The book of the Serbian hieromonk Savva (Janjic), whose original title is “Ecumenism and the Time of Apostasy,” gives a detailed historical picture of the development of apostasy in universal Orthodoxy, predicted for the end of times. This sad process began in the Patriarchate of Constantinople and gradually affected all local Churches, including the Serbian Church, to which the author of the book belongs, and the Russian Church, in which the church people are waging a stubborn struggle for its recovery. The publishers of this Russian translation would like to make their contribution to this fight. Cover photo: Patriarch Bartholomew of Constantinople and Cardinal Edward Cassidy
