This paper explores Ham's role as a maverick thinker, a pacifist and an innovator of religious pluralism in twentieth century Korea. Ham saw an individual's spiritual quest and the struggle for social justice as interrelated. As an idealist, Ham viewed human beings basically as moral beings, and perceived the Supreme Being or God not only as a transcendental being, but also as an imminent being both in the sense of existing everywhere and also in the sense of existing as `inner (...) voice'. On this basis, my paper examines Ham as an intermediary between East Asia and the West and between `losers' and `winners' in history, and assesses how he was shaped by, and responded to, the challenges of his time. Firstly, I will look at Ham's search for Korea's national identity under Japaneseimperialism and his determination to write an account of Korean history from the standpoint of the oppressed, in order to inspire his downhearted countrymen. I will also examine how, using his own Biblical interpretation of Korean history, Ham provided a mission and vision not only for oppressed Koreans under Japanese colonialism, but also for 'losers' and ordinary people everywhere. In the second section, I will further explore Ham's sense of pacifism by examining how Ham's ideas were open-ended not only towards the Asian classical philosophies of Taoism, Confucianism, Buddhism and Hinduism, but also towards traditional Christianity, the non-church movement, Quakerism, Western sciences and rationalism. I will also consider why he had to respond as an individual to the challenges both of society and of the historical era. In the third section, I will concentrate on how Ham's Christo-centric views had fundamentally altered to a more universal perspective and also how he asserted the necessity for the restoration of Christianity from the ceremonial and `weird' to the ethical and socially just. Lastly, I will look at Ham's definition of Jesus and why he used the new terminology the 'Ssial' instead of the archaic expressions 'people' or 'national.' By doing so, I will examine how Ham achieved what is one of the most difficult things in this world, to be a genuinely conscientious leader despite corrupt surroundings. (shrink)
