s/t: A History of the Development of Doctrine
The line that separated Eastern Christendom from Western on the medieval map is similar to the "iron curtain" of recent times. Linguistic barriers, political divisions & liturgical differences combined to isolate the two cultures from each other. Except for such episodes as the schism between East & West or the Crusades, the development of non-Western Christendom has been largely ignored by church historians. The Spirit of Eastern Christendom explains the divisions between Eastern & Western Christendom, & identifies & describes the development of the distinctive forms taken by Christian doctrine in its Greek, Syriac & early Slavic expression.
