This book is a textual commentary on the critical edition of the Gospel of John in Ge'ez by M.G. Wechsler, Evangelium Iohannis Aethiopicum, Leuven (2005). This text was compared with the Greek, Latin, Syriac, Coptic, Armenian, Georgian versions and with different versions of the Diatessaron. In this there appears how the Old - Ethiopic is an important textual witness of the New Testament. In its oldest form it reveals a certain liberty in rendering of the text which makes it affiliated with the other old text-forms, as there are the Old Syrian Sinaï and Cureton manuscripts and the Georgian Adish - manuscript en the Lectionary of Paris. The most striking is its affiliation with the Diatessaric traditions.
