Beyond cold certainties

The Creeds set out a vision of reality – a vision that cannot be proved to be true, but which was found to be true by a community of people.

“I believe.” For many, the opening words of the Christian Creeds are self-defeating. Why read any further, when all they offer is opinions, rather than certainties? Faith is just a lower form of knowledge – a kind of hesitant half-truth, which seems out of place in today’s more sophisticated world, informed by science and philosophy rather than outdated worldviews inherited from a credulous past. 

It’s a fair point. We cannot believe anything we like; there has to be reason to believe it, evidence in its support. For those wedded to a hard rationalism, we can only believe what can be proved to be true. Yet the problem is that the secure truths of logic and mathematics are existentially inadequate. We seem unable to escape the lure of “ultimate questions”, to use Karl Popper’s term for truths about meaning and value in life that frustratingly lie beyond the scope of science to confirm. 

We can prove shallow truths. Yet the truths that really matter to us seem to lie beyond rational confirmation.

When it comes to the really important things in life, we are confronted with a rationalist dilemma. We can prove shallow truths. Yet the truths that really matter to us seem to lie beyond rational confirmation, often leading us into vicious argumentative circles rather than offering clear and persuasive proof. Bertrand Russell made this point in his famous defence of philosophy: “To teach how to live without certainty, and yet without being paralyzed by hesitation, is perhaps the chief thing that philosophy, in our age, can still do for those who study it.” 

Albert Einstein was fond of using mental experiments to open up some fundamental scientific questions, finding that they combined imaginative reflection with rational analysis. Here is a useful mental experiment. Suppose we limit ourselves to a mental and imaginative world in which we only accept what can be proved to be true. What sort of world would that be? It would, obviously, be a world from which Christianity was absent. Yet, perhaps less obviously, it would be a world from which all beliefs – moral, political, social and religious – are excluded. It would be a world without moral values, which remain obstinately resistant to rational or scientific verification. My suggestion is that this mental experiment indicates that this world would be existentially, morally and personally uninhabitable. 

The human quest for wisdom, goodness and meaning takes us beyond the cold certainties of logic.

The opening words of the Creeds need to be seen in this context. The human quest for wisdom, goodness and meaning takes us beyond the cold certainties of logic into a world in which we believe or trust certain things to be true, life-changing and live-giving – but cannot prove them to be true. The Latin word credo – traditionally translated into English as “I believe” – is better rendered as “I trust,” invoking the world of relationships rather than mere beliefs. 

The Creeds set out a vision of reality – a vision that cannot be proved to be true, but which was found to be true by a community of people, who have passed down in the Creeds their collective witness to what they discovered. As C. S. Lewis remarked, “the one really adequate instrument for learning about God is the Christian community.” This vision is affirmed to be trustworthy – not merely something that is transformative and liberating, but something that can be lived, not merely thought.  

Getting the bigger picture 

Faith is thus not a half-hearted hope that there might be a God. For Christians, it is a broad recognition that we live in a world in which certainty is not possible, save in closed mental domains that have little relevance to the serious business of living well and authentically. It is about “getting” what things are all about in an epiphanic moment of putting everything together and seeing a bigger picture within which we realize we belong and can flourish. There are other big pictures, of course – but all of them lie beyond proof. In choosing any of these, we are making an informed judgement that goes beyond the available evidence. We may believe (and have good reasons to believe) that it is the best big picture; yet we cannot show that it is true. What we do know, however, is that others have grasped this vision in the past, and transmitted this way of thinking and living to us. 

‘Decentring’ 

The Creeds are thus not a demand to believe, but a description of what has been found, an affirmation of its capacity to satisfy and sustain, and an invitation to explore, discover and inhabit this new world. The Creeds provoke us into looking beyond the world of familiar banalities, and being prepared to be receptive to strange truths, which others have found to be life-changing. The vision of reality that we find articulated in the Creeds might be described as “decentring” – a term used by Iris Murdoch to describe the process of breaking free from our worrying obsession to make everything focus on us. As Plato suggested in his famous analogy of the Cave, there is a greater world that lies beyond us which, once grasped, makes us see things in a very different way. For Christians, faith is about the discernment of this vision of reality, and deciding to act as if it were true, in the firm belief that it can be trusted – and living meaningfully and authentically as a result.

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.
