The Cascadia bioregion - British Columbia, Washington, and Oregon - has long been at the forefront of cultural shifts occurring throughout North America, in particular regarding religious institutions, ideas, and practices. Religion at the Edge explores the rise of religious nones, the decline of mainstream Christian denominations, spiritual and environmental innovation, increasing religious pluralism, and the growth of smaller, more traditional faith groups. The first research-driven book to address religion, spirituality, and irreligion in the Pacific Northwest, past and present, Religion at the Edge expands our understanding of the nature, scale, and implications of socio-religious changes in North America, and the relevance of regionalism to that discussion.
