Every discovery of a scripture from late antiquity is a new opportunity to find out more about what moved man inwardly during that time. The Codex Askewianus, often called the Gospel of the Pistis Sophia, is such a scripture. At first glance, it is a report of a dialogue between Jesus and his disciples. However, nothing is what it seems in the Gospel of the Pistis Sophia. Modern research shows that the writing comes from a community from late antiquity, along with a second writing: the Bruce Codex. They are apparently the testimonies of a mystery school, which are recorded in a very specific form. What distinguishes them from many other mystery schools is their own characteristic spiritual power: Jeu. In the books of Jeu, which are part of the Bruce Codex, this spiritual power creates an important basis for the work of the saviour: the Treasury of the Light. There, light is collected for the Mystery School, for the illumination of its members. Light that awakens the spiritual potential in man.The Gospel of the Pistis Sophia consists of four books, which together form a whole. In the first book the saviour and his disciples are on the Mount of Olives. This is a mythical representation of what takes place during the meetings of the Jeuians: an interaction between a redeeming spiritual power and the growing awareness of the members of the community. They are the candidates on the path of initiation who have opened their consciousness to the saviour. When he has initiated the dialogue, a threefold light comes to him. It surrounds him and shines from him. At that moment he receives the garment of light from the Treasury of Light. This contains all the mysteries, which the saviour explains to the disciples. As a result, they come to a deeper consciousness and, as candidates of the mystery school, are initiated step by step into the mysteries, which are hidden in the garment of light. To reveal these mysteries is the spiritual activity of the mystery school. After this the saviour starts telling the story of the Pistis Sophia. How he finds her under the Treasury of Light, because she has been robbed of her light by the light-robbers of the world below that treasury. The Pistis Sophia begs for the light, but loses it over and over again. In this way she learns to know repentance as an expression of the desire for the light of lights. The saviour intervenes by disrupting the influence of the light robbers in favour of the Pistis Sophia. Everything is accurately
