Studies due to unsustainable student numbers. 

But this presents a misleading picture – even at tertiary level students are far more interested in Theology and Religious Studies than the statistics seem to suggest. While few undergraduates commit to a full degree in Theology, (in Scotland this is called Divinity) or Religious Studies, partly because career pathways outside of ordained ministry and teaching can seem unclear, many are eager to sample the subject alongside their main studies. This means that at the University of Aberdeen, the department of Divinity finds a different kind of relevance. Thanks to Aberdeen’s flexible degree structure, it is not unusual to find law, sociology, psychology, anthropology, and even physics students sitting in on our undergraduate modules. This interdisciplinary mix brings a distinctive energy to classroom discussions, as well as a few challenges… and challengers.  

Some students arrive never having opened a Bible, never having heard a word from the Qur’an, and never having engaged with any other religious text. Many are openly ambivalent about the existence of God, some downright hostile, and more than a few admit that they were drawn in by the promise of coursework-based assessment rather than traditional exams. Yet, once in the room, most engage with surprising enthusiasm, and even the challengers play a vital role.  

What emerges is a lively space where students approach theology less as a matter of personal faith and more as an intellectual exercise, grappling with life’s big questions, testing out ideas, and debating seriously with the prospect that God exists. Far from diminishing the subject, this shift gives the Divinity department a new role: not as a training ground for clergy, but as a forum for critical thinking across disciplines. 

In one of our courses for example, students are asked to debate this question: if a human chooses to go wild swimming in a crocodile’s natural habitat, does the crocodile have a right to kill and eat that human, as it would any other prey item that strayed into its path? Or, if a person with profound physical and intellectual disability is not able to live out many of the rights and responsibilities envisaged by the United Nations Convention on Human Rights, on what grounds are they still reckoned to be a human person? As we tease out the (multiple) possible answers to these questions, many of the turn out to be surprisingly theological. Whilst some students will work towards becoming better able to affirm and articulate their own atheism, others are surprised to discover that they have been living out a deistic morality all along; on the quiet, their internal moral compass believes in God. 

But my sense is that even if students don’t walk out with an easy A, they walk out with a set of skills that is, in the long run, far more valuable. 

Further to that, in an open letter the Theos think tank recently highlighted the role of theology in the ethical and cultural development of communities. They argue that theological study equips people to engage thoughtfully with different people groups and traditions, to develop skills in interfaith dialogue, and to promote communication across cultural barriers. Put simply: 

“In an increasingly polarised world, it helps us understand other points of view.” 

This insight is highly relevant to our students as they set out on varied career paths in an increasingly complex world. The skills honed in our Divinity classrooms – empathy, critical thinking, close observation, and clear writing – are both essential and transferable. Theology degrees do not lead only to ordination or teaching; they can open doors to careers in journalism, diplomacy, politics, community work, authorship, and screenwriting, among many others. As Professor Gordon Lynch, Professor of Religion, Society and Ethics at the University of Edinburgh, observed at a recent panel discussion: 

“It’s very difficult to think about a major geopolitical issue at the moment in which religion isn’t deeply implicated in some way.” 

The relevance of theological training extends far beyond traditional disciplines. For example, law students will need to recognise not only that a person with profound disability is a human person, but also to understand the deeper ethical and theological reasons why society judges this to be so. International Relations students will need to appreciate why resolving the Israel/Palestine conflict is not as simple as drawing lines on a map, but is rooted in long histories of faith, identity, and belonging – histories which will reach their influence far into the future as well as the present. Sports science and physiotherapy students will need to empathise with the human drive to become ever faster and stronger, while discerning when to help people recognise the limits before injury occurs. 

So, we gather all these students and more into our divinity courses, and work with them as they develop such skills. By discussing these matters as though God exists, in a space where there is unapologetic openness to confessional or deistic ways of looking at the world, students are freed to adopt a third-person standpoint, a “god’s-eye view” if you like, which allows them to critically examine both their own and other people’s perspectives. When this freedom becomes apparent, it is the challengers often find themselves the ones being challenged, and hostility soon morphs into vibrant dialogue. Also, for those who want “an easy A” it quickly becomes apparent that coursework-based assessment is in no way easier than traditional exams – if anything, it can be the opposite! Getting your ideas down on paper, coherently, and with relevant references to research from across disciplines is a sophisticated competency. But my sense is that even if students don’t walk out with an easy A, they walk out with a set of skills that is, in the long run, far more valuable.  

With an eye to business models and balance sheets, many universities don’t think they need their theology departments anymore, and with the current financial precarity faced by the higher education sector, on paper this may be true. But society is crying out for complex ways forwards with complex situations, and the problems of social division are becoming more apparent than ever. Whilst it is clear that fewer and fewer students are choosing to do whole theology degrees, it is also clear the world still needs theologians.
