While I have no idea why you went down this road, you have chosen the wrong definition for the suffix of ism. In this instance, it is a distinctive doctrine, cause, or theory, thus Gnosticism, the idea that only through attaining secret knowledge can people find their salvation and overcome the material world. It is not a process as defined, but a doctrine, one deemed hetertical by the Christian Church.
And I’m not sure how the rest of your thoughts follow.
May I ask about your higher education?
You may ask about my higher education, but I don't see how that should be relevant to the discussion.
I was replying to Elexir's comment about changing the term used for gnostics, so gnosticism is a distinctive doctrine or theory, but it's also the art, practice, or process, of KNOWING.
The idea you've outlined about it is right, and if the Christian Church deemed it heretical, it must be good.
