Instituted in 1540, the Society of Jesus had the mission to expand the Christian faith around the world, in a context where Protestant ideas were spreading in Europe. When they landed in the Iberian colonies, the Jesuits soon stood out for their pastoral action and educational system, which had the native population as their starting point, besides the textual production, such as letters, manuscripts, books, etc. The three manuscripts used in this research were species of "manuals" that brought recommendations to hermanos administrators and lords of engenho for the conduction of haciendas and engenhos and the relationship with slave labor. The fact that colonial society revolved around land and slaves, and the need to generate revenue for the maintenance of missionary actions, which made the Society of Jesus also became the owner of land and African labor, caused the Jesuits to reflect on the administration of rural properties and the treatment received by slaves.
