There are currently four surviving copies of "The Secret Revelation of John". They are largely the same in their basic structure and content. One notable difference between the codices is their individual length. The Berlin Codex and Nag Hammadi Codex III are shorter than the Nag Hammadi Codices I and II. Another point of departure between codices is the portrayal of the Savior/Christ figure. The Berlin Codex generally uses the term “Christ” more frequently, whereas the Nag Hammadi Codex III narrative often substitutes the term “Lord” or “Savior”. However, the Nag Hammadi Codex III closes its text with the prayer “Jesus Christ, Amen.” An additional distinction, with regards to the Christian framing of the texts, is that Nag Hammadi Codex III goes into greater detail about the descent of the Christ/Savior figure into the prison-world of Demiurge and his role in facilitating the reawakening and liberation of mankind. These distinctions may represent a certain degree of variation in the way that Gnostic cosmology was woven into a Christian context.
