1. “Science Has Disproven God and the Bible.”

This objection often stems from a perceived conflict between scientific discovery and religious faith. Critics point to cosmology, evolution, and geology as evidence that the Bible’s accounts are mythological.

How to Answer: Frame the relationship between science and faith as one of different, complementary domains of inquiry. Science answers “how” questions about mechanisms and processes, while theology addresses “why” questions of purpose and meaning. Many renowned scientists, from Newton to Collins, have been devout believers. The Big Bang theory, which posits a definitive beginning to the universe, aligns with the theological concept of creation ex nihilo (out of nothing). Regarding evolution, many Christians hold to Theistic Evolution, viewing natural selection as the mechanism God employed to create life’s diversity. The key is to distinguish between operational science (testable, repeatable) and historical science (interpreting past events), recognizing that all data is interpreted through a worldview lens, whether naturalistic or theistic.

2. “Christianity is a Crutch for the Weak.”

This objection claims faith is a psychological invention for those who cannot handle life’s harsh realities, providing false comfort and avoiding personal responsibility.

How to Answer: Acknowledge that faith does provide strength and comfort, but ask if that inherently makes it false. Medicine is a “crutch” for the sick; is it therefore invalid? The deeper response is to highlight the intellectual and moral rigor of the Christian faith. Historically, it has inspired immense courage, from martyrs in Rome to dissidents under totalitarian regimes. It calls for self-sacrifice, forgiveness of enemies, and moral accountability—hardly an easy path. Furthermore, the objection itself makes a psychological claim about believers’ motives, which is an ad hominem fallacy. The truth of a belief is independent of why someone might hold it. The focus should remain on the evidence for the resurrection and the coherence of Christian theism.

3. “A Good God Would Not Allow Suffering and Evil.”

The problem of evil is the most potent intellectual objection. If God is all-powerful and all-loving, why does horrific suffering exist?

How to Answer: First, listen empathetically; this is often a heartfelt cry, not just an academic debate. Theologically, Christianity offers a multi-faceted response. It posits that God created a world with genuine free will, which necessarily includes the potential for moral evil (the actions of free agents). Natural evil (disasters, disease) is linked to the biblical concept of a creation “groaning” under the weight of humanity’s fallen state (Romans 8:22). God’s response to evil was not to eliminate it from a distance, but to enter into it through Jesus Christ, suffering on the cross to ultimately redeem and restore creation. The Christian story is uniquely one where God does not remain distant from pain but participates in it, promising final justice and healing. The existence of evil argues for an objective moral standard, which points toward a moral lawgiver.

4. “The Bible is Full of Errors and Contradictions.”

Skeptics cite alleged historical inaccuracies, scientific anachronisms, and conflicting accounts between Gospels as proof the Bible is unreliable.

How to Answer: Distinguish between apparent contradictions and actual errors. Many perceived discrepancies are differences in perspective or selective reporting, not logical contradictions. For example, different Gospel accounts of the women at the tomb can be harmonized into a coherent sequence. Encourage reading the passages in context and considering ancient literary conventions. Historically, archaeological discoveries have repeatedly confirmed details once thought to be errors (e.g., the existence of Pontius Pilate, the Pool of Bethesda). For textual transmission, the New Testament has far more and earlier manuscript evidence than any other ancient work, with 99.5% textual certainty. The “errors” objection often relies on a modernist, hyper-literal reading that the original authors did not intend. A robust doctrine of inspiration allows for human authorship styles and genres without compromising divine message.

5. “All Religions are Basically the Same.”

This pluralistic view holds that all faiths are different paths up the same mountain, teaching love and peace, with Christianity’s exclusive claims being arrogant.

How to Answer: While religions share some ethical commonalities (e.g., the Golden Rule), their core metaphysical claims are fundamentally incompatible. Christianity is unique in its central claim: God became man to die for humanity’s sins and was physically resurrected. This is irreconcilable with Buddhism’s non-theistic enlightenment, Hinduism’s cyclical karma, or Islam’s strict unitarianism. To say all religions are the same is to disrespect their distinctiveness. One can acknowledge truth and beauty in other traditions while maintaining that Jesus’s claims and resurrection, if true, have definitive implications. The question is not about arrogance but about evidence: did Jesus rise from the dead? If he did, his teachings about himself carry unique authority.

6. “Christianity is Responsible for So Much Violence and Oppression.”

Critics point to the Crusades, Inquisition, colonialism, and opposition to social progress as evidence of the faith’s harmful legacy.

How to Answer: Admit the historical failings openly. Christians, due to the doctrine of original sin, believe all people (including believers) are capable of great evil. These events were often horrific distortions of Christian teaching, using faith as a cloak for political power, greed, and prejudice. Jesus taught non-violence and love of enemy; the Crusades were a violation of that. Contrast these abuses with the positive, transformative legacy of Christianity: the founding of hospitals and universities, the abolition of slavery (led by Wilberforce, a devout Christian), the civil rights movement (led by Dr. King, a pastor), and immense charitable work worldwide. The proper standard is Jesus’s own life and teachings, not the worst actions of those who have misused his name.

7. “A Loving God Wouldn’t Send People to Hell.”

The doctrine of eternal punishment is seen as cruel and disproportionate, incompatible with a benevolent deity.

How to Answer: Reframe the discussion. Hell is not primarily a punishment for finite sins, but the eternal consequence of a person’s final, free choice to reject God and his forgiveness. C.S. Lewis famously wrote, “The doors of hell are locked on the inside.” God respects human freedom to the ultimate degree; hell is the state of existence for those who persistently choose self over God. It is the presence of justice, ensuring evil does not go unanswered. Furthermore, God’s love is demonstrated in providing a way out through Christ at great cost to himself. The emphasis should be on God’s desire that all be saved (2 Peter 3:9) and the gravity of our free will to accept or refuse that salvation.

8. “You Can’t Trust the Gospels. They Were Written Long After the Facts.”

This objection asserts the New Testament accounts are legendary developments, not reliable history.

How to Answer: Current scholarship dates the Gospels within the lifetime of eyewitnesses: Mark around AD 65-70, Matthew and Luke AD 80-85, John AD 90-95. This is exceptionally early by ancient historical standards. Paul’s letters, which affirm core gospel facts (Jesus’ death, burial, resurrection, appearances), date to the AD 50s, within 25 years of the events. The early church preserved these accounts with care, and there was insufficient time for legendary corruption of the core narrative. Furthermore, the Gospels include embarrassing details (the disciples’ failures, women as first witnesses—an unreliable source in that culture), and historically verifiable details, suggesting a commitment to factual reporting. The burden of proof is on skeptics to demonstrate how a significant resurrection belief could arise and thrive in Jerusalem just years after Jesus’ death if it were false.

9. “Morality is Relative or Evolutionary. We Don’t Need God to Be Good.”

This secular humanist view holds that morality evolved as a social construct for survival, and we can be “good without God.”

How to Answer: While we can recognize moral behavior without belief, the question is the foundation for objective moral values and duties. If morality is merely a biological or social adaptation, it is subjective and ultimately binding. Why is “survival of the species” good? On atheism, moral statements are expressions of preference or cultural conditioning, not objective truths. The widespread intuition that some acts (e.g., torturing a child for fun) are objectively wrong points toward a transcendent moral lawgiver. Christianity provides a coherent basis: humans are made in the image of a good God, imparting inherent dignity and a moral conscience. It explains why we know a moral law and why we consistently fail to live up to it.

10. “Christianity is Anti-Science and Anti-Progress.”

This objection paints faith as inherently backward, opposing scientific inquiry, critical thinking, and social advancement.

How to Answer: Historically, this is inaccurate. The scientific revolution was largely born in a Christian worldview that believed in a rational, orderly Creator whose laws could be discovered. Pioneers like Copernicus, Kepler, Galileo, Bacon, and Newton were motivated by their theistic beliefs. The university system has Christian monastic roots. On social issues, the charge often confuses theological convictions with being “anti-progress.” Christians may oppose certain cultural shifts based on biblical ethics, but they have also been at the forefront of progress in education, medicine, human rights, and charity. True faith encourages the use of reason (Isaiah 1:18) and engages critically with all domains of knowledge, seeing them as explorations of God’s creation. The conflict is not with science per se, but with philosophical naturalism that claims science is the only path to knowledge.
