The first part of the gospel of truth from tbe Nag Hammandi collection. This is possibly written by Valentinus (the monist gnostic teacher).
(Start of the text)
The gospel of truth is joy to those who have received from the Father of truth the gift of knowing him by the power of the Logos, who has come from the Pleroma and who is in the thought and the mind of the Father; he it is who is called “the Savior,” since that is the name of the work which he must do for the redemption of those who have not known the Father. For the name of the gospel is the manifestation of hope, since that is the discovery of those who seek him, because the All sought him from whom it had come forth. You see, the All had been inside of him, that illimitable, inconceivable one, who is better than every thought.
