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.

Why is it taking so long to find an Archbishop of Canterbury?

The Anglican tortoise and the Catholic hare.

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

It seems the Roman Catholics have put the Anglicans to shame by the speed with which they have managed to appoint a new Pope. Pope Francis died on Easter Monday, 21 April. Pope Leo was elected on the 8 May. Seventeen days. Pretty impressive. Very few large corporations would replace a CEO in that time, or nations elect a new leader.  

Justin Welby, however, resigned on the 12 November 2024. We won't know the name of his successor until the autumn, and that person won't start in place until the spring of 2026. Well over a year.  

The Church of England is playing the tortoise while the Roman Catholics are acting the hare. 

So why is it taking so long? Is this just fusty Anglican bureaucracy? A depressing instance of Anglicans taking ages over everything, whether sorting out our divisions over sexuality or choosing a new Archbishop? 

As always, there is more to this than meets the eye.  

The first thing to say is, of course, that events took everyone by surprise. Justin Welby would have had to retire before his 70th birthday in January 2026, and the assumption had been that he would announce the date at some point before then. A process was already in place to make the appointment so that a successor could be named before he departed and start soon after, as usually happens. No-one foresaw the events that led to Welby’s surprise resignation over his handling of the abuse committed by John Smyth, outlined in the Makin Review. In the usual course of things, there would have been a relatively smooth handover. What we have is unprecedented – a year with no Archbishop of Canterbury at all.  

There is, of course, the shambles at the Canterbury end, where the diocese has taken three abortive goes at electing their representatives for the body that makes the appointment, the Crown Nominations Commission. More on that here, but even that has not had a significant effect on the timetable, which is following its predicted course, despite bumps along the way. 

Even so, many will say, could the system not have been hurried up? Maybe so, and it might have been wise to find ways to hasten the process a little, but the more fundamental answer is that’s not the way the Church of England works and never has.  

The biggest reason is that the Church of England and the Roman Catholic churches have different understandings of what the Church is and how it is governed. In short, the Archbishop of Canterbury is not the Anglican equivalent of a Pope. 

Back in the days of the English Reformation, after Henry VIII’s ego-driven separation from Rome, which enabled him to divorce his wife who was unable to give him a male heir, and marry the younger and prettier Anne Boleyn, the English church found a kind of settlement under Queen Elizabeth I, several generations later. This proposed that the ‘Supreme Governor’ of the Church of England was not to be the Archbishop of Canterbury but the Monarch. It was a way of expressing the idea that the Church of England is the Church of the people of England. It was the people of England at prayer. ‘We hold,' said Richard Hooker, the great architect of this vision, ‘that… there is not any man of the Church of England but the same man is also a member of the commonwealth.’ 

If you are a citizen of England, you have a right to be also part of the Church of England – to have your children baptised (once the vicar is sure you know what you’re letting yourself and your child in for), your marriage solemnised, and your body buried in the national church. The Church - although in a local sense is gathered group of Christians who attend public worship - exists for the people of England, whether or not they go to church regularly or not. 

Because the Church of England is the church of the people of England, a much larger group of people need to be involved when an Archbishop of Canterbury is chosen. So far, there has been a wide period of consultation, involving the remarkable figure of 11,000 people who have given input – far more than most consultations of this kind. Moreover, the group that appoints the Archbishop is made up, not just of bishops, but lay people, priests, men, women, people representing the diocese of Canterbury, five representatives of the global Anglican Communion, others representing the national Church and so on.  

The Church of England in that sense, is no respecter of persons, and refuses to treat the Archbishop as a Pope or a CEO.

For Roman Catholics, the church centres much more around its bishops. So, when it comes to choosing their leader, it makes sense to simply put all the cardinals (the most senior figures in the Catholic Church) in a room until they come up with a name from among themselves. Anglicans have a much longer, messier, more democratic process. It is not an election by a majority vote from a small electorate quickly convened, choosing among themselves, but a process of listening to a wide range of voices, both inside and outside the church.  

Because he is not a pope, the Archbishop of Canterbury is in one sense, just another bishop (the next one may be a woman, but all Archbishops so far have been men). Yes of course, he’s an Archbishop, so higher profile than the others, but he is nonetheless a bishop who takes his place among the other bishops of the CofE. Archbishops of Canterbury are regarded with respect and honour by other CofE bishops and Archbishops around the worldwide Anglican Communion, as the (Arch)bishop of the first ‘Anglican’ church – Canterbury. Yet they have no legal jurisdiction at all outside England – or even outside their own Province of Canterbury in the southern half of England. He is not the ‘spiritual leader’ of Anglicans all over the world, like the Pope is for Roman Catholics.  

As such, to put it bluntly, his appointment must take its turn among all the others in the queue. The Crown Nominations Commission is made up of people for whom this is not their day job, who give their spare time to it, and who have a programme of episcopal appointments to be made - the next in the queue are St Edmundsbury & Ipswich and then Worcester.  Canterbury has to take its turn. To enable this one to jump the queue would be saying something that Anglicans have never said - that this role is much more important than any of the others and must be given special treatment. The Church of England in that sense, is no respecter of persons, and refuses to treat the Archbishop as a Pope or a CEO, without whom the church would fall apart. 

The reason the Church of England can survive without an Archbishop of Canterbury for a while, is because its life is not dependent on a central figure, a charismatic leader, or a head office which issues instructions for all the branches to obediently follow. That may work in McDonalds but doesn’t work in the Church of England. The life of the Church of England is in its parishes and dioceses, which carry on doing their thing, even when an Archbishop of Canterbury is not available.  

Of course, it might have been possible to speed it up a little. We have missed having an Archbishop speaking in to public life and providing a lead at the national level. But there are good reasons for taking time. And it’s not just inefficiency – it’s because the Church is made up of ordinary Christians, who all deserve a say – and that takes time.
