“The Truth of Christianity” and reasons and influences leading non-believers to dismiss the Christian worldview.
Note: I was assigned this very “small” topic (Ha!). Forgive the length and if I don’t do it justice.
The Truth of Christianity
The truth of Christianity simply is Jesus Christ.
The truth (veritas) of Christianity rests on the claim that the second person of the Triune God became incarnate in Jesus of Nazareth: The only begotten Son of God, begotten of the Father before all worlds, God of God, Light of Light. Very God of very God, begotten not made, being of one substance with the Father, by whom all things were made.
These familiar words of the creed are anchored in what Jesus said to Pilate, what he told his disciples, and how they, the Apostles and the Church came to understand who he was, who he is.
Pilate asked him, ‘So you are a king?’ Jesus answered, ‘You say that I am a king. For this I was born, and for this I came into the world, to testify to the truth. Everyone who belongs to the truth listens to my voice.’^ ^ Pilate asked him, ‘What is truth?’ (John 18: 37–38[1])
When he says he “came into the world,” it was more than a declaration of his mission; it alludes to his pre-incarnate existence. Jesus of Nazareth, born of Mary, who stood in front of the Roman governor charged with sedition, preexisted the whole cosmos into which he was born and the marble floors of the Judean headquarters on which he stood. This allusion became explicit when John the evangelist was inspired to write:
In the beginning was the Word [Logos], and the Word was with God, and the Word was God. He was in the beginning with God. All things came into being through him, and without him not one thing came into being. . ..
He was in the world, and the world came into being through him. . ..
. . . [T]he Word became flesh and lived among us, and we have seen his glory, the glory as of a father’s only son, full of grace and truth.
And when St. Paul declares this grand mystery of reality to the church at Colossae:
[the Father’s beloved Son] is the image of the invisible God, the firstborn of all creation; for in him all things in heaven and on earth were created, things visible and invisible, whether thrones or dominions or rulers or powers—all things have been created through him and for him. He himself is before all things, and in him all things hold together. He is the head of the body, the church; he is the beginning, the firstborn from the dead, so that he might come to have first place in everything. For in him all the fullness of God was pleased to dwell . . ..
Jesus told Pilate that the reason he was born, the reason he came into this world was to testify to the truth. And he says everyone who belongs to the truth listens to his voice. Which prompts Pilate’s famous question. Maybe it was rhetorical. Maybe not. Either way the question has echoed through the ages and through the annals of philosophy and everyday life. Yet there is something in this exchange we should not miss. If the whole reason the second person of the Trinity entered this world was to testify to the truth and that everyone that belongs to the truth listens to his voice, the truth of what is being said by his voice must be the whole of who he is.
This is what lies behind what Jesus had earlier told his disciples, that he himself is the truth, (John 14: 6). The voice of Jesus is the Word made flesh, the Logos of God.
Logos has a variety of meanings or uses. Among the most often cited meanings are “reason” or a “principle of order and knowledge” or “the logic behind an argument,” even the “generative principle of” and “divine animating principle pervading” the universe.[2] St. John certainly had all these in his mind when he wrote his Gospel, in part because he lived in a Hellenistic Greek-minded world and wanted the scope of his declaration about Jesus Christ to be all encompassing. However, even among all these varied meanings, the most straightforward and base meaning of logos is “discourse,” as in speaking, having a conversation, communicating, even intimacy, as one has in a relationship. This means the most dominant image in the Christian story is one of relationship. God’s Logos/Word relation to his creation is not distant, abstract, or capricious but fundamentally relational. It is not so just in that he has and does actually speak, in word and deed, though he has and does. It is fundamentally the way God relates to his creation. There is a discourse relation between God and creation built into nature, an expression of overflowing and incessant love.
This basic Logos/Word relation between God and his creation is what I call the “language and vocabulary of the human heart.”[3] It is not just with words that we have the capacity know God. His word-language relation with creation is a basic, fundamental way we experience his presence. This is why the metaphor of mythopoesis, or story, is more than just a metaphor. It is real. This is a natural expression and therefore a natural sign of our participation in God’s Grand Story. It is an indicator of [what St. Augustine calls] capax Dei, the capacity to know God.[4]
This relation of God with his creation through his only Son the Logos is the echo of the Truth that the human heart and intellect reaches for. This is why the church has traditionally said all truth is God’s truth. Jesus Christ is the source of all truth because he is the truth. It is why, as he told Pilate, everyone who belongs to the truth listens to his voice. His divine condescension is like a shepherd calling his sheep. They hear his voice and listen to it. It is the voice of the author of all things echoing through every crevice of his creation. That “beckoning from a voice we have not yet fully heard to a place we have not yet fully known, yet with a clear sense that somewhere there is a true home”[5]—like Psyche longs for the Grey Mountain in the distance in C. S. Lewis’s Till We Have Faces. That restlessness in the human heart until it finds its rest in him.
This is why Jesus Christ is the truth of Christianity.
Reasons and influences leading non-believers to dismiss the Christian worldview
The Christian claim above is not one among many different possible truths. It is a claim about reality as such. Human beings have always sought to know and understand reality and have come to know a good deal about it because of the gift of human heart and intellect. But the grand story of reality set out above is only glimpsed at and knowable only in part by natural reason and poetic knowledge. The fullness of reality is made known to us only by God’s self-disclosure. The fullness of that revelation is the incarnation, life, death, resurrection, and ascension of Jesus Christ, even if we still understand only in part.
If this Christian claim is not true, it means nothing. If it is, it means everything.
It means everything because it is the true story of reality. Yet to say this is not to say that all other religions, metaphysical systems and scientific claims are completely erroneous. Indeed, Christianity has always acknowledged that there is truth to be found in most all religions and intellectual and scientific pursuits.[6] This is because the human heart and intellect naturally reach for The Truth. Christianity holds that the pursuit of human knowledge and truth are part of the imago Dei in man. We are all drawn to the pursuit of knowledge and truth. It’s part of our nature.
If this is the true story, why then are there so many non-believers? And what are some of the key reasons and influences leading non-believers to dismiss the Christian worldview.
First, it is not that there are insufficient reasons to believe. Yet “[n]o amount of argument or intellectual credibility will by itself cause anyone to have life-transforming faith in God. But a genuine encounter with God always will.”[7] The deepest problem with disbelief in the Christian story is one of will and disordered loves. All of us are stricken with this problem. Only God’s grace can release us from this prison. Only his grace will effectuate the faith we need to believe.
That said, there are reasons and influences for many that make belief in the Christian worldview quite difficult in our modern world. Among the many reasons include how Christians and church have failed to live up to their own faith — e.g., moral failures of the church, hypocrisy of individual believers, and the shallowness of too many churches and believers. But many non-believers believe that religious faith is simply irrational in the light of modern science and modern philosophy. Exploring the reasons and influences is a big topic so I will need to be brief (if still way too long). In sum, I am convinced that among the biggest reasons is that in modernity we have become willing to live comfortably with incoherence — we’re willing to leave some of the biggest questions unasked and unanswered. The result is we think non-belief is the most coherent, the most rational. But upon scrutiny, it’s the opposite. To show this incoherence I will restrict my comments to one major reason and influence: the shift from an open world structure to a closed world structure metaphysic; and one major conundrum created by a closed world structure view: the idea that human knowledge should yield anything like truth.
Open and Close World Structure
One of the most succinct ways to think about the core reason why non-believers dismiss the Christian worldview is the way philosopher Charles Taylor puts it in his book A Secular Age. He describes how in the passage from the pre-modern to the modern period we moved from an “open world structure” to a “closed world structure.” From a belief that all material reality (all of nature) obtains and maintains its existence from a transcendent reality beyond the material to a belief that there is nothing but material reality. Here’s an illustration I created.

The core difference between the pre-modern and the modern worldview is its metaphysical vision. The pre-modern vision, especially under the influence of the Christian vision, is an open world structure. All that has being (existence) is because God gave it its being and holds it in it being—as St. Paul told the philosophers on Mars Hill, God made the world and everything in it, and drawing upon their own familiar poets he said, “In him we live and move and have our being.” (Acts 17:22–29 Emphasis mine) In philosophical language, being as-such gave all of what we know as the universe (or any other possible universes) its being and holds it in its being. If God should for one second not hold the created order in its being, it would not exist. God is transcendent to his creation. God is self-existent, and the existence of his creation is contingent to him. He is the source of all that exists. In Aristotelean terms, contingent being exists only from un-contingent being — the unmoved mover. In the modern outlook, the being — the existence — of anything at all just is. It source, if any, is from is some other contingent existence, like another universe or multiple other universes (multiverse theory). This is not a real answer to existence as-such; it just pushes the question of existence further back.
Thus, for moderns who adopt a closed-world structure, there is no transcendent reality. There is no God or gods. There is only material reality. This is the core difference. This is the core reason non-believers have a hard time with the Christian worldview.
The passage to modernity led to skepticism of transcendence. Over time this became the default outlook making belief in God irrational. See here how John Searle puts it:
This world view is not an option. It is not simply up for grabs along with a lot of competing world view. Our problem is not that somehow we have failed to come up with a convincing proof of the existence of God or that the hypothesis of an afterlife remains in serious doubt, it is rather that in our deepest reflections we cannot take such options seriously. When we encounter people who claim to believe such things, we may envy them the comfort and security they claim to derive from these beliefs, but at bottom we remain unconvinced that either they have heard the news or they are in the ‘grip’ of faith.
John Searle, The Rediscovery of the Mind (1992)[8]
“The news” Searle is referencing is that belief in God is irrational. Which is to say that his view is the most rational. It reflects a narrowed view of reason. One that adopts applies the scientific method to all questions. The modernist outlook tends to assume this fixed and restricted notion of rationality: scientific rationality; can the question at hand be proven using inductive scientific or pure deductive reason methods? When the question of God and his revelation is asked in this restricted view the answer must be what Searle concludes: God and revelation are irrational. The problem with this answer lies in its methodological foreclosure to any other possible answer. Philosopher William Abraham says this reveals a problem in the way we practice epistemology today in general and specifically in reference to the question of revelation. We are trapped into this answer by what Abraham calls epistemological “methodism.”[9] We declare scientific or logical positivist method of knowing to be the proper epistemological one. We therefore we must judge claims of the existence of God and his revelation to be irrational, without warrant, and not real knowledge.
To be clear, of course, it’s not that the empirical method is faulty. It is not. It has provided us with extraordinary discoveries and understanding with modern science. But behind the adoption of this method exclusively lies a philosophical problem. There are big questions it simply cannot answer. One huge one is idea of human knowledge and the notion of truth.
The Idea of Human Knowledge and That it Should Yield Anything Like Truth[10]
That humans can know anything that should yield anything like truth is a mystery, just as existence is. That we obtain knowledge of any sort is not debatable. Why we do and that the knowledge we obtain should yield truth is.
The Open-World-Structure View
In the open-world-structure view, particularly the Christian view, the capacity that humans have for knowledge is directly related to God. We know, “through a glass, darkly,” because God knows. Human beings are a reflection of God, and all true human knowledge reflects The Truth that abides in God.
How we obtain knowledge is diverse: it is through natural reason, including logic, and rational-sensory experience (and experimentation); it is through imaginative, artistic and poetic life, which C. S. Lewis says is the meaning that gives reason its fodder; and it is through God’s special revelation of himself to his creatures, including God’s self-disclosure in his acts, his Spirit’s disclosure to and through people, and most fully in his self-condescension into his creation in his son, the Logos of God. All of these are thoroughly rational and consistent with God who is in constant relation with his creation, upholding it in its being. Without God there would be no being as such nor any actual knowledge and truth, or at least none that we should have any confidence constitutes actual knowledge and truth.
In an open-world structure—at least in something like traditional Christian metaphysics—all knowledge is ultimately sourced in God, even if not acknowledged. In at least this sense all knowledge is about God. If, as Christianity maintains, God is truth, all knowledge therefore finds its truthfulness in God. In the broadest terms, without a transcendent source, human knowledge that yields anything like truth is either a mystery (like the “brute fact” faith of the naturalist on the question of existence) or, more likely, incoherent (and in deep conflict with the empirical science the naturalist so relies on).
The Closed-World-Structure View
In the closed-world-structure view, human knowledge is sourced in the world and in the knower. What counts as knowledge is only that which is about the world found through reason, logic, and rational-sensory experience. Only knowledge about things of the world can be considered actually true—based on the fundamental notion that there is an actual “way things are.” Other things we call “knowledge,” “true,” or “truth” are either expressions of human subjectivity or what a group of knowers agree upon.
What is “true” or “the truth” in a contingent-plane-only reality is always relative. It must be. For all scientists (whether open- or closed-world), for whom the contingent plane of nature is the domain, truth is always relative—or better, tentative—and subject to further knowledge of what is known now. For all scientists, there is an assumed “truth of the matter” with respect to material reality. And, all scientists acknowledge that what they know about the “truth of the matter” is what we know now. All scientific truth is relative to “from where we stand, with what we know now.” This is the way all science works. It is driven by ignorance, coming to know some things which then raise new questions about what is not yet known.[11] Science is primarily a methodology—a way of discovering and inferring what nature is and how it works. Scientists form theories, or “models,” that can hold what is known now and form new ones when new discoveries cannot be held in the old theories or models. For the politician or social theorist who adopts closed-world-structure naturalism, notwithstanding the same moniker “scientists,” there is no “way things are,” no nature as it were. Morality, law, and truth are relative to whatever the society and culture they are part of decide is “true.” “Truth” is pure social construction.
For the scientist (all scientists), therefore, truth is measured against what we know now—which is as it must be. But for the closed-world naturalist scientist who steps out of the role of scientist and becomes a metaphysician or social theorist or ethicist and begins to declare what a human being is or what should be done because we know what human beings are and what is good, just, and true, that scientist has made absolute assertions from provisional knowledge. Science’s plane of study is material existence, which is always changing. It assumes material reality. That is its field of study. The measure of truth is against this reality alone. Notwithstanding whatever we may discover by science, in a closed-world structure metaphysic, nonmaterial things, like concepts such as beauty, goodness, morality, justice, personhood, identity, gender, and so on, must be either purely material or physical phenomena or only social constructions (not real).[12]
Furthermore, though all scientists believe there is a “way things are” and we slowly but surely learn more about what that is, once the closed-world structure naturalist metaphysics position is taken, the naturalist faces a conflict with science—one that the theist does not face. In closed-world-structure naturalism, there is no reason we should trust that human cognition should yield anything like truth or that what we know should be or is true. This closed-world view must hold to a nondirected, wholly random form of cosmic and biological evolution. The problem is not with science or with evolution as such but with philosophical naturalism. Naturalism must on the one hand hold that knowledge is real and rises to the level of real truth about the way things are, and yet on the other hand has no logical explanation for why this should be so. It is wholly illogical to believe that we should trust human cognition to yield true, reliable beliefs or even true knowledge. Those who hold this outlook should doubt whether it is true. And many of the best minds within the camp of naturalism have openly done so. Darwin did: “‘With me the horrid doubt always arises whether the convictions of man’s mind, which has been developed from the mind of lower animals, are of any value or at all trustworthy. Would anyone trust the convictions of a monkey’s mind, if there are any convictions in such a mind?’ Nietzsche, Nagel, Stroud, Churchland, and Darwin, nontheists all, seem to concur: (naturalistic) evolution gives one a reason to doubt that human cognitive faculties produce for the most part true beliefs.”[13] As such, naturalists should either seriously doubt their belief that there is no transcendent explanation for the concurrence between our cognitive faculties and what we experience, or seriously doubt their belief that their cognitive faculties are delivering true, reliable beliefs, or knowledge, including the belief that somehow, in some way, a material-only reality caused reliable cognitive faculties to develop such that we should trust them. Either way, naturalism has a problem.[14]
An open-world structure that holds to theism, in particular the Trinitarian theism of Christianity, does not have this problem. It has the most rational, coherent reason for human knowledge and truth: God. With knowledge grounded in God, we obtain an answer to an even more visceral question about knowledge: Why are we drawn so incessantly to pursue it? The answer is found in St. Bonaventure: “All knowledge [is] integrated into a spiritual journey toward love; love of God and love of fellow human beings.”[15] Even in our pursuit of knowledge, we are longing for God.
The Limits of Scientific Knowledge
The unalloyed mystery that science demonstrates so well is that nature is orderly. Because of this order we can come to know and have a significant understanding of it. But science is limited in scope. It explores and seeks to understand only the contingent plane of existence, what we call nature.
Science, which is primarily a methodology for knowing, is the best way we have for discovering what the makeup of nature is, how it works, and to some extent how what we now observe came to be as it is now. This is an invaluable source of knowledge, especially practical knowledge. But science’s scope and its methods have limitations. By default, science can only answer questions within its scope. It cannot answer questions about existence that are not within the contingent plane. Anything beyond the contingent plane, and certain phenomena in it that are not physical properties beyond how they work and their chemistry, science cannot address: for example, what consciousness actually is and what love is. Science explains what is in the contingent plane of existence, how it works, and how it moves from what it was to what it is now. It cannot explain whether there is anything beyond the contingent plane, nor why anything in that plane exists except in terms of the processes that explain how they came to be what they are now. Science is impotent on metaphysical questions.
This is not to say that reason cannot address such questions, only that science’s material and efficient cause-effect methodology cannot. Logic, which is a human capacity that science uses but that is not equivalent with science nor can science explain it, and speculative reason can address metaphysical questions. (This is so, I suggest, despite the Kantian tradition that suggests no such metaphysical knowledge is possible.)
The closest science comes to metaphysical questions is in its findings. Science’s findings reveal how improbable the universe (or universes it may theorize) it studies really is. This is seen best in what is often called the “fine-tuned argument.” This argument suggests that the contingent reality that science observes and seeks to understand is found to have such narrow tolerances for the conditions necessary to spawn and sustain life that it must have a deeper reason behind it—an intelligence behind it that made it in just this way such that life could develop and be sustained. The staggering coincidences are otherwise too improbable. The most recent theory to explain these improbabilities put forward by closed-world-structure cosmological scientists is the multiverse theory outlined by Stephen Hawking and Leonard Mlodinow in The Grand Design. In this view the improbabilities that are present in this (our) universe are accounted for by there being many universes, enough so that it is only reasonable to assume that with enough time, the otherwise improbable constants and chemistry found in our universe that are necessary to sustain life would occur.
Most scientists are not philosophers. Their work, again to use Lewis’s comments on models, is to observe the reality they have at hand and perform experiments and come up with theories that can best explain it. They look for the theory/model that can best “hold it all.” So it is reasonable that scientists would theorize a multiverse to explain what is observable and use math to confirm the plausibility of their theories of cosmology. It is more than appropriate that philosophers would take this data into account in their pursuits. But in the end, the scope of the scientist’s work doesn’t and cannot reach beyond its domain—again, as [David Bentley] Hart points out, cosmology cannot become ontology.
But no human knowledge-seeking enterprise of any kind operates outside of a philosophical framework. Within this framework are embedded answers to a host of nonscientific questions—whether well considered and articulated or not. Among the nonscientific questions are the question of existence itself, the question of contingency, the question of knowledge, the question of logic, and the question of human cognition and conceptualization, among a host of others.
Being a good scientist does not include or preclude judgments about transcendent reality, or God. Most of the greatest scientists have believed, even if not always in traditionally orthodox terms, that the universe (or multiverse) did not just come about and is sustained on its own but must rely on a transcendent source, God. The limits of scientific knowledge are not a weakness; they are simply a limitation of scope. Listen to Oxford Professor Michael Ward on C. S. Lewis’s understanding of the narrow scope of science:
The smallness of scientific statements is often obscured by their successfulness. Scientific statements succeed in defining and predicting certain pockets of the natural world, definition and predictions which can then be put to use, in curing small-pox, or building the internal combustion engine, or devising the microchip. The magnificence of such scientific achievements is so huge that it can mislead us into thinking that they have said a great deal, when actually they have said relatively little, but said it very well. A true scientific statement has to be relatively small, because it is only relatively small things that can be said with sufficient univocality to be empirically verifiable or falsifiable. You might think it preposterous to describe the mapping of the human genome as a “small statement,” but genetics is only one department of biology and biology is only one department of science and science is only one department of human knowledge. Seen in context of all that there could possibly be said about a human being—socially, psychologically, spiritually, economically, historically, geographically, emotionally, visually, audibly, tangibly, olfactorally, racially, anthropologically, dermatologically, psephologically (you get the picture!), any genetic statement, however marvelously correct, is still a minuscule fraction of the total. When you start trying to make larger statements you move into the language of the humanities and then into the arts and then into religion. Religious statements, by saying things which attempt to explain life in the round, use language which is very hard to quantify, to measure, to test. But that is because they are trying to say a very great deal; they are trying to find the unity, the oneness, the heart of all reality. Here the stake is not a mere thirty shillings, but every penny you have, your life, your soul.[16]
There is so much more to be said about the reasons and influences leading non-believers to dismiss the Christian worldview. But this will have to do for now.

[3] In support of this idea, see Candler, “Tolkien or Nietzsche.” In particular note Candler’s comment that for Tolkien in comparison to Nietzsche, “Christ is capable of ‘transubstantiating’ all moments of human poiesis. The Word who is before all worlds, who creates all worlds, who was made flesh and dwelt among us—does not all creation speak, in an infinite variety of tones, keys, timbres, and tongues, of that Word? Does not the Word made flesh render all flesh in some sense articulate?” (123). Editor Ralph Wood, in his introductory comments on Candler’s essay in Tolkien among the Moderns, says, “Tolkien is not at all troubled by the linguistic character of both divine revelation and human truth. Rather than leading to nihilism [Nietzsche’s contention], our irreducible linguisticality proves, in Tolkien’s work, to be our abiding hope, since human beings are sacramentally created to participate in the life of the triune God, who creatively speaks all things into being” (3).

[9] “Methodism” for Abraham is, of course, not a reference to Methodist Christians (though he himself a Methodist). It refers to the development of a big-picture approach or theory of rationality, justification, warrant and knowledge, and evaluating the rationality of belief in God, an in the specific case he is considering, revelation from God, in the light of the methodology adopted by the theory. This he calls a “Methodist” approach versus a “particularist” approach. Particularism, in epistemology and in reference to the subject of revelation, is to take a serious look at specific claims of revelation (the phenomena of specific claims to revelation from God) and evaluate them not with pre-defined epistemic categories but to determine if the claims themselves can marshal epistemic warrant considering a wide array of epistemological methods and principles. This approach, Abraham suggests, does not prejudge whether revelation can occur within the boundaries of a specific grand epistemology; but rather allows the claims to stand unless there is a good reason not to. For an explanation of the terms methodism and particularism as used by Abraham, see Ibid., p.30ff.

[13] Plantinga, Where the Conflict Really Lies, 316.
[14] This way of framing the problem of knowledge and truth in closed-world naturalism is addressed in Plantinga, Where the Conflict Really Lies. The explicit argument is that whereas it is often thought that there is a deep conflict between religion and science and no conflict between philosophical naturalism and science (basically a closed-world-structure view), the reverse is the case. Plantinga shows that between religion and science there is only superficial conflict and that there is deep conflict between naturalism and science, particularly between naturalism and current evolutionary theory in science. Plantinga concludes that “one can’t rationally accept both naturalism and current evolutionary theory; that combination of beliefs is self-defeating. [And] there is a deep conflict between naturalism and one of the most important claims of current science.” Plantinga, Where the Conflict Really Lies, 349–50.
