The Anthropocene Era, our current epoch of climate change, biodiversity loss, and human dislocations of many kinds, can bring fear, confusion, despair, and anger. This book of letters invites you to an understanding of the gospel as a way of life that can support and ground our action and witness in this time of intensifying polycrises. Consistent with current science, it speaks as well the languages of spiritual life and the imagination. It draws from a wide range of sources from the Christian tradition, including some Quaker practices for spirituality in action. Illustrations and meditations support an encounter with the living book of nature. Reflection queries are offered to support conversation and spiritual formation.
