This thesis examines the Kachin traditional religion in Myanmar in light of the growing theological interest of the Catholic Church in the study of traditional religions. It approaches the Kachin traditional religion through the lens of Christian pneumatology, focusing on the nature of the Supreme Being (Karai Kasang) and spirits (nats). This paper then examines the experiences and understanding of the adherents of the Kachin tradition and the Kachin Christians, personal interviews of whom were conducted to supplement the written resources. It shows that many beliefs of the Kachin traditional religion appear to be compatible and resonate with that of Christians’, yet the unique way of understanding and living with the spirits challenges the Christian pneumatology. To be able to better understand the Kachin traditional religion, one needs to put on the cultural lens of the Kachin. This thesis shows that there is need for Christians to acknowledge the noble, beautiful, and sacred spiritual traditions of the Kachin such as an acute sense of sacredness and divine presence, Supreme Being as sustainer and life-giving Spirit, spirits as mediators and protectors, and a profound notion of offering as a solemn means of communication. The constructive relationship between Christianity and Kachin traditional religion can help facilitate ongoing inculturation of the liturgy in the Kachin Churches.
