“The book offers a broad spectrum of movements which are little-known in the West. The contributors try to clarify phenomena from the perspective of the anthropology of religion and they give few theological insights. … This volume will certainly become an impetus for future publications in this field.” (Sergiy Sannikov, European Journal of Theology, Vol. 28 (1), 2019)“This volume is a must for those who have an interest in what ‘spiritual renewal’ looks like in an Eastern Orthodox context. It is my hope that it is only the first of many other similar studies that will be made available to the English-speaking world.” (Timothy Cremeens, Pneuma, Vol. 40 (4), 2018)
