That of Dante was a form of satanism. Gnostic christianity is exorcism because earth forces are evil/demonic that is why the cathars refused to accept this world of matter, they accepted only the spirit world.
Impossible for a dualistic religion like Gnostic Christianity.
How can we see matter and earth forces are evil when we see heaven within us and outside of us?
It seems you have no clue as to what Gnostic Christianity is all about, especially when you talk of Cathars, who do not really exist these days.
