American Christians did not merely stand on opposite sides of slavery. They often argued from the same Bible, appealed to the same God, and accused one another of betraying Christianity. That history resists two simple stories: that Christianity straightforwardly created abolition, or that religion served only to protect slavery.
The more difficult record shows scripture functioning as a contested authority. Proslavery ministers found direct permissions and regulations. Antislavery Christians emphasized creation, neighbor-love, deliverance, human equality, and the moral direction of the gospel. Enslaved Christians also interpreted the faith from inside a system that used Christian language to control them.
The proslavery case was not a vague appeal to tradition
Thornton Stringfellow, a Virginia Baptist minister, stated the biblical defense with unusual clarity. In his 1841 essay, later republished in 1850, he defined the disputed institution as holding another person without consent as transferable property, including that person’s descendants. He was not defending temporary employment and calling it slavery. He meant hereditary human ownership.
Stringfellow’s own argument preserved by the Library of Congress proceeded in stages. The patriarchs owned servants. Mosaic law allowed Israelites to acquire bondmen and bondmaids from surrounding nations in Leviticus 25:44-46. The New Testament told servants to obey masters in Ephesians 6:5 and 1 Timothy 6:1-2. Paul returned Onesimus to Philemon without commanding the abolition of slavery. Jesus never issued an explicit prohibition.
The argument gained force from a common Protestant rule: if scripture permits something and never revokes that permission, Christians cannot declare it inherently sinful. Stringfellow therefore treated abolitionists as placing modern moral opinion above the Bible. He also used Genesis 9:25-27, where Noah curses Canaan, to place enslavement inside a providential story about peoples and descendants.
That last move involved assumptions not found in the passage. Genesis curses Canaan, not Ham, and says nothing about skin color or African ancestry. Yet the interpretation became useful because it attached a racial system to sacred history. By the 1850s, according to Paul Gutacker’s study of antebellum Christian memory, many religious defenses of Southern slavery also assumed innate racial difference and described slavery as a paternalistic benefit that brought Christianity and civilization to Africans.
The biblical problem cannot be solved by changing one word
Modern defenses sometimes answer that biblical servants were merely employees or debtors. That is too broad. Biblical slavery included several arrangements, and they were not identical to nineteenth-century American racial chattel slavery. Even so, Leviticus 25 distinguishes Israelite debt service from foreigners who could be acquired as property and inherited. Roman slavery in the New Testament was also coercive ownership, not a voluntary employment contract.
Historical difference matters, but it does not erase ownership. Proslavery writers understood this. Stringfellow cited the differences between hired servants and bondservants precisely because he wanted to show that the Bible permitted involuntary, hereditary slavery. A responsible reading should neither pretend the ancient systems were identical to American slavery nor soften every biblical slave into a modern wage worker.
The New Testament does place obligations on masters and describes enslaved and free believers as one body in Christ. Galatians 3:28 says that in Christ there is neither bond nor free. Philemon asks that Onesimus be received as a beloved brother. Those texts could destabilize slavery’s moral logic. They do not directly command Christian slaveholders to emancipate the people they owned. That silence gave the proslavery case its strongest textual advantage.
Antislavery Christians changed the frame
Christian abolitionists rarely depended on a single prohibition. They argued from a wider account of the Bible. Human beings bear God’s image in Genesis 1:27. The Exodus depicts God hearing the cries of an enslaved people. Jesus commands love of neighbor and treatment of others as one would wish to be treated in Matthew 7:12 and 22:39. First Timothy 1:10 condemns “menstealers” in the KJV. These themes made treating a person as saleable property incompatible with Christian duty.
Angelina Grimké’s 1836 Appeal to the Christian Women of the South answered the claim that the Bible sanctioned American slavery. She argued that the dominion granted in Genesis extended over animals, not fellow human beings. She joined biblical equality to the Declaration of Independence and insisted that inheriting an enslaved person did not make the relationship morally legitimate.
Grimké also made interpretation practical. Christian women should read, pray, speak, teach enslaved people, petition legislatures, and free those they held even when state law imposed a penalty. She cited the Hebrew midwives, Daniel, and the apostles as examples of obeying God when law commanded wrongdoing. Her case used scripture as a warrant for moral resistance, not merely private disapproval.
Frederick Douglass made the conflict sharper because he wrote from experience under Christian enslavers. In the appendix to his 1845 Narrative, he distinguished the Christianity of Christ from the “slaveholding religion of this land.” The point was not that faith had been absent from slavery. Churches, ministers, revivals, missionary giving, and biblical instruction could coexist with whippings, stolen labor, and the sale of families. Religion sometimes intensified the hypocrisy by giving ownership a sacred defense.
Christians also argued about how scripture should work
The dispute was not only over which verses to quote. It concerned whether Christian ethics could condemn an institution that scripture regulated but did not explicitly abolish. Proslavery interpreters emphasized direct commands, permissions, and apostolic practice. Antislavery interpreters often appealed to principles they believed scripture set in motion: equality before God, love, liberation, and the gradual moral effect of the gospel.
Gutacker’s research complicates the idea that each side relied on the Bible alone. Defenders of slavery cited church fathers and centuries of Christian slaveholding to show that the institution had long coexisted with orthodoxy. Black and white antislavery writers also used church history, arguing that Christian teaching had weakened slavery and that emancipation completed that moral movement. Scripture was read through memories of the church, inherited social arrangements, political loyalties, and assumptions about race.
This helps explain why sincere professions of biblical authority did not produce agreement. A reader’s method already determined which evidence carried the most weight. Is an explicit permission decisive? Can a broad moral principle overturn an accepted practice? Does silence mean approval, temporary accommodation, or incomplete reform? The text did not answer those questions without interpreters making judgments about history and morality.
The argument broke churches before it broke the nation
Slavery fractured national Protestant institutions. The United Methodist Church’s historical account notes that early American Methodism formally prohibited participation in slavery, then relaxed or failed to enforce the rule where slavery was legal. In 1844, conflict over slaveholding bishop James O. Andrew helped divide Methodists into northern and southern churches.
Baptists separated the following year amid disputes over slavery and church cooperation. Presbyterian divisions were more complicated, mixing disputes over revivalism, authority, and slavery, but they also hardened along sectional lines. Gutacker notes that the major Protestant schisms pushed both sides to recruit the Christian past as evidence that their own communion represented faithful tradition.
Geography and material interest mattered. Biblical interpretation did not float above plantation wealth, racial hierarchy, fear of social upheaval, or the experiences of enslaved people. Christians often found readings that protected the world around them. Others, especially Black Christians and abolitionists who listened to testimony from slavery, found that the same inherited framework had become morally intolerable.
What later repentance acknowledges
Denominations have since revised their public memory. In 1995 the Southern Baptist Convention adopted an official resolution on racial reconciliation acknowledging that many Southern Baptist forebears defended slave ownership, supported or accepted American slavery, and later resisted civil-rights efforts. The resolution repudiated slavery and racism and asked forgiveness.
That confession matters because it refuses the claim that only a few outsiders misused an otherwise unambiguous faith. The defense of slavery was preached by ministers, organized through churches, and argued from scripture. Christian abolition was also real. Believers organized, petitioned, wrote, preached, escaped, resisted, and sometimes accepted punishment because they understood emancipation as obedience to God.
The history leaves no simple verdict
It is inaccurate to say that Christianity alone ended American slavery. Political conflict, resistance by enslaved people, abolitionist organizing, war, and federal power were indispensable. It is equally inaccurate to treat Christian abolition as a disguise for secular morality. Many abolitionists reasoned in explicitly theological terms and believed scripture obligated them to act.
The harder conclusion concerns authority. A revered text can constrain interpretation, but it does not interpret itself. Christians deciding what the Bible meant about slavery brought moral intuitions, social interests, historical assumptions, and the testimony they were willing to hear. The proslavery side could point to permissions and regulations. The antislavery side could point to human dignity and the direction of the gospel. Their disagreement shows why citing scripture is not the end of a moral argument. It is often the point where the most consequential interpretive choices begin.
