In our unprecedented situation of globalized crisis of war, violence, poverty and environmental destruction, the importance of diakonia as the love of the others and the service for the others has recently been reignited in Christian practices. Diakonia as humble service or table service which has traditionally been misinterpreted can be connected to an honourable and high-level authorization for mission for the others. My suggestion is that diakonia as an honorable act is linked with prophetic- apostolic service for “the rule of shalom”. Peace-making is the core-matrix of the gospel and the very nature of diaconia. Christian identity in early church was differentiated from two approaches: Jewish approach to reach to the Sacred by the way of religious rituals and Pax Romana as the peace by the power of violence, war and control. Jesus and his followers embodied the vision of God’s dominance- free order into their lives and their world as a new reality, rather than just idea. As we know well in gospel, Jesus and Paul introduced this new reality to the conflict world: the engaging power of equality, partnership, inclusiveness, active nonviolent struggle and reconciliation. Gandhi re-inspired modern Christian peace movement with some insights and social skills, and let modern Christian discipleship be connected with social sciences such as conflict transformation, nonviolent direct action, restorative justice/practice or peace-building. In our violent world, the challenge towards the churches’ mission is to give ministry of peace and reconciliation to the suffering others. The primary tasks for this practice of peace witness in the world require the capacity-building for peace activism and the establishment of system for peace training. With the accomplishment for these tasks, we can bring God’s sovereignty into arenas of conflict, violence and dominant system. This will be how we as Christians may glorify God in our mundane work.
