Against this cosmological background Holy Book of the Great Invisible Spirit describes a baptismal ceremony that includes an ecstatic baptismal hymn. It’s claimed that Seth himself has instituted baptism & the baptismal ceremony, & that Seth has become clothed with or incarnate in “the living Jesus.” (I’ve always wondered how Seth can be clothed with or incarnated by the living Jesus, when Jesus hadn’t been born yet? Nor had any prophesy been made about him (Jesus) when Seth was alive.) Jesus IS the manifestation of Seth.
The baptismal ceremony is celebrated in the company of a multitude of heavenly glories, & hymn itself incorporates exalted names, chanted vowels, exquisite epithets, glossolalia (which is the phenomenon of speaking in an unknown language, especially in religious worship. Pretty much it’s the fancy name for speaking in tongues!). & the words of power & praise. The Sethian baptismal ceremony is also mentioned at conclusion of the Secret Book of John, where the text portrays Jesus raising & sealing a person “in luminous water with 5 seals.”
Here, in the Holy Book of the Invisible Spirit, the one who’s undergoing baptism & singing is assuming the name of Jesus & is uniting with Jesus: “‘This name of yours is upon me, you who lack nothing, you self-conceived one, who are close to me. I see you, you who are invisible to all. Who can comprehend you?’ In another voice: ‘Having known you, I’ve armed myself with the armor of light. I’ve become bright. The mother was there for the lovely beauty of grace. So I stretched out my 2 hands. I’ve been formed in the circle of the riches of light in my breast, giving form to the many beings produced in light beyond reproach. In truth light beyond reproach. In truth I shall declare your glory, I’ve comprehended you: yours, Jesus; look, forever O forever E O Jesus O eternal realm, eternal realm, God of silence, I honor you completely.'”
Questions remain about the Sethian baptismal ceremony. How was it performed? How often? To what extent was it spiritualized? Whatever ‘it’ might’ve been, such a baptism was a transforming experience.
The Holy Book of the Great Invisible Spirit is found in 2 Coptic versions in the Nag Hammadi library, as tractate 2 in Codex III & tractate 2 in Codex IV. It was composed in Greek & the circumstances of composition are unknown.
