"Meticulously researched and intricately structured, this monograph blazes a new trail in the historiography of the ROC. By reconstructing key formative moments of the church’s experience and action in the early twentieth century, this original analysis gives the reader a more comprehensive sense of context for understanding the ecclesiological identity of the Russian Orthodox today, its relations with the state and its more recent elaborations of the notion of canonical territory. Th is book will be welcomed by specialists and advanced students of the Orthodox Church, but though it is not intended as an introductory text its highly readable presentation will make it very rewarding to the non-specialist as well." - Andrii Krawchuk, St Vladimir’s Theological Quarterly 59:4 (2015) 485–498"This is an important work of scholarship that will serve as a vital reference point for all future research on the international dimension of the Russian Orthodox Church. The book will most definitely be of use to specialists in twentieth-century church history and theologians who focus on modern inter-church relations."James White, Europe-Asia Studies
