Where did the doctrine of the Dormition of the Mother of God-the Theotokos-come from, and how did it become integral to Eastern Orthodox Christian worship? Dr. Michael Tsichlis surveys this important but little known subject in a way that is scholarly and thorough as well as accessible to the average layperson. Dr, Tsichlis traces the historical development of the Dormition as a phenomenon which ultimately reflects the source of our salvation: Jesus Christ.
