This paper examines Belhar's confession of faith, which declared resistance to Apartheid that was notorious for its distorted social policies in South Africa in the 20th century. Referring to the critical perspective of the past in which the Christian church played a decisive role in the beginning and end of its policy, the text observes its characteristics and responses in three aspects. First, it is looking at the distorted theological interpretation and criticism of its history of influence that promoted and justified racial injustice in the society. This policy, which pursued explicit social oppression and division, is regarded as a product of the church that inherited modern culture in the 19th century. The fact that Christian pastors' roles were crucial in the proposal and implementation of this policy shows that the church can derive wrong decisions when accepting distorted spiritual culture without filtration. Second, the fact that the church played a decisive role in overcoming this policy and its history of influence also shows that the theology of the church can establish itself as a hope of overcoming and correcting racial injustice in the society. In particular, the text shows that theological direction that emphasizes the role of the church and the Trinity, including the Barmen Theological Declaration, plays a major role. Third, the text concludes by examining the objectives contained in Belhar's confession of faith, which aims for unity in diversity amid the challenges of the 21st century. Belhar's Confession, which emphasizes tolerance for others and the way to live with strangers, also raises questions for Korean society, which is entering the path of multiculturalism and diversification. It is asking what the role of the church is for true social integration.
