Early mission history to Latin America has been seldom studied by Korean mission scholars. Western scholars’ investigations on early violent contacts between Europe and New World have been focused on either ‘sorrymode’ (for Iberian scholars) or ‘wearesomebody mode’ (for Hispanic scholars). In the paper, the author argues a story of Christian mission, rather sad and dramatic: the life of native Peruvian Jesuit, Blas Valera. He was born mestizo between conquistatores father and mother from Inca royal family. His profound knowledge about Inca native culture and acute sensitivity of native languages made this Jesuit priest excellent missionary translator and later, missionary to native people himself. However, his theological openness to local culture and audacious identification between Inca’s supreme being and the Christian God caused a lot of troubles and controversies. During the Third Lima Council, the clash between Jose de Acosta, a Jesuit Provincial and adamant advocate of eradicating native component of the Christian faith, and the flexible Blas Valera was not avoidable. Jose de Acosta and the European Jesuit community in Peru charged Valera with sexual abuse and put him into jail. Later, it is said that Valera was sent to Spain, by the repeated request of Jose de Acosta, and was kill by English pirate in 1597. However, new discoveries of Valera’s writing possibly reveals that he was not killed in Spain; rather, he returned to Peru and wrote an important treatise, called Nueva coronica y buen gobierno, under the authorship of Guaman Poma. The author of this paper supports the authenticity of Vakera’s newlydiscovered documents and new theory, due to the same missionary points of Valera and Poma.
