What is secular humanism?

Secular humanism is a philosophy and worldview that affirms human reason, science, and shared ethical values as the sole reliable guides for living, explicitly rejecting reliance on divine revelation, religious authority, or the supernatural. It grew out of Enlightenment confidence in human rationality and gained formal organizational expression through documents like the Humanist Manifesto, first published in 1933 and revised several times since.

Secular humanists typically affirm human dignity, ethical living, and the pursuit of knowledge and flourishing, but insist these values can be, and should be, grounded entirely in human experience and reasoned consensus rather than in belief in God. It functions less like a single organized religion and more like a shared philosophical framework embraced by many atheists and agnostics.

Secular humanism holds that life's meaning is not handed down from above but constructed by human beings themselves, through relationships, achievement, creativity, and contribution to the wellbeing of others. In this view, purpose is something people create rather than something they discover, since there is no Creator with intentions for human life to align with.

The Bible presents meaning as discovered rather than invented, rooted in the reality that we were made on purpose, by a purposeful God: for we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them (Ephesians 2:10). Secular humanism asks us to author our own meaning from nothing; Scripture insists meaning was written into us before we ever drew breath.

Secular humanists generally affirm strong ethical commitments, honesty, compassion, justice, human rights, arguing that these values can be justified through reason, empathy, and the observable consequences of human behavior, without appeal to a divine lawgiver. Many secular humanists live admirably moral lives by ordinary standards.

Christians would agree that unbelievers can know and do genuinely good things, since God's law is written on every human heart (Romans 2:14-15). But Christians also press a harder question: without a transcendent standard, on what final authority does secular humanism ground the claim that any action is truly, objectively wrong, rather than merely unpopular or evolutionarily disadvantageous? The fool says in his heart, there is no God (Psalm 14:1) is not merely a statement about intellectual error, but about the practical instability of building lasting moral conviction on a foundation that keeps shifting with human opinion.

Secular humanism strongly affirms human dignity and worth, often quite passionately, yet many observers, including thoughtful atheist philosophers, have noted that this conviction sits awkwardly within a purely materialist worldview, where humanity is, in principle, simply one more product of impersonal, unguided natural processes.

Scripture grounds human dignity in something concrete and unshakable: God created man in his own image, in the image of God he created him; male and female he created them (Genesis 1:27). Secular humanism affirms the conclusion, that people matter immensely, while removing the very foundation, a personal Creator, that makes the conclusion coherent rather than merely asserted.

It would be unfair, and untrue, to suggest secular humanists care nothing for others; many are deeply committed to causes like scientific progress, civil liberties, education, and relief of suffering, sometimes with a consistency that puts complacent believers to shame. Their insistence on evidence, honesty, and rigorous thinking can also serve as a healthy challenge against sloppy reasoning or superstition wearing a religious label.

Christians should not treat every secular humanist commitment as an enemy to be defeated but should recognize, wherever possible, the fingerprints of common grace, God's kindness extended even to those who do not yet acknowledge him, since he makes his sun rise on the evil and on the good (Matthew 5:45).

Christians should not fear conversations with sincere secular humanists; many are thoughtful, morally serious people asking real questions about meaning, suffering, and justice, questions the gospel actually answers more fully than secular humanism can. Paul modeled this kind of engagement in Athens, reasoning directly with philosophers on their own turf (Acts 17:22-31).

The apostle told the Athenians that the God who made the world and everything in it does not live in temples made by man, nor is he served by human hands, as though he needed anything, since he himself gives to all mankind life and breath and everything (Acts 17:24-25). That is the invitation Christians can extend to secular humanist friends: not away from meaning and dignity, but toward their true source.
