This collection contains materials gathered and produced in the course of the Goffs' work, particularly in the areas of religious liberty and religious implications of social development in Latin America. The papers provide first-hand perspective on major shifts taking place in Protestant missions in the later 20th century, including the nationalization of Latin American churches and the rise of liberation theology. The collection is strong in documenting the Goffs' early career in Colombia (1947-1969), the pivotal period of their research assignment in Cuernavaca, Mexico (1969-1973), their work in Nicaragua (1981-1986) and their retirement activities (1986-2000). Material from their years in Peru (1973-1981) is scarce. James and Margaret Goff were fraternal workers (missionaries) serving under the United Presbyterian Church in the USA (PCUSA after 1983), in Latin America (Colombia, Mexico, Peru, Nicaragua) from 1947 to 1986. They served as interpreters of Latin American liberation theology to a Protestant Anglophone audience, translating and distributing important religious documents to church leaders in North America.
