The article begins by explaining that International Relations has traditionally been shaped by a state-centered view of global politics. In this view, sovereign states are treated as the main actors, while religion and non-state institutions are often placed at the margins. This assumption is linked to the Westphalian legacy and secularization theories that expected religion to withdraw from public and political life.
The article argues that this older view is no longer adequate because religion has re-emerged in global affairs through social movements, humanitarian work, political activism, and transnational advocacy. Religious-Based Organizations, or RBOs, are especially important in this transformation because they combine moral claims, organizational capacity, and community trust. Their growing visibility challenges the idea that international politics can be understood only through formal diplomacy and state behavior.
Southeast Asia is presented as a particularly important region for examining RBOs because religion remains deeply embedded in social life, public discourse, and political mobilization. The article positions RBOs not as peripheral actors, but as participants in the evolving structure of regional peacebuilding and governance. Their work is especially relevant in societies marked by religious diversity, uneven state capacity, communal tension, and humanitarian need.
The central problem identified in the introduction is the mismatch between the practical importance of RBOs and the limited conceptual attention given to them in mainstream International Relations. In many Southeast Asian contexts, state institutions struggle to build trust and legitimacy, especially in conflict-affected or socially fragmented communities. RBOs often enter this gap by mediating disputes, delivering aid, and sustaining community relationships that formal institutions cannot easily reproduce.
The article reviews existing scholarship showing that religion has not disappeared from international politics and that non-state actors increasingly shape regional and global outcomes. Faith-based actors have been recognized for their contributions to humanitarian intervention, development, norm diffusion, and peace advocacy. Southeast Asia’s religious diversity, including Muslim, Buddhist, Christian, and indigenous traditions, provides a rich setting for understanding how religion remains connected to social cohesion, political mobilization, and conflict.
However, the article identifies a research gap in how RBOs are conceptualized within International Relations. Existing studies often acknowledge their practical role but do not fully explain how their religious identity, moral authority, and transnational networks interact with formal governance structures such as ASEAN. RBOs are often visible in case studies but remain underdeveloped in broader theories of regional governance and political agency.
The theoretical framework is built through Constructivism, Liberalism, and the concept of sacred capital. Constructivism helps explain how identity, norms, and moral authority shape public legitimacy and collective behavior. Liberalism allows attention to transnational actors, interdependence, and multi-level governance beyond the state. Sacred capital explains how RBOs gain authority through historical depth, spiritual reputation, educational networks, and recognized moral leadership.
The article is guided by questions about how RBOs should be understood as non-state actors in Southeast Asian regional politics, what distinctive features allow them to influence peacebuilding and governance, and how they engage with formal structures such as ASEAN. It also asks what institutional, political, and internal barriers limit their effectiveness. The urgency of these questions comes from Southeast Asia’s need for peacebuilding mechanisms that are socially legitimate, locally rooted, and regionally connected.
