This article examines two different missionary areas where the Society of Jesus was sent to evangelise the native population: the Andean territories previously under Inca domination and the remote Mariana Islands in the Pacific Rim. The gathering of “other barbarians” living outside “civilised” societies was a tool of early modern colonisers within Europe and beyond. The English did so in sixteenth-century Ireland and the Spanish began reducing the so-called American Indians to new settlements in New Spain and Peru. In this paper, I want to compare the methods used to concentrate the natives of the Viceroyalty of Peru, where the Jesuits actively collaborated, with the borderland mission of the Marianas, where the Jesuits worked as parishioners of a much less sophisticated people: the CHamoru.1 As I will demonstrate, this policy of gathering souls was not an isolated one, but part and parcel of a universalistic principle of spreading God's word that was irremediably embedded in colonial structures of coercion and political control in the Americas and Asia-Pacific.
