This excellent collection surprises at many turns. It offers not only a unique perspective onto a theological dialogue so far unheard, it also opens up new avenues in theological conversation for both participants - the Radically Orthodox and members of the Eastern Orthodox family. Radical Orthodoxy is pushed to articulate a theology of tradition and to locate its own theology of participation within the Patristic patrimony far more deeply than before; the Eastern Orthodox are pushed toward a re-engagment with Bulgakov and the theosophical tradition so attractive to the Radically Orthodox. There is much here for all interested in the future of serious theological dialogue. Lewis Ayres, Candler School of Theology, Emory University This is a stimulating and fruitful exchange between Eastern Orthodoxy and Radical Orthodoxy by leading scholars of each that both draws upon tradition and opens horizons for the future. Addressing the problems of modernity from their different starting points, the collection offers profound material for reflecting upon our own situation. It deserves a wide readership and will amply repay serious engagement. John Behr, Dean, St Vladimir's Orthodox Theological Seminary 'This book has two things to recommend it: the importance of the Eastern Orthodox-Radical Orthodox dialogue which it proposes, and the high quality of the individual contributions. The Eastern Orthodox-Radical Orthodox dialogue promises to enrich contemporary theology and has considerable ecumenical significance.' Modern Theology 'This is an encouraging, demanding and important book, which brings together two traditions sharing much in common radically and traditionally, with significant divergences. The conversation is robust but courteous: this is an academic disputatio, rather than an ecumenical dialogue. I hope that the conversation will remain ongoing.' Modern Believing
