""Antoine Arjakovsky's unique experience with practical ecumenical engagement in various cultural and geographical contexts, particularly those of Eastern Christianity, shines through in his book.""-YURY P. AVVAKUMOV, University of Notre Dame ""Antoine Arjakovsky's stimulating interdisciplinary reflection invites readers to reconsider the movement towards unity in light of a true 'ecumenical metaphysics'-ecumenism as the unity of all in all, and not merely as the unity of Christians.""-HYACINTHE DESTIVELLE OP, OEcumenicum, Angelicum, Rome ""In this seminal essay on ecumenical metaphysics, Arjakovsky provides a masterful review of decades of literature, theological reflections, historical narratives, philosophy, and much more, to share the foundation of a 'new understanding of reality, of a new epistemology, both trans-disciplinary and trans-confessional but also trans-religious and trans-convictional.'""-AZZA KARAM, President and CEO, Lead Integrity ""Arjakovsky moves across history and disciplines to develop an ecumenical metaphysics as a sapiential compass both personal and universal, participatory and collaborative, to help us think through the challenging problems of our age.""-LISA RADAKOVICH HOLSBERG, Fordham University ""What is Ecumenism? can serve as a starting point for fruitful dialogue about how to bridge the divides between people, nations, and religions.""-ZDZISLAW SZMAŃDA OP, Saint Thomas Aquinas Institute, Kyiv
