Union Without Confusion

 
IOCS is proud to host on Tuesday 30 June 2026 the UK book launch of the important work by Prof Peter Bouteneff, “Union Without Confusion: Councils and Christology Beyond the Chalcedonian Divide”, in-person at Trinity College, Cambridge. The event will begin with a presentation from the author, a response from the Coptic Archbishop Angaelos of London and member of the board of Trustees will then follow.
 

This book offers a fresh perspective on the conciliar era, exploring the separation between Eastern and Oriental Orthodox post Chalcedon. it examines the theological formulations of the seven great councils alongside other key writings- presented here in Greek with English translations. It invites a reconsideration of figures long revered or rejected by the different churches, and traces how Greek philosophical terminology was gradually reshaped to express Christian belief-a process that took different forms across the diverse regions in late antiquity. More than a reappraisal of the past, this study challenges readers to reflect on the nature of patristic authority, and its enduring implications for theology and the restoration of communion among the churches.
