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.

This pub chat brought us to tears

In the debris of the Enlightenment there’s a rising warmth to the mystical.
Four people sit round a pub table, some look animated, others pensive.

I recently found myself sitting in an Oxford pub, crying with a man I barely know. And I wanted to tell you about it.  

How did we, two almost-strangers, find ourselves crying opposite each other?  

Well…  

Oh, gosh. How do I say this? We were crying because we were talking about Jesus. 

We’d both been spending the week at a gathering of academics in Oxford and one sunny afternoon, we, along with the other attendees, had wandered to one of Oxford’s effortlessly enchanting pubs. We ordered a couple of their finest IPAs and found ourselves perched next to each other. I quickly gauged that this guy doesn’t dabble in small talk, so, right there - sat in battered leather armchairs and surrounded by people - we spoke to each other about Jesus. Not in any kind of academic or philosophic manner; we just sort of shared what we think of him, what we feel about him, what we wonder about him.  

Ten minutes later, we had demonstrably leaky eyes.  

You see, my comrade in tears and I, we’re both Christians. Over the past two-thousand-ish years, that term has come to mean a number of things – it’s become a weighted word. But what I mean when I say that we’re both Christians, is that we love Jesus.  

That’s so weird to say, isn’t it? I’m resisting the urge to polish that definition up, to mop up the whimsy and make it more palatable for you. My instinct is to reach for an academic reasoning, a profound way to make what I just said sound less weird. But I’m going to resist. I’m just going to let that seemingly absurd truth blow in the wind.  

Can I let you in on something, though? Something a little vulnerable? I love Jesus, but I find him hard to talk to you about. One of two things tends to happen when I try, I get emotional, or I get embarrassed. Neither feels helpful. 

Let’s start with the embarrassment, because it’s easier to explain.  

We live in the debris of the Enlightenment. We’re materialists, rationalists, all that we see is all that there is-ists. We want certainty, we want prove-ability, we want to stand upon the solid ground of reason. We’ve spent the last century or two valuing cold, hard, facts – not warm, soft, inklings. We’ve repeatedly traded mystery for mastery.  And, because of all those things, we’ve ushered in secularism. That’s what we call ourselves, isn’t it? Secular? Those who have outgrown their need of a cosmic saviour, those who have finally burst free of the God delusion.  

This story, this event, it teaches me that everything can be mended, including me. 

This is my context as much as it is yours, and so, with all of that swirling around me – with secularism acting as the societal stage upon which I stand - my belief in Jesus is odd. I have spent my life feeling deeply unintelligent for believing that Jesus was all that he said he was, I can’t deny that. Secular culture has often had me feeling as though I’ve pulled up a chair, ready and excited to play the game of life, only to find that I hold an old set of instructions. Secularism screams at me, points at me, makes me feel as though I’m wearing an outfit that went out of fashion two seasons ago. And so, much to my shame, I get embarrassed. I play its game, a game I wasn’t designed to play, and I lose.  

And then there’s the specificity of Jesus, right? 

Even in the corners of culture where secularism is losing its grip and there’s a rising warmth to the transcendent, mystical, unexplainable things – there’s still a guard up when it comes to religion. In many cases, rightly so. People tend to feel more comfortable in the ‘spiritual, not religious’ camp. There’s something self-preserving about allusivity, isn’t there? Saying that I believe in Jesus strips me of that luxury – my association with him means that I’m also associated with two billion other people, and that can be disconcerting. It means I have little control over how I’m perceived by you, nor how I’m represented by them. It also means that my experiential spirituality is housed within a specific story, a framework, a tradition – I don’t get to pick and choose. It’s an all-in kind of thing.   

So, every time someone who doesn’t know Jesus wants to talk to me about him – someone like you, perhaps - all of the above does its best to shut me up. It mostly wins and I mostly fail you. If – on occasion – I am able to rip the tape of self-consciousness from my mouth, I get frustratingly emotional. And that reaction is slightly harder to explain.

I don’t interact with Jesus as a metaphor, an archetype, or a symbol. You may think me delusional, but I’ve decided to take him at his word, to live as if he was everything that he said he was – fully God, fully human, the whole she-bang. And I take the same approach to Easter – the festival that celebrates the thing I believe to be the truest – Jesus’ resurrection. His death and subsequent un-death, what T.S. Eliot calls: ‘the still point of the turning world’. What Dr Martin Shaw regards as ‘the most extraordinary act of love, so catastrophic in its beauty, we’re still in shock two thousand years later’. 

The realness of it all moves me. It, just as Martin has diagnosed, shocks me. This story, this event, it teaches me that everything can be mended, including me. It brushes against my deepest longings, it silences my loudest fears. And Jesus, the God-Man at the centre of it all? I feel the truth of him in my bones, his love courses through my veins, his friendship makes my eyes sting.  

I feel silly saying all of that – knowing how such sentiments have no home in the secular world we’ve built up around ourselves. And so, I feel paralysed by the need to boil it all down to ‘five facts that prove the resurrection happened’. But I just can’t seem to master it.  

Instead, I wonder if it’s alright that the truth of the event is found in two near strangers inexplicably crying in a pub. Two near strangers being unspeakably moved by the real-ness, the here-ness of a man who was executed two-thousand years ago. Two near-strangers who – despite it going against their (or, at least, my) self-aware sensibilities - were forced to accept that their tears picked up where their words had left off.  

Is that kind of proof acceptable to you? After-all, I’ve never known of someone to weep over a good metaphor, an intelligent myth, or a profound philosophy.  

I’m not opposed to placing the claims of Christianity under the microscope, indeed, I do it myself (when you’re not around, obviously). I’m simply opposed to it being the only means by which we can assess its truth. Afterall, I’m never more certain of its truth than when the only thing I have to show for it is an embarrassing display of tears.
