Though discovered in 1945, the First Apocalypse of James from Nag Hammadi Codex V, 3 has received very little attention from the scholarly community. This is primarily due to the fragmentary condition of the text. Previous scholarly engagements with the text have led to the conclusion that the purpose of such a revelatory dialogue was to impart instructions for the ascent of the soul to one about to be martyred. The recent discovery of a second copy of the text simply titled “James” as part of the Tchacos Codex has led to not only a greater amount of scholarly interest, but also to different possible interpretations. From NHC V, 3 it was possible to ascertain a pre- and post- martyrdom revelation of Jesus to James, however, the text from Al Minya clearly shows a third revelatory section wherein the martyrdom of James is used as a means of revelation to Addai, the legendary founder of Eastern Syrian Christianity. Chapters one and two answer the question of why James was chosen as the protagonist of the narrative. In chapter one I look in detail at the literary construction of the martyrdom of James and problematize the development of the traditions. Chapter two then turns to a discussion of the figure of James as an authority in the developing Christian community. Chapters three and four are concerned with the literary classification of the text. Chapter three situates the First Apocalypse of James within the overarching genre of apocalyptic literature, and the specific sub-genre of gnostic apocalypses. Chapter four discusses how the text might be understood as a commission narrative while interrogating the lineage of descent beginning with the transmission of the revelation from James to Addai. Following this in chapter five I explore the cosmology of the text with particular attention to the ascent of the soul.
