The Holy Piby by Robert Athlyi Rogers, first published in the 1920s, is a foundational text of Afrocentric spirituality and one of the earliest works to shape the Rastafarian movement. Written as a "Black Man's Bible," the book presents a radical theological vision that centers the divinity, dignity, and destiny of people of African descent.

Rogers crafted The Holy Piby as a sacred text of liberation-calling on Africans and the African diaspora to reclaim their spiritual and cultural identity apart from colonial and Eurocentric religious structures.
