According to Pew Research Center, nearly 75% of Black Americans identify as Christian.It’s well known that many of the first African American Christians were first exposed to Christianity in the midst of enslavement. This exposure could have been used as a tactic for control by enslavers or as a genuine attempt to lead individuals to salvation by missionaries. But, whether conversion happened out of fear or joy, the African religious practices that the enslaved people would have practiced back home, all but disappeared during American enslavement.But, when emancipation occurred in the 1860’s, the newfound freedoms of the formerly enslaved included not only an autonomy of body and identity, but an autonomy, at least in theory, of what they believed, and how they worshipped. For many, this materialized in a continued commitment to Christianity. But for many others, there was now the freedom to begin engaging with their traditional African beliefs, which often looked very different than Christianity. And even formerly enslaved Christians may have begun practicing a form of Christianity that, while still committed to the gospel, had visible distinctions and different emphases from the white men who first evangelized to them. But, while African Americans technically had the right to religious freedom, practitioners of African religion still faced persecution, especially during the era of Jim Crow, where legally free black Americans were still oppressed by their white governments for nearly a century. Even today stigma around Voodoo and similar practices has made African religion a taboo in many communities.Harvard Professor Ahmad Greene-Hayes recently wrote a book called “Underworld Work,” which explores the nuances of African American religious practice in the era between emancipation and the Civil Rights Movement. I spoke with Greene-Hayes about the complexities of Black religion during Jim Crow and the ways many Americans misunderstand African Spiritualism.
