This paper examines the particular shape taken by a modern instance of ‘Third World’ feminism. In Papua New Guinea, an emerging nexus between grassroots female activism and Christian churches is helping to liberate and empower some female citizens in a state which in practice has neglected women’s interests and gender relations despite early national rhetoric about the importance of women to nation-building. Tracing the origins of modern women’s fellowship groups to the early work of female missionaries with indigenous women, the paper considers the increasing politicization of women’s organizations during the last two decades as they expand their ‘traditional’ preoccupation with spiritual, domestic, and welfare matters to embrace wider social, political, and human rights issues. In the course of surveying church women’s groupings in Papua New Guinea, the paper looks specifically at the National Council of Women, women’s groups in East New Britain Province, the United Church Women’s Fellowship, and women’s involvements in the developing ecumenical movement. The paper concludes by contrasting the class dimensions of grassroots Christian women’s activism to official denial of the existence of class differentiation or exploitation in this purportedly egalitarian Melanesian state.
