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.

Alister McGrath retired as Andreas Idreos Professor of Science and Religion at Oxford University in 2022.

“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which seems out of place in today’s more sophisticated world, informed by science and philosophy rather than outdated worldviews inherited from a credulous past.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.

Of trees and truth: Tolkien on cultivating greenness

The literature of Herbert, Lewis and Tolkien all helps us see the seen and unseen better.

Each Easter season I return to a poem called “The Flower,” written by the Anglican priest George Herbert and published shortly after his death in a collection called The Temple. In both its growth and its withering, the flower of the poem represents the poet’s spiritual life, and the verses speak powerfully to the renewal that only God can bring. “The Flower” opens in joyful exclamation— 

“How fresh, oh Lord, how sweet and clean  

Are thy returns! even as the flowers in spring” 

—but my favorite image appears at the start of the second stanza, where the poet marvels,  

“Who would have thought my shriveled heart 

 Could have recovered greenness?”  

C.S. Lewis took note of the second stanza as well. At the Marion E. Wade Center at Wheaton College, Illinois, where I work, we care for nearly 2,500 of the books that Lewis had in his personal library, many of which include his notes and underlinings. Lewis’s copy of The Temple is no exception. The back pages of the book contain a carefully constructed index in Lewis’s own hand, and one of the index entries points us back to the concluding words of the second stanza of “The Flower.” Turning to the poem, we find a hand-drawn line, very likely added by Lewis himself, running down the page alongside the stanza. I find that line to be heartening—a pointer, perhaps, to a shared interest. And though the connection between poem’s verses and the book’s appearance is purely coincidental, I appreciate the fact that Lewis’s copy of The Temple has a weathered green cover.  

What I love about “The Flower,” and about Herbert’s poetry more generally, is that it helps us see the seen thing better, helps us pay attention to it, so that we may glimpse the unseen thing. By bringing the flower into clearer focus, Herbert helps strengthen the eyes of faith. Herbert does not present nature itself as divine—the flower is a metaphor, after all—but he does represent nature in ways that point to its beauty while testifying to who God is and who we are in relation to Him.  

How during this Easter season might we recover greenness in Herbert’s sense? The poetry of The Temple is an excellent starting place. But if you are looking for another literary guide, I recommend turning (or returning) to another writer whose works we collect at the Wade Center—J.R.R. Tolkien. Should you visit the Wade to pore over the annotations in Lewis’s books, you’ll also have the chance to examine the small oak desk upon which Tolkien penned The Hobbit.  

In a note to his American publisher in June of 1955, Tolkien wrote,  

“I am (obviously) much in love with plants and above all trees, and have always been; and I find human maltreatment of them as hard to bear as some find ill-treatment of animals.”  

The parenthetical “obviously” is significant. Though Tolkien didn’t view The Lord of the Rings as autobiographical, he was willing to admit that his love of plants and trees was on full display in his life and work.  

Tolkien’s faith was on display in his writing as well, as Holly Ordway argues in her remarkable book Tolkien’s Faith: A Spiritual Biography. Ordway’s first chapter begins with Tolkien’s own words on the matter: “The Lord of the Rings is of course a fundamentally religious and Catholic work; unconsciously so at first, but consciously in the revision.” As with Tolkien’s “obviously” so too with his “of course.” After calling our attention to the latter, Ordway persuasively demonstrates the truth of Tolkien’s words, exploring in detail how his religious convictions and practices were indeed fundamental to him and his work. “The Lord of the Rings is not an allegory of the Gospels or a tale didactically expressing Christianity,” she writes. “Rather, the whole world of Middle-earth and everything in it is infused with, rooted in, its author’s Christian vision of reality.” 

Ordway’s metaphor of rootedness is a fitting one, and—in our pursuit of Herbert’s greenness—it is worth exploring the entanglements between the obvious and fundamental aspects of Tolkien’s work: his love of “growing things” (to borrow a phrase from Treebeard) and his faith.  

Consider a few of the trees that we find across Tolkien’s writings.  

In his poem “Mythopoeia,” Tolkien responds to C.S. Lewis’s view (before Lewis converted back to Christianity) that myths are beautiful yet untrue. Tolkien begins the poem among the trees, expressing Lewis’s views as follows:

“You look at trees and label them just so,

(for trees are ‘trees’, and growing is ‘to grow’).”

The problem with viewing nature in such purely naturalistic terms, Tolkien goes on to suggest, is that it ignores the origins of terms like “tree.” It leaves out the humans who name the things of the world and develop myths about them and, more importantly, it leaves out the Source of such creativity. For Tolkien, human creativity finds its beginnings in God, and we reflect Him through acts of sub-creation. Thus he writes,  

“The heart of man is not compound of lies, 

 but draws some wisdom from the only Wise, 

 and still recalls him.”  

Whether it is the simple act of identifying a tree by name or the complex development of stories across time and place—what Tolkien describes elsewhere as “the intricately knotted and ramified history of the branches on the Tree of Tales”—our creativity flows from, and is a form of reverence for, the One who created all things. 

In The Lord of the Rings, we encounter not just trees but also the tree-like Ents. Referring to himself and the other Ents as “tree-herds,” Treebeard explains to Merry and Pippin that the Ents help the trees grow and develop:  

“We keep off strangers and the foolhardy; and we train and we teach, we walk and we weed.”  

In line with Ordway’s quotation above, Tolkien’s Ents are not meant to be read allegorically; however, the tree-herding activity of the Ents reinforces the theme of stewardship in The Lord of the Rings—a theme that echoes Scripture’s call to humans to care for creation and, just maybe, encourages us to take up similar work in our own places. (For further encouragement along these lines, check out Kristen Page’s book The Wonders of Creation: Learning Stewardship from Narnia and Middle-Earth, which grew out of Page’s lectures for our annual Ken and Jean Hansen Lectureship at the Wade Center.)  

And in Tolkien’s short story Leaf by Niggle, we encounter an artist desperately trying to work on his painting of, yes, a tree. This tree stands for our efforts to create art, which, though frequently frustrated and often motivated by self-interest in this life, may be purified and brought to fruition in the age to come.  

Tolkien’s trees testify to the beginning, middle, and end of Christian story. Among their roots and trunks and branches, we encounter illustrations of his views about creation, the proper ways to care for it, and its culmination.  

In a 1945 letter, Tolkien told his son Christopher about an essay by Lewis on the truth and beauty that we find in the story of Scripture. In the essay, which Ordway observes is likely his piece “Myth Became Fact,” Lewis argued that people of faith are, in the words of Tolkien’s letter, “meant to draw nourishment from the beauty as well as the truth” of the story. But what of the person without faith who “clings” only to its beauty? According to Tolkien, Lewis maintained that such readers “still in that way get some nourishment and are not cut off wholly from the sap of life.”  

Greenness for Herbert is ultimately the Lord’s doing. We should seek, therefore, to find nourishment in the truth and the beauty of Scripture, the source of the sap of life. Growing things spring up from these pages as well: fruit trees and fig trees and oak trees and olive trees; vines and branches; a new shoot springing forth from a stump, a crown of thorns, the wood of the cross. And as the Psalmist reminds us, the one who “meditates day and night” on the law shall be “like a tree.” When we read and digest the Word of life, we grow greener.
