This is a serious charge that deserves a serious answer. American chattel slavery used the Bible as a shield, and that shame is real. The fuller story is also real — and crucial.
The ancient context
Slavery was universal in the ancient world. Greece, Rome, the Near East, Africa, the Americas, the Pacific — there was no society without it. Estimates suggest up to a third of the Roman Empire's population were slaves. The Bible enters this slave-saturated world and begins, slowly, to dismantle it.
What the Old Testament actually does
- Outlaws kidnapping for slavery — punishable by death (Ex. 21:16; Deut. 24:7). This alone would have made the entire African slave trade illegal under biblical law.
- Mandates Sabbath rest for slaves (Ex. 20:10) — a humanitarian protection unknown in surrounding cultures.
- Requires release every seven years (Ex. 21:2; Deut. 15:12).
- Protects runaway slaves — they must not be returned (Deut. 23:15–16). The exact opposite of the U.S. Fugitive Slave Act of 1850.
- Requires generous provision when releasing slaves (Deut. 15:13–14).
- Israel's own founding story is liberation from slavery (Exodus). That memory shaped everything: "You shall remember that you were a slave in the land of Egypt" (Deut. 15:15).
In the Ancient Near Eastern context, these were radically humanitarian reforms.
What the New Testament does
- Paul to Philemon: returns the runaway slave Onesimus as "no longer a slave but more than a slave, a beloved brother" — and tells Philemon to receive Onesimus as he would receive Paul himself. This is practical abolition.
- Galatians 3:28: "There is neither Jew nor Greek, slave nor free… you are all one in Christ Jesus." The seed of human equality.
- 1 Timothy 1:10: explicitly condemns andrapodistes — slave traders, kidnappers. The translation in older Bibles ("menstealers") obscures what Paul is saying: the slave trade is a sin against the gospel.
The historical record on abolition
Abolition was overwhelmingly Christian-led:
- St. Gregory of Nyssa (4th c.) wrote the first systematic condemnation of slavery in human writing, calling slave-owning a violation of the image of God.
- St. Patrick (5th c.), himself a former slave, wrote the Letter to Coroticus excommunicating slave traders.
- The Quakers banned slaveholding among members in 1761.
- William Wilberforce (evangelical Anglican) led the British abolition movement — Slave Trade Act 1807, Slavery Abolition Act 1833.
- U.S. abolitionists: Frederick Douglass (Methodist), Harriet Beecher Stowe, Sojourner Truth, the Underground Railroad — overwhelmingly Christian-motivated.
The shame
American chattel slavery — and Christians who defended it with cherry-picked verses — is a real stain on the Church's witness. The Southern Baptist Convention was founded in 1845 explicitly to defend slaveholding; in 1995 it formally repented. That repentance is appropriate. So is repentance for the centuries when slavery persisted in Christian lands.
But the moral revulsion you feel against slavery is itself a fruit of the Christian moral imagination. It is not a default human stance — most cultures across history accepted slavery. Christianity, more than any other force, taught the world to see it as evil.
The Orthodox lens
St. Gregory of Nyssa's Homily 4 on Ecclesiastes remains one of the strongest anti-slavery statements ever written. He calls slave-owning "a sin against God himself" because it claims ownership of someone made in God's image. That voice was speaking in the 4th century.
A pastoral word
If someone tells you "the Bible supports slavery" as a one-liner, they have read half a verse without context. The deeper story — the one Tom Holland's Dominion traces at length, and he is not a believer — is that Christianity is why the modern world thinks slavery is wrong at all.
