Didn't Divine Magic start with Gnosis 40 allready
*no rulebook at hand*
Also, Gnosis is pretty much enlightment in translation. It describes how much a character has evolved out of the life apparatus and has gained oversight above the "how" and "why" everything functions.
Normal people with gnosis 0 are bound to destiny in form of a higher will, while heroes with a score of 10 have the potential to make their own way and sometimes change how things were somehow meant to be. Also they occasionally are able to percieve if some higher being was just adjusting the reality to his will a bit (at least they sense that "something is odd").
A being with gnosis 25 is so enlightened allready that it can start to form out his own identity with his will to something more personal to your spirit (remember, we are on the way where you would be a deity with gnosis 50 at the end, and where you would then represent a certain aspect in life that you have chosen - as every other deity does). With the access to monsterpowers really everything becomes possible. If you want to have crazily fast regeneration? - do it. Your own non-magic/non-Ki special attack, named "Napalm Horror Finger Jab!!" or "Lord Basil tells you how it is" or something? - your choice. Just a matter of enough DP by now.
This state is for me a reflection of the usual main villain in a rpg, who normaly runs some absolutly non-canon powers, that players usually can't get by following the system.
Gnosis 35 makes you a demigod in gameterms. Your perception of reality and how the things flow is allready so advanced, that you can literally influence it with your willpower in some minor ways - "Would be so nice if they just left the key he.. , nice, thanks!"
Being allready crystallized out from the flow of souls somehow, you also cannot be killed so easy anymore. In fact you reincarnate all the time if it was just a being with 30 or more less gnosis than you were killing you (meaning only heros can really kill a demigod).
Gnosis 40 makes you a mundane deity with I believe(not sure at the moment) access to all kinds of magic which literally lays the tools of creation, life, time and doomsday in your hands.. (there is a spell named "Armageddon".., yepp). Your natural abilty to influence reality is so intuitive now, that mere thoughts are enough to adjust reality in your favor all the time
, giving you insane advantages against any lesser enlightened being and making all not knowledge related tasks often so easy as snaping your fingers. You imagine how it should be and there it goes.
I like to compare this level as the final boss state of every final fantasy game, where the last enemy has multiple mutation phases and usually alot of unfair and for players normally unachievable powers. You can often observe there how these last villains have a certain degree of reality altering powers, running some will telekinesis, darkening the skies, floating and stuff like that (not to mention their personal world scaled special attacks
Oh, yes and you can raise avatars of yourself which can handle things for you at a distance in a very deity-ish manor.
Gnosis 45 is what I would call the bestia and summon state in a final fantasy game, because it enables you to shift between the multiple layers of reality at any time (so without any spell, power or so), so you can appear and reappear as you please. At this moment you are a not earthbound minor deity that can allready represent some minor aspect of reality by himself (and if it is just being the king/prototype of all dragons "Bahamut", or the incarnation of the early mornings dewdrops on the leaves). But this is just my interpretation - I have not seen jet any example sheet of a character or creature with gnosis 45.
Gnosis 50 is the god state obviously. Choose your aspect and make your vote / give your influence on how the life apparatus should run.
///Disclaimer: I didn't want to say you can actually "evolve" by the rules. It is just good for the description I think.
This stays a GM (and players) thing as it is so often.
