During the period of Apartheid as an infamous historical fact in South Africa, Belhar Confession was emerged in a small town of Belhar located in the suburb of Cape Town. Belhar Confession is similar to Kairos Document (1985) in that both of them are aimed to against Apartheid and its overarching effects. Korean church and society might get some insights from Belhar Confession in order to heal their division and conflict. Thus, an introduction and an evaluation of this confession, which pursues unity, reconciliation, and God’s justice in opposition to any kind of racism, are implemented. The purpose of this article is to analyze and evaluate the Belhar Confession, which has not yet been evaluated from the perspective of the New Testament in terms of New Testament theology. For this aim, the following 4 steps of studies are taken: (1) The history of Belhar Confession and the discourse analysis on it, (2) the theology of Belhar Confession, (3) an evaluation of unity, reconciliation, and justice as three cores of Belhar Confession in the light of the New Testament, and (4) application of Belhar Confession into the Korean context. In addition, general studies are attempting to converge and expand the horizons between disciplines by mobilizing multidimensional methodologies or through consilience. This study intends to leave a meaningful model and precedent that promotes interdisciplinary research between New Testament theology and systematic theology of confession of faith.
