“The paperback edition is a valuable and affordable resource, which I recommend as a compendium for historians, religionists, and theologians alike.” (Religious Studies Review, 4 June 2015)
“In short, this Encyclopedia, is a useful tool that offers valuable basic information on many aspects of the Orthodox world.” (Journal of Eastern Christian Studies, 1 March 2014)
“The encyclopaedia as a whole is a remarkable achievement: not, perhaps, completely reliable, but nothing is. The preface by the editor, Fr John McGuckin, is a masterpiece.” (Theology, 1 September 2012)
“His monumental work and Leustean’s indispensable reference book provide a wealth of knowledge about global Orthodoxy during historical cycles of growth, repression and renewal.” (European History Quarterly, 2012)
“By this token, then, the encyclopaedia is a timely value for money product, for those with deep pockets and deep minds.” (Reference Reviews, 2012)
"The stated intention of producing an authoritative, scholarly reference work has been realized in a work that will have the greatest utility for researchers at every level. In 30 years of studying Orthodox Christianity, this reviewer has been no comparable work. Summing Up: Essential. Reference collections supporting lower-level undergraduates through researchers/faculty, and general readers. " (Choice, 1July 2011)
"In the preface editor McGuckin expresses his joy in bringing together this two-volume reference - a resource that breaks ground by making accessible comprehensive coverage of a religion that is rising once again after enduring some of the greatest challenges of its history - the 20th-century repressive regimes of eastern Europe." (Booknews, 1 April 2011).
