During a Christian revival movement on Ahamb Island in Vanuatu in 2014, gender- and age-based hierarchies were inverted as women and children were given divine authority and men were positioned as threats to sociopolitical renewal. In analysing these events, the article develops Kapferer’s insights on the inherent openness and unpredictability of ritual dynamics. However, this article argues that such openness and unpredictability can also be tied to external factors including participants’ multiple and sometimes incompatible values and interests. Attempts to resolve ambiguities in ritual may eventually feed back into ritual ideology and practice in ways that make participants’ experiences disturbing and problematic rather than orderly and supportive.
