The use of Scripture in advocating the practices of chattel slavery, or legitimizing the abolitionist cause, has been widely discussed in American history, with scholars like Forrest G. Wood, Stephen R. Haynes, and Mark A. Noll arguing that the Bible shaped views on slavery in America. However, studies like these have not sufficiently covered the writings of many prominent abolitionists, particularly Angelina Grimké, a former slaveholder from the South. My paper addresses Grimké's use of Scripture in her major abolitionist writings: "Slavery and the Boston Riot" (1835), "Appeal to the Christian Women of the South" (1836), "An Appeal to the Women of the Nominally Free States" (1837), and "Letters to Catherine E. Beecher" (1838). In my project, I examine Grimké's persuasive techniques, detailing how she used Scripture to persuade women to join the abolitionist cause, which presents a new facet of the history of the Bible in America. I contend that Grimké used Scripture to make a human rights abolitionist argument, to inspire women to stand up against slavery, and to give herself authority as a prophetic voice to the United States. My project, by closely examining Grimké's use of Scripture, brings a key witness to a rarely acknowledged, but prominent, means of abolitionist persuasion.
