ABSTRACT
The beauty of harmony lies in people having a feeling of security and comfort to live together in one community even though they are from different ethnic groups; different clans and they uphold different religions. Harmony is mainly created from Dalihan Na Tolu’s local ties which regulates people’s lifestyles, both in acting, behaving and in interacting with others. The research problem identifies Dalihan Na Tolu as a unifying media in order to know the roles of FKUB and the local government in preserving inter-religious harmony. Research objective is to broaden the Regional Government’s knowledge on preservation of harmony between religious communities and make it a model at the local, regional and national levels. Researchers visited respondents from various walks of life and data were gathered from in-depth observations and interviews conducted with respondents. Results indicated that each has rights and obligations both to social life, customary activities and everyday relationships.
