Severus of Antioch is by far the most prolific and well known theologian of the non-Chalcedonian churches. Although his life and writings came to our knowledge in Syriac, gaining him the title "Crown of the Syriac Literature," many texts relating to his life and works survived in the Coptic and Copto-Arabic tradition, as well as a number of other texts that were traditionally attributed to him. This book provides an analysis of the remaining texts in Coptic and in Copto-Arabic, as well as the texts ascribed to Severus. The last part of the book deals with the veneration of Severus of Antioch in the Coptic Church.
