Book excerpt: John D'Arcy May's achievements motivate these essays on ecumenics. Amid today's scepticism about the ecumenical movement's relevance, the authors demonstrate the necessity of working together for the betterment of all. This book deepens our understanding of how theology, peace and reconciliation studies and interfaith dialogue critically cooperate for the flourishing of earth's life. The perspective of church unity amid ecclesial division is broadened to embrace interfaith and intercultural issues: ecumenics becomes visible as the intellectual paradigm of our times.
