Christian Response to Secular Humanism

Secular humanism is more coherent than agnosticism or atheism considered as bare epistemic postures. Where atheism merely denies God and agnosticism suspends judgment, secular humanism builds a positive program — an account of knowledge, ethics, and human flourishing that does not require a deity. The clearest summary remains the affirmations of Humanism and Its Aspirations (Humanist Manifesto III, 2003).

Knowledge of the world is derived by observation, experimentation, and rational analysis. Manifesto III states: "Knowledge of the world is derived by observation, experimentation, and rational analysis." Scientific method is treated not merely as one source of knowledge among others but as the privileged route to reliable belief about reality.

Humans are an integral part of nature, the result of unguided evolutionary change. The Manifesto rejects any teleological or supernatural account of human origins. Human beings are continuous with the rest of the biological world; what makes them special is their capacity for reason, language, ethics, and culture — capacities themselves explained naturalistically.

Ethical values are derived from human need and interest as tested by experience. Morality is built up empirically: from study of what does and does not promote human well-being. The pioneering project of Sam Harris's The Moral Landscape (2010) — to ground ethics in the empirically measurable facts of conscious well-being — is one prominent recent attempt to flesh out this claim.

Life's fulfillment emerges from individual participation in the service of humane ideals. Meaning is not imposed from above; it is constructed through participation — work, relationships, art, justice, the pursuit of truth. Manifesto III: "Life's fulfillment emerges from individual participation in the service of humane ideals."

Humans are social by nature and find meaning in relationships. The Manifesto stresses community: humans flourish in connection, not isolation. This frames secular humanist accounts of family, friendship, civic life, and cosmopolitan solidarity.

Working to benefit society maximizes individual happiness. A broadly utilitarian and humanitarian framing: the good of the individual and the good of the community are aligned. Greg Epstein's Good Without God (2009) is essentially an extended argument for this affirmation, addressed to a non-religious American audience.

Beyond the affirmations, three negative commitments are constant:

• Naturalism — there is nothing beyond nature; "supernatural" is either an empty term or a label for the not-yet-explained.
• Anti-clericalism, not anti-religion — many humanists are sympathetic to the cultural and ethical contributions of religious traditions while opposing institutional religious authority over public life.
• Progressivism — moral and social progress is real, has been demonstrated historically, and can be extended through reason and reform.

Secular humanism's affirmations are stated positively: human dignity, reason, ethics, and flourishing without theism. The sections that follow examine how those affirmations land on the central questions every worldview must answer — God, Christ, sin, salvation, sacred authority — and where they sit in relation to the witness of Scripture. The aim is not to dismiss what humanism cares about. The aim is to ask whether the humanist worldview can ground what it most affirms.

Secular humanism is, by definition, "without theism." The American Humanist Association's signature phrase — "a progressive philosophy of life that, without theism or other supernatural beliefs" — places the rejection of God at the center of the movement's self-understanding. Under that umbrella, individual humanists distribute across a range of postures: some are philosophically committed atheists, some functional agnostics, some "spiritual but not religious" in a non-theistic sense.

What unites them is not a shared metaphysics of denial but a shared anthropocentrism: human flourishing is the goal, not divine glory. Whatever one says about whether God exists in the abstract, the practical orientation of secular humanism is to act as if questions of God need not be answered to live well. The Center for Inquiry, which now houses the Council for Secular Humanism, frames its mission around science, secularism, and humanist values without engaging theological metaphysics as such.

Paul Kurtz developed the concept of eupraxsophy — "good practical wisdom" — explicitly as a religion-substitute. The intent was to give secular humanism the cultural functions religion has historically performed (rites of passage, communal moral formation, frameworks for grief, marriage, parenting, dying) without supernatural commitments. Greg Epstein's Good Without God and the network of humanist chaplaincies on American university campuses are heirs of that project: an attempt to provide religion's social goods without religion's theological claims.

The biblical witness directly addresses this stance.

“because what may be known of God is manifest in them, for God has shown it to them. For since the creation of the world His invisible attributes are clearly seen, being understood by the things that are made, even His eternal power and Godhead, so that they are without excuse,”

— "what may be known of God is manifest in them, for God has shown it to them. For since the creation of the world His invisible attributes are clearly seen, being understood by the things that are made, even His eternal power and Godhead, so that they are without excuse." General revelation is the claim that God has not been silent — that creation itself testifies to its Creator. The humanist who finds the universe rationally ordered, who marvels at the structure of matter, who is awed by the moral seriousness of the human conscience, is, on the biblical analysis, already perceiving what Romans describes.

“God, who made the world and everything in it, since He is Lord of heaven and earth, does not dwell in temples made with hands. Nor is He worshiped with men's hands, as though He needed anything, since He gives to all life, breath, and all things. And He has made from one blood every nation of men to dwell on all the face of the earth, and has determined their preappointed times and the boundaries of their dwellings, so that they should seek the Lord, in the hope that they might grope for Him and find Him, though He is not far from each one of us; for in Him we live and move and have our being, as also some of your own poets have said, "For we are also His offspring." Therefore, since we are the offspring of God, we ought not to think that the Divine Nature is like gold or silver or stone, something shaped by art and man's devising. Truly, these times of ignorance God overlooked, but now commands all men everywhere to repent, because He has appointed a day on which He will judge the world in righteousness by the Man whom He has ordained. He has given assurance of this to all by raising Him from the dead.”

— Paul's address to the philosophical humanists of his own day at the Areopagus is striking for what it does and does not do. Paul does not begin with denunciation. He begins by noting that the Athenian altar to the unknown god is a kind of partial truth. He affirms that humans live, move, and have their being in God, that "we are also His offspring," that God "has made from one blood every nation of men." Then he names the resurrection as the public assurance that universal accountability is real. The form of his engagement with educated, reason-respecting non-theists is the model for Christian engagement with secular humanism.

Secular humanists generally treat Jesus of Nazareth as a historical figure of considerable ethical weight. The mythicist position — that Jesus never existed — is rare among serious historians and is not the mainstream humanist view. What humanism rejects is not the man but the supernatural framing: the divinity, the miracles, the resurrection.

The classic humanist reading is the "great moral teacher" approach. Jesus' ethical teaching — the Sermon on the Mount, the parables, the radical love-of-neighbor — is admired and frequently invoked. Thomas Jefferson's editing of the New Testament to remove all supernatural elements while retaining Jesus' moral instruction (the so-called Jefferson Bible, 1820) is an early American expression of this approach. A.C. Grayling and other contemporary humanists treat Jesus' ethics as one stream within a broader humanist tradition that includes Confucius, the Stoics, and the Enlightenment moralists.

The Jesus Seminar (founded 1985 by Robert Funk, with John Dominic Crossan as a leading voice) institutionalized humanist methodology applied to gospel texts. The Seminar's color-coded votes on the authenticity of Jesus' sayings — red for "Jesus probably said this," black for "this is from later tradition" — produced a Jesus largely stripped of supernatural claims and apocalyptic teaching, recast as an itinerant Cynic-style sage. Conservative scholars (N.T. Wright, Craig Evans, Ben Witherington) have extensively critiqued the Seminar's methodology, but its influence on popular humanist images of Jesus remains significant.

The biblical Jesus, on close reading, does not fit the "great moral teacher" frame. C.S. Lewis's trilemma applies directly: the Jesus of the gospels claimed to forgive sins (Mark 2), claimed identity with the "I AM" of Exodus 3 (John 8:58), accepted worship (Matthew 14:33), and predicted His own resurrection (Mark 8:31).

“Jesus said to him, "I am the way, the truth, and the life. No one comes to the Father except through Me."”

— "I am the way, the truth, and the life. No one comes to the Father except through Me." A merely great moral teacher does not make this claim. Either Jesus was who He claimed to be, or He was deluded, or He was a deliberate deceiver. The humanist option Lewis identifies as unavailable is precisely the "humanist Jesus" — wise teacher, kind person, no divine claims to bother with.

The historical case for the resurrection — and therefore for the divine identity Jesus claimed — rests on multiple converging lines: the empty tomb attested first by women (an embarrassing detail unlikely to be invented in a patriarchal culture), the rapid emergence of resurrection belief among Jewish monotheists (for whom bodily resurrection of one individual before the end of history was theologically unprecedented), the conversion of skeptics including James and Paul, and the early creed of

“For I delivered to you first of all that which I also received: that Christ died for our sins according to the Scriptures, and that He was buried, and that He rose again the third day according to the Scriptures,”

— dated by Pauline scholars to within five years of the crucifixion. The humanist who admires Jesus' ethics is invited to engage the historical question of who He actually claimed to be.

Secular humanism does not operate with a category of sin in the biblical sense. There is no offense against God because, for the humanist, there is no God to be offended. Wrongdoing is reconceived in entirely horizontal terms: harm to others, ignorance, immaturity, structural injustice, the failure of empathy. Where Scripture frames moral failure as transgression of the holy God's character and command, humanism frames it as friction between human interests or a mismatch between behavior and well-being.

The remedy, on the humanist account, is education, accountability, therapy, social reform, and the patient extension of moral progress. There is no guilt that requires atonement; there is no holiness that requires propitiation. Greg Epstein's Good Without God presents this constructively: people fail one another, but the work of moral life is repair, restitution, and learning, not the resolution of a metaphysical accounts.

A notable feature of contemporary humanism is its strong tendency toward moral realism without theistic grounding. Most secular humanists hold that some things are genuinely wrong — the Holocaust was not merely disapproved of, slavery was not merely culturally local, child abuse is not a matter of taste. Sam Harris's The Moral Landscape (2010) is the most ambitious recent attempt to ground these intuitions empirically: morality, Harris argues, can be grounded in the facts of conscious well-being, with science as the arbiter. Other humanists rely on contractualism (Scanlon, Rawls), virtue theory (MacIntyre, in his pre-Catholic phase), or simply on widely-shared moral intuitions taken as basic.

The biblical analysis takes humanist moral realism seriously. If moral facts are objective — if cruelty is really wrong, not just unfashionable — then they require an objective standard outside human preference and cultural convention.

“for when Gentiles, who do not have the law, by nature do the things in the law, these, although not having the law, are a law to themselves, who show the work of the law written in their hearts, their conscience also bearing witness, and between themselves their thoughts accusing or else excusing them”

— "for when Gentiles, who do not have the law, by nature do the things in the law, these, although not having the law, are a law to themselves, who show the work of the law written in their hearts, their conscience also bearing witness." Paul's claim is that the moral law is written on every human heart by the God who made human beings. The humanist who appeals to deep moral intuition as evidence of objective moral truth is, on this reading, appealing to precisely what Romans 2 describes — without acknowledging the God whose handwriting it is.

The Christian diagnosis is wider.

“As it is written: "There is none righteous, no, not one; There is none who understands; There is none who seeks after God. They have all turned aside; They have together become unprofitable; There is none who does good, no, not one."”

— "There is none righteous, no, not one... There is none who does good, no, not one." This is not a claim that humanists are bad people. It is a claim that the standard against which any human life is measured is not "better than average" but the holy character of God Himself. Against that standard, all of us — humanist, theist, agnostic — fall short. The remedy is not more education or better social structures, though those have their place. The remedy is the gift of God in Christ Jesus.

There is no salvation in secular humanism in the transcendent sense. There is nothing to be saved from beyond the harms human beings inflict on one another and the difficulties of mortal life, and there is no one to do the saving beyond ourselves and our communities. The humanist goal is human flourishing in this life — Greg Epstein's "good life" without God, Manifesto III's "individual participation in the service of humane ideals."

The good life is constructed: through love, work, beauty, friendship, justice, and contribution to the human community. Ronald Dworkin's Religion Without God (2013) articulates an influential adjacent position: one can hold convictions about the importance of human life and the reality of moral value with a quasi-religious seriousness while denying any personal God. The texture of the humanist good life is neither hedonistic nor stoic; it tends toward serious engagement with art, family, civic life, and the moral seriousness of the human predicament.

Death is final. Humanist Manifesto II is direct: "the soul has no demonstrated existence." When a person dies, they cease to exist as a conscious subject. Memory, legacy, contribution to ongoing human projects — these are the only forms of persistence. Some humanists embrace these unflinchingly; others, particularly in the transhumanist wing of the broader movement, look to cryonics, mind-uploading, and life-extension technology as material extensions of life. The transhumanist program is consistent with humanist materialism: if death is the cessation of a physical pattern, technology that preserves the pattern preserves the person.

The biblical witness gives a different account on every point.

“For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.”

— "For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord." Death, on the biblical reading, is neither a natural neutral nor a problem to be solved by technology. It is the wage of sin — and the gift offered against it is not extension of biological life but eternal life in Christ.

“Let us hear the conclusion of the whole matter: Fear God and keep His commandments, For this is man's all. For God will bring every work into judgment, Including every secret thing, Whether good or evil.”

— "Fear God and keep His commandments, for this is man's all. For God will bring every work into judgment, including every secret thing, whether good or evil." The Preacher's conclusion, after surveying every secular alternative, is that the meaning of human life is finally bound to the God who made and judges it.

“For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast.”

— salvation is by grace through faith, "not of works, lest anyone should boast." This is the precise opposite of every "good without God" framing. The humanist, building meaning by individual participation in humane ideals, is constructing a ladder. The gospel announces that the ladder is unnecessary because the gift has already been given. The honest seeker is invited to receive what cannot be earned.

Secular humanism has no sacred texts. As an explicitly non-religious worldview, it disclaims any document with the kind of binding authority Scripture has within Christianity, the Qur'an within Islam, or the Tanakh within Judaism. Its foundational documents are descriptive and aspirational rather than authoritative — programmatic statements rather than revelations.

The three Humanist Manifestos are the closest thing to canonical texts. Humanist Manifesto I (1933), drafted by Roy Wood Sellars and signed by 34 American intellectuals including John Dewey, framed humanism as a non-supernatural religious alternative for an industrial age. Humanist Manifesto II (1973), drafted by Paul Kurtz and Edwin Wilson, was sharper and more political — addressing the Vietnam war, civil rights, environmental crisis, and the failure of traditional religion to address modern problems. Humanist Manifesto III — Humanism and Its Aspirations (American Humanist Association, 2003) — is shorter, more affirmative, and led by positive commitments rather than rejections of theism.

Periodicals. Free Inquiry, founded by Paul Kurtz in 1980, remains the journal of the Council for Secular Humanism. The Humanist, published by the American Humanist Association, is the older and broader-circulation magazine. Skeptical Inquirer, also founded by Kurtz, addresses paranormal and pseudoscientific claims from a humanist-naturalist standpoint.

Books that have shaped the movement. Paul Kurtz, In Defense of Secular Humanism (1983) and Forbidden Fruit: The Ethics of Secularism (1988); A.C. Grayling, The God Argument: The Case Against Religion and for Humanism (2013) and The Good Book: A Humanist Bible (2011, an anthology of secular wisdom literature edited in biblical chapter-and-verse format); Greg Epstein, Good Without God: What a Billion Nonreligious People Do Believe (2009); Sam Harris, The Moral Landscape (2010); Ronald Dworkin, Religion Without God (2013); Susan Jacoby, Freethinkers: A History of American Secularism (2004).

Older sources frequently cited as antecedents. John Dewey, A Common Faith (1934), articulated a non-supernatural conception of religious experience that influenced both Manifestos. The classical empiricist tradition — David Hume, An Enquiry Concerning Human Understanding (1748) — supplies the philosophical critique of miracle and supernatural claim. The Enlightenment tradition broadly — Voltaire, Diderot, the Encyclopédistes — is treated as humanism's deep historical lineage.

What unites these documents is a posture rather than a doctrinal authority. None of them claims revelation. None demands assent on pain of damnation. They describe and recommend; they do not command. This is, in the humanist self-understanding, a virtue: humanism does not seek the kind of authority religion claims and so does not need texts that exercise it.

God Is Known Through Creation — General Revelation

“because what may be known of God is manifest in them, for God has shown it to them. For since the creation of the world His invisible attributes are clearly seen, being understood by the things that are made, even His eternal power and Godhead, so that they are without excuse,”

— "because what may be known of God is manifest in them, for God has shown it to them. For since the creation of the world His invisible attributes are clearly seen, being understood by the things that are made, even His eternal power and Godhead, so that they are without excuse." The order, beauty, and intelligibility of the universe — the very features the humanist most admires — are presented as a witness to the Creator that no honest observer is ultimately exempt from.

The Moral Law Is Written on the Human Heart

“for when Gentiles, who do not have the law, by nature do the things in the law, these, although not having the law, are a law to themselves, who show the work of the law written in their hearts, their conscience also bearing witness, and between themselves their thoughts accusing or else excusing them”

— "for when Gentiles, who do not have the law, by nature do the things in the law, these, although not having the law, are a law to themselves, who show the work of the law written in their hearts, their conscience also bearing witness, and between themselves their thoughts accusing or else excusing them." This is the verse the humanist conscience most directly engages. The moral realism humanists affirm is, on Paul's account, evidence of the law God has written in every person — including those without explicit revelation. The humanist's moral seriousness is testimony to the source the worldview disclaims.

Human Dignity Is Grounded in the Image of God

“Then God said, "Let Us make man in Our image, according to Our likeness; let them have dominion over the fish of the sea, over the birds of the air, and over the cattle, over all the earth and over every creeping thing that creeps on the earth." So God created man in His own image; in the image of God He created him; male and female He created them.”

— "Then God said, 'Let Us make man in Our image, according to Our likeness... So God created man in His own image; in the image of God He created him; male and female He created them.'" The dignity humanism affirms but cannot ground is, on the biblical account, the dignity of an image-bearer of the Creator. Humans matter not because evolution produced them but because God made them in His own image.

The Diagnosis of Universal Need

“As it is written: "There is none righteous, no, not one; There is none who understands; There is none who seeks after God. They have all turned aside; They have together become unprofitable; There is none who does good, no, not one."”

— "There is none righteous, no, not one; There is none who understands; There is none who seeks after God. They have all turned aside; They have together become unprofitable; There is none who does good, no, not one." Scripture's diagnosis is universal — the Manifestos' confidence in human moral progress meets a sober biblical assessment of the persistent fact of human evil.

The Wisdom of the World Is Not Enough

“Where is the wise? Where is the scribe? Where is the disputer of this age? Has not God made foolish the wisdom of this world? For since, in the wisdom of God, the world through wisdom did not know God, it pleased God through the foolishness of the message preached to save those who believe.”

— "Where is the wise? Where is the scribe? Where is the disputer of this age? Has not God made foolish the wisdom of this world? For since, in the wisdom of God, the world through wisdom did not know God, it pleased God through the foolishness of the message preached to save those who believe." Paul does not denigrate human reason; he denies that human reason is finally sufficient for the question that matters most. The humanist's confidence in reason as the privileged route to the truth that sets free is gently but firmly displaced by the foolishness of the gospel.

The Whole Duty of Man

“Let us hear the conclusion of the whole matter: Fear God and keep His commandments, For this is man's all. For God will bring every work into judgment, Including every secret thing, Whether good or evil.”

— "Let us hear the conclusion of the whole matter: Fear God and keep His commandments, For this is man's all. For God will bring every work into judgment, Including every secret thing, Whether good or evil." The Preacher of Ecclesiastes has surveyed every secular alternative — pleasure, work, wisdom, wealth, fame — and pronounces them "vanity of vanities" without God. His final word is that human meaning is bound to the God who made and judges human life.

Scripture's Reasoning with the Philosophical Humanists of Paul's Day

“God, who made the world and everything in it, since He is Lord of heaven and earth, does not dwell in temples made with hands. Nor is He worshiped with men's hands, as though He needed anything, since He gives to all life, breath, and all things. And He has made from one blood every nation of men to dwell on all the face of the earth, and has determined their preappointed times and the boundaries of their dwellings, so that they should seek the Lord, in the hope that they might grope for Him and find Him, though He is not far from each one of us; for in Him we live and move and have our being, as also some of your own poets have said, "For we are also His offspring." Therefore, since we are the offspring of God, we ought not to think that the Divine Nature is like gold or silver or stone, something shaped by art and man's devising. Truly, these times of ignorance God overlooked, but now commands all men everywhere to repent, because He has appointed a day on which He will judge the world in righteousness by the Man whom He has ordained. He has given assurance of this to all by raising Him from the dead.”

— "God, who made the world and everything in it... has made from one blood every nation of men to dwell on all the face of the earth... so that they should seek the Lord, in the hope that they might grope for Him and find Him, though He is not far from each one of us; for in Him we live and move and have our being... He has appointed a day on which He will judge the world in righteousness by the Man whom He has ordained. He has given assurance of this to all by raising Him from the dead." Paul's address to the Areopagus — to the philosophers of his own day — is the New Testament's clearest model for engagement with educated, reason-respecting non-theists.

The Hope That Suffering Is Not the Final Word

“For I consider that the sufferings of this present time are not worthy to be compared with the glory which shall be revealed in us. For the earnest expectation of the creation eagerly waits for the revealing of the sons of God. For the creation was subjected to futility, not willingly, but because of Him who subjected it in hope; because the creation itself also will be delivered from the bondage of corruption into the glorious liberty of the children of God. For we know that the whole creation groans and labors with birth pangs together until now. Not only that, but we also who have the firstfruits of the Spirit, even we ourselves groan within ourselves, eagerly waiting for the adoption, the redemption of our body. For we were saved in this hope, but hope that is seen is not hope; for why does one still hope for what he sees? But if we hope for what we do not see, we eagerly wait for it with perseverance.”

— "For I consider that the sufferings of this present time are not worthy to be compared with the glory which shall be revealed in us. For the earnest expectation of the creation eagerly waits for the revealing of the sons of God... because the creation itself also will be delivered from the bondage of corruption into the glorious liberty of the children of God." Where humanism appeals to "progress" without telos, Romans 8 announces a creation moving toward redemption — a future the humanist project cannot supply on its own terms.

Universal Need and the Gift Offered

“for all have sinned and fall short of the glory of God,”

— "for all have sinned and fall short of the glory of God."

“For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.”

— "For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord."

“But God demonstrates His own love toward us, in that while we were still sinners, Christ died for us.”

— "But God demonstrates His own love toward us, in that while we were still sinners, Christ died for us."

“Jesus said to him, "I am the way, the truth, and the life. No one comes to the Father except through Me."”

— "I am the way, the truth, and the life. No one comes to the Father except through Me."

“For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast.”

— "For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast."

“that if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved.”

— "that if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved."

The table below compares the secular humanist worldview with the Christian witness of Scripture across the central questions every worldview must answer. The contrast is not between concern and indifference — both Christianity and humanism are deeply serious about human dignity, ethics, and the human future. The contrast is over where these concerns are grounded. Christianity's answers all flow from the existence of a personal God who made human beings in His image and entered history in His Son. Humanism's answers all begin with the affirmation of human worth abstracted from any transcendent source. Where the two part company is not over what to value, in many cases, but over how to ground what we value.

1. The Grounding Problem — Borrowed Capital

Secular humanism affirms objective moral truths — the wrongness of cruelty, the reality of human dignity, the demands of justice — while denying the only worldview that has historically grounded such truths. C.S. Lewis put the point sharply in Mere Christianity: "If there was a controlling power outside the universe, it could not show itself to us as one of the facts inside the universe... The only way in which we could expect it to show itself would be inside ourselves as an influence or a command trying to get us to behave in a certain way."

The humanist who insists that the Holocaust was genuinely wrong, not merely culturally disapproved of, is making a claim that requires explanation. Why would unguided evolutionary processes produce moral facts that bind every rational agent? On naturalism, evolution selects for behaviors that promote survival and reproduction — not for the perception of objective moral truth. Sam Harris's Moral Landscape attempts to ground morality in well-being, but the move from "this behavior maximizes well-being" to "everyone is obligated to maximize well-being" is precisely the gap that requires more than naturalism can supply.

“for when Gentiles, who do not have the law, by nature do the things in the law, these, although not having the law, are a law to themselves, who show the work of the law written in their hearts, their conscience also bearing witness, and between themselves their thoughts accusing or else excusing them”

— the moral law written on the human heart by the God who made human beings is the explanation Christianity offers for the very intuitions humanism affirms. Alvin Plantinga and William Lane Craig argue that the best explanation for the objectivity of moral facts is a personal, perfectly good God whose character is the moral standard. The humanist conscience, on this analysis, is a witness against the worldview that disclaims its source.

2. The Dignity Problem — Why Humans Matter

The Manifestos affirm human dignity as a fundamental value. But on the worldview the Manifestos also affirm — humans as "the result of unguided evolutionary change" — what makes human dignity a fact rather than a poetic projection? If a human being is matter in motion, the same kind of stuff as a rock arranged differently, why does a human's flourishing matter more than the integrity of a rock?

“Then God said, "Let Us make man in Our image, according to Our likeness; let them have dominion over the fish of the sea, over the birds of the air, and over the cattle, over all the earth and over every creeping thing that creeps on the earth." So God created man in His own image; in the image of God He created him; male and female He created them.”

— "So God created man in His own image; in the image of God He created him; male and female He created them." Christianity's answer to the dignity question is direct: human beings matter because they bear the image of the God who made them. Their dignity is not a cultural achievement or a useful fiction. It is an ontological fact, grounded in their creation by a personal Creator.

The humanist who affirms human dignity is, on the Christian analysis, borrowing from a Christian metaphysic — affirming the conclusion (humans matter) while rejecting the premise (a Creator who made them in His image) that makes the conclusion intelligible. Friedrich Nietzsche, more than most secular humanists, understood this clearly: the death of God removes not only theology but also the cluster of values theology was holding up. Nietzsche's call for a "transvaluation of all values" was an attempt to invent a non-Christian foundation for what had previously been Christian ethics. Most secular humanists are working with what Nietzsche would call "borrowed capital" — Christian ethical conclusions on a non-Christian metaphysical balance sheet.

3. The Progress Problem — Progress Toward What?

Manifesto III appeals repeatedly to "progress" — moral progress, social progress, the extension of justice and dignity. But progress is a directional concept; it requires a goal. To say a society has "progressed" requires a standard against which earlier and later states can be measured. Without a telos — without an account of what human life is for — change is only change, not progress.

“For I consider that the sufferings of this present time are not worthy to be compared with the glory which shall be revealed in us. For the earnest expectation of the creation eagerly waits for the revealing of the sons of God. For the creation was subjected to futility, not willingly, but because of Him who subjected it in hope; because the creation itself also will be delivered from the bondage of corruption into the glorious liberty of the children of God. For we know that the whole creation groans and labors with birth pangs together until now. Not only that, but we also who have the firstfruits of the Spirit, even we ourselves groan within ourselves, eagerly waiting for the adoption, the redemption of our body. For we were saved in this hope, but hope that is seen is not hope; for why does one still hope for what he sees? But if we hope for what we do not see, we eagerly wait for it with perseverance.”

— Paul's vision of creation "delivered from the bondage of corruption into the glorious liberty of the children of God" supplies the kind of telos progress requires. There is a direction to the story — toward redemption, toward the unveiling of the children of God, toward the renewal of creation. The Christian story can speak coherently of progress because it has a destination.

Secular humanism faces a recurring difficulty here. The Enlightenment confidence in moral progress collided in the twentieth century with the Holocaust, the Gulag, and the killing fields — all secular projects, all justified in the name of human flourishing as their architects understood it. Manifesto II concedes the difficulty: "We are responsible for what we are or will be." The concession is honest, but it does not solve the problem: what makes the humanist's vision of human flourishing the right one, and the architects of twentieth-century totalitarianism wrong, given that all parties were appealing to human values without transcendent reference? The question is not whether humanists today are good people — many obviously are. The question is whether humanism as a worldview supplies the standards by which one humanism (the AHA's) is correct and another (e.g., Comte's positivist religion of humanity, or Soviet "scientific socialism") was wrong.

4. The Hope Problem — The Twentieth Century

The most theologically serious historical question for secular humanism concerns the twentieth century. The Manifestos are documents of optimism. Manifesto I (1933) speaks of humanity "entering upon a new and richer experience." Manifesto III (2003) speaks of "individual participation in the service of humane ideals" producing fulfillment. Yet the century that ran between Manifestos I and III — the most thoroughly secular century in human history, the one in which Christian metaphysics most loudly declared dead — produced unprecedented mass killing.

This is not a debater's point. It is a question the humanist program must address. If human nature is what humanism says it is — fundamentally good, capable of moral self-direction, requiring only education and good institutions to flourish — why does the historical record of secularism's most thorough trial conflict so directly with the humanist anthropology? The Christian answer is that human beings are simultaneously image-bearers of God (and so bear real dignity) and fallen creatures (and so are not the simple moral agents humanism imagines).

“As it is written: "There is none righteous, no, not one; There is none who understands; There is none who seeks after God. They have all turned aside; They have together become unprofitable; There is none who does good, no, not one."”

is harder than humanist anthropology — and it fits the historical evidence more closely.

5. The Authority Problem — Reason on Naturalism

Humanism privileges reason as the route to reliable belief about reality. But on humanism's own naturalist commitments, human reason is itself a product of unguided evolutionary processes — selected for survival value, not for truth-tracking. Alvin Plantinga's evolutionary argument against naturalism (Where the Conflict Really Lies, 2011) develops the point: if our cognitive faculties evolved purely for adaptive fitness, the probability that they reliably track truth — including the metaphysical truth of naturalism itself — is low or inscrutable. Naturalism cannot easily ground confidence in the very reasoning by which naturalism is affirmed.

Christianity supplies a different account. Human reason, on the biblical view, is part of what it means to bear the image of a rational God; it is reliable (within proper limits) because it was designed by the God whose nature is truth. The humanist confidence in reason makes more sense within a theistic worldview than within the naturalist worldview the humanist also affirms.

“God, who made the world and everything in it, since He is Lord of heaven and earth, does not dwell in temples made with hands. Nor is He worshiped with men's hands, as though He needed anything, since He gives to all life, breath, and all things. And He has made from one blood every nation of men to dwell on all the face of the earth, and has determined their preappointed times and the boundaries of their dwellings, so that they should seek the Lord, in the hope that they might grope for Him and find Him, though He is not far from each one of us; for in Him we live and move and have our being, as also some of your own poets have said, "For we are also His offspring." Therefore, since we are the offspring of God, we ought not to think that the Divine Nature is like gold or silver or stone, something shaped by art and man's devising. Truly, these times of ignorance God overlooked, but now commands all men everywhere to repent, because He has appointed a day on which He will judge the world in righteousness by the Man whom He has ordained. He has given assurance of this to all by raising Him from the dead.”

— Paul's address at the Areopagus is the New Testament's model for engagement with sophisticated, reason-respecting non-theists. Paul does not denounce the philosophers. He reasons with them, citing their poets, building on their partial truths, and bringing them to the resurrection — the public assurance of universal accountability that grounds the call to repentance. The Christian engagement with secular humanism follows this pattern: take the humanist's seriousness seriously, affirm what the worldview gets right about human dignity and ethics, and invite an honest examination of where those affirmations are most coherently grounded.

If you are reading this as someone who has built a serious, considered life on humanist convictions — who cares about justice, who insists on evidence, who refuses cheap religious comfort and shallow moralism — this section is written for you. The previous sections have made the case as honestly as space allows. What follows is a direct invitation, addressed to you in the second person.

The longing you carry — for justice that is real and not merely fashionable, for human beings to matter in a way that does not reduce to chemistry, for moral progress that goes somewhere rather than simply changes — that longing is itself testimony. Scripture says it comes from somewhere: from being made in the image of a God who is Himself just, who Himself loves, who Himself is the source of every value humanism affirms. The question this article has pressed is whether the affirmations you most care about can be coherently grounded inside a worldview that disclaims their source.

“for all have sinned and fall short of the glory of God,”

— "for all have sinned and fall short of the glory of God." This is not the verdict of an external judge against people who have done their best. It is a plain account of the moral situation every honest person already knows in their own conscience. The humanist who insists on being held to a high standard — who refuses the easy out of relativism — is closer to this verse than they may realize.

“For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.”

— "For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord." There is a wage, and there is a gift. The humanist program offers many goods: meaningful work, community, ethical seriousness, the courage to face mortality without illusion. What it cannot offer is what this verse offers: eternal life as a gift, not earned by any quality of the recipient.

“But God demonstrates His own love toward us, in that while we were still sinners, Christ died for us.”

— "But God demonstrates His own love toward us, in that while we were still sinners, Christ died for us." Notice what this verse does not say. It does not say that God loved the worthy. It does not say He loved those who first cleaned themselves up morally. It says that He demonstrated love toward us while we were still sinners. The gospel is not an ethics of self-improvement, which is at least closer to humanism. It is the announcement that God acted for the unworthy.

“Jesus said to him, "I am the way, the truth, and the life. No one comes to the Father except through Me."”

— "I am the way, the truth, and the life. No one comes to the Father except through Me." The humanist Jesus — kindly teacher, occasional ethicist, no metaphysical claims — is not the Jesus of the gospels. The Jesus of the gospels claimed to be the way, the truth, and the life. Either the claim is true or it is not. C.S. Lewis's trilemma still applies: a man who said this was either who He claimed to be, or He was deluded, or He was a deliberate deceiver. The humanist option that allows you to keep Him as a great moral teacher while ignoring the claim He made about Himself is the option the texts do not allow.

“For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast.”

— "For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast." This is the precise opposite of every "good without God" framing. Salvation is not the reward for moral seriousness, however admirable. It is a gift, given to those who receive it through faith.

“that if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved.”

— "that if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved." The hinge is a historical claim. Examine the historical case for the resurrection — not the caricature, but the actual case made by historians from N.T. Wright to William Lane Craig. Bring your humanist demand for evidence to that question. Then bring whatever conclusion you reach to Christ.

The humanist longing for justice, for dignity, for moral progress, for human beings to matter — these are not illusions. Scripture says they are exactly right. They come from being made in the image of God, fallen, and redeemable in Christ. The God who made you in His image is not a competitor to your seriousness about being human. He is the source of it.

Secular humanism gets a great deal right. It is serious about human suffering. It refuses cheap religious answers that paper over real evil. It insists on examining the world honestly, on weighing evidence, on building communities of moral concern that do not depend on tribal loyalty or supernatural sanction. Christianity should be quick to affirm these instincts where it finds them. Many humanists are among the most morally serious people in any room — refusing to look away from injustice, refusing to settle for easy comfort, refusing the kinds of religious certainty that have done genuine damage in history.

The question this article has pressed is whether the foundations humanism offers can in fact bear what humanism most affirms. Human dignity, objective moral truth, the reality of progress, the trustworthiness of reason itself — these are convictions Christianity also holds. Christianity claims to ground them: in a Creator who made human beings in His image, who wrote His moral law on every human heart, who entered history in His Son, who promises a future in which creation itself is renewed. The humanist worldview affirms the conclusions while disclaiming the premises. The Christian invitation is not to abandon humanism's seriousness but to follow it through to the foundation that holds it up.

The gospel does not require you to give up your moral seriousness, your love of evidence, or your concern for human flourishing. It claims to give all of those a deeper foundation than naturalism can supply.

“Jesus said to him, "I am the way, the truth, and the life. No one comes to the Father except through Me."”

— Jesus does not present Himself as one teacher among many in a humanist anthology. He presents Himself as the way, the truth, and the life. The invitation is to consider, honestly, whether He is who He said He was — and to bring whatever you find to Him.

Read the Gospel of John alongside The God Argument. Read N.T. Wright on the resurrection alongside the Jesus Seminar's reconstructions. Examine the historical evidence with the same honesty you bring to other questions. And then, with the prayer of the desperate father in

“Immediately the father of the child cried out and said with tears, "Lord, I believe; help my unbelief!"”

, bring whatever faith or doubt you have to the God who has revealed Himself in creation, in conscience, in Scripture, and finally in His Son. He is not afraid of your honest questions. He invites them.
