Widely considered the most important Orthodox theologian of the twentieth century, Dumitru Staniloae (1903-1993) contributed significantly to an ecumenical understanding of these themes. Because of his isolation by the Romanian Communist regime, his work still awaits its merited reception, especially given its potential contribution towards Christian unity. In Staniloae's understanding the Church is a communion in the image of the Trinity. Because there is a continuum of grace between the Trinity and the Church, the same relationships that exist among trinitarian persons are manifested in creation in general, and the Church in particular. In this way, the Trinity fills the world and the Church, determining their mode of existence. Intratrinitarian relationships are manifested in the relationships between humankind and non-human creation, the Church and the world, local and universal aspects of the Church, clergy and the people, and among various charisms.

Dumitru Stăniloae is one of the most important but routinely neglected twentieth-century Orthodox theologians. Viorel Coman explores the ecumenical relevance of Stăniloae’s reflections on the interplay between the doctrine of the Trinity and the doctrine of the church in the context of the debates on the ecclesiological ramifications of the filioque. Coman combines a historical and theological analysis of Stăniloae’s approach to the filioque, Trinity, and church. The historical analysis shows the changes that have taken place over time in Stăniloae’s approach to the issue of the filioque and the doctrine of the church. The theological analysis emphasizes the ecumenical contribution of the Romanian thinker to the fields of Trinitarian theology and ecclesiology. Even though this book centers primarily around Stăniloae’s vision on the link between the doctrine of the Trinity and the Church, it places his theological reflections in a solid dialogue with other Eastern (Georges Florovsky, Vladimir Lossky, and John Zizioulas) and Western theologians (Karl Barth, Yves Congar, Karl Rahner, and Walter Kasper).

In the second volume of her Essays in Ecumenical Theology, Ivana Noble engages in conversation with Orthodox theologians and spiritual writers on diverse questions, such as how to discover the human heart, what illumination by the divine light means, how spiritual life is connected to attitudes and acts of social solidarity, why sacrificial thinking may not be the best frame for expressing Christ’s redemption, why theological anthropology needs to have a strong ecological dimension, why freedom needs to coexist with love for others, and why institutions find the ability to be helpful not only in their own traditions but also in the Spirit that blows where it wills.

The dominant contemporary model for ecclesiology (theological views of the church itself) is the ecclesiology of communion. MacDougall argues that communion ecclesiologies are often marked by a problematic theological imagination of the future (eschatology). He argues further that, as a result, our ways of practising and being the church are not as robust as they might otherwise be. Re-imagining the church in the light of God's promised future, then, becomes a critical conceptual and practical task. MacDougall presents a detailed exploration of what communion ecclesiologies are and some of the problems they raise. He offers two case studies of such theologies by examining how distinguished theologians John Zizioulas and John Milbank understand the church and the future, how these combine in their work, and the conceptual and practical implications of their perspectives. He then offers an alternative theological view and demonstrates the effects that such a shift would have. In doing so, MacDougall offers a proposal for recovering the 'more' to communion and to ecclesiology to help us imagine a church that is not beyond the world (as in Zizioulas) or over against the world (as in Milbank), but in and for the world in love and service. This concept is worked out in conversation with systematic theologians such as Jürgen Moltmann, Wolfhart Pannenberg, and Johannes Baptist Metz, and by engaging with a theology of Christian practices currently being developed by practical theologians such as Dorothy C. Bass, Craig Dykstra, and those associated with their ongoing project. The potential for the church to become an agent of discipleship, love, and service can best be realised when the church anticipates God's promised perfection in the full communion between God and humanity, among human beings, within human persons, and between humanity and the rest of creation.

In recent bilateral ecumenical dialogue the aim of the dialogue has been to reach some form of doctrinal consensus. The three major chapters of the book discuss the variety of forms of doctrinal consensus found in ecumenical dialogues among Anglicans, Lutherans and Roman Catholics. In general, the dialogue documents argue for agreement/consensus based on commonality or compatibility. Each of the three dialogue processes has specific characteristics and formulates its argument in a unique way. The Lutheran-Roman Catholic dialogue has a particular interest in hermeneutical questions and proposes various forms of "differentiated" or perspectival forms of consensus. The Anglican-Roman Catholic dialogue emphasises the correctness of interpretations. The documents consciously look towards a "common future", not the separated past.

Das Attribut "katholisch" wird in vielen Kontexten als Konfessionsbezeichnung einer bestimmten Kirche missverstanden. Die in diesem Band vorgelegten Vorträge der 18. Wissenschaftlichen Konsultation der Societas Oecumenica beleuchten die ökumenische Bedeutung der "Katholizität" die alle Kirchen im Glaubenbekenntnis bekennen. Dabei werden auch die Spannungen zwischen Einheit und Viefalt sowie die Herausforderungen durch neuere Entwicklungen in der weltweiten Christenheit in den Blick genommen. In many contexts the attribute "catholic" is misunderstood as a confessional term describing one specific church. The papers of the 18th Academic Consultation of Societas Oecumenica presented in this book give insights to the ecumenical significance of the "catholicity", which all churches confess in the Creed. They also take into consideration the tensions between unity and diversity as well as the challenges by new developments in worldwide Christianity.

The Promise of Ecumenical Interpretation achieves its ecumenical goals by returning to the unifying force of the Bible itself. The authors--one Protestant, one Catholic, one Orthodox--agree that consensus about the Bible is tied to the centrality of the Bible for the individual believer and the life of the church.

The Oxford Handbook of Ecumenical Studies is an unparalleled compendium of ecumenical history, information and reflection. With essay contributions by nearly fifty experts in their various fields, and edited by two leading international scholars, the Handbook is a major resource for all who are involved or interested in ecumenical work for reconciliation between Christians and for the unity of the Church. Its six main sections consider, respectively, the different phases of the history of the ecumenical movement from the mid-nineteenth century to the present; the ways in which leading Christian churches and traditions, Orthodox, Anglican, Methodist, Catholic, Lutheran, Reformed, Baptist, and Pentecostal, have engaged with and contributed to the movement; the achievements of ecumenical dialogue in key areas of Christian doctrine, such as Christology and ecclesiology, baptism, Eucharist and ministry, morals and mission, and the issues that remain outstanding; various ecumenical agencies and instruments, such as covenants and dialogues, the World Council of Churches, the Pontifical Council for Promoting Christian Unity and the Global Christian Forum; the progress and difficulties of ecumenism in different countries, areas and continents of the world, the UK and the USA, Africa, Asia, South America, Europe, and the Middle East, ; and finally two all-important questions are considered by scholars from various traditions: what would Christian unity look like and what is the best method for seeking it? This is a remarkably comprehensive account and assessment of one of the most outstanding features of Christian history, namely the modern ecumenical movement.

The present volume unites 44 studies to honor Prof. Dr. Dorin Oancea, Romanian-Orthodox theologian and religious studies scholar, well known as a bridge-builder between Eastern and Western Christian Traditions. The manifold studies reflect upon the fundaments of interfaith and inter-confessional openness, offer insightful examples from past and present, or point to the loci where this openness can and should be achieved today. A meaningful collection for all those interested in present day ecumenical theology, in inter-confessional studies or theology of religions.
