"There is no doubt that Sergeev’s theory of religious cycles and his philosophical, sociological and political analysis of the evolution of religion, presents a significant scholarly value, not only in theological but also in philosophical and sociological contexts, because ... it sets the landmarks of understanding and reinterpretation of pressing problems of modern humanity." - Natalya Shelkovaya"It should be acknowledged that Mikhail Sergeev’s book is undoubtedly a profound and thorough scholarly work, based on a wide range of sources. Not only is it a valuable contribution to studies in the evolution of human religious and social consciousness, but it also outlines possible perspectives for that evolution in the future." - Youli A. Loannesyan"[T]his is an extremely important book in understand that religions change or evolve according to a precise system of phases. Sergeev has argued clearly, too, that this evolution comes not from a simplistic "decline in faith", but from a highly complex series of interactions between texts, traditions, and believers, and the forces of modernity and cultural change." - Benjamin B. Olshin, The University of the Arts"In this insightful and provocative book, Sergeev creatively takes the reader through the world religions, with a remarkable and easy-to-understand table of comparisons at the end. It shows not only his deep interest in religions but also a fair and accurate understanding of the Bahá’i Faith, which takes up a major part of this book. ... In my opinion this book provides the best bridging of religious changes I have read. It is more relevant now than any time since the Enlightenment, so is highly recommended." - Gity Banan Etemad, Temple University, Philadelphia, PA
