I'll use the first paragraph of that Wikipedia article:
Gnosticism (from Ancient Greek: γνωστικός, romanized: gnōstikós, Koine Greek: [ɡˠno̞s.tiˈkos], "having knowledge") is a collection of religious ideas and systems which originated in the first century AD among early Christian and Jewish sects.[1] These various groups emphasised personal spiritual knowledge (gnosis) over orthodox teachings, traditions, or the authority of the church. Viewing material existence as flawed or evil, Gnostic cosmogony generally presents a distinction between a supreme, hidden God and a malevolent lesser divinity (sometimes associated with the Yahweh of the Old Testament)[2] who is responsible for creating the material universe.[3] Gnostics considered the principal element of salvation to be direct knowledge of the supreme divinity in the form of mystical or esoteric insight. Many Gnostic texts deal not in concepts of sin and repentance, but with illusion and enlightenment.[3]
Gnosticism Didn't Exist (Say What Now?) • Richard Carrier
A rather startling conclusion.It’s scandalous to say, because so much pop theorizing about early Christianity is anchored to it, but it turns out, Gnosticism was never actually a thing. It was an invention of modern scholars; an interpretive category, it turns out, that refers to no actual thing that existed in antiquity. Or worse, when defined vaguely enough to actually encompass anything real, it refers to every sect of Christianity and thus distinguishes none of them. The word is therefore useless and ought to be abandoned. I find myself having to point this out a lot, so clearly this memo hasn’t made it to the public yet. So I am writing this article to get you up to speed.
I came to this conclusion on my own, from my extensive postdoc research project on the historicity of Jesus. Which is why (in case readers didn’t notice) the words “Gnostic” or “Gnosticism” never appear anywhere in my book On the Historicity of Jesus (except incidentally as the title of a couple of books I cite, but not on that subject). I never use Gnosticism as an interpretive category there, or as an explanation of anything. And yet, as soon as that was published, the Westar Institute (best known for The Jesus Seminar, and of which I am now a fellow) published a report declaring the same thing, and on the same basis. That a large group of prestigious Biblical scholars independently came to the same conclusion I did, and for pretty much the same reasons I had uncovered on my own, is fairly powerful evidence we are correct about this. The odds of that all happening by coincidence are pretty low.
