Moral Progress Happens Against Scripture, Not Because of It

A common claim from religious apologists is that morality comes from scripture and that without it humans would have no foundation for ethical behavior. The actual historical record tells a different story. On nearly every major moral question of the last two centuries, humanity has made progress despite the holy books, not because of them. The moral arc has bent away from scripture, not toward it — and the institutions that resisted the bend the longest were almost always the religious ones.

Slavery

The Bible does not condemn slavery. It regulates it. Leviticus 25:44-46 explicitly authorizes the buying of slaves from neighboring nations and passing them as property to one's children. The New Testament instructs slaves to obey their masters (Ephesians 6:5, Colossians 3:22, 1 Peter 2:18). Paul sends a runaway slave back to his owner (Philemon).

When abolitionists fought to end slavery in the 19th century, the pro-slavery side had scripture on its side. Southern preachers preached pro-slavery sermons from biblical texts. The Southern Baptist Convention was founded in 1845 specifically to defend the right of Christians to own slaves. The abolitionists won not because they read scripture more carefully but because they appealed to a moral standard outside scripture — the dignity and equality of all human beings, a principle scripture does not clearly endorse and frequently contradicts.

Women's Rights

Scripture is, by modern standards, deeply misogynistic. Women are property in the Tenth Commandment, listed alongside livestock. They are forbidden to teach men (1 Timothy 2:12), commanded to be silent in churches (1 Corinthians 14:34), and held responsible for the fall of humanity (1 Timothy 2:14). The Quran permits men to beat disobedient wives (4:34) and gives women half the inheritance share of men. The Old Testament includes laws by which a rapist could marry his victim (Deuteronomy 22:28-29).

The movement for women's suffrage, equal pay, reproductive rights, and the right to leave abusive marriages was opposed, at every step, by religious authorities citing scripture. The progress was made over the objection of clergy, not at their direction. When the religious eventually caught up, they did so by reinterpreting passages — selectively ignoring the inconvenient ones — under pressure from secular moral progress.

LGBT Rights

Leviticus 20:13 prescribes the death penalty for male homosexuality. Romans 1 condemns same-sex relations. The Quran tells the story of Lot as a condemnation of homosexuality. For most of history, religious authority was used to criminalize, persecute, and execute gay people.

The recognition of LGBT humanity over the last fifty years was driven by secular human rights principles, gay rights activists, and changing cultural attitudes — over fierce religious opposition. The churches that have softened on the question have done so reluctantly, decades after secular society moved, and many still have not. Once again, scripture had to be reinterpreted, downplayed, or ignored to allow moral progress to occur.

The Pattern

The pattern is consistent across issue after issue:

1. Scripture endorses or permits the practice.
2. Religious authorities use scripture to defend the practice for centuries.
3. Secular reformers, often at great personal cost, push for change on grounds of human dignity, equality, or reason.
4. Eventually, a tipping point is reached and the moral consensus shifts.
5. Religious institutions reinterpret scripture to claim they were on the right side all along.

Step 5 is the move you should pay attention to. It demonstrates that scripture is not the source of the moral judgment — it is retrofitted to whatever moral judgment the surrounding culture has reached. The believer's actual moral compass is calibrated by the broader society, and scripture is consulted only afterward, with cherry-picked passages used to baptize the conclusion.

"But Religion Inspired Some Reformers!"

True. Some abolitionists were Quakers. Martin Luther King Jr. was a Christian minister. Religious motivation did push some individuals toward moral progress.

But this does not vindicate scripture. It vindicates the human capacity to find moral inspiration anywhere, including in religious traditions interpreted creatively against their plain meaning. King's appeal was not "the Bible says slavery and segregation are wrong" — it was an appeal to universal human dignity, dressed in biblical rhetoric for an audience that responded to it. The same principle is available to anyone, religious or not.

And for every King, there were a dozen religious authorities on the other side of the issue, also citing scripture. If religion is responsible for the reformer, it is equally responsible for the segregationist. The variable is not the religion; it is the human being using it.

The Implications

If morality came from God via scripture, then scripture should be ahead of human moral intuition, not behind it. A 3,000-year-old book authored by a perfectly good being should contain timeless wisdom that puts modern ethicists to shame. Instead, it contains the moral assumptions of bronze-age and iron-age societies — assumptions we have, slowly and painfully, learned to outgrow.

The honest reading of moral history is that humans figure out morality by reasoning, experience, and gradual expansion of the moral circle, with scripture serving as a lagging indicator at best and a brake on progress at worst. This is exactly the pattern we would expect if morality is a human achievement, not a divine gift.

Conclusion

Moral progress over the last two centuries has been a story of humanity outgrowing its scriptures. Slavery, women's subordination, the criminalization of homosexuality — every one of these wrongs was endorsed or permitted by holy books and defended by religious authorities. Every one of them was overturned by people appealing to standards outside scripture. The claim that morality comes from religion is not just historically backward; it inverts the actual relationship. Religion has needed morality to drag it forward, not the other way around.
