The Hypostasis of the Archons
(The Reality of the Rulers)
On account of the reality of the authorities, (inspired) by the spirit of the father of truth, the great apostle – referring to the "authorities of the darkness" – told us that "our contest is not against flesh and blood; rather, the authorities of the universe and the spirits of wickedness." I have sent this (to you) because you inquire about the reality of the authorities.
