Abstract

This article examined the recent emergence of the national and international issue of religious polarisation and identity, which affects some groups’ populism and fanaticism. Regarding social phenomena, religion and identity are intertwined like the two sides of a coin. This discourse has an impact how to interpret diversity on religious issues that are caused by political influences. Given the polarisation of identity politics and religion, the national and state campaign slogan ‘unity in diversity’ is merely wishful thinking. The polarisation of identity and religion is heavily implicated in the Indonesia–Philippines border case; consequently, in some instances, the ‘seeds’ of these cases are discovered, eventually resulting in group fanaticism. This article employed the historical way of writing while also taking a social science angle that interacts with the research being done. For some communities, religion and identity may take on symbolic meaning, affecting how well they adapt and are accepted. However, the qualities of a community group or region are also shaped by historical events. According to the study’s findings, religion and ethnic identity have played important roles in long-standing historical processes and impacted them. This study is anticipated to ‘suppress’ the problem of political division involving religion and identity because the identification of ‘border’ communities depends not only on entity and identity issues but also on the community’s culture.Contribution: The contribution in this study is that it has an impact on religious issues and cultural identity relations perspectives.
