As the Gnostic Mass begins the woman in the role of the priestess waits out of sight. The congregation recites the Gnostic Creed. When I am priestess I quietly recite the creed along with them. Just before I enter the temple I recite this prayer to help me transition from my everyday self to the ritual role.

Oh Nuit
Grant that I may be a worthy vessel to be your priestess.
I empty myself of me
to make space for thee.
Let enough of me remain
that I may perform the actions and words of this Mass correctly.
When these are complete
I empty myself of me entirely
so that only thee remains.
