Is There a Gnosticism?

Gnosticism lost control for the battle of christianity and the proto orthodox church. Eventually, the catholic church won out and got to dictate what theology was across the roman empire. But i think there is now an emerging strand of historical thought ht says that's maybe not the case. It's more like gnostic ism, as a named thing lost power. But it also, in a way, got to define the path ofchristianity in doing so.
