This collection of arguments critically examines the common claim made by Christian apologists that secular systems “borrow” essential concepts—such as morality, justice, free will, and human dignity—from the Christian worldview. The essays delve into the motivations behind this claim, which include portraying Christianity as the indispensable source of truth while framing secular worldviews as ideologically inferior or incoherent. By addressing these claims through historical evidence, philosophical critique, and symbolic logic, the discussions demonstrate that such arguments often oversimplify the origins of universal human values. Concepts like love, compassion, and justice are shown to have emerged across diverse cultures, predating Christianity and existing independently of its theological framework.

The essays below will also reveal the self-defeating nature of the borrowing argument. If borrowing renders a worldview inferior, then Christianity itself—built on ideas borrowed from Judaism, Stoicism, and Greek philosophy—would fail by the same standard. Through formal logical analysis, contradictions in the apologists’ reasoning are exposed, demonstrating that the claim lacks consistency and validity. Rather than dismissing borrowing as a flaw, the essays argue that it reflects the collaborative and evolving nature of human thought. Readers are invited to explore how the universality of values and the shared heritage of ideas enrich our understanding of morality, justice, and human purpose, providing a foundation for more constructive and inclusive dialogue.


Borrowing Percentages and Commentary

  • Those who disagree with the content of this table and the relevant arguments are strongly encouraged to provide counter-arguments in the comments section below.

One recurring argument advanced by Christian apologists is the claim that secularists, atheists, or followers of other worldviews must “borrow” elements of their ethical, logical, or philosophical systems from Christianity. This claim often revolves around themes like moral values, human dignity, justice, free will, or a sense of transcendence, with the apologist asserting that these concepts are fundamentally rooted in Christian theology and cannot stand independently in a secular framework. While at first glance this claim might appear to be a mere debate tactic, a closer analysis reveals underlying motivations that are both strategic and psychological in nature. Chief among these motivations is the desire to portray Christianity as an indispensable source of truth and to render competing worldviews ideologically inferior.


At its core, the “borrowing” argument posits that secular worldviews are parasitic, reliant on Christianity for their intellectual coherence and moral compass while denying the theological framework that allegedly sustains these concepts. For example, apologists often argue that the concept of universal human rights—so central to secular liberal thought—is inconceivable without the Christian belief in humans being made in the “image of God.” Similarly, they may claim that secular morality is ultimately hollow without divine authority, or that logic itself requires a rational Creator for it to hold any validity.

Such arguments are presented as sweeping critiques, suggesting that non-Christian worldviews cannot account for the principles they profess to hold dear. The rhetoric is often paired with a sense of incredulity, implying that secularists are either delusional or dishonest for not acknowledging the supposed Christian roots of their values.


1. Reinforcing the Primacy of Christianity

One primary motivation for advancing the borrowing argument is to reinforce Christianity’s position as the ultimate and indispensable source of truth. By claiming ownership of universally admired concepts like morality, justice, and human rights, apologists frame Christianity as the intellectual foundation of civilization itself. This strategy elevates Christianity above all other worldviews, asserting its indispensability and suggesting that any attempt to discover or build a humanistic system apart from it is doomed to failure.

2. Undermining Competing Worldviews

The borrowing argument functions as a direct critique of alternative worldviews, particularly secularism, atheism, and naturalism. By accusing these systems of relying on Christian ideas while denying Christianity itself, apologists position secularists as inconsistent, incoherent, or hypocritical. This line of reasoning seeks to cast doubt on the intellectual integrity of secular frameworks, portraying them as unable to stand on their own two feet.

3. Deflecting Criticism of Christianity

Another motivation lies in deflection. By focusing attention on the supposed borrowing of secularists, apologists can shift the conversation away from weaknesses or criticisms of Christianity itself. Instead of addressing issues such as biblical inconsistencies, problematic historical practices, or theological dilemmas, the apologist redirects attention to perceived deficiencies in secular systems.

4. Psychological and Evangelical Appeal

The borrowing argument is also psychologically and rhetorically powerful within evangelical contexts. For Christian audiences, it reinforces a sense of superiority and security in their faith, affirming the belief that their worldview is not only morally right but intellectually necessary. At the same time, it functions as a subtle form of evangelism, aiming to unsettle secularists by making them feel ideologically dependent and potentially nudging them toward reconsidering Christianity.

5. Creating a False Dichotomy

The borrowing argument often relies on a false dichotomy: either a concept like morality comes from Christianity, or it is entirely baseless. This binary framing excludes the possibility that philosophical ideas can emerge independently across cultures or traditions. By insisting on this dichotomy, apologists leave little room for secular or non-Christian systems to claim legitimacy.


Ironically, if we apply the same “borrowing” criteria to Christianity itself, we see that it too is guilty of drawing heavily from pre-Christian traditions. Many of the concepts Christians claim as uniquely their own were developed in earlier philosophical, religious, or cultural systems.

  1. Morality in Greek Philosophy:
    The ethical frameworks of Plato and Aristotle, emphasizing virtues like justice, courage, and moderation, laid the groundwork for much of Christian ethical thought. These ideas were absorbed into Christian theology during the Scholastic period, particularly through the work of Thomas Aquinas.
  2. Universal Human Dignity in Stoicism:
    The Stoics taught that all humans are part of a universal brotherhood and share the same rational nature, a concept remarkably similar to the Christian idea of universal human worth. These ideas were prevalent in the Roman Empire long before Christianity’s rise.
  3. Love and Compassion in Buddhism and Confucianism:
    Teachings of loving-kindness (mettā) in Buddhism and compassionate reciprocity (ren) in Confucianism predate Christian notions of love your neighbor by centuries. These traditions demonstrate that love and compassion are not exclusive to Christianity.
  4. Mythological Parallels:
    Many elements of Christian theology, such as the resurrection, virgin birth, and atonement through sacrifice, have precedents in earlier mythologies, including Egyptian, Greek, and Roman religions.

If borrowing ideas from other traditions renders a worldview inferior or dependent, Christianity itself would fall into this category. Yet, apologists often ignore these parallels, selectively applying the borrowing argument to secular systems while exempting Christianity from the same scrutiny.


1. Undermining Intellectual Discourse

The borrowing argument frequently oversimplifies complex philosophical issues, reducing rich historical and cultural developments to a single theological explanation. For instance, principles like fairness and empathy, which are observable across a wide range of human societies and predate Christianity, are dismissed as merely derivative of Christian teachings. This diminishes the possibility of genuine intellectual engagement between competing worldviews.

2. Promoting Ideological Superiority

By claiming ownership of universal concepts, the borrowing argument promotes a hierarchical view of worldviews, with Christianity at the top. This rhetorical move can alienate individuals from other traditions, portraying them as ideologically inferior and dismissing their contributions to human intellectual progress.

3. Ignoring the Universality of Human Values

The borrowing argument often fails to acknowledge the universality of many of the values it claims are uniquely Christian. For instance, ideas about justice, human dignity, and compassion are found in diverse traditions, from ancient Greek philosophy to Confucianism and Buddhism. By insisting on Christian ownership, apologists disregard the shared human origins of these values, undermining the rich tapestry of global thought.


The claim that secularists borrow from Christianity is a rhetorically powerful but ultimately flawed argument. It overlooks the universality of human values, dismisses the contributions of other traditions, and simplifies the complex interplay of history, culture, and philosophy. Moreover, by its own logic, Christianity would be guilty of borrowing extensively from pre-Christian sources, undermining its claim to originality. While the argument serves the purpose of reinforcing faith and undermining competitors, it often comes at the expense of intellectual honesty and mutual respect. A more constructive approach would acknowledge the shared human heritage of values like justice, and compassion, fostering dialogue rather than division. By embracing this perspective, we can better appreciate the diverse sources of meaning that enrich our shared human experience.


To demonstrate the incoherence of the “borrowing” argument, we can analyze it using symbolic logic. The key claim made by Christian apologists is that when a worldview borrows concepts from another, it becomes inferior, incomplete, or untenable because it allegedly relies on a foundation it denies or fails to acknowledge. However, this claim, when applied consistently, backfires—Christianity itself would also be guilty of borrowing from earlier traditions (e.g., Greek philosophy, Stoicism, Judaism) and thus would fail by the same standards.

Below, we construct and analyze the logical framework underlying the borrowing argument to reveal its incoherence.


Variable Definitions

  • B(x, y): Worldview x borrows concepts from worldview y.
  • I(x): Worldview x is inferior, incomplete, or untenable.
  • C(x): Worldview x is coherent, complete, and tenable.
  • O(x): Worldview x is original and does not borrow from others.

  1. Borrowing and Inferiority:
    \forall x \forall y , (B(x, y) \to I(x))
    If worldview x borrows from worldview y, then x is inferior, incomplete, or untenable.
  2. Christianity Does Not Borrow:
    O(\text{Christianity})
    Christianity is original and does not borrow from other worldviews.
  3. Other Worldviews Borrow from Christianity:
    \forall x , (x \neq \text{Christianity} \to B(x, \text{Christianity}))
    All other worldviews borrow from Christianity.

1. Self-Defeating Nature of Premise 1

If “borrowing” renders a worldview inferior, then Christianity itself would be inferior due to its documented borrowing from Judaism, Greek philosophy, and Stoicism. For example:

  • Judaism: Christianity inherits monotheism, moral codes, and the concept of a covenant from Judaism.
  • Greek Philosophy: Christian theology integrates Platonism (the concept of the soul and the ideal realm) and Aristotelian logic (used extensively in Scholasticism).
  • Stoicism: The notion of universal brotherhood and natural law in Christianity parallels Stoic teachings.

Thus, if B(x, y) \to I(x), then B(\text{Christianity}, \text{Judaism}), B(\text{Christianity}, \text{Greek\ Philosophy}), and B(\text{Christianity}, \text{Stoicism}) imply I(\text{Christianity}).

2. Inconsistency in Borrowing Standards

If borrowing renders other worldviews inferior, then originality (O(x)) becomes a necessary condition for a worldview to be tenable (C(x)). Formally:

\forall x , (C(x) \to O(x)).

However, this premise would exclude Christianity, since it demonstrably borrows. By its own logic, Christianity cannot simultaneously be original (O(\text{Christianity})) and borrowing (B(\text{Christianity}, y)). This is logically inconsistent.

3. Universality of Borrowing

All worldviews, including Christianity, are built on earlier ideas. If borrowing universally leads to inferiority, then no worldview, including Christianity, can be coherent (C(x)). Formally:

\forall x , \exists y , (B(x, y)) \to \forall x , I(x).

This results in the conclusion that all worldviews are untenable, which is an absurd position.


  1. Assume \forall x \forall y , (B(x, y) \to I(x)).
    Borrowing renders a worldview inferior.
  2. Christianity borrows from Judaism, Greek philosophy, and Stoicism.
    B(\text{Christianity}, \text{Judaism}) \wedge B(\text{Christianity}, \text{Greek\ Philosophy}) \wedge B(\text{Christianity}, \text{Stoicism}).
  3. By premise (1), this implies:
    I(\text{Christianity}).
  4. But apologists claim C(\text{Christianity}): Christianity is coherent, complete, and tenable.
    C(\text{Christianity}) \wedge I(\text{Christianity}).
  5. This is a contradiction. Christianity cannot be both inferior and coherent simultaneously.
  6. Therefore, premise (1)—that borrowing renders a worldview inferior—must be false.

Instead of treating borrowing as a sign of inferiority, a more reasonable interpretation is that borrowing is a natural and inevitable part of human intellectual development. Ideas evolve over time, building on the insights and achievements of earlier traditions. For example:

  • Christianity builds on Judaism, incorporating its monotheism, moral teachings, and sacred texts.
  • The Enlightenment builds on Christianity, adapting ideas of equality and justice into a secular framework.
  • Modern secular ethics build on both religious and philosophical traditions, refining universal principles of human dignity and rights.

Borrowing, therefore, is not evidence of inferiority but of intellectual synthesis and progress.


The “borrowing” argument collapses under logical scrutiny. The claim that borrowing renders a worldview inferior, incomplete, or untenable is inconsistent when applied to Christianity itself, as Christianity borrows extensively from earlier traditions like Judaism and Greek philosophy. Symbolically, this leads to contradictions and undermines the argument’s validity. Rather than denigrating worldviews for borrowing, we should recognize borrowing as an essential feature of intellectual growth and cultural evolution. By embracing the universality of ideas, we foster dialogue, mutual respect, and shared understanding—values that transcend any one tradition.


In many Christian apologetic frameworks, especially those influenced by presuppositional thought, secular reasoning is often portrayed as “borrowing” from the Christian worldview. This rhetorical move attempts to undermine the legitimacy of non-Christian belief systems by suggesting that their use of logic, morality, or meaning depends—often unknowingly—on conceptual foundations laid by Christianity. According to this line of thought, rationality, moral norms, and coherent thought are only possible because the Christian God created the universe and the human mind. Therefore, when non-believers reason or affirm human dignity, they are allegedly standing on borrowed metaphysical ground.

But this argument becomes unstable when apologists retreat into a more theologically generous stance—claiming that such “borrowing” is actually evidence of God’s universal work in the world, often framed under the doctrine of common grace. On this view, God’s truth is dispersed throughout human cultures and histories, not exclusively within Christian circles. Insights from Confucius, Plato, Buddha, or Darwin can all be woven into God’s overarching providence. According to this softer framing, the cognitive and moral achievements of non-Christians are not illegitimate thefts from Christianity, but rather the unfolding of God’s truth across humanity.

From the perspective of a non-believer, however, this shift is not just theological—it is epistemically revealing. If Christian apologists are willing to treat non-Christian insights as valid expressions of God’s grace or providential design, then their entire critique of “borrowing” loses its force. It is no longer a meaningful accusation against secular thought. Instead, it becomes a kind of retrospective absorption—claiming credit for anything that aligns with Christian theology, regardless of origin.

This raises several problems:


If a Christian says, “Secular ethics only make sense because they unknowingly borrow from the Christian worldview,” they are making a philosophical critique—one that implies secular frameworks are incoherent without Christianity.

But if, when challenged, they say, “Well, God has spread His truth through all cultures; it’s common grace,” they have abandoned critique for theological assimilation. This is a conceptual retreat that transforms an objection into a rebranding: the very reasoning once condemned as parasitic is now interpreted as part of God’s design.

One cannot both accuse secularism of theft and then say the borrowed insights were gifted by divine benevolence. These are incompatible explanations. Either secular systems are conceptually incoherent and only function by borrowing illegitimately, or they are valid vehicles of general revelation. It cannot be both.


From the non-believer’s standpoint, the maneuver to reinterpret all intellectual success—even outside of Christian tradition—as part of “God’s plan” is not merely theologically self-serving. It’s unfalsifiable. No matter where insight arises—from Buddhist compassion to Stoic rationalism to Enlightenment humanism—the apologist can retroactively claim it was God’s doing. This means no conceivable counterexample can challenge the theological claim. But if a theory is structured so that it can accommodate every possible outcome, it loses explanatory power. It becomes immune to revision and therefore epistemically inert in any public, rational discourse.

Such a strategy is also indistinguishable in form from any other religious system making the same move. A Hindu could just as easily claim that all valid insight is the result of divine sparks scattered by Brahman. A Muslim might argue the same about Allah’s guidance. These are not competing arguments—they are narrative overlays applied post hoc. From a rational perspective, they are symmetrical in their explanatory impotence.


Ironically, if Christian apologists overextend divine providence to include all truth found anywhere, they risk diluting the very distinctiveness they seek to preserve. If every culture’s wisdom is already part of God’s plan, then Christianity becomes one voice among many in the divine choir. This universalizing approach may soften interreligious tensions, but it also makes the exclusivist claims of Christianity (e.g., “Jesus is the only way”) much harder to defend as epistemically privileged.

Apologists may try to navigate this by distinguishing between general revelation (truth scattered throughout the world) and special revelation (truth found in Christ and scripture). But if the general is sufficient to generate reason, morality, and meaning, then one must ask: What does special revelation actually add that is evidentially necessary? And if it is necessary, why do the general features appear to function so well without it?


Finally, it’s worth emphasizing that secular reasoning is not merely functional—it is coherently self-grounded. Logical principles, moral intuition, and scientific inquiry can be—and are—explained in terms of evolutionary development, cognitive psychology, and intersubjective human experience. These explanations may be imperfect, but they are naturalistic, testable, and improvable. They do not require the postulation of a deity to remain operational or intelligible.

Therefore, even if the Christian God existed, it would still be the case that secular reasoning works on its own terms. The claim that reason “presupposes” the Christian worldview is not supported by either historical usage or current functionality. Cultures long predating Christianity reasoned with sophistication, developed ethics, and built complex societies—often without any contact with Christian doctrine. From a secular standpoint, this is not a mystery needing a theological explanation. It is simply evidence that reason and moral awareness are human, not theological phenomena.


If Christian apologists wish to treat the successes of secular reasoning as part of God’s universal activity, they are welcome to that theological interpretation. But they must then abandon the claim that secular worldviews are incoherent without Christianity. One cannot simultaneously dismiss secularism as conceptually bankrupt and absorb its achievements as providential.

From the perspective of the non-believer, this double move reveals not the superiority of Christian epistemology, but rather its elasticity—its ability to claim credit in all scenarios while never accepting disconfirmation. In contrast, secular reasoning remains tethered to standards that demand coherence, evidence, and proportionality. It may lack divine backing, but it also avoids special pleading—and that, in itself, is a virtue worth defending.
