“Sophia” is the “Wisdom of God” personified in scripture…especially in Proverbs.
The Gnostics believed that from Sophia’s desire to return to the Father, she begat from her own volition a being who came to believe he and he alone was the “Only true God”…and through him all the material universe was created…we as spiritual beings have become captive “particles of Light” trapped in this mortality…Jesus crossed the Boundary to give us the True Gnosis, thereby allowing us to be free of the “God of the Blind”…“Samael” or “Ialdaboeth”…
Eastern Christians I believe use the personification of “Sophia” in their spirituality…I’m a bit unclear as to Her role in Eastern Christian religious practice
Some accept Sophia as the “feminine aspect of God”.
Just as Jesus was the personification of God’s Word made flesh…so to is Sophia the personification of God’s Wisdom…in the NT, Jesus is also understood to be the “Wisdom of God”.
