Tensions between religious communities in a nation become one of the triggers of social conflicts that result in communal conflicts based on ethnicity, religion, race, and intergroup. Communal conflict is a very crucial social issue because it can trigger a civil war that takes many victims. Communal conflict factors are generally preceded by social prejudice that makes a person or group of people deny the existence of equality and equal rights. Cases of social prejudice often arise more because of religious sentiment and sectarian politics, and or other identity politics. An understanding of religious moderation is a strong indicator for realizing social harmony in the life of pluralistic Indonesian society. Indonesia is a state of law that also embraces legal pluralism in certain legal rules. The level of understanding of religious moderation that is symmetrically related to legal pluralism becomes a problem in this paper. This research is based on quantitative research.
