This thesis consists of two parts. The first part begins by examining foundational perspectives using the theological method of the Methodist Quadrilateral: Scripture, Tradition, Reason, and Experience. It explores the biblical foundations of peace, the historical and theological engagement of Methodists with peace, reasoning how peace studies as an interdisciplinary tool for developing a theology of peace, and examins the lived experiences of Malaysian Chinese, illustrating how these experiences inform theological reflection to develop a theology of peace. These perspectives then inform a systematic approach to developing the theology of peace, structured around four key theological themes. First, God the Creator establishes the ontological of peace through creation, human dignity, and the image of God. Second, Jesus the Redeemer reveals how peacebuilding in the Malaysian context is shaped through embodying reconciliation, nonviolence, and redemptive suffering from a Malaysian Chinese perspective. Third, Spirit the Advocate sustains peacebuilding by empowering Malaysian Chinese Methodists in multiethnic, multireligious, and multicultural contexts. Fourth, an eschatological peace envisions the ultimate fulfilment of peace in Christian eschatology, shaping contemporary peacebuilding efforts. The thesis highlights the implications for an interdisciplinary study of peace theology. It focuses on the role of Malaysian Chinese Methodist peacemakers in navigating conflicts and building peace in a multiethnic, multireligious, and multicultural society. Eventually, it provides critical and holistic responses for understanding and addressing war, violence, conflict, and peace issues. Ultimately, this interdisciplinary examination of peace theology, developed as a Malaysian Chinese Methodist Peace Theology, makes a meaningful contribution to contemporary discussions in peace theology, public theology, Asian theology, Christian social ethics, and Global Methodism.
