This book focuses on the changes in the identity of Estonian Evangelical Christian-Baptists (ECB) during the Soviet years, 1945-1991. The author analyzed the influences that affected the life and self-understanding of the ECB churches in this most northernmost of the three Baltic countries. External pressures from the Soviet atheistic state and the internal dynamics of Estonian ECB churches are both considered and analyzed. Comparisons are drawn, which show both the similarities with the wider Evangelical world and uniqueness of a local Baptist identity. The book, based on extensive use of archive and other primary source materials, makes an especial contribution to the important emerging field of the study of Evangelicals in Eastern Europe.
