For the Unity of All offers significant and new contributions for the furthering of dialogue and the path to unity between East and West. In this excellent example of ecumenical theology, the author utilizes the resources of contemporary philosophy in an effort to shed some new light on centuries-old debates that perpetuate the division between the Christian churches. ""One of the most significant issues embraced in recent years by the joint international commission for this dialogue has been the difference in methodological and theological approaches to primacy in the Church. This book contributes to the ongoing discussion of this crucial topic."" --from the Foreword by Ecumenical Patriarch Bartholomew, Archbishop of Constantinople ""A timely and important contribution to the ongoing theological dialogue between Roman Catholicism and Orthodoxy. Father Manoussakis discusses in depth some of the crucial theological and philosophical issues that have traditionally affected the relations between Eastern and Western Christianity and throws new light on them, enabling us to approach them in a constructive way."" --John (Zizioulas) Senior Metropolitan of Pergamon, author of Being as Communion ""Manoussakis makes a significant and long-awaited contribution to the ecumenical dialogue between the two churches--a contribution that I expect to have a very considerable impact on the ongoing theological dialogue as well as on the academic fields of ecumenical theology in general. There is an urgent and immediate need for a book of this kind at this critical historical and intellectual juncture of dialogue between the major Christian churches. Manoussakis's intervention is patient, passionate, and prophetic."" --Richard Kearney, author of Anatheism ""This author is uniquely situated, linguistically, culturally, philosophically, and theologically, not so much to solve problems which have separated sister churches for over a thousand years, as to dissolve them. This book, slender as it may be, is a blockbuster."" --Mark Patrick Hederman, Abbot of Glenstal, Murroe, Ireland The Very Reverend John Panteleimon Manoussakis is Associate Professor of Philosophy at the College of the Holy Cross and Honorary Fellow at the Faculty of Theology and Philosophy of the Australian Catholic University. He is the author of God After Metaphysics: A Theological Aesthetic (2007) and editor of five volumes, and he has published over thirty articles in English, Greek, Russian, Serbian, and Ukrainian.
