This study examines the Holy Aruosa Cathedral in Benin City, Nigeria, as a unique example of religious syncretism that blends traditional Edo spirituality with Christian elements introduced in the 16th century. Often misunderstood or reduced to stereotypes, the cathedral represents cultural resilience and spiritual innovation, providing insight into the adaptive nature of the Edo people. Using a qualitative case study approach, data was collected through oral interviews with clergy, congregants, and community leaders, as well as participant observation of worship service and archival materials. By analysing oral histories and the Book of Saint Aruosa, the paper explores the origins, structure, and enduring role of the cathedral in preserving cultural identity, fostering community, and challenging conventional narratives of |syncretism. The findings underscore the importance of local perspectives in understanding how faith and culture intertwine, demonstrating how the cathedral continues to embody the dynamic integration of Nigerian heritage with external religious influences.
