The purpose of this paper is to examine some religious reformers and mission ideas. There are some negative aspects on the mission ideas of Religious reformers until now. Except theologians of Roman Catholic Church, Gustav Warneck, who is the father of modern missiology, also evaluated that there were not any mission ideas and mission activities to religious reformers, for Luther did not recognize mission duty, compared with those Roman Catholic which made inroad and was active abroad more than before.However, the study that there was mission to religious reformers was presented by western and Korean scholars. Despite of this positive study, the center of criticism is that if they have mission ideas and theology, how their ideas and theology are systematic and have persuasive power. Therefore, the evaluation to them may be more negative judging from the circumstances resulted in the geographical expansion of gospel and numerical increase of believers because the mission of christianity after 19th century which was called as ‘The Great Century,’ produced a large number of missionaries abroad.Through the examination of results and a limit about the study on the mission ideas of religious reformers until now, this paper, on the other, presented the mission as ‘a witness.’ Jesus Christ gave Great Commission to his disciples, and all of them carried out their duties as the witness of gospel through religious martyrdom. The Latin ‘martyrium’ of ‘martyrdom’ came from the Hellas ‘μαρτυριον.’ The ‘μαρτυριον’ means originally the word ‘witness’ and ‘evidence.’ The etymology of the word ‘witness’ and ‘evidence’ is the same.The martyrdom is the ultimate evidence of gospel. Martyrs strongly impressed to christian community as the witnesses of gospel in their lives, and took the role of enthusiastic missionaries leading the others to faith. Consequently, this paper analyzed their practice more than their theory on the mission of religious reformers, that is, their lives as a martyr for the truth, Jesus Christ. This is because the martyrdom for gospel is the most obvious witness and mission of gospel at once.
