The idea of religious revival among slaves was a common practice.  Sometimes, they united under a specific church.  Other times, as in Toni Morrison's Beloved, slaves gathered under the guise of their own breed of religion.  Baby Suggs, the grandmother of Sethe in Morrison's novel led such a group of slaves.

"Uncalled, unrobed, unanointed, she let her great heart beat in their presence.  When warm weather came, Baby Suggs, holy, followed by every black man, woman and child who could make it through, took her great heart to the Clearing...She did not tell them to clean up their lives or to go and sin no more.  She did not tell them they were the blessed of the earth, its inheriting meek or its glorybound pure." (Morrison, 87-88)
