The Gnostic Apocalypse of Peter is a text found amongst the Nag Hammadi library, and part of the New Testament apocrypha. Like the vast majority of texts in the Nag Hammadi collection, it is heavily gnostic. It was probably written around 100-200 AD. Since the surviving text, although likely to have been translated from an original Greek version, is in Coptic, it is also known as the Coptic Apocalypse of Peter. The text takes gnostic interpretations of the crucifixion to the extreme, picturing Jesus as laughing and warning against people who cleave to the name of a dead man, thinking they shall become pure.Like some of the rarer Gnostic writings, this one also doubts the established Crucifixion story which places Jesus on the cross. Instead, according to this text, there was a substitute:
"He whom you saw on the tree, glad and laughing, this is the living Jesus. But this one into whose hands and feet they drive the nails is his fleshly part, which is the substitute being put to shame, the one who came into being in his likeness. But look at him and me."
Christology
It is unclear whether this text advocates an adoptionist or docetist Christology, but based on its literary parallels with the Second Treatise of the Great Seth, it may well subscribe to the latter.
