What is a Christian way to think about other religions? In the first part of this series, we established that there is no neutral standard or standpoint, and that we must always judge religions in light of some ultimate truth-commitment, even if for some that is only oneself. We must give up any pretence at the possibility of objectivity, or else we would be guilty of self-contradiction. Therefore, what I am now going to offer is a Christian approach to religious pluralism, with the caveat that it is not the only possible one and many Christians may disagree with it.

To be a Christian means to make Jesus Christ the ultimate standard of judgment and the light by which to discern truth from falsehood, good from evil. Jesus said, ‘I am the way and the truth and the life. No one comes to the Father except through me’ (John 14:6). Paul concurred: ‘there is one God, and there is one mediator between God and humankind, Christ Jesus’ (1 Tim 2:5). In other words, Jesus demanded absolute and total allegiance, and claimed to be the ultimate source of truth and spiritual guidance. He did not claim to be merely another wise teacher like Socrates, Confucius, or Mencius, whose sayings are followed because they make sense to the listener or because of the reputation of the speaker. Jesus wanted, not just to offer wisdom, but to invite us to leave everything and follow him, to submit to him as our master above all other masters.

Some people think that Jesus’ claim to ultimacy means that to follow Jesus means to believe all other religions are wrong. But this is a mistake.

The first point about this claim of Jesus is that it is far from strange or unique. The founder of every major world religion made similar claims about themself as the ultimate guide to truth. For example, Sri Krishna said, ‘I am the goal of the wise man, and I am the way. ... I am the end of the path, the witness, the Lord, the sustainer. I am the place of abode, the beginning, the friend and the refuge. ... If you set your heart upon me thus, and take me for your ideal above all others, you will come into my Being.’ Similarly, the Buddha said, ‘You are my children, I am your father; through me you have been released from your sufferings. ... My thoughts are always in the truth, for Lo! my self has become the truth.’ If Jesus had not claimed ultimacy for himself, he would not have founded a religion the way I am using the word (recall in the first part of this series, where I defined a religion as one’s commitment to what is ultimate).

Some people think that Jesus’ claim to ultimacy means that to follow Jesus means to believe all other religions are wrong. But this is a mistake. Jesus is claiming, not that you can find truth nowhere else, but that he is the ultimate authority or paradigm through which we view the world, to help us see what is true and what is false elsewhere. If Jesus is the truth, this in no way implies that every other religion is all lies or wrong from beginning to end. How could they be, when they agree on so much? It is a strange feature of the modern way of thinking that it loves to posit radical ‘either/or’ alternatives, without seeing the overlap, the layers, the inclusiveness of one thing in another, and the deeper synthesis which reconciles surface-level contradictions. A Christian perspective does not require believing that other religions are lies, but that they only have part of the truth where Jesus has it all. There is all the difference in the world between believing a lie, and believing only part of the truth. Let’s consider some of the other world religions. For a start, to be a Christian automatically implies agreeing with Judaism on a huge amount. Insofar as Judaism denies Jesus as the Messiah, there is a conflict. But this is not a positive belief of Judaism, only an absence where Christianity claims a presence. Similarly, for Christians to consider Islam ‘totally wrong’ is a massive failure of perspective, an inability to notice the enormous overlap Christians have with Muslims, not only on the One Transcendent Creator God, but on all kinds of ethical issues, prayer, worship, fasting and so on. Something similar applies to Hinduism, which is often mistakenly considered polytheistic only because of its reverent denial of the conceivability of Transcendence, from which some Christians would do well to learn. To notice first what we disagree on and let that obscure all the common ground is a failure of charity and graciousness, which makes it a fundamentally unchristian attitude.

There is all the difference in the world, as well, between calling Jesus the truth and calling Christianity a complete explanation for everything, as if Christians understood Jesus completely and had nothing more to learn. To believe in Jesus is not to understand even Christianity in all its fullness, let alone the ways in which Jesus is manifest dimly through cultures that have never heard of him, or who have heard of him only as a symbol of Western imperialism. St Paul says that for Christians, Christ is ‘before all things, and in him all things hold together’. That means everything has contact with Christ simply by being a thing, by existing. The apostle John writes: ‘All things came into being through him [the Word], and without him not one thing came into being. What has come into being in him was life, and the life was the light of all people’. So if anyone has life, they have their being in Christ, and the light of Christ reveals at least some truth to them.

For Christians, Christ is the fullness of the truth, and all else is only part of the truth. But Christians still have only part of the truth, because their knowledge of Christ remains incomplete and imperfect. Why could another religion not reveal something of Christ, as long as it didn’t contradict the trusted revelation of Christ in the Bible? How would we know, unless we took the time to listen and learn about other religions, without fear, without defensiveness, without needing to prove things or score points in an argument, also without compromising the ultimate authority of Christ as the supreme judge? Throughout the history of Judeo-Christian religion, the true insights of ‘outsiders’ have been accepted and become part of the faith of ‘insiders’. The Bible’s Book of Proverbs has chapters 22-24 lifted from Egyptian literature. The ideas of circumcision, a sacred temple, and a divinely appointed king all originated from practices in the surrounding nations, adopted and sanctified by Israel. St Paul quotes Greek poets as speaking truth about God. Justin Martyr recognised truths taught by Plato which enlarged the Christian understanding of God and the world. His maxim, “all truth wherever it is found belongs to us as Christians,” summarises the generous attitude Christians ought always to have in their search for wisdom and truth, without ever watering down the fullness of the truth in Christ.

True tolerance, as John Dickson puts it, isn’t the easy acceptance of every viewpoint but the noble ability to love those with whom we deeply disagree.

Concluding thoughts for those on a journey

We cannot expect all religious people in the world to come to agreement quickly and without great labour of understanding, love, and forgiveness. In the meantime, I propose the following attitudes for everyone, whether Christian or not, who acknowledges their own limited and non-objective perspective and yet is serious about the quest for ultimate reality.

Provisionality: faith is a journey, truth is a destination. To call it ‘faith’ means that it is not certain, that it is provisional, that it can grow and change. Everything you believe is always provisional. Never say ‘I will never change my mind on this’ because you do not know the future. This is particularly true for Christians. Rowan Williams describes Christianity as a basic life commitment which one takes before having all of the facts and evidence. In other words, to be a Christian means to be betting your entire life that following Jesus is the best way to live. You can’t prove this, you can’t be certain of this. You can’t even evaluate its likelihood from any neutral or objective standpoint. But you only have one life, and how you spend it will be your bet.

Authenticity: live your beliefs to the max. That is the only way you may find them to be false, or the only way others will be attracted to them if they are true. Much of the confusion in the world is a result of hypocrisy. Do not add to it. Learn also to articulate your own beliefs clearly to yourself and others. This means getting to know them by diligent study.

Empathy: learn to see the world from other points of view. In 2017 the world’s top religious leaders issued a joint appeal: “make friends with followers of other religions.” Some people say there is too much talk and not enough action in the world. I say there is not enough real dialogue, not enough listening, which implies someone is talking. No harm can be done to anyone’s faith by listening, seeking to understand, not prejudging. And for Christians, it is a requirement, not an optional extra, because it is the basis of love. True tolerance, as John Dickson puts it, isn’t the easy acceptance of every viewpoint but the noble ability to love those with whom we deeply disagree.

Hope: the truth gives itself to be known. The universe does not fundamentally lead astray those who seek the truth with all their heart. This cannot be proven. That is why it is called hope. But certainty is not a luxury granted to anyone. You only have a choice between hope or despair, i.e. hope or its absence. Neither option makes more rational sense than the other, yet as life-attitudes they pervade your every choice and belief. Which one will you adopt as your own?

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.
