The Holy Piby is an early 20th century prophetic vision and theological treatise intended to unite Diasporic Blacks in a holy union of prosperity and hope. Written by Robert Athlyi Rogers in 1924 The Holy Piby is the first of three foundational religious texts adopted by the Rastafarian faithful. This edition by scholar and theologian W. Gabriel Selassie I, is the first and only comprehensive book that provides a full analysis of the mission and sermon of Robert Athlyi Rogers and his Afro-Athlican Constructive Gaathly.
