Answer: Southern slaveholders often used biblical passages to justify slavery. Those who defended slavery rose to the challenge set forth by the Abolitionists. The defenders of slavery included economics, history, religion, legality, social good, and even humanitarianism, to further their arguments.
Explanation: Defenders of slavery argued that the sudden end to the slave economy would have had a profound and killing economic impact in the South where reliance on slave labor was the foundation of their economy. The cotton economy would collapse. The tobacco crop would dry in the fields. Rice would cease being profitable.
Defenders of slavery argued that if all the slaves were freed, there would be widespread unemployment and chaos. This would lead to uprisings, bloodshed, and anarchy. They pointed to the mob's "rule of terror" during the French Revolution and argued for the continuation of the status quo, which was providing for affluence and stability for the slaveholding class and for all free people who enjoyed the bounty of the slave society.
The Negro's Place in Nature
Some slaveholders believed that African Americans were biologically inferior to their masters. During the 1800s, this arguement was taken quite seriously, even in scientific circles.
Defenders of slavery argued that slavery had existed throughout history and was the natural state of mankind. The Greeks had slaves, the Romans had slaves, and the English had slavery until very recently.
Defenders of slavery noted that in the Bible, Abraham had slaves. They point to the Ten Commandments, noting that "Thou shalt not covet thy neighbor's house, ... nor his manservant, nor his maidservant." In the New Testament, Paul returned a runaway slave, Philemon, to his master, and, although slavery was widespread throughout the Roman world, Jesus never spoke out against it.
