The manuscript itself has been dated to the 4th century, although it is possible that it is a transcription of an earlier document. Most scholars argue that the text is of gnostic origin based on the similarities between the mystical teachings found in the text and standard Gnostic themes. The Sophia purports to be a conversation between Jesus and his disciples after his resurrection from the dead. Highly mystical, this content of this text concerns creation of gods, angels and the universe with an emphasis on infinite and mystical truth.
The debate about dating is critical since some argue that they reflect the 'true, recorded, sayings' of Jesus Christ, which is conceivable if in fact they do date back as far as the 1st century. Others argue that they are in fact considerably later and an unreliable secondary source, at best post facto hearsay.
