The aim of this study is to describe the traditional Biblical and patristic Amharic commentary material of the Ethiopian Orthodox Church, and to present in translation a sufficient sample of the Amharic, and also the Geez, commentary material, that its character can be clearly seen. Accordingly, the study is divided into three parts - a general introduction, an annotated translation of a Geez commentary, and an annotated translation of an Amharic commentary. The book chosen for parts II and III is the Apocalypse of John.
