Most are not ready to think deeply enough about reality.
The modern Gnostic Christian view on evil matter is that matter is not evil. It is evolving perfection.
We never really believed matter was evil but unfortunately the language of that day used the term evil. Gnostic Christians could not believe matter was evil because we believe that we have a spark of God within our bodies, (matter), and the kingdom of God is both within us and around us as Jesus taught.
Luke 17:21 Neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is within you and around you.
Gnostic Christians of that day were into duality of matter and non-matter. As above so below.
Above would have been seen as perfect while here below, at that time, Gnostic Christians did not see perfection. It was thus said that it was good above and evil below.
Modern Gnostic thinking has evolved somewhat and we now say that matter is evolving perfection. Many think this quote was not written seriously but to a Gnostic Christian it will be understandable as a truth.
Candide.
"It is demonstrable that things cannot be otherwise than as they are; for as all things have been created for some end, they must necessarily be created for the best end.”
This means that we all live in the best of all possible world and that is why modern Gnostic Christians call what we have around us, evolving perfection.
Be you a believer or not, the notion that things cannot be other than what they are and are, evolving perfection is irrefutable even though it is a fairly hard concept to grasp. This does not mean that we cannot improve as we each evolve further.
