The purpose of this essay is to explore the relationship between Christian religion and colonialism, as well as missionary influences on Indigenous peoples. The article is divided into three parts. The first part discusses the harm and destruction that Christian religions may cause to the Indigenous peoples in the missionary process from postcolonial perspectives. The second part explores the possible emancipation drawing from Indigenous Peoples' worldviews and knowledge; including the non-anthropocentric worldview, the notion that all creations are related, and the conviction that human beings belong to the Land. The third part captures "reciprocity," "balance," and "interrelatedness" in the tradition of Taiwan's Indigenous Peoples' ideology as ideological resources for decolonization. The conclusion of this paper points out that although Indigenous peoples suffered great harm in the Christian missionary process, it is still possible to build emancipatory Christian theologies from Indigenous knowledge and cultural traditions.
