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.

The Rest is Luther

Did 'The Rest is History' get Luther right? Graham Tomlin gives his verdict

Graham Tomlin

Graham is the Director of the Centre for Cultural Witness and a former Bishop of Kensington.

Two podcast hosts in different rooms appear on a split screen talking to each other

Tom Holland and Dominic Sandbrook rank Luther's influence.

I have to confess, I don't listen to every episode of The Rest is History - does anyone do that with the astonishing volume of material they produce? Yet when I see something that interests me – 1970s Britain, the Lost Library of Alexandria, the Easter Rising of 1916, I’m in. So, when I saw they were doing a series on Martin Luther, I just had to listen.

With much of what they cover - take the Lost Library of Alexandria for example - I wouldn’t really know whether they were telling the truth or not, having a passing interest and only a vague knowledge of the topic. Yet this one was different, because, without wanting to blow any trumpets, I do know a fair bit about Luther. I’ve written a doctorate, a biography and a couple of other books on him, lectured on Luther at Oxford University for many years, and spent a lot of time in libraries, poring over his commentaries and treatises, wading my way through dense books by German scholars picking apart the most minute aspects of his theology.

Very often when you hear something on the TV or radio that you know something about, you realise the journalists are winging it. They get away with it because no-one knows any better. So, I wondered this time, would I see through the boys on the podcast, and realise they were winging it too?

They made the Reformation sound and feel the dramatic and earth-shaking movement that it was.

Well, my admiration for Dominic Sandbrook and Tom Holland went up massively. It was brilliant. I once asked Tom whether they had an army of researchers doing their work for them and he told me they didn’t - they read most of the stuff themselves. So, to have them do five episodes on a topic that is not necessarily their specialist subject and get pretty much all of the story not just right, but really interesting, is quite an achievement. They made the Reformation sound and feel the dramatic and earth-shaking movement that it was.

They normally recount history with a good dose of humour, drama and colour. That is taken for granted. They know how to tell a good story. However, they also really know their stuff. Tom led the way, and I must say, told the story with a level of detail, accuracy and sympathy that was quite remarkable. They clearly enjoyed it too – they loved his earthiness, his preoccupation with the devil and excrement that is so distinctively Luther.

Martin Luther, as they said at the end, was no saint. He was a man of extremes. He could inspire devoted loyalty from his friends, and fury from his enemies in equal measure. He was never dull. He always said his besetting sin was anger – he claimed to write best when he was furious. That explains the vituperative language, the skill at invective, his genius for insults. He said terrible things about the peasants and even worse things about the Jews. Yet he also launched a movement that brought fresh dignity and purpose to countless people across Europe and beyond – he can be said to have touched the lives of the one billion Protestants in the world today. He literally changed the world. And Tom and Dominic helped us understand why.

Definitely a nine out of ten.

But why not ten?

Well, I did have one small quibble. Luther was portrayed as someone who struggled to know that God loved him. So far, so good. His great breakthrough was described by the excellent Tom Holland as “a personal experience of God”, whereby Luther found “a feeling of being washed in the love of God.” Luther’s new discovery was that “If God loves you, you exist in a state of grace… which is a feeling that Christ is present in you, in your secretmost heart, and the certainty of that grace gives you a peace of conscience.”

Now there is something of that in Luther, and it was close, but it’s not quite the way he would have put it.

Luther is really not that interested in experiences of God. In fact, he distrusts them. in 1521, a group of prophets arrived in Wittenberg from a small town called Zwickau claiming experiences of God, but Luther was having none of it. He asked about their experience – but not whether they had experienced the love of God, but whether they had experienced his absence. Had they experienced what Luther called Anfechtung – the experience of feeling God is against you, when you struggle with temptation, are driven to despair, when God doesn’t answer your prayers, and when all you know is your own shame, sin, and disgrace? What do you do then?

And that’s why the Bible was important to him – as an existential anchor when the storms of life hit.

The reason he asked about this was that such experiences so often are the things that help bring faith to birth, because they press the question of who you listen to, or trust, in such times – your own feelings of inadequacy and shame? Or God’s word that tells you something different?

Luther found peace of conscience, not in a mystical experience of the love of God, but in hearing again and again the Word which God had spoken to the human race in Jesus Christ. Against all the odds, and despite his frequent experience of God’s absence rather than his presence, he recalled that God had sent his Son, as a pledge once and for all, that God’s heart was full of love and kindness. In sending Christ, God had given himself (or technical language, his ‘righteousness’) to us in Christ, and the only fitting response, was simply to believe and trust that this is true, whereby that ‘righteousness’ becomes ours, and we are, to use Luther's language, 'justified'. Christians are therefore, in Luther’s classic and paradoxical phrase, ‘both righteous and sinful’ at the same time.

This was indeed profoundly emotional for him. It brought a flood of joy and relief. Yet that joy was the result of faith in faith in the Word, which was the main thing. The emotions followed faith, not the other way round.

He once put it like this: “God achieves his purposes through suffering, pain and anxiety. Yet of course these are not the things in which you expect to find God. As a result, most people do not recognise this as God’s work, because they expect God only to be revealed in glory, grandeur and splendour. The way God works confounds human expectations and so, faith is needed to see past the appearance of things to their true reality.”

This was the doctrine of justification by faith – not trying to be extra religious or having ecstatic experiences of God but simply betting your life on the notion that Jesus is God’s great gift to the world, a gift that tells us he is, despite everything that may point in the other direction, full of love and goodness – and not just to the human race in general, but to you, to me. And that’s why the Bible was so important to Luther – as an existential anchor when the storms of life hit.

Tom and Dominic did a fantastic job in their series on Luther. I really recommend you listen to it – you won’t regret it. Only remember, Luther relied more on faith in the Word of God than the fleeting feelings of his heart:

“Faith is a living, bold trust in God’s grace, so certain of God’s favour that it would risk death a thousand times trusting in it. Such confidence and knowledge of God's grace makes you happy, joyful and bold.”
