'This volume assembles a star-cast of international scholars- Orthodox, Catholic and Protestant - to reflect on current transformations in Trinitarian theology and to assess the implications of these debates for church and society. Precisely because the contributors manifestly do not agree on some central areas of contention, the volume catches a moment of significant theological transition and provides an invaluable resource for ecumenical debate, discussion and teaching. The editors are to be congratulated on their choice of materials'. - Sarah Coakley, Norris-Hulse Professor of Divinity, University of Cambridge
