Throughout the rich history of Bible research and patrology, a palet of different traditions has always existed. One of these, which is based on an abundant manuscript tradition of biblical and patristic interpretation, is the tradition of the Eastern Orthodox Church. In this book a liturgico-codicological approach to the Byzantine biblical and patristic manuscripts is set out. This approach offers a key to understanding the position of the biblical and patristic writings in the Eastern Orthodox Churches. It stems from what is termed a ‘liturgical hypothesis’ and implies the necessity of a thorough reclassification of the extant manuscripts.
