This is the first English translation of the work of fourth-century theologian, Ephrem the Syrian, on the Diatessaron--a text woven from the four Gospels, which predates the earliest-known evidence of the official Syriac translation of the New Testament. Epohrem's commentary on the Syriac text of Tatian's Gospel Harmony has a two-fold value for the modern scholar ... it marks a foundational stage of biblical interpretation in the Syriac Church .,.. its other importance is as a vital textual witness to the Syriac Diatessaron text .... Sr McCarthy has provided a very clear and helpful English translation of the MS.
