Gnosticism
Gnosticism was an esoteric religious movement, which flourished primarily during the second and third centuries CE, and for a time posed a major challenge to mainstream Christianity. Its adherents claimed to possess a secret knowledge of the divine realms and its inhabitants, and utilized a complex mythology to describe this system. This myth began with the One Unknowable God, then went on to tell of intermediary emanations. One of these emanations, Sophia (Wisdom), desired to know the Unknowable God, but since this desire was illegitimate, what came forth from this desire was an aborted deformity, a being that went forth and created the physical universe. This Creator (or Demiurge) in turn, used the newly created universe to enslave the divine sparks of God into human bodies, where they could only be redeemed by the grace of Gnosis.
