I would like to clarify that:
1-Gnosticism is a TYPE of religion., an umbrella term like “Pagan” or “Abrahamic”. Thus one can seldomly say “Gnostics think”.
2-Not all Gnostics are Christians.
3- Sophia did not create the material world directly, Yaldabaoth / The Demiurge (“God”) did (but she created him, herself being the lowest “Aeon”, the highest being Bythos – Profoundness, an impersonal, trancendent God, not responsable for creation).
4- Christos in Gnosticism is a VERY different figure than in Nicean generated Christianity.
5- Gnostic gospels are regarded as allegory, NOT history and mytopoeia is encurraged.
