What does the domains of theology and science of religion still have to offer to humanity at the present day threshold? Humanity seemed to have enshrined a question in its collective memory: Was religion not the reason for so many wars? Causalities of war are complex and so is religion. When both of them come together an explosive mix all too often occurrs. While analysing a conflict one needs to consider various populations involved living under conditions of war and conflict for decades or even centuries. Religious rhetoric or any type of ideology will be in customary usage for a prolonged period of time. As such religion is influencing the story society is telling itself to make sense of the world and justify what we do. However, the teachings of religions and using its language for some other end have to be clearly distinguished. Radicalization of any kind and extremist approaches are problems in and of themselves. Religion and/or other ideological agendas can serve as cover up of political and economic interests misleading with simplified conclusions. Oversimplification and an idealized approach when discussing peace and religion need to be avoided. Where is the journey as a humanity leading us? How can a theology of peace offer an inclusive, just, and transdisciplinary approach to peace-building? Grounded in a historical perspective the awareness of the presence leads to a long-term view to peace-building. The promises of religion and spiritual traditions on peace resemble their fulfilment for what it can invoke in the heart of the human being as the Parliament of World Religions declared in 1992 in Chicago. Such declarations by scholars of religion, theologians, and religious leaders express the yearning to be of service to society by following the teachings of their traditions with sincerity and a humble heart. Theology as a discipline to systemically study religious teachings by a community of scholars in a particular sociocultural context is transdisciplinary by default offering a wealth of experience. The peace-building global community has been looking to religion to prevent war and maintain peaceful relations. Organized religions can be loud and constructive moral voices in society. As such they can provide trusted leadership in war torn areas. We will look at transdisciplinary approaches to peace-building through the lenses of traditional wisdom. Religion is a vital factor for peacebuilding to be a major ally for preserving peace inside and across the nations.
