Religion and dignity are a two-sided coin for followers of Indigenous Religions in Indonesia. Dignity is the relationally inherent worth in both human and non-human beings. To give and receive dignity, one ought to be religious, which is to engage in interpersonal relationships with all beings, human and non-human. This article draws on data from two decades of engagement with followers of Indigenous Religions through extensive fieldwork, activism, and community service. It explores the distinctive worldviews and practices of Indonesian Indigenous Peoples, which many have maintained in the face of external incursions by governments, corporations, and missionaries, and internal encroachments from within their communities. Their worldviews spring from interrelational cosmology, which posits that relational dignity is a religious norm. This cosmology is institutionalized with adat (customary) systems that enact and reproduce relational dignity. The article concludes with a call to better understand and recognize Indigenous Religions by expanding the definition of religion to include the notion of relational dignity when considering how scholars and policymakers conceptualize and implement policies on freedom of religion or belief.
