Religious tolerance is important in maintaining social harmony in Indonesia, which is rich in diversity of faiths. This research analyses the considerations behind the prohibition of interfaith greetings and its implications for interfaith relations. The method used is qualitative research with a desktop literature review research approach, collecting data from various sources of documents and related literature. The results show that the ban issued by the Indonesian Ulema Council (MUI) is based on theological aspects and has significant social impacts. People with more inclusive views show a desire to maintain harmony despite differences of opinion regarding the ban. On the other hand, despite the influence of religious authorities, interfaith dialogue and tolerance must continue to be upheld to create balance and harmony in society. As a way forward, more intensive dialogue between religious leaders and the community is needed to find common ground to strengthen unity amid diversity.
