How does Reformed theology compare with liberation theology with respect to the Protestant church's mission in Korea? Why has the Korean conservative church lost its social impact in its mission? Using a highly unique approach, the author examines these and other challenging questions by specifically focusing on the "Minjung," a Korean form of liberation theology. "A Comparative Study Between Minjung Theology and Reformed Theology from a Missiological Perspective" employs solid methodology and strong intelligible arguments to challenge the conservative church to regain its social significance in the face of declining popularity.
