This chapter provides an introduction to the phenomenon of eco-anxiety and discusses various proposals that have been made in relation to it worldwide, but the final and constructive part of author text is directed most of all to people in industrialised countries. It describes the Finnish movement related to eco-anxiety, hope, and theology, and provides an agenda for a theology of eco-anxiety. A liberating contextual theology of eco-anxiety recognises the need to encounter dark emotions, and dares to hope and act at the same time. The chapter describes several key points related to various elements of Christian theology and congregational life as regards eco-anxiety and hope. Christian theology and congregations have much experience of living with suffering, practising compassion for those who are in sorrow, and providing people with resources to deal with the fact that they are mortals. The ancient Christian notion of service now applies to both humans and other creatures, towards Creation.
