The chapter surveys the statements and initiatives on ecology developed within and issued by the World Council of Churches, the Ecumenical Patriarchate of Constantinople, and the Roman Catholic Church. It finds care for creation to be a concern to which churches have responded both through individual initiatives and by ecumenical dialogue. It identifies 1989–1990 as a watershed when statements and initiatives began to develop ecological teachings centred on the creative activity of the Trinity, the responsibility of members of the church as stewards and priests of creation, and the centrality of prayer and liturgy—especially the Eucharist—in care for creation. Finally, it indicates avenues for further ecumenical dialogue and offers suggestions for action, focusing in particular on sacramentality and a sacramental view of the world, and highlighting the ecclesiological importance of contributions, initiatives, and statements from local churches.
