Moses bar Kepha (d.903), bishop of Mosul, was a prolific writer, whose contributions in the field of exegesis, theology and liturgy are important sources for the theology of the Syrian Orthodox Church. His commentaries on Baptism and Eucharist, making use of early Syriac and Greek writers, have been known to the English speaking world since the beginning of the last century, and provide an example of how later Syriac writers used and reinterpreted earlier sources. Commentary on the Myron is here translated for the first time into English by Fr. Baby Varghese. This book is an invaluable resource for students of Syriac language and literature, as well as those interested in the liturgy.
