text_A: Opinions on the devil, and his relationship to the Demiurge, varied. The Ophites would always oppose the assertion that the devil and his demons were constantly frustrating humans, due to their reports that banished the devil to Hell. According to one variant of the Valentinian system, the Demiurge is also the maker, out of the appropriate substance, of an order of "spiritual" beings, the devil, the prince of this world, and his angels. But the devil, as being a "spirit" of wickedness, is able to recognise the higher spiritual world, of which his maker the Demiurge, who is only animal, has no real knowledge. The devil resides in this lower world, of which he is the prince, the Demiurge in the heavens; his mother Sophia in the middle region, above the heavens and below the Pleroma.
text_B: Did the Ophites believe the devil and his demons were frustrating humans?
NO.
