Receptive Ecumenism asks not what other churches can learn from us, but ‘what can we learn and receive with integrity from our ecclesial others?’ Since the publication of Receptive Ecumenism and the Call to Catholic Learning: Exploring a Way for Contemporary Ecumenism (OUP, 2008), this fresh ecumenical strategy has been adopted, critiqued, and developed in different Christian traditions, and in local, national, and international settings, including the most recent bilateral dialogue of the Anglican-Roman Catholic International Commission (ARCIC III). The thirty-eight chapters in this new volume, by academics, church leaders, and ecumenical practitioners who have adopted and adapted Receptive Ecumenism in various ecclesial and cultural contexts, show how Receptive Ecumenism has grown and matured. Part One demonstrates how Receptive Ecumenism itself is capable of being received with integrity into very different ecclesiologies and ecclesial traditions. In Part Two, this approach to transformative ecumenical learning is applied to some recurrent ecclesial problems, such as the understanding and practice of ministry, revealing new insights and practical opportunities. Part Three examines the potential and challenges for Receptive Ecumenism in different international settings. Part Four draws on scripture, hermeneutics, and pneumatology to offer critical reflection on how Receptive Ecumenism itself implements transformative ecclesial learning. Addressing the 70th Anniversary of the World Council of Churches, Archbishop Justin Welby, said that ‘One of the most important of recent ecumenical developments has been the concept of "Receptive Ecumenism"’. This volume provides an indispensable point of reference for understanding and applying that concept in the life of the Christian churches today.
