The Gnostic Crucifixion [EPUB ebook] 

The Gnostic Mystery of the Crucifixion is most clearly set forth in the new-found fragments of The Acts of John, and follows immediately on the Sacred Dance and Ritual of Initiation which we en deavoured to elucidate in Vol. IV. of these little books, in treating of The Hymn of Jesus.
The reader is, therefore, referred to the “Preamble” of that volume for a short introduction concerning the nature of the Gnostic Acts in general and of the Leucian Acts of John in particular.
